***VIA Debuts Tablet PC Design at WinHEC
VIA Technologies, Inc, a developer of silicon chip technologies
platform solutions, today demonstrated its new VIA Tablet PC design at
WinHEC 2002 event in Taipei, Taiwan.
The VIA Tablet PC design is a slate-style portable PC, combining
'digital ink' system with a 10.4" electro-magnetic digitizer portrait
screen to form a digital notepad. Less than one inch thick and weighing
just over one kilogram, the VIA Tablet PC design is lighter and less bulky
than most laptops. It supports the full functionality of Microsoft
Windows XP Tablet PC Edition, as well as a connectivity features including
USB 2.0, IEEE 1394 and optional 802.11b wireless support.
The VIA Tablet PC design utilizes an array of VIA's low
technologies, including a choice of the VIA C3 EBGA and the VIA Eden ESP
processors, as well as the VIA Apollo Pro266T DDR SDRAM chipset. This
longer battery life and quieter operation, and reduces system cost.
At the heart of the VIA Tablet PC design is the VIA Apollo
double-sided mainboard specifically designed by VIA for thin and light
portable applications. It is powered by a choice of VIA C3 or VIA Eden
processors, which have highly efficient thermal properties that enable
passive 'fanless' cooling. The main board also includes the VIA Apollo
Pro266T chipset, with support for high bandwidth DDR SDRAM memory running
at 2.5 volts compared to 3.3 volts for standard SDRAM.
I/O integration affords a variety of connectivity options,
speed USB 2.0 and IEEE 1394 ports, a PCMCIA slot, a RJ-45 port, and
infrared functions. VIA companion chips are incorporated into the VIA
Tablet PC design; for example, networking capabilities are enabled through
the VIA Tahoe VT6103, onboard audio through the VIA 6-channel audio codec,
and IEEE 1394 capability with the VIA Fire II VT6306.

0217.2 Story of the Issue
by John Latta
NGN Ventures, like its sister conference NGN, continues
to be one of the
best conferences in networking technology and economics. John McQuillian
brings his keen industry insights and blunt assessments into a conference
forum not heard in other venues. Unfortunately the economics of the
industry impacted this event. We estimate the attendance was 50% to 60%
last year. As John stated, we are in a telecommunications depression.
Everyone is feeling the pain. Yet, there continues to be promising
technologies. We also experienced wonderment at how start-up companies
have adapted and try every trick in the book to stay alive as they look
for signs of an upturn.
Here at the NGN Ventures conference the emphasis is on early-stage
companies. There are two high points of each event: the industry overview,
with which John begins the conference, and his summary at the end. The
scope of NGN is so large and the technology and economic environment
sufficiently dynamic that the focus of these events change from year to
year. One year considerable time may be devoted to ATM and another year
IP converged networks. This year the emphasis is less on the ILEC vs.
competitors, given that virtually all the DCLECs have died, and more on
emerging markets such as seamless wireless connectivity and multi-service
Networking Economy Continues to Slide
At NGN in Boston about 6 months ago the state of the networking
was grim now it is depressing. Here are statements made during the first
days events, mostly by John McQuillian.
IT is no longer a growth industry but a mature one (Reference
the state of IT stocks).
Networking is no longer a growth industry but a replacement
We need to stop saying this is a tough market.
We should be
saying this is the market.
Capital expenditures in the telecommunications sector fell
30% in 2001 and will fall another 30% in 2002. Buyers have
deep pockets but short arms.
We are also suffering from a failed public policy in
In one year $1T in market value was lost in the networking
and telecommunications sector, and in the NGN market sector
in one year the value went from $500B to $40B.
On the venture investing side it is even worse. VC backed
startups that went public numbered the following:
2002 4 (to date)
VCs are even returning funds to Limited Partners because
cannot invest funds with a probability of return.
The incumbent players in telecommunications, i.e. ILECs,
in the drivers seat and have no competitive pressure.
It remains to be seen if the Internet is a market or a
Economic recovery is at least 6 12 months away.
the CapEx bubble has burst and we are likely to return to
spending only at 50% of the prior levels.
The ILECs and cable companies have free reign in the market.
Open Access in cable is dead.
A very interesting transition has occurred:
In the past the focus has been how to use voice
infrastructure for data; now the opposite is happening,
how to use data networks to carry voice.
This is putting pressure on the ILECs, who are dependent
on voice revenues, to examine how they will compete.
75% of the startup optical networking component companies
Seamless Wireless Networking
A bright spot at the conference is the emergence of wireless
In fact, the brass ring is for seamless wireless networking
has been stimulated by the success of 802.11b. That this technology has
been driven to commodity status much faster than anyone expected has been
a surprise. The existence of a standard, multiple chip set vendors, and
success in early enterprise deployments has fostered broader expectations
The most interesting talk was by Clark Dong, CEO, hereUare
They are seeking to be the solution provider for the creation of an ultra
high-speed global wireless network. The role hereUare is seeking is to
is the enabler for networks between the network owners such as Voicestream
and Wayport and the customer owners such as Go America. To accomplish
they offer enabling and interchange solutions. On the enabling side this
includes: access control, back office, tailored pricing products and
standards compliance. The interchange solution includes a framework for
standard contracts, roaming clearinghouse support and support for 3rd
party products. This is a network glue company that sees the increasing
opportunity to link cellular telephony with local broadband wireless.
Clark described their role as being the union of the conventional ISP
a cellular service operator. Another trend he felt that will grow with
increasing importance is the Mobile Virtual Network Operator (MVNO). This
operator will have strong local presence and potentially a lifestyle
brand, such as for teenage users. At the same time, he sees that the
industry will support multiple MVNOs in the same geographic area.
These concepts go well beyond what exists today. Clark Dong
as: the isolated network islands model and pure roaming clearinghouse
model. For the SWN network to exist the network deployment must grow,
there must be an underlying infrastructure to link the networks and there
needs to be a back office structure. hereUare Communications is seeking
play a role in making this happen between those that serve the public
those that run the networks.
We saw from a totally different perspective, approaches
supportive of this vision, from fabless semiconductor companies. At NGN
Ventures both Mobilian and Atheros presented their views of multi-standard
silicon. Atheros recently announced that it is sampling the first chip
that supports 802.11a/g/b. An interesting technology example was also
cited by Atheros. They have demonstrated, with Mercedes Benz, the ability
to download to a moving car using 802.11a. A use for this could be the
downloading of maps when the car enters a new town. On the chip side,
Mobilian described its TrueRadio, which is a systems level, on chip,
integration between Bluetooth and 802.11b to virtually eliminate
interference problems. It was also stated that the BOM for a complete
wireless solution must be <$35.
Stretching Technology and Services
The networking and telecommunications depression has turned
the market and
technology upside down. At NGN Ventures, we saw a number of innovative
approaches to leverage existing physical plants. Some of the emphasis
on multi-service offerings. For example, how can companies use IP-based
networks to provide traditional ILEC services such as ATM and FR? One
the reasons why this is important is that IP services typically cost much
less than switched services. If the IP networks can be used in other ways
it opens additional revenue streams and undercuts the ILECs. However,
is a carrier view and misses the point that an ISP can take. If there
multi-service offerings at Layer 3, which the ISPs normally interface
can this be used as a platform by the ISP to also offer new services?
however, the underlying network and OSS at the ISP must support these
services. Put in another way, the ISP begins to look like the combination
of an ISP + telecommunications carrier + cable MSO. Now the ISPs data
center takes on a whole new look.
The company addresses the seemingly ludicrous question:
over Copper. Using multiple existing copper pairs from 2 to 16 they are
able to deliver up to 100Mb/s on existing copper plant. Further, this
meets all the carrier requirements and standards and they claim five 9s
reliability. This approach goes after a soft spot the carriers have today:
It is too expensive to deploy new fiber;
There is a continuing demand for bandwidth and
There is a gap in digital service offerings from T-1 to T-3.
Thus a solution that works from 10 45Mb/s for virtually
any company or
individual with existing telephone wiring can have bandwidth well beyond
Actelis Networks uses what they call spatial division multiplexing
these rates. Other technical components include: CDMA across copper pairs,
FEC, and dynamic bandwidth management. They claim better than 10**-10
with distances up to 21,000 feet.
One might view this as DSL on steroids but the technology
goes well beyond
DSL. This is a company to watch because it provides a significant
performance improvement with marginal system costs.
This is another virtual fiber company but focused on the
cable plant. They
did not provide even top-level detail on the technology being used. What
was being suggested is that the cable plant, with adequate bandwidth using
their technology, can create a services computing model. It is here they
use Microsoft Windows as an analogy. Where Windows provides the essential
operating system for the WinTel platform they claim that the same analogy
applies to their Services Operating System, which links the
broadband network with the network services. Their software supports a
Broadband Bus, virtual memory in the form of scalable storage, and
inexpensive processing as part of the service control point. Integral
their network proposal is a SAN and residential gateway. With both
adequate intelligence in the gateway and storage in the SAN they can
support VoD, network based PVR, interactive games and on-demand storage.
It is not clear how the cable MSOs will greet such a proposal
but it is
certainly creative. What Narad Networks does is to completely reposition
not only broadband delivery, but the role of the home within the network
architecture. In this context the ISP takes on a whole new meaning in
servicing the Windows of cable.
Multi-Service Edge Products
MPLS is alive. We have been tracking this technology for
two years and it
appears to be getting serious. A problem with IP is that it is best effort
and virtually all past efforts at QoS have failed to gain market traction.
MPLS (Multi-Protocol Label Switching) is a means to assign a label to
aggregate stream of user data. This stream is then passed along a Label
Switch Path (LSP), which can provide priority for the stream based on
is assigned in the label. In order to work, the characteristics of the
data must be preserved up to the first router that supports a LSP and
take the data on the last router that supports LSP. That is, if the
routers at the core do not support MPLS it is ineffective. Thus, an
important component for implementation of MPLS are the edge routers, which
accept voice, video and traditional IP data. What was surprising at NGN
that there were four presentations of products that are either in
development, beta or shipping. It was also stated that there are 20
start-up companies in this space. MPLS is complex technology that has
winding its way through the IETF and it appears that MPLS is getting real.
The significance of MPLS is that it brings traditional switched
normally seen at Layer 2 to Layer 3, which is where ISPs interface to
network. MPLS also turns the networking market upside down because IP
service providers will be able to offer traditional telecommunications
services on a par with switched services but using the IP network. This
can be a direct threat to the ILECs. Further, it also opens up the ISPs
markets. This again has significant implications to the network
infrastructure present at the ISPs. The Data Center may come to look more
like a CO.
Equipe has a core platform that supports native ATM and
MPLS switching. It
supports up to 200Gb/s of data switching.
Laurel is targeting tier 1 service providers seeking to
offerings, using the ST2000 Service Edge Router.
TiMetra will announce its product in the fall. They are
focused on a
software-based MPLS router that is based on network processors.
Integral Access has a product called PurePacket, which is
describe this as helping create the new Internet, which has a core that
fully supports MPLS.
IP Networks Grow Up
In the sessions on NGN IP routers, Data Centers and OSS
it was impossible
to not see black and white. Enthusiastic companies presented innovative
technologies, especially those that make IP network carrier class, which
we call white and the black is who will place any orders for this?
and over the market disadvantage of the start-up companies was cited.
Given the end of the CLECs the only major buyers left are the ILECs and
is very difficult for start-up to make a sale to them. In session after
session these criteria stood out:
(1) The only equipment ILECs are buying, maybe, is that
has an assured ROI of less than a year;
(2) The equivalent of telecommunications products DOA comes
when they are associated with a back hoe (trenching) or fork
lift (replace a rack of gear); and
(3) Start-up companies with the best chance of winning are
those that keep the burn rate down, stretch cash and hold on
until 2004. It is not about innovation but the ability to
Yet, in spite of these contrasts we were impressed with
maturity of IP networking equipment. This not only will allow the Internet
to keep pace with the network growth but increase reliability, broaden
service offerings and lower costs. This is especially important for those
looking to build a new network or make a significant upgrade. Networking,
especially IP networking, is headed for a sea change and those buying
stand to gain much. It was stated that those who make investments in
todays environment in new technologies are the early adopters and
movers to gain market share.
Larry Roberts, the Chairman and CTO of Caspian Networks
gave a talk on
Next Generation Core Router Challenges. Larry did invent the Internet
predates any claims by Al Gore by roughly 30 years. Caspian is in trials
of its Aperio IP Switch which scales from 10Gb/s to 160+ Tb/s. Larry just
has this highly assured method of delivery that commands respect. If
anyone has been there it is Larry.
His talk began by describing how in the early days of the
ARPANet the view
was that packet routing should always be dumb and simple. This mind set
has been in place for 30 years and is now out of date. He cited the push
for MPLS but trashed the concept due to the politics of the IETF, which
has resulted in only a partial solution. Larry has done some studies based
on visits with many of the large IP carriers. He plotted how the demand
will outpace current routers. The router performance is also directly
correlated with Moores Law. Thus, he stated that now is the time
re-look at how IP is being used for routing in conjunction with the
intelligence of the switches. He claimed by using only the information
IP and making intelligent NGN routers it is possible to significantly
improve network performance and, in fact, support may of the proposals
within MPLS without the burden of the IETF standards process. Details
not given but the case made economically was quite compelling.
If these or some of the other NGN routers take hold in the
stands to significantly change the economics of long haul carriage,
including support for isochronous data as we discussed in an earlier
report on MPLS.
This is a part of the innovation surfacing to create the
NGN Data Center.
The premise of inkra Networks is that data centers are too hard to manage,
they do not scale well and fail to meet carrier class standards. His frame
of reference was the CO, this should be used as the role model for the
data center. If we took the opposite approach and used the data center
the central office the following would happen:
When you order voice mail a truck pulls up to install an
When you order a new phone line all the phones go down in the
When the telco gains a new customer they buy a new Class 5
inkras approach is not new but their implementation
is interesting. By
extending the CO view of the data center all of the major components
should be virtualized: network services, computers and storage. inkra
focused on the network sevices, which includes the routers. They claim
that both Sun and IBM are well along with computing virtualization and
EMC, Hitachi and Veritas are doing the same for storage. From this inkra
defines a conceptual unit in the data center called the virtual rack,
which includes each of the network services, processor and storage. These
racks can be dynamically managed and allocated to tasks. They claim that
this results in a highly available system that is fully redundant and
Surgient also advocated a virtualization of the data center
implemented their approach within the host OS. This layer between the
and the application allows for resource control to enable the
virtualization. They claimed this method works on Windows and Sun systems
but no details were provided.
I had discussions off line with others about the virtualization
This is one part of many shifts taking place in NGN data centers. Another
is the increased use of computer clusters similar to what DEC did with
VAX some 20 years ago. Clusters are becoming much more prevalent. Further,
the approaches to virtualization taken by both inkra and Surgient were
questioned. They have the shortfall that the management complexity has
been only increased by creating all these racks of discrete processors.
This can actually be worse, not better, compared to what exists today
a management standpoint. Another virtualization concept emulates one large
virtual data center. This is very similar to virtual memory where the
address space is very large and no one machine will ever use that much.
Each application would work in such a virtual machine and not be resource
limited. This is being done today with disk drives by EMC in data centers.
The advantage of this approach is that only one virtual element needs
managed rather than racks and racks. However, the implementation of this
with the disk system or SAN is straightforward, but in the processing
element if the native real OS does not support such virtualization it
would be hard to accomplish. However, this is what Surgient claims to
The intent of all of these proposals is to make the data
center like the
Class 5 switch. As one speaker stated this device has no on / off switch.
Downtime is measured in a few minutes per year. It never goes down when
new line cards are installed, it is repaired, components are replaced,
services added, or the box upgraded. For those that work with PCs such
laudable goal is highly desirable.
Lastly the ending session was on OSS the back office
software that makes
traditional ILECs operate. It includes functions of provisioning, billing,
activation and customer support. This is the mundane part of the telephone
and communications business, yet, if there was a bright star to meet the
ROI requirements, so that ILECs will buy, it is in OSS. One example cited
by CoManage is the problem of finding stranded resources. It was stated
that the database of physical assets and logical assets (communications
paths) are up to 40% to 60% inaccurate. A statement was made that if only
a 5% correction was made this could result in a $15B gain to the
Even here in the OSS we are beginning to see the development
of systems to
support IP networks. However, again the level of tools for IP networks
just does not match those that exist in conventional telephony.

***New SPECviewperf 7.0 Benchmark Traces
SPEC/GPC's OpenGL Performance Characterization (SPECopc)
today released SPECviewperf 7.0, a new version of its application-based
performance evaluation software. The new benchmark is available for free
downloading on SPEC's GPC News web site. Initial SPECviewperf 7.0 test
results from SPECopc members will be available on the site May 15.
SPECviewperf 7.0 includes new features for more accurately
graphics functionality from real applications. It provides new and
updated viewsets representing popular CAD/CAM/CAE and digital content
creation (DCC) applications.
SPECviewperf 7.0 enables general state changes to be made during frames,
bringing the benchmark much closer to how applications behave in the real
world. Data traversal, facet color processing, and display of lighting
and textures can now be changed from frame to frame.
The new viewsets have been designed to take advantage of
capabilities within SPECviewperf 7.0. The viewsets' frames are based on
traces of graphics commands made while running the actual applications.
As a result, vendors and users can tune their graphics subsystems to the
viewsets and see performance improvements in the actual applications.
Three new viewsets have been added based on traces of SPEC/GPC's
Application Performance Characterization Group (SPECapc) benchmarks:
-- 3dsmax-01, based on SPECapc for 3ds max 3.1 configured with the Open
driver, includes three models containing an average of 1.5 million
vertices each, and tests performance of scenes with different levels of
-- proe-01, based on SPECapc for Pro/ENGINEER 2000i2, measures two models
in three modes shaded, wireframe and hidden-line removal (HLR).
-- ugs-01, based on SPECapc for Unigraphics V17, tests performance based
on an engine model containing 2.1 million vertices.
The new viewsets replace three viewsets from SPECviewperf
6.1.2 that were
deemed obsolete: awadvs-04 was retired because frame rates commonly
exceeded refresh rates and it was based on an application that no longer
exists; medmcad-01 represented a mix of CAD/CAM functionality and didnt
focus on a specific application; and procdrs-03 was replaced because frame
rates commonly exceeded refresh rates and the test no longer reflected
Three long-time viewsets have been updated to run under
dx-07, based on the Data Explorer (DX) visualization application; drv-08,
based on the DesignReview model review application; and light-05, based
the Lightscape radiosity visualization application.
As a result of the major revisions and new viewsets, results
under SPECviewperf 7.0 cannot be compared with previously reported
SPECviewperf measures the 3D rendering performance of systems
under the OpenGL application programming interface (API). Viewsets are
the test files that run under SPECviewperf. They represent a similar mix
of graphics rendering and manipulation found in actual applications.
SPECopc is a project group of the Graphics Performance Characterization
(GPC) Group, which in turn is part of the Standard Performance Evaluation
Corp. (SPEC). SPEC is a non-profit corporation formed to establish,
maintain and endorse a standardized set of relevant benchmarks that can
applied to the newest generation of high-performance computers. SPEC's
membership includes computer hardware and software vendors, and leading
universities and research facilities worldwide.
0217.4 Cable Broadband
***CableLabs Publishes OCAP 2.0 Middleware Specifications
Cable Television Laboratories, Inc. (CableLabs) has extended
Application Platform (OCAP) software, or middleware, specification with
the release of OCAP 2.0. OCAP is a middleware specification that enables
application portability across home devices and cable networks. OCAP 1.0,
issued in January, defines a Java based Execution Engine (EE), and OCAP
2.0 extends that platform with the addition of web-based technologies
XHTML, XML, and ECMAScript.
The OCAP 2.0 specification is available to manufacturers,
developers, and the public through the OpenCable Web site
collection of specifications establishes
a road map for companies to create applications for interactive services
that operate over broadband cable networks.
Under OCAP, set-top boxes or integrated television receivers
would be able
to provide the same interactive services available on set-tops provided
the cable operator. CableLabs has worked through vendor comments on the
draft specifications over the past year and with that input, the
specification now has reached a build-to status.
These developments underscore the momentum that has been
support of OCAP. CableLabs has also secured commitments from several
supplier companies to provide on-site visiting engineers, off-site
contributing engineers, and general assistance in the further development
of the OpenCable Specifications, including OCAP. These suppliers include,
as of this writing, Alticast, Canal+ Technologies, Cisco, Liberate
Technologies, Microtune, Panasonic, Philips, and Sun Microsystems.
Several suppliers have made the additional contribution
of equipment to
CableLabs for use in the development and testing facilities for OCAP at
- Philips has contributed its "Silver Box" development
set-top box, which
supports test case and code development. Philips has also provided bit
streams that include video and embedded interactive application associated
with the video for the purpose of demonstrating MHP type applications
currently being planned for deployment in Europe this year. (MHP is the
European middleware standard which forms a substantial portion of the
spec work already done on MHP essentially furthers the completion
commercial OCAP-enabled boxes.) Philips has also provided a DVB-S QPSK
modulator to help convert the Silver Box for use on North American cable
- Thales has provided CableLabs with its Amber product for
video with data streams for server output of interactive services; its
Pearl product, that provides the capability to aggregate PSIP program
from multiple streams, and its Coral product, an object carousel or server
- S&T Technologies has agreed to provide an Object Carousel,
development software and sample interactive applications that may
potentially be migrated to OCAP.
- Sun will include CableLabs in their Media Appliance Early
Program, and loan to CableLabs their Sun Blade platform.
- Tektronix has agreed to provide a new DSM-CC analyzer
product, a key
piece of test equipment.
In other OCAP-related developments:
CableLabs has completed a first draft of documentation to
be provided to
its member companies and to headend equipment vendors to assist in the
proper design of networks that support OCAP. This initial draft includes
significant contributions by engineers from Cisco Systems and AT&T
Broadband. LG Electronics (parent company of Zenith) delivered its
development set top for interoperability testing at CableLabs in April.
LG and other Korean manufacturers are working on a fast track to build
OpenCable and OCAP-enabled devices for the Korean market where OpenCable
is a digital cable standard. (Digital cable is just now beginning to be
introduced in Korea.)
CableLabs continues to work closely with the DVB organization to keep
and MHP in alignment. CableLabs President and CEO Dr. Richard R.
as Chairman of ITU Study Group 9, also is active in harmonizing middleware
standards worldwide. CableLabs is also closely monitoring interim
standards efforts, such as TVXML or the iTV Standards effort, to assure
they proceed in harmony with OCAP.
CableLabs is a research and development consortium comprised
television system operators worldwide. CableLabs plans and funds research
and development projects that will help cable companies take advantage
future opportunities and meet future challenges in the cable television
industry. In addition, CableLabs acts as a clearinghouse to provide
information on current and prospective technological developments that
of interest to the cable industry.

***Butterfly and IBM to Introduce First Computing Grid for
Butterfly.net, Inc., a development studio and infrastructure
the online video game market, and IBM announced today the deployment of
the first-ever custom commercial grid for the online video gaming market.
The Butterfly Grid could enable online video game providers
to support a
high number of players within the same game by allocating computing
resources to the most populated areas and most popular games.
The Grid was built by Butterfly.net over the last two years
e-business infrastructure technology that distributes the processing of
video game interaction across a network of server farms. The Grid is a
secure system built on customized software operating on the private
network of Butterfly.net.
Video game providers can access the Grid to support their
by including the Butterfly Grid client software libraries in the games
they distribute. These software libraries, along with sample code for
connecting mobile devices, PCs and video game consoles to the Grid, are
available for download from www.butterfly.net.
The Butterfly Grid is powered by rack-mounted Linux-based
xSeries systems hosted by IBM and running on internal fiber-optic
networks. The grid design offers the potential to support over one million
simultaneous players from each facility in a 24/7 environment with
automatic fail over capability.
Online video games have historically segmented players onto
servers, limiting the number that could interact and creating reliability
and support obstacles. When one server is down, or patches are being
installed, game-play comes to a halt. Butterfly's grid technology enables
online video game providers to deliver games to millions at the same time.
The server interaction is completely transparent and seamless to the user
- delivering a resilient gaming infrastructure where servers can be added,
or replaced, without interrupting game-play.
The new Butterfly Grid is the industry's first to provide
- Massive numbers of players within one persistent-state
- Before the Butterfly Grid, online video games have been
"shards" that provide copies of the game world on separate servers,
limiting the number of players that can interact. The Butterfly Grid
provides "cross-server sentinels" that could potentially support
interaction of millions of players in one true world, with server
boundaries invisible to players.
- Distributed Artificial Intelligence - Butterfly.net provides
controller" for interactions between players and non-player characters
through a standard Python interface.
- Multiple, concurrent games - With multiple online video
games on one
computing grid, publishers can allocate resources to more popular games,
launch new games with less risk, and offer flexible and innovative
subscription plans to drive revenue growth.
- Connected devices - Butterfly.net connects PCs, PocketPCs,
Palm-compatible handhelds, and dedicated video-game consoles in
multiplayer online games. A packet-transport protocol provides balanced
game-play over broadband, dial-up and mobile Internet connections for
- Hot-swappable components. - With the grid architecture,
once an online
video game is launched, it doesn't need to be taken off line for patches
or maintenance. When grid components are unavailable, connections are
redirected to available resources for continuous game play.
- 3D engine support - Game developers working on the Butterfly
exploit fully integrated, industry-standard 3D engines out of the box.
- Shared-source developer sandbox.- License program allows
prototyping on live server grid with full bandwidth and simulation/load
An emerging model of computing, Grids are built with clusters
joined together over the Internet, using protocols provided by the Globus
open source community and other open technologies, including Linux, to
create and manage virtual computing resources. Grid protocols emerging
from the Globus open source community are enabling organizations to create
virtual organizations sharing applications, data and computing power over
Butterfly.net is working with Globus to ensure that any
developed according to publicly-available specifications and Internet
standards can draw resources-on-demand from the Butterfly Grid. The Globus
Toolkit, available by download from www.globus.org, provides authorization
and accounting functions, allocates hardware resources, configures
game-specific logic and monitors performance on the Butterfly Grid.
Butterfly.net will demonstrate the Butterfly Grid system
to members of the
video gaming industry at the Electronic Entertainment Expo (E3) 2002 show
beginning May 21 in Los Angeles.
