Middleware Challenges
Identify technologies that are
scalable and interoperable
Increase deployment of middleware
technologies as part of a precommercial production environment
Examples:
• Distributed storage - I2DSI initiative
• Multicast video tools - I2DVN initiative
Engineering Objectives
Deploy a production network to
support applications R&D
Establish quality of service (QoS)
Support native multicast
Establish gigaPoPs as effective
service points

Abilene Characteristics
2.4 Gbps (OC48) among gigaPoPs,
increasing to 9.6 Gbps (OC192)
Connections at 622 Mbps (OC12) or
155 Mbps (OC3)
IP over Sonet technology
Access PoPs very close to almost all
of the anticipated university
gigaPoPs
Abilene Schedule - the latest
Fall 1998: Demonstrated network at
member meeting, in pre-production
at several universities, connected to
Chicago switch for STAR TAP
January 1999: Initial group of around
65 members connected in production
mode
1999: Other members connected as
mutually planned
For UCAID Members
Involvement in the decisions
Responsive to continuing needs
Driven by member research
Potential for increasing connectivity
for all UCAID university members
wanting to participate in Research
Goals.
Current Priorities
Establish backbone connectivity
Facilitate middleware implementation
Support network research
Identify and develop first phase
applications
Build international collaboration
opportunities
US Federal Government:
Next Generation Internet (NGI) Program
http://www.ngi.gov
Established in parallel with Internet2
multi-agency research and development
(R&D) program to develop, test, and
demonstrate advanced networking
technologies and applications
via testbeds that are 100 to 1,000 times
faster end-to-end than today's Internet
Internet2 <--> NGI Relationship
Similar technical objectives
Focused on different, but complementary
communities
• NGI: Federal Mission agencies
• UCAID/Internet2: university research and education
community
Working to interconnect, make
interoperable federal research networks
and Abilene
Internet2 <--> NGI Relationship
cont’d
Cooperative programs:
• NSF High Performance Connections grants:
UCAID universities using to connect to achieve
Internet2 connectivity
• Abilene <-> Energy, NASA network
interconnection: being planned to provide high
performance access for universities to research
labs
• Applications: researchers benefit from numerous
federal grants that help develop applications
The QBone - What is It?
An interdomain testbed for differentiated
services
Goals:
•
•
•
•
