Middleware Challenges
Identify technologies that are scalable and interoperable
Increase deployment of middleware technologies as part of a pre-commercial production environment
Examples:• Distributed storage - I2DSI initiative• Multicast video tools - I2DVN initiative
Deploy a production network to support applications R&D
Establish quality of service (QoS)
•Qbone initiative 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
Fall 1998: Demonstrated network at member meeting, in pre-production at several universities, connected to Chicago switch for STAR TAP
Janurary 1999: Initial set of members connected in production mode
By December 1999: around 65 institutions connected
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) Programhttp://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 RelationshipInternet2 <--> 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
Internet2 International Collaborations
Building peer to peer relationships Looking for similar goals/objectives and
similar constituencies Mechanism: Memoranda of Understanding Signed: CANARIE, Stichting SURF,
NORDUnet In process: TERENA, SingAREN, JAIRC,
APAN and others
What kind of collaborations?
Network interconnection• Abilene and CA*net2, SURFnet, NORDUnet,
etc. Specific project collaboration
• QBone• middleware• research/learning applications
Technology transfer• mutual industrial participants?
Information exchange
International task force• to advise our Board, management on
issues of international collaborations Greater participation in international
groups• CCIRN• GIBN
