The State of Indiana High Speed Network Presented by Edward J. Tully Director of Systems Operations Indiana Higher Education Telecommunication System

Agenda Indiana and high speed networking –Where we began –Where we are today –Development and deployment strategies –Architectural development Challenges and solutions

The High Speed Backbone Pre-February 1998 –Operated, managed by IHETS, owned by and accessible only to public and private higher education institutions in Indiana –13 router nodes statewide, all located on university campuses –TDM (fractional DS3)/IP based –Basically provided Internet access

The High Speed Backbone Post-February 1998 –Operated and managed by higher education (IHETS); overall project management by Intelenet Commission (a state agency) and accessible to all tax supported entities in Indiana K12, libraries, state and local government agencies

The High Speed Backbone Post-February 1998 –10 ATM switch/router nodes statewide, all located in AT&T POPs –TDM DS3/ATM-based –Provides Internet and Intranet access –Offers data, video and voice services statewide

The High Speed Backbone Post-February 1998 –Offers a multitude of network-centric services Videocaching & videocasting DNS and services Audio/video bridging services Video gateway services for 3.3Mbps compressed satellite video and 45Mbps terrestrial services ISDN gateway/video bridging services

Network Development Exponential growth in the use of technology by public sector Private sector networking unavailable No one could afford to “go it alone” Formed a “consortium” to pool resources

Development Strategy Initial Strategy –Develop a new infrastructure ( ) abandoned: too costly, unreasonable timeline –Entice the private sector ( ) failed: No funding, no commitments for utilization

Development Strategy Adopted Strategy –Leverage existing resources ( ) only existing statewide resource: INDnet - the IHETS network serving all public and private higher education institutions in Indiana INDnet became the infrastructure to serve all of the public sector in Indiana

Deployment Strategy Initial Strategy: Backbone –INDnet ( ) IP-based network –Router-based nodes located on college campuses IP not ready to deal with voice and video –ATM to be used on the backbone

Deployment Strategy Initial Strategy: Access Network –ATM in the access network with the use of voice and/or video. Video deployment as H.321 Standard Voice deployment limited and proprietary –Constantly monitor the development of IP technology for voice and/or video

Deployment Strategy Current Strategy –ATM in the backbone network & the Access Network –IP video (H323) deployable in point-to-point as well as in multiparty conference –Gateway capability between H.321 and H.323 available

New Challenges High speed access development with 44 local telco’s vs. continued use of dedicated point-to-point service offerings –Idea accepted by Ameritech, GTE and a few smaller local telco’s –ATM, DSL, cable Exponential increase in the use of bandwidth
