17. 2000 COVANET - frame relay, ATM and other high speed services Establishment of COTS Voice over IP Workgroup with pilot projects Pilot project for digital signatures

18. Network Development - 2000 Network Virginia Virginia – I2 Architecture Internet2 ESnet SprintLink IP Available Statewide Supports Data, Video, and Voice – H.323 Supports QoS Available 3 rd Qtr, 2000 Flat Rate Distance Insensitive Usage Insensitive NIH NLM COVANET Other ISPs

19. Network Development - 2000 More bandwidth – –Gigabit scale backbone network –More than 16 times the capacity of the current backbone Advanced IP services –IP-based Quality of Service (for video, voice over IP) –Native multicast More expansive acceptable use policy –Requirement for extending access to I2 to K-12, etc.

20. Next Generation Infrastructure for Virginia Internet Internet 1 Internet Internet 2 Extremely High Performance Access to Internet 1 and Internet 2 MNAP Gigabit Capacity Statewide OC48c, 2.5 Gbps, WDM Channels Initially 16 times the capacity of the Net.Work.Virginia Backbone Public / Private Partnership for Rapid Deployment to All Sectors Packet Switched Core with Advanced IP Features Support for QoS, Multicast New modes for multimedia, e-commerce, entertainment, education

21. Future 2001 - 2003 Enhance statewide high speed infrastructure merging voice, data and video Compete all local telephone services Increased bandwidth facilities to all private and public entities in VA Wireless voice & data expansion for mobile workforce Digital Signatures for e-commerce Strengthen partnership between research and operationsStrengthen partnership between research and operations
