Collaborative Video Conferencing Services over Internet2 Initiative

Provide a service that is intended to enable one-to-one, one-to-group, and group-to-group collaborative conferencing in support of personal communication, meetings, conferences, and shared education for Internet2 members (primary and sponsored) and their international counterparts.

Basic Tenets of Service

•Independent of geographic or national boundaries

•Video conferencing viewed as current best collaborative environment

•Gateways between technologies will be necessary

•Gateways must be transparent to end users

•Need to consider voice/telephony integration

Key Technical Issues

•A Global Dialing Plan

•A Global Directory Service

•A Scheduling Mechanism for the use of shared resources

•Improvements and coordination in “back room” functionality and control

•Interoperability with other significant communication services (gateways)

Key Technical Issues (Continued)

•QoS

•Multicast

•H.235 Security• Authentication• Authorization• Privacy• Non-Repudiation

Collaborative Video Conferencing Services over Internet2

Proposed Prototype Service

•Focus on deployment not research

•Start with single technology

•Recommended that that prototype service be based on H.323 technology

•Based on contributed resources

•Based on distributed management

•Based on distributed systems

•Emphasis on Gateways (centralized if necessary)
