4. Real Time Communications Advisory Group4 Charter - Deliverables A technology/application architecture with a roadmap of what is available today and what is visible on the horizon, including identification of key standards that are necessary for interoperability of real time communications applications; Recommendations for production, Internet2-wide and beyond, implementations of RTC tools and applications that integrate with work on middleware and include end-to-end diagnostics and support mechanisms; A guide to RTC applications that will help members understand which of the applications or approaches may best fit their needs and information on how to best deploy them for different purposes in our community; A recommendation on how best to align the production service, research and development activities now going on within Internet2. The result should be an alignment of working groups and a set of prioritized activities

6. Real Time Communications Advisory Group6 Deployment Goals Massive deployment Part of campus expectations? Implements reference architecture Standardized external campus interfaces To talk to any campus, use these well documented interfaces Standardized internal components Allow flexible internal deployment, but expect that campuses will be similar and will draw from the same tool sets and best practices

7. Real Time Communications Advisory Group7 RTC Priorities: Operational Sharing of deployment experiences related to the reference architecture Promoting deployment of reference architectures Enabling very large scale RTC network availability Facilitating campus interoperability Creating a market for Corporate Member Work Products Publishing and Outreach

8. Real Time Communications Advisory Group8 RTC Priorities: Research and Development Security and Identity Management Location Services Disaster Recover Next Generation Protocols Mobility

9. Real Time Communications Advisory Group9 Deprecated Activities Numeric Addressing This is controversial with competing needs. Wait and see. Sharing of Trunks and Gateways for Toll Bypass Simply an operational issue. Not strategic DO support this for disaster recovery

10. Real Time Communications Advisory Group10 Background: Problems Overlapping Activities and Mixed Messages to the Membership Addressing 911 and Presence Directory Services Varying degrees of WG activity from dormant to hyper Confusion of Message to Corporate Members RTC emerging as a critical application

11. Real Time Communications Advisory Group11 Creation of a Standing RTC Steering Committee a la MACE Manage the creation, development and closure of RTC working groups. Support the harmonization of technical activities across the various RTC working groups to promote consistency of direction and re-use of work products. Facilitate communication among the various RTC working groups to ensure that diverse perspectives are well understood within the more narrow activities of specific RTC working groups. Advise Internet2 with regard to resource allocation for RTC-related activities and projects. Maintain an overarching architectural vision for RTC that is inclusive of the breadth of RTC-related activities, addresses near term needs of the membership, and promotes an aggressive and forward looking vision of the RTC application space. Promote Internet2 RTC activities within the membership and to the public. Act as a focal point for communications with Corporate Members, vendors and the development community in order to maintain a consistent message about development direction.

12. Real Time Communications Advisory Group12 Working Group Alignment Recommendations Presence and Instant Communications (PIC) Keep Voice Over IP Working Group (VoIP-WG) Change to RTP-VoIP-SIG RTC Middleware Working Group New working group Data Collaboration Working Group New working group SIP.edu Migrate into established new structure and expand I2 Instant Messaging (I2IM) Close. Move to PIC Video Middleware (VidMid-VC) Close. Move to RTC-Middleware ITEC Under discussion Commons (not a working group) Continue and expand to complement RTC

13. Real Time Communications Advisory Group13 Working Group Structure RTC- DataCollab RTC- Middleware RTC- PIC RTC- VoIP-SIG Communications - Internet2 - Membership - Developers RTC-SC VoIP-WG SIP.edu I2IMVidMid-VC Common Reference Architecture

14. Real Time Communications Advisory Group14 RTC-DataCollab Problems Few Standards Exist Campus Investment in Data Collaboration Tools is Very High Content Lock New WG: RTC-DataCollab Seed / matching funding from Internet2 Matching funding from participants (skin) Call for participation to CIO and technologists key to potential success and buy in Caution: History of entropic efforts. Proceed with commitment, else wait.

15. Real Time Communications Advisory Group15 Discussion How best to expand SIP.edu to: Massive deployment? Media rich environment, not VoIP? Include more components of the reference architecture?

16. Real Time Communications Advisory Group16 Discussion What should be the scope and mission for RTC-DataCollab?
