19th APAN Meeting Bangkok, Thailand January 2005 Secure real-time audio/video communication – H.350, Encryption & Gatekeeper/Proxy – using H.323 (…and a bit SIP) Tutorial/Workshop Session - The future of H.323 – Are H.323 and SIP merging? - 19th APAN Meeting Bangkok, Thailand January 2005

Outline What else do we have? What else could merge? H.323 vs. AccessGrid? H.323 vs. VRVS? H.323 vs. Telesuite? H.323 vs. SIP? What do we want/get in the future?

What else do we have? What else could merge? H.323 vs. AccessGrid http://www.accessgrid.org multicast based; based on MBone tools (VIC/RAT) High demand of computing power (3 PCs, one for video, one audio, one data) Some H.323 – AccessGrid Gateways are in place Look to Stephen??? Unlikely (my personal option) that H.323 and AccessGrid will merge → too different AccessGrid node UC Berkeley

What else do we have? What else could merge? H.323 vs. VRVS http://www.vrvs.org Nice room based booking system based on MBone tools Gateway in place, but quality is rather bad, <10fps, etc. Unlikely that H.323 and VRVS will merge → too different

What else do we have? What else could merge? H.323 vs. Telesuite http://www.telesuite.com “Scotty beam me up” Great looking VC system You get the feeling of Cpt. Picard on the Enterprise What standard are they using? Propriety? (Very) Unlikely that H.323 and Telesuite merge

What else do we have? What else could merge? H.323 and SIP It is likely that both standards will merge in 3 to 5 years (my prediction) Both standard have a lot in common, except the singalling is different (there are some more differences but in general only the signalling is different) Audio/Video streams are both udp based rtp streams They already work together in several MCUs Some vendors have both stacks in their machines Both standards will live next to each other for the next couple of years with some bridging they work together…

What do we want/get in the future?
