4. u VRVS is a realtime distributed system which provides a scalable communication infrastructure for large collaboration dispersed all over the world. u Different technologies and protocols are supported (and mixed) and allow users to connect their preferred videoconference. u Supports Mbone, H.323, SIP, QuickTime, Access Grid, JMF and MPEG2. u The system is composed of 1 main server and several reflectors (network servers) spread around the world. VRVS: What it is ?

5. u Unified Web User Interface to schedule and join/leave a meeting independently of the application. u Multi-platform: Windows, Linux, MacOS and Unix. u Easy to use: Everybody knows how to click on a web page today. u Virtual Room Concept, Scheduling; Create a virtual space were people can exchange real-time information. u Join or Leave a Collaborative session anytime. Do not need to know in advance how many participants and booked ports capacity. Just announce the meeting and people will join from anywhere. u Full Documentation and Tutorial u Self service: Don’t need a technician or expert to organize and join a conference.

11. 11 Main critical RTC issues: Manageability Reliability Scalability Security Functionality / Usability From VRVS To EVO: End-to-End Self Managed RTC Infrastructure Developing/Deploying a Very Robust and Scalable Real-Time Collaborative (RTC) Infrastructure is a real problem that no- one was able to fix yet !

12. 12 What’s wrong ? Why can we not achieve total reliability/robustness when deploying a RTC Infrastructure ? From VRVS To EVO: End-to-End Self Managed RTC Infrastructure  The Real-Time Collaborative environment is a living environment, constantly changing, evolving. In addition devices/domains/nodes are managing by several independent technical and administrative entities

13. 13 By creating a “living” RTC Infrastructure capable to react/adapt to the change of the environment in real-time transparently to the end-user Solutions ?

14. 14 Building a Scalable RTC Infrastructure Multicast Network: It is not any more a global solutionMulticast Network: It is not any more a global solution –After more than 10 years of development/deployment, It reaches its maximum level of reliability/robustness –It is just a transport mechanism No QoSNo QoS No awareness of the Application levelNo awareness of the Application level No data processing as required by the some application (mixing audio, select video streams, ….)No data processing as required by the some application (mixing audio, select video streams, ….) –Extremely difficult to troubleshot because it crosses several administrative domains Today’s solution: Building an Overlay Network by deploying intelligent Software Agents communicating using Unicast connections and capable of using Multicast transport when it makes more sense
