From VRVS To EVO: An End-to-End Self Managed RTC InfrastructureOutlines

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

Unified Web User Interface to schedule and join/leave a meeting independently of the application. Multi-platform: Windows, Linux, MacOS and Unix.Easy to use: Everybody knows how to click on a web page today. Virtual Room Concept, Scheduling; Create a virtual space were people can exchange real-time information.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.Full Documentation and TutorialSelf service: Dont need a technician or expert to organize and join a conference.VRVS Web Service Design

Whats Next ?

Main critical RTC issues:

Manageability Reliability Scalability Security Functionality / UsabilityFrom VRVS To EVO: End-to-End Self Managed RTC InfrastructureDeveloping/Deploying a Very Robust and Scalable Real-Time Collaborative (RTC) Infrastructure is a real problem that no-one was able to fix yet !

Whats 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

By creating a living RTC Infrastructure capable to react/adapt to the change of the environment in real-time transparently to the end-userSolutions ?

Building a Scalable RTC Infrastructure

Multicast Network: It is not any more a global solution After more than 10 years of development/deployment, It reaches its maximum level of reliability/robustnessIt is just a transport mechanismNo QoSNo awareness of the Application levelNo data processing as required by the some application (mixing audio, select video streams, .)Extremely difficult to troubleshot because it crosses several administrative domains

Todays 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
