Abstract :
Since 1993, we have been involved in the development and deployment of network architecture and protocols for distance learning. The first platform was based on ISDN and H.320 protocols. Now, we implement, test and validate a new Internet based architecture. We present an Internet based platform for e-learning and discuss some of issues concerning accessibility and mobility. To deal with these issues, we propose to integrate SIP into this platform. This integration provides easy support for mobility, service "customization", access simplicity, etc., as well as a rapid development and deployment of new services. After a description of the different connection scenarios using SIP, we focus on testing and measuring performances, mainly in terms of service establishment delays. Analysis of results shows that, for low bit rate link access (modem) and wireless (802.11b) access, performance needs to be improved.
