ICT-09-12 A thesis submitted in partial fulfillment of the re quirements for the degree of Master of Engineering in Information and Communication Technologies, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 2009 Digital Video (DV) is a standard by International Electrotechnical Commission (IEC) for high quality video and audio formats. DVTS is a technology that uses DV standards to send DV streams as unicast or multicast over Internet. Dvrelays are used to relay streams between different networks where they behave as gateways to accommodate the different properties of the networks. These Dvrelays themselves form a kind of overlay network on the underlying heterogeneous network. Conducting online seminars among members of a multicast group with DVTS and Dvrelay is still a difficult task even within a small member group with a few senders as all Dvrelays must be manually configured. In this thesis, we propose to have a system which automatically configures all the Dvrelay nodes in the DV delivery overlay network to serve online talks or seminars according to the given agenda. The approach being proposed here is to design and implement an overlay system using Dvrelay installed gateways with a centralized controller server for the seminar which distributes the agenda file to all the members and take care of the overall operation of online seminar. Dvrelay gateways on the overlay network exchanges their connected link information among neighbors and finally ended up with an identical topology table of overlay at each gateway. After receiving the seminar agenda from the centralized server, gateways now can build the shortest path tree from sender to receivers and can start sending DV stream according to agenda by enabling Dvrelay as required.
