Satellite links have wide area coverage and are used for international backbone links. Asian Internet Interconnection Initiatives (AI3) Project is one of the most operational satellite based R & D network in Southeast Asia. IP multicast is the important technology for the future Internet. Broadcast capability of the satellite link is suitable for the IP multicast application. Uni Directional Link Routing (UDLR) technology is one of the solutions to provide multicast routing for Uni Directional satellite link. This paper introduces the UDLR technology which can use UDL satellite link as the Internet infrastructure, discusses the way to provide wide area IP multicast using UDLR technology, and describes the evaluation on the AI3 project. Also, this paper describes the actual application on the AI3 multicast network, such as web cache distribution and distance learning.
