What is Source Discovery

Chapter 23
Encyclopedia of Internet Technologies and Applications
This problem arises when a host sends a join message to a router. The router can forward this join message toward the source of the multicast group if it has information about the source. This problem is more difficult, if the joining host and the source of the group are in different ASs (see above). In this situation, the MSDP (see above) can be used in order to exchange the information about the active sources among the ASs.

Abstract
Despite the efficiency of the IP-multicast it has not been deployed in the whole Internet. The main reason is that the wide-area multicasting among the different autonomous systems (AS) has not been solved perfectly. The global address allocation is especially a problematic part of Internet-wide multicasting. This article addresses such problems in order to review the existing methods and the emerging research results (Hosszú, 2005).
