Without doubt, multicast communication as a means for one-to-many or many-to-many delivery of data has become a hot topic in multimedia environments. A lot of people are interested in multicast: the research community, standards groups and Internet Service Providers (ISP) among them. Although IP multicast is a very good solution for Internetworking multimedia in many-to-many communications, there are still issues that have not been completely solved. Protocols are still evolving and new protocols are constantly coming up to solve these issues because that is the only way for making multicast become a true Internet service. The main goal of this chapter is to describe the evolution of IP multicast from the obsolete MBone (Multicast Backbone) and intra-domain multicast routing to the actual inter-domain multicast routing scheme. We will pay special attention to the challenges and problems that need to be solved, the problems that have been solved and the way they were solved. We will make a complete picture of the state of the art explaining the idea behind each protocol and how all those protocols work together.
