This chapter explains related works to this book in detail. Section 2.1 reviews the evolution of IP multicast. The working principles of classic intra- and inter-domain IP multicast mechanisms are described. IP multicast has the scalability issue, which stimulates the research on overlay multicast. Section 2.2 presents main approaches to implement overlay multicast. Overlay multicast is implemented at the application layer, but the network layer knowledge is still needed for bandwidth efficiency. Section 2.3 introduces some representative multicast mechanisms proposed recently. The feature they have in common is to enhance network routers with more intelligence. This methodology is termed as application-oriented networking (AON). Section 2.4 explains the concept of AON in detail. Section 2.5 introduces an application of multicast mechanism, IPTV. The IPTV definition, architecture, and a specific technique issue, channel zapping, are discussed. This chapter is summarized in Sect. 2.6.
