Abstract(published online Nov. 2, 2004) Multicasting at the IP layer has not been widely adopted due to a combination of technical and non-technicalissues. End-system multicast (also called application-layer multicast) is an attractive alternative to IP layermulticast for reasons of user management (set-up and control) and attack avoidance. Sessions can be establishedon demand such that there are no static points of failure to target in advance.In end-system multicast, an overlay network is built on top of available network services and packets aremulticasted at the application layer. The overlay is organized such that each end host participating in a multicastcommunication re-sendsmulticasted messages to some of its peers, but not all of them. Thus end-system multicastallows users to manage multicast sessions under varying network conditions without being dependent on specificnetwork conditions or specific network equipment maintaining multicast state information.In this paper we describe a variety of proposed end-system multicast solutions and classify them according tocharacteristics such as overlay building technique, management, and scalability. Comparing these characteristicsacross different end-system multicast solutions is a step toward understanding which solutions are appropriatefor different battlespace requirements and where further research is needed.
