A huge number of application scenarios would greatly benefit from a group communication service in the Internet, but the existing IP Multicast solution still lacks global availability due to several technical and political issues. As a consequence, Application-Layer Multicast (ALM) arose as a promising solution to overcome this missing global multicast deployment. In ALM, forwarding functionality and membership state is exclusively handled on the participating end systems, following the well-known peer-to-peer paradigm. A typical ALM node has to handle higher traffic load than compared with native IP Multicast because packets are duplicated and forwarded on the nodes rather than in infrastructure routers.
