Deployment Issues
Auerbach Publications eBooks · 2005
IP multicast offers the scalable point-to-multipoint delivery necessary for using group communication applications on the Internet. However, the IP multicast service has seen slow commercial deployment by lSPs and carriers. The original service model was designed without a clear understanding of commercial requirements or a robust implementation strate y The very limited number of applications and the complexity of the architecturaydesign -which we believe is a conse uence of the open service model - have deterred widespread deployment as wej. We examine the issues that have limited the commercial deploymeni of IP multicast from the viewpoint of carriers. We analyze where the model fails and what it does not offer, and we discuss requirements for successful deployment of multicast services.
