Abstract

The need to support multicast (or multipoint) communication in the Internet has been recognized for a long time. Significant effort has been expended over the last three decades by networking researchers and practitioners in designing and building multicast support capability within the Internet. In addition, several research efforts have demonstrated that highly scalable and desirable multimedia and information services can be deployed on top of a multicast-capable Internet infrastructure. Despite this, wide-spread availability and use of multicast communication is lacking in the Internet today. In this talk I will consider the history of multicast communication and services. This will be done in the context of an evolutionary model that explains the current state of multicast deployment. This exploration allows us to draw some lessons regarding the evolution of the Internet and how our approach to research and deployment can affect this evolution.
