In this survey article we describe the roots of IP Multicast in the Internet, the evolution of the Internet Multicast Backbone or "MBone," and the technologies that have risen around the MBone to support large-scale Internet-based multimedia conferencing. We develop the technical rationale for the design decisions that underly the MBone tools, describe the evolution of this work from early prototypes into Internet standards, and outline the open challenges that remain and must be overcome to realize a ubiquitous multicast infrastructure. We and others in the MBone research community have implemented our protocols and methods in "real" applications and have deployed a fully operational system on a very large scale over the MBone. This infrastructure --- including our audio, video, shared whiteboard tools and protocols --- is now in daily use by the large and growing MBone user and research communities and the success and utility of this approach has resulted in commercialization of many of the underlying technologies.
