MTCP: scalable TCP-like congestion control for reliable multicast

摘要

We present MTCP, a congestion control scheme for large-scale reliable multicast. Congestion control for reliable multicast is important, because of its wide applications in multimedia and collaborative computing, yet non-trivial, because of the potentially large number of receivers involved. Many schemes have been proposed to handle the recovery of lost packets in a scalable manner, but there is little work on the design and implementation of congestion control schemes for reliable multicast. We propose new technique that can effectively handle instances of congestion occurring simultaneously at various parts of a multicast tree.
