Incremental deployment of a new network service or protocol is typically a hard problem, especially when it has to be deployed at the routers. First, an incrementally deployable version of the protocol may be needed. Second, a systematic study of the ...

Many problems with today's Internet routing infrastructure--slow BGP convergence times exacerbated by timer-based route scanners, the difficulty of evaluating new protocols--are not architectural or protocol problems, but software problems. Router software ...

One approach to achieving scalability in reliable multicast is to use a hierarchy. A hierarchy can be established at the application level, or by using router-assist. With router-assist we have more fine-grain control over the placement of error-recovery ...

Multicast routing enables efficient data distribution to multiple recipients. However, existing work has concentrated on extending single-domain techniques to wide-area networks, rather than providing mechanisms to realize inter-domain multicast on a ...
