— We present a novel congestion control algorithm suitable for use with cumulative, layered data streams in the MBone. Our algorithm behaves similarly to TCP congestion control algorithms, and shares band-width fairly with other instances of the protocol and with TCP flows. It is entirely receiver driven and requires no per-receiver status at the sender, in(More)
In this paper we present a Reliable Multicast data Distribution Protocols (RMDP), and discuss its performance. The protocol is based on the use of FEC techniques to drastically reduce the impact of independent losses for different receivers, which make ARQ-based protocols perform very poorly as the number of receivers grows. The protocol is well-suited to(More)
In this paper we analyze Web access traces to a proxy, in order to derive useful information for the development of a good replacement policy for documents held in the cache. The analysis reveals a number of interesting properties on the lifetime and statistics of access to documents, which are discussed in this paper. These properties show why LRU works(More)
Applications requiring the reliable distribution of data to groups of clients would be supported perfectly by reliable multicast protocols. In many cases, the problem of congestion control (a major research issue otherwise) does not exist because downlink bandwidth is \owned" or can be preallo-cated to a particular server by independent means, but the(More)
