In this talk I will present a set of techniques used for End-System Stream Multicast -- specifically those proposed by Jin, Sharma, Bestavros, and Matta (see references below). These techniques were inspired/influenced by the Skyscraper approach proposed by Hua et al. I will contrast cache-and-relay versus prefetch-and-relay, whereby in the former end-systems cache played-back content as opposed to prefetch future content in the stream.

This Paper presnet the Skyscraper approach which is the base for the work we present.

This paper overviews the basic "Cache and Relay" approach and presents
analytical results regarding its scalability.

This paper presents the implementation details of Cache and Relay

Prefetching Protocol for Scalable Asynchronous Multicast in P2P Systems.
In Proceedings of Infocom'05.

This paper considers the effects of churn on cache and relay systems,
and proposes the use of prefetching as a better technique. It provides
evidence of the scalability of this technique even in the presence of
