Abstract [en]

Group collaboration and media distribution ap- plications have attracted more interest during recent years. With an increasing attention to wireless environments and business applications there is a growing need for reliable multicast communication protocols. There have been mainly two approaches, proactive or re- active, to error handling in reliable multicast. Proactive protocols transmit redundant information along with the original information, enabling the receivers to repair lost packets without the necessity of feedback to the sender. Re- active protocols rely either on positive or negative feedback from the receivers. A case of special interest in relation to wireless connec- tivity is where essentially one receiver on a lossy link even- tually will consume most of the error handling resources. This problem has been addressed by some researchers, e.g. by the use of probabilistic methods. We propose to view reliable multicast as a special case of semantically reliable multicast. We propose to make use of the application’s knowledge of its specific semantics to improve e.g. on the problem with single, lossy, links. We suggest the design of a semantic rule set for the transport layer protocol, which can be configured by the application. Using application semantics would allow the application to relax the reliability requirement at the transport level.
