Performance under a failure of wide-area datagram networks with unicast and multicast traffic routing

Abstract

A major link or node failure in a network can severely affect services offered by the network. In this paper; we address network perfomnce, especially, in the event of a link failure in the presence of both unicast and multicast muting in wide-area datagram networks, such as the Intemet. Since various services can exert different workloads (per connectiodsession), we have developed workloads to reflect both one-to-many and many-to-many multicast communications on top of multicast routing. Through network simulation, we quantify effects on how unicast services and multicast services are affected due to such a failure.

COSMOS: Multi-Layered Network Survivability Project

“…Several graduate students have been involved in development of MoMaRS simulation tools. Before the project started, Samir Shah started working on the first enhancement to MaRS [3] to consider the multicast shortest path routing component [27]. Then, Gerald Rogers initiated the development of the MKompella multicast routing algorithm and priority-based routing to consider differentiated services environment (reported in his MS thesis [24]; also, see [25]); Suresh Muppala added the RSVPcomponent to this tool [18] while Ulka Ranadive added the TCP component as well as HTTP workload to this tool [21,22].…”
