The promise of a buffered crossbar switch - a crossbar switch with a packet buffer at each crosspoint - is that it can provide good delay performance with much less complex, practical scheduling algorithms. With today's technology, it is now possible to implement it in a single chip. Thus it has attracted great attention recently. Though simple distributed algorithms can achieve 100% throughput under...
The problem of providing quality-of-service (QoS) guarantees for multicast traffic over crossbar switches has received limited attention despite the popularity of its counterpart for unicast traffic. Providing a 100% throughput to all admissible multicast traffic has been shown to be a very difficult task, and it requires a very high speedup in the switching fabric. In this paper, we introduce the...
