A parallel packet switch (PPS) provides huge aggregate bandwidth by combining the capacities of multiple switching fabrics. Most existing PPSs use output queued switches as the switching fabrics, which require speedup and result in high implementation cost. In this paper, we present a buffered crossbar based parallel packet switch (BCB- PPS), whose switching fabrics need no speedup. We propose the...
Recent development in VLSI technology makes it feasible to integrate on-chip memories to crossbar switching fabrics. Switches using such crossbars are called buffered crossbar switches, in which each crosspoint has a small exclusive buffer. The crosspoint buffers decouple input ports and output ports, and reduce the switch scheduling problem to the fair queueing problem. In this paper, we present...
Fairness in traffic management can improve the isolation between traffic streams, offer a more predictable performance, eliminate transient bottlenecks, mitigate the effect of certain kinds of denial-of-service attacks, and serve as a critical component of a quality-of-service strategy to achieve certain guaranteed services such as delay bounds and minimum bandwidths. In this paper, we choose a popular...
