Abstract
A scheduling system and methodology for use in a network switch element having multiserver, multiple-arbiter architecture. Ingress ports and egress ports coupled to the cross-connect fabric of the network element are provided with multiple ingress and egress arbiters, respectively, for effectuating an iterative arbitration strategy such as RGA or RG. Arbiter architectures include singe-arbiter-per-port; single-arbiter-per-server; multiple-arbiters-per-port; and multiple-arbiters-per-server arrangements, wherein the arbiters can be implemented using RRA, BTA, Flexible Ring, or any other arbiter technology. Depending on the iteration strategy, ingress arbiter architecture and egress arbiter architecture, a variety of iterative, multiserver-capable scheduling algorithms can be obtained, which scheduling algorithms can also be implemented in QoS-aware network nodes.
