Abstract:
Methods, apparatuses, and computer-readable medium for providing a fairness protocol in a network element are disclosed herein. An example method includes receiving one or more packets at each of a plurality of ingress ports of the network element, and scheduling the packets into a plurality of queues, wherein each of the queues is associated with packets that are sourced from one of the ingress ports. The method also includes monitoring a bandwidth of traffic sourced from each of the ingress ports, identifying a port among the ingress ports that sources a smallest bandwidth of traffic, and arbitrating among the queues when transmitting packets from an egress port of the network element by giving precedence to the identified port that sources the smallest bandwidth of traffic. Additionally, arbitrating among the queues distributes a bandwidth of the egress port equally among the ingress ports.
