Abstract

See full text

A network device for processing data includes at least one ingress module for performing switching functions on incoming data, a memory management unit for storing the incoming data and at least one egress module for transmitting the incoming data to at least one egress port. The at least one egress module includes an egress scheduling module and multiple queues per each of the at least one egress port. Each of the multiple queues serve data attributable to a class of service, and the egress scheduling module is configured to service a minimum bandwidth requirement for each of the multiple queues and then to service the multiple queues to allow for transmission of a maximum allowable bandwidth through a weighting of each of the multiple queues.
