摘要： A number of ports are configured in a linecard in a network device as dedicated ports and a remaining number of ports as shared ports. A total bandwidth allocated to the dedicated ports is computed. It is determined that available bandwidth at a central crossbar is greater than the total bandwidth allocated to the dedicated ports. The total data sent the central crossbar is rate limited to less than the available bandwidth at the central crossbar. First data associated with the dedicated ports is scheduled to the central crossbar using a first priority. Second data associated with the shared ports is scheduled using a second priority. A shared port data is scheduled based on a ration of a bandwidth requirement for the shared port as a fraction of overall bandwidth requirement for the shared ports.
