摘要： A method and a network device for sharing bandwidth among a group of classes of traffic for an interface are provided. Bandwidth may be allocated to at least one traffic class of a first priority for the interface. At least some unused bandwidth of the at least one traffic class may be allocated to at least one other traffic class of a second priority for the interface. In some implementations, weighted constituents may be allocated unused interface bandwidth based on an assigned weight of each of the weighted constituents of the interface.

摘要： At least a portion of the data units in a bridge/router are processed by logic circuits according to cast type. The cast type, source address and destination address of an incoming data unit are determined by examining the header. For a unicast data unit, the source address and destination address are employed to obtain a transmit port indicator from memory, and the unicast data unit is directed to the port indicated by the transmit port indicator. For a non-unicast data unit, the source address and destination address are employed to obtain a first port mask that indicates valid ports for receipt of the data unit and a second port mask that indicates valid ports for transmission of the data unit from memory. The first and second port masks are combined to generate a third port mask, and the non-unicast data unit is directed to the ports indicated by the third port mask.

摘要： A buffer memory may be configured to temporarily store data in a number of queues. A processor may be configured to measure a fullness of the buffer memory. The processor may also be configured to assign sizes to the number of queues based on the fullness of the buffer memory. The processor may also adjust thresholds of drop profiles associated with the number of queues based on the sizes assigned to the number of queues.

摘要： A method for sharing an aggregate bandwidth among a group of traffic classes may include allocating a portion of the aggregate bandwidth to one of the group of traffic classes having a first priority associated therewith, where the allocated portion is referred to as a first bandwidth. The method may include allocating an unused portion of the aggregate bandwidth to a second one of the group of traffic classes having a second priority associated therewith in conjunction with a parameter associated with a downstream device.

摘要： Quality of Service (“QoS”) variables for predetermined protocol Type data units are stored in a cache memory. For data units that are associated with a flow, thirteen bytes selected out of the Internet Protocol (“IP”) header are employed as at least a portion of a key to perform a cache lookup to obtain at least one Quality of Service variable from the cache. Both routing and QoS information may be stored in the cache for retrieval upon a single lookup operation.
