    摘要: An egress traffic management system for a data communication system is disclosed. The egress traffic management system makes use of a hierarchical queue ID header paradigm that enables data packets to be directed for egress traffic management to either one of a plurality of assignable queues in a main egress queue module or to one of a plurality of distributed queue modules via a common queue of the main egress queue module. This behavior enables egress traffic management functionality and scale to be varied independently and in a cost-effective manner to meet evolving requirements of a data communications system.

    摘要: Distributed communication traffic control systems and methods are disclosed. An amount of communication traffic received from a traffic management device and stored in a communication traffic queue at a communication device is monitored. Based on the amount of communication traffic stored in the communication traffic queue, a determination is made, at the communication device, as to whether a traffic management action is to be performed. If a traffic management action is to be performed, the traffic management device is controlled to perform the determined traffic management action. The traffic management device may receive an indication of the determined traffic management action from a distributed traffic controller in the communication device, for example, and perform the traffic management action responsive to the indication.

    摘要: A configurable chassis guidance system and method are described. The system may be practiced as a chassis and/or a module or an element thereof (e.g., a mating guide). The system and method allow reconfiguration of multiple modules of various module widths without the need for removal or reinstallation of module guides mounted on the chassis. As an example, a single-width module may be removed and replaced by a double-width module or quadruple-width module without removing module guides used to engage the single-width module. As another example, a double-width module or quadruple-width module may be removed and replaced by a single-width module without removing module guides used to engage the double-width module or quadruple-width module. The system and method may be practiced so as not to impair compatibility of modules with card edge module guides that engage an edge of a circuit board of a module.

    摘要: A method for communicating backpressure messaging over a serial encoded link is disclosed. Embodiments of the invention enable advanced backpressure signaling to be retrofitted into legacy systems to achieve performance improvements and support new or enhanced services. Specifically, such signaling enables per-context and per-priority backpressure signaling information to be conveyed by a backpressure message; thereby enabling flow control to be performed in accordance with a priority or context associated with a traffic flow, or flows, carried over the serial link.

    摘要: A method of reducing overhead for datagrams that are transmitted to or received from a serial link that reduces overhead to no more than four bytes. The datagram includes at least a Protocol Data Unit (PDU) field, a Start-of-PDU Header (SPH) field, and a SPH Control (SCH) field. The SPH and SCH fields consist of two bytes. The datagram may additionally include End-of-PDU Header (EPH) and EPH Control (ECH) fields. A method may also involve substitution of flags for subsequent headers that are identical to previous headers.

    摘要: Apparatus and method for implementing virtual path aggregation (VPA) of underlying virtual connections at a switching node of a connection based communications network. A multi-service traffic shaping module (MTSM) at the switch implements algorithms to aggregate the VC and VP connections onto the aggregate VP by representing an aggregate VP as a plurality of circular linked lists or loops and assigning each VC connection to a link or element in the circular linked lists according to traffic descriptors. Weighting factors are used as between loops to dynamically select the next loop to service. Once this loop is chosen, the next VC to be serviced is identified by examining the circular linked list structure.
