    摘要: Embodiments of the invention provide flow control of incoming data packets to data processing resources via a controller that can receive and react to advanced backpressure messages. These advanced backpressure messages are used to rate limit the data packets based one or more of the following factors: traffic class, traffic priority, destination port. The controller can also generate a traffic preference message to an upstream source of the data packets to inform the upstream unit of the most appropriate type of data that should be transmitted downstream at that time, thereby improving the likelihood of the transmitted data being processed in a proper and timely manner by the downstream data processing resources. Embodiments of the invention can improve the performance of a communications system during periods of congestion by ensuring that high-priority traffic has precedence over traffic of lower priority while maximizing utilization of the ingress data path bandwidth.

    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: 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: Communication traffic policing apparatus and methods are disclosed. Communication traffic restrictions for each communication link in a group of communication links are enforced by allowing transfer of communication traffic associated with respective communication links of the group at transfer rates up to respective per-link transfer rates. In a group enforcement stage, transfer of additional communication traffic associated with a communication link of the group, above the per-link transfer rate for the communication link, is allowed where a combined transfer rate of communication traffic associated with another communication link of the group and the additional communication traffic would not exceed the per-link transfer rate for the other communication link. Thus, one or more individual communication links of a group may be allowed to effectively exceed their per-link transfer rates if one or more other communication links of the group have sufficient spare capacity.

    摘要: To avoid under-run conditions that result in corrupt packets at I/O interfaces, a FIFO buffer controller monitors key aspects of the contents of FIFO buffers of I/O interfaces. The FIFO buffer controller initiates transmission of data from the FIFO buffer when at least one complete packet is stored in the FIFO buffer or when the size of a partial packet stored therein is large enough so that the remainder of the packet would normally be received by the FIFO buffer before the stored part can be transmitted from the FIFO buffer; thereby avoiding an under-run error condition.

    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.
