    摘要: A data plane architecture enables IP applications, hosted on any processor within a network element, to define steering policies that may be implemented in the data plane. The steering policies enable the applications to define steering policies containing both attributes and actions. The attributes are used to identify the packets and the actions are used to define how the data plane of the network element should handle the packets. The steering policies are implemented in the data plane of the network element by a data path policy steering process. The data path policy steering process operates to implement steering policies defined by applications to cause IP termination to occur at any processor on the network element or optionally at a processor off the network element.

    摘要: A data traffic policer includes a classifier for separating a packet stream in accordance with class, a first bucket for a first traffic class representing a first transmission rate and a first burst capacity and a plurality of second buckets for a plurality of second traffic classes representing a corresponding second transmission rates and a second burst capacities, the plurality of second buckets being nested within the first bucket thereby being subordinate to the rate and capacity of the first bucket, with the rate of the second bucket being disabled when a fill condition exists in the first bucket. The second bucket for a second traffic class may include a plurality of buckets for a corresponding plurality of traffic classes, with each bucket of the plurality of buckets having a corresponding capacity and rate. The rate defined as a corresponding weight.

    摘要: A method and system for data packet forwarding is provided. A forwarding information base is stored. The forwarding information base has a first stage with a first lookup key and a second stage with a second lookup key. The first lookup key is a portion of the second lookup key. The first stage is evaluated using the first lookup key forwarding the data packet is forwarded if the first stage evaluation yields a forwarding result. If the first stage evaluation does not yield a forwarding result, the second stage is evaluated using the second lookup key to determine a forwarding result. Such a method and system are suitable for use, among other places, in a network processing unit (“NPU”) in an IPv6 network.

    摘要: Inter-class schedulers for digital link systems provide high efficiency utilization of limited bandwidth by employing queuing techniques referred to as Statistical Priority Guarantee Queuing (SPGQ) and Generic Cell-Rate Algorithm Priority Guarantee Queuing (GCRA-PGQ). SPGQ “elevates” the priority of otherwise low-priority classes under prescribed circumstances in accordance with a statistical process. The SPGQ scheduler determines whether a number within a range produced by a uniform random number generator lies within a sub-range proportional to the programmed statistical guarantee for a given class. If the number lies within the sub-range associated with a given class, then the priority of that class is elevated to a higher priority when both are eligible to transmit. The GCRA-PGQ scheduler operates as a strict priority mechanism until a class requires bandwidth in excess of a GCRA “window” or threshold for that class. When that occurs, the service priority of that class is temporarily lowered.

    摘要: In Asynchronous Transfer Mode (ATM) communications networks, certain congestion control features, such as Partial Packet Discard (PPD) and Early Packet Discard (EPD), operate on ATM cells that have been segmented from ATM Adaptation Layer #5 (AAL5) frames (packets). AAL5 frames are automatically detected by observing transitions of an indicator in the ATM cell header unique to AAL5 traffic. Automatic detection of AAL5 traffic allows enablement of packet-aware cell discarding techniques such as PPD and EPD on a Virtual Channel Connection (VCC) basis, whether in a switch for a VCC or for a Virtual Path Connection (VPC) to which the VCC belongs.
