摘要： Systems and techniques, including special messages and state machines, are described that configures an intermediate site to dynamically trigger creation of and removal of a dynamic conduit between two sites based on usage that is tracked at the sites. The intermediate site providing WAN-to-WAN forwarding between the two sites, monitors throughput statistics on each local WAN link (LWL) associated with the two sites. If traffic between the two sites passes a configured first threshold or if LWL usage passes a configured second threshold, the intermediate site sends a message to the two sites to set up a dynamic conduit directly coupling the two sites. Busy lists are used to keep track of eligible site pairs. Once a dynamic conduit is set up between two sites, a grow technique tests the dynamic conduit increasing communication flows between the two sites each configured sampling period before putting the conduit in normal use.

摘要： A network device including an ingress processor and egress processor which receives frames of data over the network on an input port, and transfers it to an appropriate output port. The received frame is processed by an ingress processor which prepares an intra-switch frame for delivery to an egress processor serving a relevant output port of the switch. The intra-switch frame includes a frame header having parameters which have been determined by the ingress processor, as well as data indicating an address for the egress processor for beginning processing of the frame. By identifying to the egress processor processing which has already taken place, the egress processor is relieved of any redundant processing of the frame. The egress processor provides a hardware frame classifier which decodes the information contained in the intra-frame header to derive parameters which have been previously computed as well as a starting address for the egress processor. By reducing the amount of redundant processing of the egress processor, total device throughput delay is reduced.

摘要： A method and system for downloading software managed trees (SMTs) in a network processing system provides dynamic update of frame classifiers while maintaining proper network protocol processing. The network processing system includes a general purpose processor acting as control point processor and a plurality of network processors. The new SMT is built by an application on the control point processor and downloaded to one or more of the network processors. The new SMT is placed in a separate memory location accessible to the network processors, rather then overwriting the existing SMT. The active tree pointers are then changed to transfer control to the new SMT.

摘要： A method and apparatus for processing network frames by embedding control information achieves an efficient frame processing system within a network processor (NP). The layer type of the frame can be quickly determined by the layer processing components of picocode running on the NP by examining control information that is written by ingress processing layers to produce a modified frame format. The frames are routed to appropriate layer processors and processing for certain layers may be bypassed if the picocode determines that no processing is required at that layer. The frame may also be discarded completely by any of the layer processors.

摘要： In a network processor-based device, there is provided a single routing table for network routers and an efficient routing algorithm implemented by the routing device. The routing table includes packet forwarding information including a subnet address associated with a destination address location, an ISO layer three (3) network protocol address, e.g., IP address, of a router interface that can route packets to the subnet address, and an identifier indicating whether that router is an exit BGP router that may or may not be directly attached to the packet forwarding router. A table look-up mechanism is provided to determine next hop information and determine associated BGP status of the next hop. At such time it is determined that a router is not a BGP router (i.e., is directly attached to the forwarding router), the packet will be transmitted to that router.
