摘要： A system and method for controlling overall behavior of a network processor device implemented in a network processing environment servicing a communications network. The method includes steps of receiving a guided control frame including one or more control functions for configuring various functional devices within the network processor with device control parameter data; a step of forwarding one or more control functions from a received control frame to a functional device within the network processor to be configured; and, executing the control functions as specified in the control frame. A novel control frame data structure and communications infrastructure is implemented whereby any network processor device operating in a distributed network processing environment may be controlled in accordance with executed control functions and device control parameter data.

摘要： A method and system for memory management in a network processing system provides for allocation of physical memory areas within network processors coupled to a control point processor by a bus. The allocation scheme provides a memory management layer without requiring a complete operating system interface and supports asynchronous completion of the allocation requests. Multicast allocation is supported allowing an allocation to be simultaneously requested on multiple network processors. The allocation mechanism returns a token, which may then be used to access the memory location via a protocol over the bus, and a single token may refer to an allocation made on several network processors where the actual physical addresses and memory configurations are different.

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： The transport protocol for communicating between general purpose processors acting as contact points and network processors in a packet processing environment such as Ethernet is provided. In such an environment, there is at least one single control point processor (CP) and a plurality of network processors (NP), sometimes referred to as blades. A typical system could contain two to sixteen network processors, and each network processor connects to a plurality of devices which communicate with each other over a network transport, such as Ethernet. The CP typically controls the functionality and the functioning of the network processors to function in a way that connects one end user with another, whether or not the end user is on the same network processor or a different network processor. There are three types of communication provided; first, there is communication generally referred to as control services and normally there will be only one pico processor which operates as a GCH (guided cell handler) and only one that operates as a guided tree handler (GTH). A path is provided for the controls to the GCH and the GTH commands, and a separate path is provided for the data frames between the GDH's (general data handler) and the CP.

摘要： A system and method of protocol and frame classification in a system for data processing (e.g., switching or routing data packets or frames). The present invention includes analyzing a portion of the packet or frame according to predetermined tests, then storing key characteristics of the packet for use in subsequent processing of the frame. The key characteristics for the frame (or input information unit, such as the type of layer 3 protocol used in the frame, the layer 2 encapsulation technique, the starting instruction address and flags indicating whether the frame uses a virtual local area network, preferably using hardware to quickly and in a uniform time period. The stored key characteristics of the packet are then used by the network processing complexes in its further processing of the frame. The processor is preconditioned with a starting instruction address and the location of the beginning of the layer 3 header as well as flags for the type of frame. That is, the instruction address or code entry point is used by the processor to start processing for a frame at the right place, based on the type of frame. Additionally, additional instruction addresses can be stacked and used sequentially at branches to avoid additional tests and branching instructions.
