摘要： A lightweight, low cost solution provides inter process communications (IPC) in a network processing environment. A method of inter process communication (IPC) between General Purpose Processors in a network processing environment uses software based functions (Application Program Interfaces (APIs)) that enable inter process communication between processors in a network processing environment. The software enabled functions open and close inter process communication paths for transmitting and receiving of inter process communication frames and allow the inter process communication frames to be transmitted to one or several processors in said network processing environment. The software has the capability of selecting either data or control path in said network processing environment to transmit or receive said inter process communication frames.

摘要： A method and system for providing remote procedure calls in a multiprocessing system is disclosed. The multiprocessing system includes a general purpose processor and a plurality of network processors. Each of the plurality of network processors includes a memory. The method and system comprises accessing a reserved address in at least one of the network processors and initiating a software action by a first portion of the reserved address. The method and system further includes pointing to an address within the memory of the at least one network processor to be processed based upon data in a second portion of the reserved address, wherein the data at the address is processed. A system and method in accordance with the present invention provides an indirect software jump in a microprocessing system through providing a reserved address in memory of each of the reserved address includes two portions. A first portion of the address triggers the software event requested by the general purpose processor (for example) and a second portion of the reserved address is utilized to process the data that was loaded at that address in the processor. The indirect software jump allows a general purpose processor to execute software on a network processor indirectly for custom application services or debug operations.

摘要： A method, system, program product, and data structure for processing network communication within a communication network from a general processor to a network processor. An informational frame is encapsulated into a packet for transmission within a communication network from a general processor to a network processor having a data processor and a control processor. If the informational frame is a control frame and the control processor is congested and if the control frame only needs message routing services from the locally connected network processor, the encapsulated packet is designated as a data-type packet so that the data processor processes the control frame. The encapsulated packet is then sent from the general processor to the network processor. The data processor decapsulates the encapsulated packet, parses the control frame and processes the control frame. The data processor directs and executes a control command defined within the control frame to a target control processor of a target network processor designated within the encapsulated packet.

摘要： A method and system for controlling a flow of a plurality of packets in a computer network is disclosed. The computer network includes a queue. The method and system include determining a queue level for the queue and determining an offered rate of the plurality of packets to the queue. The method and system also include controlling a transmission fraction of the plurality of packets to the queue, based on the queue level, the offered rate and a previous value of the transmission fraction so that the transmission fraction and the queue level are critically damped if the queue level is between at least a first queue level and a second queue level.
