A communication network used to link information handling systems together utilizes a switching network to transmit data among senders and receivers. Each individual packet of data is described and controlled by an FCB. The bandwidth associated with the storing and distribution of data is optimized by chaining the data packets in different types of queues, or operating without chaining outside a queue. When a frame is in an output queue, the third word contains an RFCBA for egress of the frame to a line port, and an MCID for ingress from an output queue to a switch port. The RFCBA and the MCID have multicast capabilities. The format does not require a third word when a frame is in an input queue.
A frame control block for use in a network communication system having a network architecture, said frame control block containing information describing and managing a frame comprising a packet of data, and having a flexible format for a specified description and manipulation of the associated frame, the flexible format comprising multiple fields containing information based upon the location of the frame either within a queue or outside of a queue.
An integrated circuit for a network architecture and utilizing a plurality of frame control blocks, each of which contains information describing and managing a frame comprising a packet of data, and has a flexible format for a specified description and manipulation of the associated frame, the flexible format comprising multiple fields containing information based upon the location of the frame.
A network communication system utilizing a plurality of frame control blocks, each block containing information describing a frame comprising a packet of data and having a flexible format for a specified description and manipulation of the associated frame, the flexible format comprising multiple fields containing information based upon the location of the frame either within a queue or outside of a queue.
A method for describing and manipulating a plurality of data packets comprising providing a frame control block for each data packet, each frame control block having a flexible format composed of multiple fields containing information based upon the location of the data packet.
An article of manufacture comprising a medium usable in a network processor and having a computer readable program embodied in said medium, wherein the computer readable program, when executed on a computer, causes the computer to execute the following operations:
