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 communication system having a network architecture utilizing, a frame control block containing information describing and managing a frame containing 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, wherein said frame is in the output queue of a network processor and includes at least three words, the third word containing a reference frame control block address for egress of the frame to a line port and a multicast counter for ingress from an output queue to a switch port frame control block address, said reference frame control block address and multicast counter both having multicast capabilities.
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, each frame control block 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 or outside a queue, wherein the frame is in the output queue of a network processor and includes at least three words, the third word containing a reference frame control block address for egress of the frame to a line port and a multicast counter for ingress from an output queue to a switch port, said reference frame control block address and multicast counter both having multicast capabilities.
