ABSTRACT:
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.
