`ABSTRACT
`
`A system for protocol processing in a computer network has
`an intelligent network interface card (INIC) or communica(cid:173)
`tion processing device (CPD) associated with a host com(cid:173)
`puter. The INIC provides a fast-path that avoids protocol
`processing for most large multi-packet messages, greatly
`accelerating data communication. The INIC also assists the
`host for those message packets that are chosen for processing
`by host software layers. A communication control block for a
`message is defined that allows DMA controllers of the INIC
`to move data, free of headers, directly to or from a destination
`or source in the host. The context is stored in the INIC as a
`communication control block (CCB) that can be passed back
`to the host for message processing by the host. The INIC
`contains specialized hardware circuits that are much faster at
`their specific tasks than a general purpose cpu. A preferred
`embodiment includes a trio of pipelined processors with
`separate processors devoted to transmit, receive and manage(cid:173)
`ment processing, with full duplex communication for four
`fast Ethernet nodes.
