`
`ABSTRACT
`(57)
`A system for protocol processing in a computer network .has
`an intelligent network interface card (INIC) or commumca(cid:173)
`tion processing device (CPD) associated with a host com(cid:173)
`puter. The INIC or CPD provides a fast-path that avoids host
`protocol processing for most large multipacket messages,
`greatly accelerating data communication. The INIC or CPD
`also assists the host for those message packets that are chosen
`for processing by host software layers. A communication
`control block (CCB) 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. ~he
`CCB can be passed back to the host for message processmg
`by the host. The INIC or CPD contains hardware circuits
`configured for protocol processing that can perform that spe(cid:173)
`cific task faster than the host cpu. One embodiment includes
`a processor providing transmit, receive and management pro(cid:173)
`cessing, with full duplex communication for four fast Ether(cid:173)
`net nodes.

`
`TECHNICAL FIELD
`
`The present invention relates generally to computer or
`other networks, and more particularly to protocol processing
`for information communicated between hosts such as com(cid:173)
`puters connected to a network.
`
`BACKGROUND
`
`The advantages of network computing are increasingly
`evident. The convenience and efficiency of providing infor(cid:173)
`mation, communication or computational power to individu(cid:173)
`als at their personal computer or other end user devices has led
`to rapid growth of such network computing, including inter(cid:173)
`net as well as intranet systems and applications.
`As is well known, most network computer communication
`is accomplished with the aid of a layered software architec(cid:173)
`ture for moving information between host computers con(cid:173)
`nected to the network. The layers help to segregate informa(cid:173)
`tion into manageable segments, the general functions of each
`layer often based on an international standard called Open
`Systems Interconnection (OSI). OSI sets forth seven process(cid:173)
`ing layers through which information may pass when
`received by a host in order to be presentable to an end user.
`Similarly, transmission of information from a host to the
`network may pass through those seven processing layers in
`reverse order. Each step of processing and service by a layer
`may include copying the processed information. Another ref(cid:173)
`erence model that is widely implemented, called T
