摘要： An intelligent network interface card (INIC) or communication processing device (CPD) works with a host computer for data communication. The device provides a fast-path that avoids protocol processing for most messages, greatly accelerating data transfer and offloading time-intensive processing tasks from the host CPU. The host retains a fallback processing capability for messages that do not fit fast-path criteria, with the device providing assistance such as validation even for slow-path messages, and messages being selected for either fast-path or slow-path processing. A context for a connection is defined that allows the device to move data, free of headers, directly to or from a destination or source in the host. The context can be passed back to the host for message processing by the host. The device 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 devoted to transmit, receive and utility processing, providing full duplex communication for four Fast Ethernet nodes.

摘要： The present invention relates to a data storage unit for a communication system node, a method for data storage and a communication system node. More particularly it relates to storing buffering data and control data in a unit located outside of a Communication Controller on system or host-controller level, wherein a time-triggered protocol runs on the node. By locating control and buffering related data, including format and behavior, outside the Communication Controller it becomes far more flexible, extendable, and re-configurable as data buffering related restrictions, e.g. buffer sizes and number of buffers, are moved from Communication Controller level to system level.

摘要： A network element including a processor with logic for managing packet queues including a queue of free packet descriptors. Upon the transmission of a packet by a host application, the packet descriptor for the transmitted packet is added to the free packet descriptor queue. If the new free packet descriptor resides in on-chip memory, relative to queue manager logic, it is added to the head of the free packet descriptor queue; if the new free packet descriptor resides in external memory, it is added to the tail of the free packet descriptor queue. Upon a packet descriptor being requested to be associated with valid data to be added to an active packet queue, the queue manager logic pops the packet descriptor currently at the head of the free descriptor queue. Packet descriptors in on-chip memory are preferentially used relative to packet descriptors in external memory.

摘要： A method and apparatus to reduce memory required in a network interface controller to store per flow state information associated with a network connection is provided. Instead of storing per flow state information for a connection in the network interface controller at an endpoint of the connection, the per flow state information for the connection is stored in memory external to the network interface controller. The stored state information is conveyed in a packet by the network interface controller between the endpoints of the connection. For a Transmission Control Protocol (TCP) connection, the state information is conveyed between the endpoints of the TCP connection in a TCP option included in the TCP header in the packet.

摘要： A logic system in a data packet processor is provided for selecting and releasing one of a plurality of contexts. The selected and released context is dedicated for enabling the processing of interrupt service routines corresponding to interrupts generated in data packet processing and pending for service. The system comprises, a first determination logic for determining control status of all of the contexts, a second determination logic for determining if a context is idle or not, a selection logic for selecting a context and a context release mechanism for releasing the selected context. Determination by the logic system that all contexts are singularly owned by an entity not responsible for packet processing and that at least one of the contexts is idle, triggers immediate selection and release of an idle one of the at least one idle contexts to an entity responsible for packet processing.
