摘要： A communication technique for high volume connectionless-protocol, backbone communication links in distributed processing systems provides for control of latency and reliability of messages transmitted. The system provides for transmit list and receive list processes in the processors on the link. On the transmit side, a high priority command list and a normal priority command list are provided. In the message passing process, the command transmit function transmits commands across the backplane according to a queue priority rule that allows for control of transmit latency. Messages that require low latency are written into the high priority transmit list, while a majority of messages are written into the high throughput or normal priority transmit list. A receive filtering process in the receiving processor includes dispatch logic which dispatches messages either to a high priority receive list or a normal priority receive list. The filtering function also acts to drop messages received according to the amount of available buffer space in the receiving processor, as measured against watermarks based on reliability tags in message headers. The messages received are routed to either the high priority receive list or a normal priority receive list based on another control bit in the message headers. The receiving processor processes the messages in the receive queues according to a priority rule that allows for control of the latency between receipt of a message, and actual processing of the message by the receiving processor.

摘要： A high performance scalable networking bridge/router system is based on a backbone communication medium and message passing process which interconnects a plurality of input/output modules. The input/output modules vary in complexity from a simple network interface device having no switching or routing resources on board, to a fully functional bridge/router system. Also, in between these two extremes input/output modules which support distributed protocol processing are supported. A central internetworking engine includes a shared memory resource coupled to the backbone. The architecture includes a physical layer communication system for transferring control messages and data packets across the backbone, a logical layer interprocessor messaging system which operates over the physical layer across the backbone for communication between intelligent input/out modules, and between such modules in the central internetworking engine, and distributed protocol modules which are supported on intelligent input/output modules, and communicate using the logical interprocessor messaging system with the central internetworking resources.

摘要： A system uses a message passing paradigm for transferring large amounts of input/output data among a plurality of processors, such as a network intermediate system or router. A bus interconnects the plurality of processors with a plurality of bus interface devices. The bus interface device which originates a transfer includes a command list storing lists of commands which characterize transfers of data messages from local memory across the bus and a packing buffer which buffers the data subject of the command being executed between local memory and the bus. A bus interface device which receives a transfer includes a free buffer list storing pointers to free buffers in local memory into which the data may be loaded from the bus, and a receive list storing pointers to buffers in local memory loaded with data from the bus. The command list includes a first high priority command list and a second lower priority command list for managing latency of the higher priority commands in the software of the processor. The bus interface which receives the transfer includes control logic which manages data transfer into and out of an inbound buffer, including receiving burst transfers of message transfer cells from the bus, loading free buffers in local memory from the inbound buffer with message transtar cells, and updating the receive list. The receive list includes a first higher priority receive list and a second lower priority receive list for reliability management, and logic which monitors the free list so that lower priority messages may be dropped to prevent overflow of free buffer resources.

摘要： A reverse address resolution protocol for use in a communication network which allows resolution logic to provide a higher level protocol information (such as an IP address) to a source of a request for such information, independent of the physical network address of such source. The protocol is used in a processor having a plurality of ports, at least one of such ports connected by a point-to-point channel to a remote network device. Reverse address resolution protocol is responsive to a resolution request from the remote network device across the point-to-point channel to supply the higher level protocol information based upon the port through which the resolution request is received, rather than the physical network address of the requesting device. Thus, a remote device may be coupled to a network, and connected to a central management site across a point-to-point communication link, in a "plug and play" mode. The person connecting the device to the remote network does not need to determine the physical network address of the device or configure the device with a higher level address protocol.

摘要： One embodiment of the invention includes a method of managing network communications in a network device. The network device includes software components and modules. Some of the components control the interaction between modules, while other components perform specific functions for associated modules. A module manager component controls the creation and destruction of modules as well as their interactions. A communications manager component manages network communications in the network device. The network communications is supported by creating a number of modules that are associated with components that implement different parts of a network protocol. As a result of the use of the modules, a component need not know which other component(s) it depends upon, nor need it know which other component(s) depend upon it. This allows components to be used together very easily in many different configurations. The modules also allow the same component to be used by multiple modules.
