    摘要： A system for interconnecting widely separated local area networks (LANs) (11,12) by means of a wide area network (WAN) (10) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point (13,14) which allow subsequent data frames to be transmitted through the wide area network without such network level operations. More particularly, the various LANs are combined into search groups, represented by address prefixes, to which LAN-initiated connection requests can be broadcast and which can respond so as to establish the data path connections. This system has the connection flexibility of a prior art router and, at the same time, the low overhead of a prior art bridge.

    摘要： A packet communications system provides for point-to-point packet routing and broadcast packet routing to limited subsets of nodes in the network, using a routing field in the packet header which is processed according to two different protocols. A third protocol is provided in which a packet can be broadcast to the limited subset even when launched from a node which is not a member of the subset. The routing field includes a first portion which contains the route labels necessary to deliver the packet to the broadcast subset. A second portion of the routing field contains the broadcast subset identifier which can then be used to deliver the packet to all of the members of the broadcast subset. Provision is made to backtrack deliver the packet to the last node identified before the broadcast subset if that last node is itself a member of the subset.

    摘要： A congestion control system for packet communications networks in which access to the network is controlled to prevent such congestion. Packets within the pre-specified statistical description of each packet source are marked as high priority ("green" packets) while packets exceeding the pre-specified characteristics are marked with a lower priority ("red" packets). The overall red packet rate is limited to prevent red packet saturation of the network. The introduction of red packets into the network is subjected to a degree of hysteresis to provide better interaction with higher layer error recovery protocols. The amount of hysteresis introduced into the red packet marking can be fixed or varied, depending on the statistics of the incoming data packets at the entry point to the network.
