    摘要: The process for determining the best communication route from a source end station to a destination end station is distributed over both source and destination network nodes. Network nodes, at the interface between a wide area network (WAN) and each subnetwork, contain access agents to control the communication flow between the wide area network and an end station in the subnetwork. The task of selecting the best route between two end stations is distributed between the access agents at the WAN interface in the first subnetwork, and the access agents at the WAN interface in the second subnetwork. Each access agent at one WAN interface obtains the best route from itself to the end station in its subnetwork. Each access agent at the other WAN interface finds the best route from each access agent at the first WAN interface through itself to the end station in its subnetwork. One designated access agent collects all the best route information. This best route information is concatenated, and the route with the least weight is selected as the best route between end stations.

    摘要: A method and arrangement is disclosed for extending a resource search across a gateway node connecting a peer-to-peer network with a subarea network. An interface node is divided into a first section associated with the peer network and a second section associated with the subarea network. In response to a resource search request arriving at one of the sections from the network with which the section is associated, a directory of resources known by the respective section is first searched. If the resource is not found in the directory of the section, the search request is translated into a format compatible with the other network, and the translated search request is transmitted to the other section of the interface node. If the resource is not found among the resources known to the interface node, the resources known by the end nodes served by the interface node in the peer network are next searched. If the resource is not found within these end nodes, the resources known by each of the remaining network and end nodes in the peer network are next searched. If the resource is still not found, a search of the subarea nodes of the second network is initiated.

    摘要: Routing information is distributed interdomain using a policy-based protocol and intradomain by flooding. A network device receives a message with routing information from outside its domain and applies policy. Policy filtered routing information is flooded throughout the domain of the network device. A link state advertisement header is added to the routing information to perform flooding. Policy is also applied to flooded routing information before sending such message to another domain.

    摘要: A system for interconnecting widely separated local area networks (LANs) by means of a wide area network (WAN) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point 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: An apparatus and method of configuring a first network device that is a part of a subnet ascertains configuration data from packets in a subnet having configuration dat. More particularly, the packets, which are transmitted by a second network device in the subnet, first are retrieved and then parsed to ascertain the configuration data. At least a portion of the configuration data is stored in a configuration database. In addition, at least one datum from the configuration data is processed to produce additional configuration data that also is stored in the configuration database. The first network device consequently operates in accord with the data in the configuration database.

    摘要: Access agents in nodes at the LAN/WAN interface are formed into a group of access agents so that the access agents may be managed by the WAN as a group. The group must maintain group operation integrity in that if communications between agents in the group are broken, the access agents will coalesce into subgroups and continue performing communication jobs as a group activity. Each of the access agents contains a finite state machine to perform the tasks of group formation and maintenance. The formation of interconnected access agents into a group is accomplished by one access agent being identified as a group leader. All other access agents communicating with the group leader within the LAN may then join the group. The maintenance of group activity integrity is accomplished by detecting a break in group communication integrity and thereafter reforming the group into multiple smaller groups. The maintenance of group operation integrity also includes the merger of small groups into a large group when a bridge is added between LAN segments.
