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.
摘要翻译：在LAN / WAN接口的节点中的接入代理被形成为一组接入代理，使得接入代理可以由WAN作为一组进行管理。该组必须维护组操作完整性，因为如果该组中的代理之间的通信中断，则访问代理将合并成子组并继续执行通信作业作为组活动。每个访问代理包含一个有限状态机来执行组的形成和维护任务。将互连的接入代理组合成一组是由一个接入代理被识别为组长。所有与LAN内的组长通信的其他访问代理可以加入该组。群体活动完整性的维护是通过检测组通信完整性的突破，然后将组重组成多个较小的组来实现的。群组运行完整性的维护还包括在LAN段之间添加桥梁时将小组合并成大型组。

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： The present invention is a general solution to the problem address incompatibility between application programs and transport services. The invention may be embodied in a method for mapping the application program address (program address) to the transport services address (transport Provider address). According to the method, a program address is registered in the network so that it becomes available to other programs that understand the address, even if they are running over a transport protocol that does not understand the address format. When a request is made that a connection be established between a program and a program partner or that a datagram be sent therebetween, the program address is mapped to the transport Provider address (if necessary). The program address is then conveyed to the program partner so that it knows who it is talking to.
