METODO DE SUPORTE DE USO DE NOME ATRAVES DE REDES DISPERSAS DE PROCESSAMENTO LIGADAS POR PONTES E/OU PASSAGENS

For facilitating data communication between entities in a local area network (storage files, programs, devices, human operators, etc.), a method is disclosed for addressing such communications to logical names adopted for the entities; rather than to discrete physical locations in the network. The subject method allows for extension of name-directed communications across bridges (between separate communication media or between discrete frequency channels on one medium). Extensions of such communications across bridges are conditioned on the handling of respective communications within the channel or medium leading to respective bridges. If a named entity is reachable within a channel or medium leading to a bridge, the communication will be acknowledged by the processing facility at the node serving that entity, and the communication will not be extended. With the present method, a program running on a processor at one node of the network may call for retrieval of a data set by name, where the location of the data set need not be known or specifiable by either the program or the processor, and the respective data set may be retrieved through a process of communication which is entirely transparent to the program and processor, and also not ambiguous or burdensome when ■ the network path to the named data set contains bridges and/or gateways.
