Abstract: Computer systems linked to nodes in a communication network communicate directly with each other to establish name associations for entities (e.g. programs, storage files, etc.) susceptible of being shared across the network, and thereafter communicate further by names (rather than addresses) to establish sessions (i.e. logical connections over the network) between entities. Each system maintains a table of names assigned to locally accessible entities. The name and session establishment processes are architected to avoid dependence on any "central" or "master" system, and to allow for extension of communications relating to these processes across devices linking portions of the network associated with different communication media or channels.

Abstract: A data processing system has files stored on disks in a tree structure of directories and files. The system is operated to rapidly open files which have been recently opened or for which partial path information is available, by accessing a drive cache (30) in main memory (16). The cache has entries chained in a tree structure which is then searched to provide the same information during the opening process as that information which would otherwise have to be obtained from a disk (22). When the cache is full, a new entry replaces the least recently used entry.

Abstract: The present disclosure concerns a method for allowing for adoption of names either on a unique basis (association of the name with one and only one entity) or a non-unique basis (association of one name to plural entities), in a data communication system that allows communicating processors to act without reliance on a common directory to adopt logical names for respective locally attached entities (programs, data files, human operators, etc.), and to initiate sessions relative to remote entities by means of communications directed to respective entity names (rather than addresses associated with the physical locations of respective entities). Names adopted on a non-unique basis are flagged as such in the adopting system, and name checking communications directed to such names are ignored by processors serving the respective entity (thereby allowing the checking processors to adopt the respective non-unique name, using the existing procedure for adopting unique names, and thereby enabling processors serving a group of entities to adopt a common name for directing network communications to the entire group concurrently). The disclosure describes specific communication applications made possible by this non-unique naming capability. (Fig. 6)
