Distributed computing system
First Claim
1. An improved computer system, the improved computer system executing a multiprocess operating system, the multiprocess operating system creating a plurality of processes for executing programs and one or more name spaces, each of the processes being associated with a current one of the name spaces and the name space associated with a given process being a set of names of entities in the computer given process being the set of names of entities in the computer system which are referencable by the given process in executing its program, and the improvement comprising:
- new name space creation means in the operating system which are usable by any one of the processes in executing its program to create a new name space for the process executing the program which is separate from the current name. space for the process and replaces the current name space for the process.

Abstract
An operating system which is particularly adapted to heterogenous distributed systems. Entities available to a process running in the operating system are provided by services. Each service models its entity as a set of files. The entity is controlled by performing operations on the set of files provided by the entity. Services other than those provided by the operating system all employ the same protocol specifying operations on files. The only requirement placed on a service by the operating system is that it be able to accept and respond to messages employing the protocol. The files are named, and the operating system provides a plurality of name spaces, relates each process to one of the name spaces, and permits any process to modify its name space or to create a new name space. Services are disclosed which provide each process using the service with its own set of the service'"'"'s files and which provide files belonging to one process'"'"'s namespace to another process executing on a different processor.
