Abstract

Apparatus and methods for incorporating a portion (including all) of a first name space into a second name space. An agent operating in the first name space receives first operation specifiers which use names as they are used in the second name space from an entity operating in the first name space and translates the first operation specifiers into second operation specifiers which specify the same operations and use the names as they are used in the first name space. The apparatus and methods are implemented in the Plan 9 operating system. The first and second name spaces areorganized as trees and belong to a first process operating on a first processor and a second process operating on a second processor. The first operation specifiers are Plan 9 file protocols which the first process receives from the second process. The second operation specifiers are Plan 9 file system calls made by the first process.
The translation between the file protocols and the system calls is made using a data structure which permits the names in the portion as they are used in the second name space to be mapped onto the names as they are used in the first name space.
