APPARATUS AND METHODS FOR MAKING A PORTION OF A FIRST NAME SPACE AVAILABLE AS A PORTION OF A SECOND NAME SPACE

摘要

Apparatus and methods for incorporating a portion (including all) of a first namespace into a second name space. An agent operating in the first name space receivesfirst operation specifiers which use names as they are used in the second name spacefrom an entity operating in the first name space and translates the first operationspecifiers into second operation specifiers which specify the same operations and usethe names as they are used in the first name space. The apparatus and methods areimplemented 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 asecond process operating on a second processor. The first operation specifiers arePlan 9 file protocols which the first process receives from the second process. Thesecond 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 datastructure which permits the names in the portion as they are used in the second namespace to be mapped onto the names as they are used in the first name space.
