Remote procedure interface with support for multiple versions

摘要

A distributed computer system incorporating multiple computer processes enables a client computer process to request execution of a remote procedure on a server computer process even when the server computer process does not support a current version of the client computer process. A version map is utilized by the client computer process while requesting a remote procedure to format the request to a version supported by the server computer process, thus permitting client and server computer processes coresident in a distributed computer system to be upgraded independently while ensuring backward-compatibility with earlier versions.
