Enabling Client Systems to Discover Services Accessible by Remote Procedure Calls (RPC) on Server Systems

摘要

Information representing the RPC servers, on which each RPC service is currently being provided, is maintained on a directory server. A client may query the directory server and determine a specific one of the RPC servers on which to cause execution of a desired RPC service. Each RPC server may also register the service interface using which the corresponding RPC services can be accessed. As a result, the same RPC service may potentially be accessed with a different service interface on different RPC servers. Another aspect of the present invention provides a schema using which procedure interface definition (i.e., the name of the procedure, the parameters, and their attributes) can be represented. Such a feature is used to store the procedure definitions on the directory server, thereby enabling a client system to determine the procedure definition prior to sending an RPC request to execute the procedure.
