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.
