Abstract
The present invention is a multi-protocol object distribution system. The multi-protocol object distribution system can include one or more remote procedure call (RPC) transport protocol stubs; and, a meta-stub configured to select individual ones of the RPC transport protocol stubs through which distributed object services can be provided to requesting clients in the object distribution system. The RPC transport protocol stubs can include both a default RPC transport stub, and at least one other RPC transport stub which the meta-stub can select based upon changing conditions in the object distribution system. Importantly, the meta-stub can automatically select the default RPC transport stub by default.
Claims10
A multi-protocol object distribution system comprising:
- a plurality of remote procedure call (RPC) transport protocol stubs;
- and
- a meta-stub processor configured to
- establish a communicative link with a distributed object using a default RPC transport stub,
- select an individual one of said RPC transport protocol stubs through which distributed object services can be provided to requesting clients in the multi-protocol object distribution system, and
- reestablish said communicative link using said selected individual one of said RPC protocol stubs;
- wherein
- said RPC transport protocol stubs comprises:
- the default RPC transport stub, and at least one other RPC transport stub;
- and
- the meta-stub processor further configured to:
- automatically select said default RPB transport stub by default, and
- select said at least one other RPC transport stub based upon changing conditions in said multi-protocol object distribution system.
In a multi-protocol object distribution system, a remote procedure call (RPC) processing method comprising:
- receiving an RPC request for services from a distributed object in a server in the multi-protocol object distribution system;
- establishing a communicative link with said distributed object using a default RPC transport mechanism, and querying said distributed object over said communicative link for other RPC transport mechanisms which are supported by said server;
- selecting one of said other RPC transport mechanisms based upon changing conditions in said multi-protocol object distribution system and re-establishing said communicative link with said distributed object using said selected RPC transport mechanism;
- and
- processing said RPC request for services from said distributed object over said re-established communicative link.
A machine readable storage excluding signals having stored thereon a computer program for performing remote procedure call (RPC) processing in a multi-protocol object distribution system, the computer program comprising a routine set of instructions for causing the machine to perform the steps of:
- receiving an RPC request for services from a distributed object in a server in the multi-protocol object distribution system;
- establishing a communicative link with said distributed object using a default RPC transport mechanism, and querying said distributed object over said communicative link for other RPC transport mechanisms which are supported by said server;
- selecting one of said other RPC transport mechanisms based upon changing conditions in said multi-protocol object distribution system and re-establishing said communicative link with said distributed object using said selected RPC transport mechanism;
- and
- processing said RPC request for services from said distributed object over said re-established communicative link.
