Mechanism for invoking and servicing multiplexed messages with low context switching overhead

A computer program product for processing requests for service within a multi-threaded distributed object system, the computer program product comprising:

• computer code arranged to listen for a request for service which includes a header and a message using a first server side thread, the first server side thread being arranged to listen for and to process requests on a connection of a server side end point of a server;
• computer code arranged to read the header of the request using the first server side thread, the header containing information pertaining to the message contained in the request;
• computer code arranged to determine whether the first server side thread is effective for processing the request;
• computer code arranged to read the message contained in the request;
• computer code arranged to service the request, wherein the computer code is arranged to service the request using the first server side thread when it is determined that the first server side thread is effective for processing the request;
• and
• a computer readable medium that stores the computer codes.

A distributed object system capable of processing a request for service, the distributed object system comprising:

• a central processing unit;
• memory that is allocated for processing the request for service;
• a client arranged to dispatch the request for service to a server using an object request broker which provides transport mechanisms necessary to dispatch the request for service;
• at least one server side thread resident in the memory, the server side thread having the capability of both listening for and processing requests for service, wherein the server side thread is associated with transport mechanisms on the server;
• and
• at least one client side thread resident in the memory, the client side thread having the capability of both dispatching requests for service and listening for replies to requests for service, wherein the client side thread is associated with transport mechanisms on the client.

A computer apparatus for use in processing requests for service within a distributed object system, the computer apparatus comprising:

• a central processing unit;
• an input/output device coupled to the central processing unit;
• random access memory in communication with the central processing unit, the random access memory including at least one thread with the capability of listening for requests, determining whether the at least one thread is suitable for processing the requests, and processing the requests when it is determined that the at least one thread is suitable for processing the requests;
• and
• a mass storage device in communication with the central processing unit.

A computer apparatus for use in processing requests for service within a distributed object system, the computer apparatus comprising:

• a central processing unit;
• an input/output device coupled to the central processing unit;
• random access memory in communication with the central processing unit, the random access memory including at least one client-side thread with the capability of both dispatching requests and listening for replies in response to dispatched requests;
• and
• a mass storage device in communication with the central processing unit.
