Abstract

Methods and apparatus are provided for a enterprise-wide work flow system that may encompass multiple geographically separate sites. The sites may be either permanently or transiently linked. A single computer network may accommodate multiple work flow systems and a single work flow system may be distributed over multiple local area networks. The system maintains the paradigm of one global queue per service and provides for individual work flow systems to export services to one another in an enterprise.

Claims

1. A method of distributing an object in a computer environment comprising a plurality of interconnected computer networks, wherein the object is to be sent from a local network to a remote network, the method comprising:

providing each computer network with a queue for storing objects destined for the remote network;

circulating a load balancing work object to each one of the networks in the plurality of interconnected computer networks such that the load balancing work object visits each of the networks at least once;

when the load balancing work object visits the local network, examining the queue on the local network and selectively embarking into the load balancing work object information relating to work objects stored in the queue that are destined for the remote network; and

,

when the load balancing work object visits the remote network, selectively debarking from the load balancing work object information relating to the work objects destined for the remote network.

2. The method of claim 1 wherein circulating, selectively embarking, and selectively debarking are repeated at least once.

3. A method of distributing an object in a multiple work flow system environment, the method comprising:

providing each work flow system in the multiple work flow system environment with a queue for storing objects destined for another work flow system;

circulating a load balancing work object to each one of the work flow systems such that the load balancing work object visits each of the work flow systems at least once;

when the load balancing work object visits each work flow system, examining the queue and selectively embarking into the load balancing work object information relating to work objects stored in the queue that are destined for another work flow systems; and

selectively debarking from the load balancing work object information relating to the work objects destined for the visited work flow system.

4. The method of claim 3 wherein circulating, selectively embarking, and selectively debarking are repeated at least once.
