Abstract

A data management and distribution system has been described that includes router processes for controlling data communications between child processes running on computers connected by a network. Preferably, a router process runs on each computer, with the application processes running on the computer connected directly to the router process. As a result, all interprocess communications must pass through the routers. Each router process includes a connection table listing its connections with all other router and application processes, as well as an interest table listing the type of objects that each of the other processes are interested in receiving. Data communication is accomplished by an application process providing an object to its local router, which then distributes the object to all other interested routers. The object includes a destination list indicating which processes are to receive the object. Thus, with the use of routers, application processes that need to communicate with each other over a network need not know the intricate details (such as the communications protocol used, the exact address of the receiving process, etc.) involved in transmitting information. By placing the burden of managing the network communications on the local routers, the complexity of the application code is reduced since it has only a single connection to its local router.
