Abstract

A system, method, and computer program on a computer readable medium for allowing multiple controllers to communicate with other controllers through the use of a routing table are disclosed. The controllers do not need to be directly connected to each other as long as there is a path through other controllers to reach each other. Routing tables used to determine the optimal communications paths between controllers. These techniques are disclosed that allow the controllers to compute the optimal communications path between two controllers. A first technique computes the path which crosses the least number of controllers to reach the controller to which the message is being sent. A second technique is to compute the path which has the least data traffic crossing the controllers and the interconnects. A third technique combines the first two techniques in that it uses both pieces of information, the shortest route and minimal data traffic, to determine an optimal routing path.
