Abstract
A broadcast control system and its components capable of determining unique routes to deliver broadcast cells to every destination in an ATM network, which is designed to avoid network congestion and subsequent degradation in quality of service, as well as to reduce the workloads imposed on network equipment. The ATM network is organized by a plurality of network elements and at least one service provider terminal connected to a source network element. A broadcast routing controller disposed in the source network element distributes a broadcast routing control cell over the ATM network. Each network element on the network receives this broadcast routing control cell as well as its replicas delivered through different paths, and on the basis of information contained in those control cells, it establishes its own routing data in the local storage. This routing data indicates a particular link that is connected to the shortest path between the source network element and the present network element. When relaying broadcast cells, each network element selectively accepts broadcast cells coming through a particular link registered in the routing data and redistributes them to adjacent network elements.
