Abstract
A method for load balancing traffic among routers in a data transmission system that includes a network, a set of routers, and a plurality of groups of servers. Each group of servers transfers its flow of data to the network through a first router, the address of which is assigned by a routing protocol. The load on the first router is compared periodically with a predetermined high threshold. If the load exceeds the high threshold, the priority of the first router is lowered in order to transfer the flow of data to a second router. If the load on the first router is subsequently found to be less that a predetermined low threshold, the priority of the first router is increased in order to transfer the flow of data from the second router back to the first router.
