Abstract
Systems (10), nodes (11, 12) and methods for load balancing telecommunication sessions over a dual ring Internet Protocol (IP) network (100) allow load balancing between first and second rings (1, 2) of the IP network. Transmission quality is determined by monitoring packets received over the first ring from a first IP subnetwork (21) of one or more remote sites and monitoring packets received over the second ring from a second IP (22) subnetwork of the one or more sites. A determination is made as to which one of said first and second rings (1, 2) is associated with the highest packet transmission quality towards a site based on the monitoring. Packets of a call session can be exchanged between nodes over the same one of the first and second rings (1, 2) associated with the highest packet transmission quality between sites containing the nodes.
