Multipath routing model of multicast flows in telecommunication networks

In order to ensure the optimal load balancing in telecommunications network, the multicast routing flow-based model has been improved in the direction of implementing the multipath packet transmission strategy. It is suggested to split the original multicast flow into a set of subflows, for each of which an optimal tree is built as a multicast route. The problem of multipath multicast routing is presented in an optimization form, contributing to the most effective load balancing in the network. The application of the proposed model of multipath multicast routing allowed to improve the upper threshold of traffic congestion on the average from 17 to 25% compared to a singlepath solution.
