Improved Two-Level Method of Multicast Routing in MPLS-TE Network

This paper proposed the improved two-level method of multicast routing in MPLS-TE network. The original method is focused on implementation of load-balanced multicast routing in accordance with the principles of technology of Traffic Engineering. The method defined the tasks of two hierarchical levels: solution of the routing problem (lower level) and prevention of link overload in the MPLS network (upper level). The improvement of method consisting in modification of link overload prevention conditions will provide reducing the number of iterations of the coordination procedure by approximately in 1.5-5 times
