MPLS-TE, load balance, test-bed implementation.


MPLS is the dominant technology in most backbone networks. MPLS-TE is able to handle various paths along different routes to balance the traffic load between two points of the network. In this paper we present a load balancing algorithm (LC) designed to reduce network congestion. The algorithm presented has been tested by simulation and implemented in a MPLS Linux lab test bed. Observed results show that our algorithm is able to attain dynamic load balance while avoiding both undesirable oscillations and the need to fine tune external parameters.
