Stateless Load Balancing Over Multiple MPLS Paths

The paper proposes a flow-independent approach to balance the load coming from several multimedia applications (i.e., IP Telephony) over multiple paths between a source and a destination. The proposed strategy exploits the advanced path-controlling and packet-forwarding features of the MPLS technology to set up the paths computed by the routing algorithm. Simulations reported in the paper show that the stateless approach increases the acceptance ratio (and thus the network utilization), while keeping the end-to-end delay and jitter within acceptable levels.
