Bandwidth Constrained IP Multicast Traffic Engineering Without MPLS Overlay

Overview Existing multicast Traffic Engineering (TE) solutions tend to use explicit routing through MPLS tunnels. This paper shifts away from this overlay approach and address the bandwidth constrained IP multicast TE directly based on link state IGP routing protocols. The objective is that, through plain PIM-SM shortest path routing with optimized Multi-topology IS-IS (MISIS) link weights, the resulting multicast trees are geared towards minimal consumption of bandwidth resources. The paper applies Genetic Algorithms (GA) to the calculation of optimized M-ISIS link weights that specifically cater for engineered PIM-SM routing with bandwidth guarantees.
