Multi-Service: A Service Aware Routing Protocol for the Next Generation Internet

Quality of Service support plays a major role in the Next Generation Internet. QoS routing protocols must cope with service differentiation to enhance this support. This paper proposes a service aware QoS routing protocol, the Multi-Service routing, which is an extension to traditional intra-domain routing protocols. It proposes a new path selection policy that guides higher priority traffic through the shortest path and diverts lower priority traffic through longer paths when service performance degradation is foreseen. Simulations results shows that the proposed routing performs better than existing QoS routing and linkstate protocols.
