Abstract
Multi protocol Label Switching (MPLS) protocol is a network layer packet forwarding technology that provides flexible circuit switched traffic engineering solutions in packet switched networks by explicit path routing. They are an elegant solution to meet the Bandwidth management and QOS requirements of next generation IP-based backbone networks. One of the critical research issues in MPLS is Traffic engineering i.e., efficient mapping of the traffic flows on to the network and in effect enable QoS routing. In this paper, we propose a four-stage mapping of the incoming IP packet to the label in the control plane for creation of sub-FEC and sub-Label Switched Path (LSP), and CoS Based Lsp Selection (CBLS) algorithm in the data plane for dynamic selection of sub-LSP. This combined approach provides a circuit switched type of a service in a packet switched network for real-time applications like voice. We have evaluated the approach using ns2.26 and initial results are encouraging.
