Creating and managing dynamic MPLS tunnel by using SDN notion

Abstract

The aim of this research is using the notion of Software Defined Network (SDN) in creating and managing a Dynamic Multi-Protocol Label Switching (MPLS) tunnel in Open Shortest Path First (OSPF) network. The created tunnel has higher flexibility in terms of allocated path hops and reserved bandwidth. The path of the tunnel can be changed dynamically according to the present requirements of the network as well as its reserved bandwidth which can be changed according to the applied flow data rate. This provides faster path restoration and allows better utilization to the network resources. Moreover, it improves traffic engineering and achieves better Quality of Service (QoS) which results in more reliable network.
