Improvement of Multiprotocol Label Switching Network Performance using Software-defined Controller

In this work, we propose an improved MPLS network by separating the level of control from the data transmission level. To do this the MPLS controller in network architecture has been entered. This controller performs the functions of managing the quality of service by dynamically assigning labels. The process of forming the LSP tunnel of an existing MPLS with the proposed solution is considered. The effectiveness of MPLS and MPLS with controller technologies by the network's time delay in the process of packets transmit has been estimated.
