Segment Routing is a technology gaining popularity for simplifying Multi-Protocol Label Switching MPLS networks. It has the advantage of interfacing with a software-defined network. SDN is an already well-established paradigm within the industry, making it easier to manage the network. Software-Defined Network and Segment Routing are used to solve these challenges and improve network performance. Segment Routing technology is a source routing paradigm for addressing the drawbacks of Multiprotocol label switching network in the term of simplicity and scalability. Increasing the number of customer scalability issues arises that limit the performance of a network. This implementation is used to address these drawbacks and improve demanding functionalities. Segment Routing was used to resolve these issues and evolve a system in the era of SDN. We have proposed a practical traffic engineering approach by combining Segment Routing and MPLS to distribute traffic engineering by specified custom routes using Postman Application and SDN-Controller. It is more comfortable for the network provider to manage a network. Segment routing technology makes it easy to assign a dynamic traffic engineering approach according to customer requirements from the high-level application. This thesis work presents the Implementation of Segment Routing and MPLS Traffic Engineering, based on the GNS3 network Emulator, Postman Application, and Open Daylight SDN Controller.
