Abstract
The Internet service provider (ISP) need more advanced MPLS networks for improved performance. The MPLS protocol tries its best to provide good service, but it does not guarantee traffic priority or quality. The Seamless MPLS (S-MPLS) technology improved performance by integrating both aggregate and core networks into one MPLS domain. However, there are some problems that make it hard to control the amount of data being used and the path that data takes when there is a lot of internet traffic. Implementing QoS in S-MPLS can also enhance ISP network performance. However, QoS in Seamless MPLS allows headend routers in an AS to optimize traffic routing without considering the needs of other AS routers. Using SDN-based Seamless MPLS QoS will be able to see the entire network topology of different domains, monitor of the status of the links, add or remove forward traffic information and guarantee end-to-end quality of service.
The inspiration of this proposal is to examine and analyze impacts of QoS actualizing in seamless MPLS with SDN based seamless MPLS. This study examines the effects on Quality of Service (QoS) parameters through the analysis of four distinct scenarios Seamless MPLS, QoS Seamless MPLS, SDN based Seamless MPLS and QoS SDN based Seamless MPLS with Several different domains are combined into one large MPLS domain. Simulation tools like GNS3, Ostinato, and Wire shark are used to compare how well the four scenarios perform.
The analysis results show that in QoS SDN based Seamless MPLS throughput is improved by 14.7%, latency is improved by 12.8%, and packet loss is improved by 18% compared to Best Effort Seamless MPLS. Based on the research findings, it is evident that the adoption and implementation of Quality of service (QoS) Software Define Network (SDN) based Seamless Multi-Protocol Label Switching (MPLS) can confer various benefits in service provider core network.
