Quality of Service Comparison of Seamless Multi -Protocol Level Switching and Multi-Protocol Level Switching Networks

Abstract

A seamless MPLS network is one in which Multi-Protocol Level Switching is used for all packet forwarding within the network, from the time a packet enters the network until it leaves it. Seamless Multi-Protocol Level Switching was created with the goal of providing an architecture that can handle a wide range of services on a single Multi-Protocol Level Switching. Access, aggregation, and the core network are all integrated into one platform. The goal of traffic engineering is to make network operations more effective and dependable while also maximizing network resource consumption and traffic performance. Because of the high cost of network infrastructure and the commercial and competitive nature of the Internet, traffic engineering has become an essential function in many big Autonomous Systems. These issues highlight the need of maximizing operational efficiency. Traffic oriented performance objectives include the aspects the Quality of Service of traffic streams. In a single class, best effort Internet service model, the key traffic-oriented performance objectives include: minimization of packet loss, minimization of delay, minimization of jitter and maximization of throughput. The primary goals of Quality of Service are bandwidth management, controlled jitter, latency and improved packet loss characteristics to provide satisfactory services for users. The goal of this thesis is to improve the quality of service on multi-protocol level switching that is seamless. Two scenarios are used to examine the influence on Quality of Service parameters: one with Seamless Multi-Protocol Level Switching and the other with Resource Reservation Protocol -Traffic Engineering Seamless Multi-Protocol Level Switching. To compare the performances of the two situations, simulation tools such as Graphical Network Simulator-3, Ostinato, Paessler Router Traffic Grapher, and excel are utilized. On various Quality of Service metrics, the result demonstrates that Resource reservation protocol Seamless Multi-Protocol Level Switching is superior than Seamless Multi-Protocol Level Switching.
