Network protocols and performance analysis of mpls (multiprotocol label switching) with traffic engineering

NETWORK PROTOCOLS AND PERFORMANCE ANALYSIS OF MPLS (MULTIPROTOCOL LABEL SWITCHING) WITH TRAFFIC ENGINEERING MUSTAFA MAHMOOD HAMZA Erciyes University, Graduate School of Natural and Applied Sciences M.SC. Thesis, June 2017 Supervisor: Asst. Prof. Dr. MUSTAFA DANACI ABSTRACT Traffic Engineering (TE) is the feature of network engineering of optimizing network performance by detracting the network congestion that may occurs when data packets being transmitted through the network. Multiprotocol label switching (MPLS) is a modern technology for data packet forwarding, which enables administrators to define routes and ensures the Traffic Engineering Management in IP networks. Quality of service (QoS) metrics such as packet loss and latency are issues of interest since data packets have to be forwarded to the destination over long distances. Traffic engineering (TE) provides Quality of service QoS for various internet application. This thesis gives the practical comparison the performance between traditional IP, Multiprotocol label switching (MPLS), and multiprotocol label switching–Traffic Engineering (MPLS-TE) networks. In this thesis, Graphic Network Simulator (GNS3) has been used for simulation objective to design and implement the networks. According to simulation results, multiprotocol label switching–Traffic Engineering (MPLS-TE) showed better performance as compared to traditional IP and MPLS. Keywords: Traditional IP, MPLS, MPLS-TE, QoS, Latency, Packet Loss, congestion.
