| dc.description.abstract | Internet Service Providers (ISPs), are requiring better performing MPLS networks. Seamless MPLS (S-MPLS) provides an end-to-end MPLS networks by integrating access, aggregation and core networks into a single MPLS domain, improving the performance of MPLS networks. The ISP network performance can also be further enhanced by implementing Traffic Engineering (TE). However, in S-MPLS Traffic Engineering (S-MPLS-TE), some of the tunnels fail to find a path and re-route traffic in the network when the best path goes down or gets congested. Software Defined Networking’s (SDN’s) Path Computation (PCE) feature can provide an approach to overcome these shortcomings of S-MPLS-TE. In this thesis, the performance of S-MPLS-TE coupled with SDN is analyzed and compared with S-MPLS-TE. In order to carry out the research, literatures relevant to S-MPLS-TE and SDN are reviewed. Based on the literatures reviewed, a simulation network, for S-MPLS-TE and SDN coupled S-MPLS-TE simulation, is setup using GNS-3, OpenDaylight controller, Ostinato, Postman and PRTG. The topology of the simulation network setup is based on Ethio telecom’s access, aggregation and core networks. For the setup, ISIS, MPLS, BGP-LU, BGP-LS, PCEP, NETCONF and RESTCONF are utilized as networking protocols. In the simulation, latency and packet loss of both S-MPLS-TE and SDN coupled S-MPLS-TE simulations are measured, analyzed and compared for 250Kbps and 350Kbps TCP traffic scenarios. By coupling SDN with S-MPLS-TE, latency is enhanced by 12.26% in 250Kbps traffic scenario and by 16.07% in 350Kbps traffic scenario. Regarding packet loss, a 13.79% improvement in 250Kbps traffic scenario and a 22.667% improvement in 350Kbps traffic scenario are observed. | en_US |
