| dc.description.abstract | Multiprotocol Label Switching ( MPLS) Segment Routing (SR), SR-MPLS in short, is an MPLS data plane-based source routing paradigm in which a sender of a packet is allowed to partially or completely specify the route the packet takes through the network by imposing stacked MPLS labels to the packet. SR-MPLS could be leveraged to realize a unified source routing mechanism across MPLS, IPv4 and IPv6 data planes by using an MPLS label stack as unified source routing instruction set while preserving backward compatibility with traditional MPLS networks. The Segment Routing is a promising Traffic Engineering (TE) model that provides end-to-end communications. SR can observably improve the network utilization and control the routing path flexibly by encoding route information into a list of segments, i.e., the Segment List (SL). The key feature of SR is that it adopts the source routing paradigm, which implies the routing path followed by a packet is determined and written to the packet header by the first switch of SR networks (called Ingress SR switch). The motivation of this thesis is to investigate and analyze the impact of implementing SRMPLS on Quality of Service (QoS). The impact on QoS parameters is analyzed by using two scenarios; Traditional Unified MPLS integrating four domains into single MPLS domain and Segment Routing over Unified MPLS integrating four domains into a single MPLS domain. Simulation tools such as EVE-NG, Ostinato, Cisco IPSLA technology are used to compare performances of the two scenarios. The analysis results show that in SR-MPLS throughput is improved on average by 32%, latency is improved by 24%, packet loss is improved by 20.4% and jitter is improved by 12.6% compared to Label Distribution Protocol (LDP) based Unified MPLS. From the results, one can understand that any service provider can benefit from deploying Unified SR-MPLS. Segment Routing is a new routing paradigm that provide a better end-to-end QoS guarantee, making traditional MPLS network more efficient and scalable. | en_US |
