Evaluating Segment Routing Technology for MPLS-based Network

Abstract

Multi-protocol label switching (MPLS) has proved its strength for large network traffic since it emerged. However, due to increasing demands on network services and for a massive traffic that continually growing, Segment Routing was developed and introduced to overcome the limitation in load balancing and scalability of current MPLS. This paper examines the effectiveness of the SR technique for MPLS-based networks with Traffic Engineering (TE) via experimental work where an implementation of basic SR scenarios is emulated and tested for some comparison criteria. These criteria were based on packet analysis for both simple ICMP and flow in stable conditions and for network convergence in case of failure. Simulation results confirm the effectiveness of SR in MPLS-TE-based networks in terms of convergence and reducing overhead traffic control.
