Abstract:

The 5G technology brings new services such as the faster speeds of enhanced mobile broadband, mass deployment of machine-type communications, and ultra-reliable low-latency services. Consequently, it comes to a critical need to design a network infrastructure that can easily and efficiently support various service. Service Level Agreement (SLA) based services were traditionally established in the Internet Protocol / Multiprotocol Label Switching (IP/MPLS) network by implementing traffic engineering using protocols such as Resource Reservation Protocol - Traffic Engineering (RSVP-TE). However, it is not easy for some network operators to implement the current 5G development as mentioned earlier. Segment Routing (SR) presents as a technology to minimize network complexity and provide a fundamental for supporting SLA services, flexibility, reliability, and overall performance in the core of a network. In this study, we simulate and implement SR into MPLS Layer 3 Virtual Private Network (L3VPN) intra-AS domain to show that (i) reducing any transport protocol will not affect the service performance; instead, it simplifies service provisioning and problem handling (ii) when a network failure happens in the network, using Topology Independent Loop-Free Alternate (TI-LFA) and microloops avoidance can provide better failover time than conventional Fast Re-Route (FRR) (iii) SLA path differentiation for services within the same Virtual Routing and Forwarding (VRF) can be applied using Segment Routing - Traffic Engineering (SR-TE). It will be an essential foundation for network slicing in the future.
