5G brings with it the promise of a range of new services from the faster speeds of enhanced mobile broadband to mass deployment of machine-type communications to ultra-reliable low-latency applications. With this range of services comes a pressing need to design network infrastructure that can easily and efficiently support a range of service types. In IP/MPLS networks, deterministic, SLA-based services were traditionally supported by implementing traffic engineering using protocols such as RSVP-TE. This approach, however, was complex and difficult to scale and as a result saw only limited deployment in service provider networks. Segment Routing (SR) was conceived as an approach to solve these problems and provide a foundation for support of SLA services, reliability, and performance in core router networks. Its ability to run over any data plane and to leverage cloud-based path computation has made it a natural complement to the introduction of SDN. Clients, please log in to view the full content.
