Segment Routing (SR) will revolutionize routing in the MPLS backbone. By extending the routing protocols to include label distribution with global significance, the use of an additional protocol such as LDP can be dispensed with. However, this alone would not be a reason to replace LDP. SR also promises to eliminate the many disadvantages of classic MPLS traffic engineering (TE) with RSVP signalling and, in conjunction with SDN controllers, to make TE scalable, optimized and manageable. In addition, an SR network has the ability to guarantee fast rerouting (FRR) for all links in the backbone and can be seamlessly integrated into an existing MPLS backbone. However, SR can also score points outside the MPLS backbone with its simple and scalable source routing concept with application options for service chaining or egress load sharing.

- Motivation and comparison with the classic MPLS solution
- SR architecture with MPLS data plane
- SR architecture with IPv6 data plane
- SR integration in IS-IS, OSPF and BGP
