We have just performed basic delay performance comparison with MPLS, SR-MPLS, and SRv6 in a small network case study with Cisco Modeling Lab (CML) and the initial results are very promising. SRv6 has about 48% improvement over original MPLS and 10% improvement over SR-MPLS. This delay improvement mainly due to the lack of LDP in Segment Routing approach. Perhaps later we can check other performance metrics as well and without LDP the node processing overheads will also be much better as well compared to the original MPLS. Scaling to the size of the global internet should further increase the improvement margins even more.
