The presentation talks about the problem space and possible workarounds: MSD – Maximum SID Depth Generic concept defining number of SID’s, HW/SW are capable of imposing on a given node – Applicable to both, SR-MPLS (labels) and SRv6 (SRH’s) data planes Focus of this presentation is SR-MPLS data plane SID stack compression -Efficient path computation algorithms -Compressed SID stack that meets MSD limitations SID stack expansion -Instantiate a new SID stack at the node, within ingress’s MSD limits IETF work: draft-ietf-isis-segment-routing-msd draft-ietf-ospf-segment-routing-msd draft-tantsura-idr-bgp-ls-segment-routing-msd
