Demonstration of segment routing with SDN based label stack optimization
Segment Routing (SR) architecture is a promising technology. It is being standardized in
collaboration between vendors and service providers. Through its simplistic control plane
and the reuse of existing data planes namely MPLS and IPv6, SR helps operators to reduce
the Operation Expense (OpEx) and the Capital Expense (CapEx). In the instantiation of SR
over the MPLS data plane (SR-MPLS), a SR path gets encoded as a label stack that the
ingress nodes push onto the client packet. However, the longer the path in term of traversed …
