Segment Routing (SR) is a new MPLS paradigm in which each SR-capable router is required to advertise global MPLS labels or Segment IDs (SID) for its attached prefixes by using link-state IGPs, e.g., OSPF. One major challenge associated with such global MPLS label or SID advertisement mechanism is how to avoid a given global MPLS label or SID from being allocated by different routers to different prefixes. Although such global label or SID allocation collision problem can be addressed through… CONTINUE READING
