Abstract:
   The Path Computation Element (PCE) provides path computation
   functions in support of traffic engineering in Multiprotocol Label
   Switching (MPLS) and Generalized MPLS (GMPLS) networks.

   The Source Packet Routing in Networking (SPRING) architecture
   describes how Segment Routing (SR) can be used to steer packets
   through an IPv6 or MPLS network using the source routing paradigm.  A
   Segment Routed Path can be derived from a variety of mechanisms,
   including an IGP Shortest Path Tree (SPT), explicit configuration, or
   a Path Computation Element (PCE).

   Path identification is needed for several use cases such as
   performance measurement in Segment Routing (SR) network.  This
   document specifies extensions to the Path Computation Element
   Communication Protocol (PCEP) to support requesting, replying,
   reporting and updating the Path Segment ID (Path SID) between PCEP
   speakers.
