Abstract:
   The Path Computation Element (PCE) working group (WG) has produced a
   set of RFCs to standardize the behavior of the Path Computation
   Element as a tool to help MPLS-TE, GMPLS LSP tunnels and Segment
   Routing paths placement.  This also include the ability to compute
   inter-domain LSPs or Segment Routing path following a distributed or
   hierarchical approach.  In complement to the original stateless mode,
   a stateful mode has been added.  In particular, the new PCInitiate
   message allows a PCE to directly ask a PCC to setup an MPLS-TE, GMPLS
   LSP tunnels or a Segment Routing path.  However, once computed, the
   inter-domain LSPs or Segment Routing path are hard to setup in the
   underlying network.  Especially, in operational network, RSVP-TE
   signaling is not enable between BGP border routers.  But, such RSVP-
   TE signaling is mandatory to setup contiguous LSP tunnels or to
   stitch or nest independent LSP tunnels to form the end-to-end inter-
   domain LSP tunnels.  This draft propose to combine a Backward
   Recursive method with PCInitiate message to setup independent LSP
   tunnels per domain and stitch or nest the different LSP tunnels to
   setup end-to-end inter-domain LSP tunnels without the need of inter-
   domain signaling between BGP border routers.  A new Stitching Label
   definition and new LSP-TYPE code points are proposed for that
   purpose.
