A dual-end recursive PCE-based computation procedure (DRPC) is
proposed to compute shortest constrained inter-domain traffic
engineering label switched paths based on BRPC in Multi-protocol
Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. By
recursively performing shortest path algorithm and transferring the
segmental path computation result from both ends bi-directionally,
they meet at one of the Middle PCEs, generating a directional
shortest path graph into which the two shortest path trees are
stitched together. Therefore, the end-to-end constrained inter-
domain traffic engineering label switched path, even k shortest paths
can be gained from the directional shortest path graph directly.
