    摘要: The present invention relates to a method and apparatus for reserving network resources for pseudo point-to-point connections by means of an idempotent resource reservation protocol.
    A method according to the invention comprises the steps of:
    - encoding, into a resource reservation signaling message (rsvp_path12, rsvp_resv12),
    a group identifier (GID0) assigned to a group of pseudo point-to-point connections (MS-PW4..7) established between a root node (T-PE0) and at least one leaf node (T-PE4..7),
    and a sub-group identifier (SGID12) assigned to a sub-group of pseudo point-to-point connections (MS-PW4..5) out of the group of pseudo point-to-point connections, which sub-group of pseudo point-to-point connections sharing a common network tunnel (TUN12) established between a previous signaling hop (S-PE1) and a next signaling hop (S-PE2),
    - aggregating, into the resource reservation signaling message, resource reservation signaling related to the sub-group of pseudo point-to-point connections by means of the group identifier and the sub-group identifier,
    - exchanging the resource reservation signaling message between the previous signaling hop and the next signaling hop.

    摘要: The invention presents an improvement to the OSPF routing protocol with respect to the handling of opaque LSAs. The delay in the establishment of fully adjacent routers is avoided by proceeding with the adjacency determination even if the opaque link-state database is not synchronized. The present invention segments the synchronization process and adds, on top of the database synchronization process known from RFC 2328, a synchronization process dedicated to the opaque LSAs.
