摘　　要：Transport network paths are typically bidirectional and symmetrical, In multi-protocol label switching （MPLS） and generalized MPLS （GMPLS） mechanisms, independent labels are distributed for bidirectional paths. Thus, the requirement of the MPLS transport profile （MPLS-TP）, which is a new transport technology, could not be satisfied efficiently. A novel label distribution mechanism for bidirectional paths in MPLS-TP networks is proposed. Labels distributed by the mechanism are symmetrical and can reflect the pairing relationship of the forward and backward directions of the transport path.Transport network paths are typically bidirectional and symmetrical, In multi-protocol label switching （MPLS） and generalized MPLS （GMPLS） mechanisms, independent labels are distributed for bidirectional paths.
