A method and apparatus compute a path in a network domain. The method mainly includes: first, a Path Computation Element in a network domain stores a global path computation information for computing the path in the network, the global path computation information includes: all the current request information for computing a path, the current network resource information for allocating or the occupying information of the current resource; then, the Path Computation Element computes a path according to the stored global path computation information. Consequently, the invention can improve greatly the efficiency and importance of processing the path computation by synchronizing the network state with the Path Computation Element; meanwhile, the invention can effectively avoid the conflict during the path computation, in addition, can reasonably and effectively partake the load of the request for computing a path and improve the whole operating efficiency of the protocol. |
