A method for traffic engineering computation between the areas and a system, an equipment, a storage media thereof are in the network communication technical field. In the invention, in order to furthest and facilely using the network resource and improving the availability of the network resource, the path computation client sends the parallel traffic engineering path computation request to the multiple path computation elements in the same area (S110); the traffic engineering path computation request is forwarded to the path computation element in the other area (S120); the path computation element which has received the traffic engineering path computation request computes the path respectively according to the network resource state information maintained by itself, and returns the usable path to the path computation client (S130).
