It is described a method of computing a path (71, 72) for a data connection in a network (1), wherein a requesting entity (2) requests a data connection, which provides a particular quality of service, and wherein a path computation element (51, 52) of the network (1) computes a path (71, 72) through the network (1) for the requested data connection. The requesting entity (2) sends a time limit to the path computation element (51, 52), within the requesting entity (2) expects a result from the path computation element (51, 52). In succession the path computation element (51, 52) estimates a time for path computation and reports the inability to compute the path (71, 72) within the expected time back to the requesting entity (2) if the estimated time is above the expected time. Furthermore, a path computation element (51, 52) and a network (1) allowing the presented method to be executed are disclosed. |
