Method of detecting a routing loop in a telecommunication network, telecommunication network for using the method, and detection means for use in the telecommunication network

摘要

Known methods of detecting routing loops in telecommunication networks are cumbersome and time-consuming. In addition, the probability that an existing routing loop is even actually detected is too low. In a method of detecting a routing loop according to the invention, paths whose lengths are stored are assembled. As soon as the length of a (partly assembled) path exceeds a predetermined value which is greater than, or equal to, the largest existing path length in the telecommunication network, this indicates the existence of a routing loop.
