At least one data-stream is re-routed and a network element is provided for re-routing at least one data-stream. A first part and a second part of a data-stream received at a first node and are transmitted to a second node via two different network paths, respectively. The first is transmitted from the first node to the second node via a first network path. A second network path is determined, and the difference between latencies of the first and second network paths is also determined. If the latency of the first network path is larger than the latency of the second network path, the at least one data-stream at the first node is re-routed from the first network path to the second network path provided that the time gap between data packets received by the first node exceeds said difference between latencies.
