Abstract

A method for supporting transport of data packets in a network, wherein the data packets are transmitted from a source node to a destination node by employing a tunnel from a first tunnel endpoint to a second tunnel endpoint, wherein a tunnel header is added to the data packets at the first tunnel endpoint, wherein the data packets are transmitted between the tunnel endpoints via a network domain that includes one or more intermediate nodes functioning as transport network, and wherein the intermediate nodes forward the data packets, is characterized in that the tunnel is provided in the form of a virtual tunnel by removing the tunnel header from the data packets where the data packets enter the network domain and adding back the tunnel header to the data packets where the data packets exit the network domain. A corresponding system for supporting transport of data packets is disclosed.
