摘要： A method for supporting transport of data packets in a network, in particular service and/or user aware transport of data packets, wherein said 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 said data packets at said first tunnel endpoint, wherein said data packets are transmitted between said tunnel endpoints via a network domain that includes one or more intermediate nodes functioning as transport network, and wherein said intermediate nodes forward said data packets, is characterized in that said tunnel is provided in the form of a virtual tunnel by removing said tunnel header from said data packets where said data packets enter said network domain and adding back said tunnel header to said data packets where said data packets exit said network domain. Furthermore, a corresponding system for supporting transport of data packets is disclosed.
