A method of establishing a traffic route for a mobile network node attached to a mobile router, where the mobile router has a plurality of upstream interfaces available to it. The method comprises sending from the mobile router to the mobile node, identifiers of the interfaces and of their properties, the identifiers mapping to IPv6 traffic classes or IPv4 type of service. In the case of IPv6, the identifiers may be contained within router advertisement messages broadcast by the mobile router. At the mobile network node, an interface is chosen based upon the identified interface properties. The traffic class or type of service field of at least certain outgoing packets includes the identifier of the chosen interface. At the mobile router, packets are routed across the interface corresponding to the identifier contained in the traffic class or type of service fields, typically using rules created upon detection of a traffic class value in a packet header.
