Abstract:
1. A method of providing differentiated QoS (quality of service) in an MPLS (multiprotocol label switching) based transport, comprising the steps of: establishing a single first label switching path having at least one label switching router, the first label switching path being a connection between a base station and a radio network controller, the base station having a plurality of traffic classes of traffic; establishing a single second label switching path having at least one further label switching router, the second label switching path being a connection between the base station and the radio network controller, the radio network controller having a plurality of traffic classes of traffic; assigning each label switching path at least one attribute in order to provide differentiated QoS to the plurality of traffic classes; marking a field of an MPLS header at a label switch router at an ingress to a respective label switching path of the first and second label switching paths to identify respective traffic classes of traffic being carried by a respective one of the base station and radio network controller; and forwarding the traffic within the respective label switching path based on the marked field.
