A method and system for forwarding data units in a communications system, that comprises: ingress routers (901) capable of forwarding data units and containing a Forwarding Equivalence Class table (911) that contains mapping information, intermediate routers (905, 907, 909) capable of forwarding data units, egress routers (903) capable of forwarding data and containing a Forwarding Equivalence Class table (919) that contains mapping information. The method comprising the steps of: assigning a first label on data unit and a second label on data unit based on mapping information, sending data unit in to egress router via one or more intermediate router (905, 907, 909), receiving (903) data unit, identifying data unit based on mapping information on Forwarding Equivalence Class table (919) and based on second label. The method further comprises the steps of: creating a Forwarding Equivalence Class for radio access network specific data units; and storing information about Forwarding Equivalence Class in Forwarding Equivalence class table (FEC). |
