METHOD FOR SELECTING A LOGICAL LINK FOR A PACKET IN A ROUTER

摘要

A method and apparatus for transferring data packets over a router (100) comprising interface units (104) and a central switching unit (106). When a packet is received in the router, a logical link is selected for outputting the packet towards its destination, wherein the logical link comprises a plurality of packet queues with differentiated traffic classes. Further, a packet queue of the logical link is selected, and the packet is scheduled for launch from the selected queue, based on retrieved intermediate link descriptors and further based on a required QoS.(Fig. 1)
