    Patent number: 6374303
    Abstract: What is disclosed is an arrangement of field of label augmented, multi-protocol routing of data packets in a network utilizing fixed length labels that are negotiated between adjacent label routing routers in the network. Portions of each routing label may be assigned by both upstream and downstream routers in the network. Routing labels are used in lieu of conventional address headers to route data packets through said network; and by using routing labels the routers have more flexibility in routing data packets through said network and can use network links between routers that normally carry less traffic.
