PROBLEM TO BE SOLVED: To provide a hierarchical distributed routing architecture including at least three levels or layers, for receiving, processing, and forwarding data packets between network components.SOLUTION: Core level router components receive an incoming packet from a network component and identify a distribution level router component on the basis of the processing of a subset of a destination address associated with the received packet. The distribution level router components receive a forwarded packet and identify a transit level router component on the basis of the second processing of at least the subset of the destination address associated with the received packet. Transit level router components receive the forwarded packet and forward the packet to a respective network. The mapping, or other assignment, of portions of the FIB associated with the distributed routing environment is managed by a router management component.SELECTED DRAWING: Figure 4 |
