A hierarchical distributed routing architecture including at least three levels, or layers, for processing data packets is provided. The core level router components receive an incoming packet and identify a distribution level router component based on processing a subset of the destination address associated with the received packet. The distribution level router components receive a forwarded packet and identify a transit level router component based on at least a subset of the destination address associated with the received packet. The distribution level router components maintain address routing information a first and second memory. The transit level router components receive the forwarded packet and forward the packet to a respective network. The mapping of destination addresses to router components of may be managed by a router management component. Mapping of destination address to router components may be based, at least in part, on traffic volumes associated with the mapped destination addresses. |
