DISTRIBUTED ROUTING ARCHITECTURE
First Claim
1. A system for routing packets comprising:
- a router management component, executed on a computing device, for associating destination address information to a router hierarchy;
one or more router components corresponding to a first level of the router hierarchy, the first level of the router hierarchy for receiving an incoming packet for routing;
one or more router components corresponding to a second level of a router hierarchy, the second level of the router hierarchy for processing an incoming packet for routing received from at least one of the one or more router components corresponding to the first level of a router hierarchy;
wherein the one or more router components corresponding to the first level of a router hierarchy identifies one or more router components from the one or more router components corresponding to the second level of a router hierarchy based on a first subset of a destination address associated with the incoming packet, wherein the first subset is assigned by the router management component;
wherein each of the one or more router components corresponding to the second level of a router hierarchy correspond to portions of the first subset of the destination address associated with the incoming packet; and
wherein the one or more router components corresponding to the second level of a router hierarchy identifies an outgoing transit path based on a second subset of a destination address associated with the incoming packet, wherein the second subset is assigned by the router management component and wherein the second subset of the destination address is greater than the first subset of the destination address.

Abstract
A hierarchical distributed routing architecture including at least two levels, or layers, for receiving, processing and forwarding data packets between network components is provided. The core level router components receive an incoming packet from a network component 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 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.

13. A system for routing packets comprising:
-
a first set of logical router components for receiving an incoming packet for routing; a second set of logical router components for routing packet received from the first set of router components; an external transit component for routing packets received from the second set of router components wherein the first set of logical router components identify a router from the second set of logical router components based on a correlation by a router management component of a subset of the destination address associated with the incoming packet to the selected router; wherein each of the one or more router components corresponding to the second set of logical router components is allocated by the router management component to correspond to portions of the first subset of the destination address associated with the incoming packet; and wherein the second set of logical router components identify a routing path identified by the external transit component based on a correlation by the router management component of a second subset of a destination address associated with the incoming packet to the second selected router. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for routing packets comprising:
-
obtaining a routing request corresponding to a data packet received from a first communication network; identifying a first router corresponding to a first level of a router hierarchy, the first level of the router hierarchy corresponding to one or more router components; forwarding the received data packet to the identified first router; identifying a second router corresponding to a second level of the router hierarchy, the second level of the router hierarchy corresponding to one or more router components; forwarding the received data packet to the identified second router; and identifying a transit path corresponding to a communication network; wherein identifying the second router corresponding to a second level of the router hierarchy is based on a correlation of a subset of the destination address associated with the received data packet to the selected router; and wherein identifying the transit path is based on a correlation of a second subset of a destination address associated with the incoming packet to the second selected router. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
