Claim:
1. A system, comprising: a plurality of connection nodes, each comprising an access interface and at least one network interface; a plurality of aggregation layer devices, each of which is coupled to respective sets of connection nodes to form aggregation regions, wherein each of the plurality of aggregation layer devices comprises an Internet Protocol (IP) address server associated with a pool of IP addresses for allocating to user devices connected to a connection node coupled to the aggregation layer device; a backhaul network coupled to each of the aggregation layer devices; and a mobility entity coupled to the backhaul network, wherein each of the connection nodes is configured to receive attachment requests from at least one user device, wherein the aggregation layer devices are configured to assign IP addresses, from the pool of IP addresses, to user devices connected to connection nodes coupled to the respective aggregation layer devices, wherein the aggregation layer devices are configured to determine IP routes from the backhaul network to the connection nodes based on the assigned IP addresses; and wherein the aggregation layer devices are further configured to notify respective connection nodes regarding the IP addresses assigned to connected user devices.
