For a wireless network, communication nodes (such as a Mobile Switching Center) are disclosed that include at least ten small routers. The small routers handle traffic received from a plurality of base stations over a backhaul facility. The backhaul facility transports the traffic between the base stations and the small routers using Internet Protocol (IP). A small router in the communication node is defined as a router that is to handle 10% or less of the traffic for the communication node as configured. The percentage to be handled by a router is based on the configuration of the communication node.
