ABSTRACT:
A method and system for determining a route for a packet traveling over at least one system from a source to a destination is disclosed. A first geographic area corresponds to the source and a second geographic area corresponds to the destination. The destination further has an address which does not indicate the second geographic area. In this aspect, the method and system include associating an address for the destination with the second geographic area to allow selection of the route for the data packet based on the second geographic area and selecting the route based on a second geographic area. In a second aspect, the method and system include providing a direct link having a controllable amount of traffic and selecting the direct link as at least a portion of the route when a data packet to the destination is to be routed. The method and system also facilitate selection of a route for a data packet. In this aspect, the method and system include obtaining information relating to an autonomous system. The autonomous system has a geographic area. The information includes the geographic area. In this aspect, the method and system also include associating the autonomous system with the geographic area to allow selection of the route based on the geographic area.
