METHODS AND SYSTEMS FOR NETWORK PACKET ROUTING USING EMBEDDED GEOGRAPHIC ROUTING INFORMATION

摘要

Systems and methods for network packet routing using geographic information, for example, for routing packets in an IP communication network using geographic routing information embedded in a packet's IP address. One method comprises assigning a device's geographic location and including in its IP address a subnet prefix and a portion comprising an identifier indicative of the device' geographic location. One method facilitates routing of a packet by addressing the packet to a destination device with an IP address comprising a subnet prefix and a portion comprising an identifier indicative of the device's geographic location. The method may further comprise routing the packet from a source device to the destination device using the identifier. One embodiment is a system of a subnet of IP compatible nodes. One or more of these node devices are assigned an IP address comprising a subnet prefix identifying its respective subnet and a portion comprising an identifier indicative of its geographic location. One or more router nodes may be capable of using the geographic location of an IP address in a packet to route the packet, for example to select to which subsequent node to send the packet.
