Geotagging IP Packets for Location-Aware Software-Defined Networking in the Presence of Virtual Network Functions
Tamraparni Dasu, Yaron Kanza, Divesh Srivastava · 2017
A substantial portion of global telecommunication is based on the Internet Protocol (IP), where IP packets are routed from a source host to a destination host via a communication network. While there is some loose connection between IP addresses and geospatial locations, associating packets to geographic coordinates merely according to IP addresses is hard, and often infeasible in real-time, given the rapidity and prodigious volume of packet traffic via routers and switches. This obstructs using geospatial information about the origin, destination, or route of IP packets or flows.
