INTERNET DRAFT     Location-Based Network Monitoring    October 30, 2016

Abstract

   IP Flow-based monitoring lacks a mechanism to associate measured IP
   Flow information with the geographic location of the device where the
   IP Flows have been observed. This document defines a set of
   guidelines and best practices to extend IP Flow monitoring protocols
   with location information of the device (both fixed and mobile) that
   acts as an IP Flow metering process.
