I am looking to start a Mesh WISP utilizing Cisco Aironet products (1500 series) and would like to know what is the best Cisco (or if the case has to be "non Cisco") product for measuring the amount of traffic from wireless clients connected to my Cisco Mesh.
Basically I want to be able to say User xyz has this IP xxx.xxx.xxx.xxx how much have they uploaded and how much have they downloaded this month.
This also then allows me to integrate multiple business mobile devices into their broadband plans which is something no-one yet offers in my City.
From what I have read Netflow is the measurement technology but how do I take this data and aggregate it by IP / User for billing purposes. Is there something better at it than Netflow? Your expert opinions and suggestions are much appreciated.
