ISP's ability to detect and therefore limit bittorrent traffic with DPI is reserved for those customers that chose to disable the default torredo tunnelling and encryption on utorrent. I suspect that Xtra found this to their dismay when they pulled their 'big time' plan. The last bastion of hope for ISPs these days is to use heuristic traffic pattern analysis to detect usage behaviour. In any case the content remains encrypted.
I would be interested in knowing how the various firewall products that claim to provide L7 filtering of P2P manage this. Apparently Fortinet (as an example) can even pick P2P when the connection is using TLS or SSL. Call me a skeptic but I am not sure how they can do this. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Glen Eustace GodZone Internet Services, a division of AGRE Enterprises Ltd.
