This QoS can be varied based on deep inspection of the packets which can tell the operator as to what service a particular packet belongs to. The operators can thus give higher priority to the services and applications that are recommended by them and also block certain services that can be deemed as illegal or unproductive (like file sharing or P2P).
Continuous Computing claims to be one of the market leaders in producing the DPI systems. You can read this article by Mike Coward who is the CTO and Co-founder of Continuous computing here.
There is also this very interesting paper on QoS control in 3GPP EPS which is available freely here.
Please feel free to comment or suggest how do you see DPI being used in the future.
Continuous Computing provides h/w platforms (i.e. enabling technology) which some DPI vendors use to build DPI/QoS systems and devices.
ReplyDeleteThe DPI solutions market leaders are Sandvine, Allot Communications and Cisco.
Azi, thanks for pointing it out.
