It will probably be throttled, yes - but the main problems (at least on the downlink) are for "legitimate" traffic like video content, web use, mapping and so on. <br /><br />Aggressive attempts to control these will significantly impact customer experience, especially where MBB is being positioned as a direct alternative to DSL / cable.<br /><br />In addition, all app-layer management is heavily prone to encrypted or tunnelled traffic, and also has very high risks of false-positives and false-negative. <br /><br />Also, for many PC-based applications it is not possible to discern flows at a network level at all, because of mashups etc. "Video" is not an application in the way that P2P protocols can be fairly well defined.<br /><br />As a user, my application is Facebook and I expect it to work - despite the fact that my FB page may have video, audio, flash etc etc embedded in it. The *app* is Facebook, not a Youtube clip whch happens to be displayed on my Facebook page.<br /><br />I'm expecting to see much more emphasis on subscriber-level management rather than app-level.<br /><br />DeanDean Bubleyhttps://www.blogger.com/profile/05719150957239368264noreply@blogger.comtag:blogger.com,1999:blog-17500930.post-59798930822114123732010-01-26T10:12:20.981+00:002010-01-26T10:12:20.981+00:00Why are you less convinced that traffic-management...Why are you less convinced that traffic-management at the application layer will not play a role? <br /><br />A lot of operators (both fixed and mobile) are using DPI solutions to throttle P2P traffic.<br /><br />Why this shall not be done in mobile networks as well?Davidenoreply@blogger.comtag:blogger.com,1999:blog-17500930.post-23326455395956923922010-01-20T20:33:25.470+00:002010-01-20T20:33:25.470+00:00The Forum Oxford link is brokenThe Forum Oxford link is brokenTelcoBPMhttps://www.blogger.com/profile/05206630115003443745noreply@blogger.com
