Im curious how they will actually implement this. Block everything not going over port 80 or 443 and also block many other types of services? Deep packet inspection? New voice services and apps turn up all the time.
There is no way they can block "voice data" (their double speak not mine) without also bloking lots of other services, as collateral damage.
- mseebach 15y agoA voice stream is fairly easy to detect. Not many applications have a constant, symmetric flow of data. They don't have to keep you from establishing the connection in the first place, just cut it off or degrade it once detected.
- fpp 15y agoThere are ready to go solutions for that identifying specific applications (VoIP would be one of them) down to the provider of the solution (e.g Facebook, Skype). And yes this is done via DPI plus patterns etc. So it would not really matter (on the long run) if you would e.g. tunnel that on port 80. Most providers of such solutions by now fully integrate with the Telco's management platforms similar to "plug-ins". Current market estimates for these platforms (policy servers) and DPI are expected to grow to more than $5B over the next years. In Telco environments these things are generally covered under traffic management and the acronyms PCC or PCRF. I think TeliaSonera is using OpeNet in some of their countries since quite some time for that at least with 4G.
