Mobile Internet Gateway - Functions Explained

   
Following my announcement on creating the Mobile Internet Gateway Function Matrix (here), please find below a short description of the different gateway functions to be covered by the matrix.

Please note that some of the functions may be interrelated (like DPI and traffic steering, or tiered services and quota). Also, we can expect different levels of support in most functions (e.g. video optimization or DPI) and different levels of integration (single/multiple devices, integrated management, single policy view etc).

Nevertheless, I will start by the highest level: whether the function is part of the vendor's offering or not. As a ground rule, I will indicate a function as supported only if it is clearly presented in the vendor's web site. Again, vendors are invited to send their information to me directly.
