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.

A new report by Radware finds that "of the top 100 retail websites, the median page has grown 67% in just one year and many are failing to leverage advanced techniques to help accelerate their pages .. use of images is one of the single performance drains, as most site owners are not taking advantage of image optimization techniques that can dramatically improve both real and perceived load times
