I've been following the proliferation of mobile broadband traffic management technologies for some considerable time now, having published a reseach paper on the bewildering range of options a few months back.
The continued hoo-ha around Net Neutrality is starting to catalyse open warfare between the advocates of different approaches to solving the mobile capacity crunch.
WiFi vs. femtocell offload competition is nothing new, but it's interesting to see new rivalry springing up between other purveyors of policy management and control. Flash Networks, for example, is one of a number of vendors that compress/optimise traffic, especially video destined for transmission over cellular networks.
There is quite a lot that can be done at the interface between the operator's gateway and its main Internet peering point - reformatting video, changing codecs or frame-rates, buffering cleverly and so on. Flash has made a very pointed Tweet to say that this is a much better option than performing brute-force traffic-shaping somewhere else in the operator's core or access network. Basically, they are suggesting it's better to compress traffic actively by modifying, rather than force the "natural" content to squeeze through a narrowed pipe.
(The Flash Tweet in full: Nice illustration of watching video with not enough bandwidth, or why bandwidth SHAPING is a DISASTER for online videos http://ow.ly/2upYv)
Of course, the content-optimisation approach to traffic management is not without its flaws either. Firstly, it changes the data transmitted, which is very much the spirit of Internet connectivity. Secondly, it is typically not "bearer-aware", only compressing the traffic if there is actual congestion. Most such solutions are also blind to whether the device is connected via femto or macro networks as well - there is almost no justification for changing content delivered over the user's home broadband and femto.
I don't want to single out Flash here, it's just an example of what I see as an emerging trend for warfare between the various options for traffic management.
Frankly, until we get closer to what I term "holistic traffic management", none of the options will be without problems. There needs to be much more awareness of content, user, network, device, application, actual congestion, pricing/tiering and numerous other criteria in order to make rational and customer-friendly policy decisions.
