DPI – We’ve got an app for that!

Thursday, May 20th, 2010 by Cam Cullen

As you can tell from my past blogs, I am a bit manic about devices and applications. The new business models created out of thin air by Apple – starting with iTunes, carrying forward with the iPhone, and now the iPad – have either saved or revitalized the music industry, small application/game developers, and the mobile handset market. There have a been a number of articles written on these topics, so I won’t dwell on it, but I think it is fair to say that entirely new options exist for innovation and revenue now that these products are on the market. They also inspired other vendors to attempt to compete with Apple, and the overall market for similar devices has grown as a result (the size of the smartphone market alone has grown at astounding rates).

What does this have to do with DPI? In the past, DPI was used to manage traffic (Peer-to-Peer mainly) and to provide visibility into what was happening on your network.

But this is not your father’s DPI …

With the advent of subscriber management for DPI systems, network operators have an entire new universe of possibilities on how to use DPI. We have operators around the world that have come up with very clever uses of DPI that enable them to operate their networks more efficiently, comply with regulatory mandates by governments, or generate additional revenue. It has also allowed them to create new types of service plans, not only ones that cost more money for subscribers, but also ones that SAVE money for subscribers.

A perfect example of this might be a service plan that voluntarily restricts the bandwidth for file sharing or video streaming in exchange for a lower monthly fee. A provider could offer this plan for potentially half (or less) the cost of a normal plan, because that user would introduce a much lower load on the network than a “normal” user.

Another hot topic is flat rate plans versus usage based plans, with some users being extremely vocal and speaking with their wallets. Why not combine the two? Offer a flat rate for web browsing and email, but usage-based pricing for streaming video or file sharing? This would increase the overall market for data services, as more casual users would be willing to purchase these data plans versus being afraid of the big leap in price for an “unlimited” data plan. This could even be extended between mobile service providers for reduced data fees for roaming – a huge sore spot for smartphone and data users that travel internationally.

An interesting application is the ability to offer multiple services simultaneously for each subscriber. Hmmm….what exactly does that mean? What if a subscriber wants a Parental control service, a managed security service, and to take advantage of a video caching service all at the same time? In most current network architectures this is not easily achievable – especially if the decision is made per-subscriber and per-application (i.e. Parental Control only on web browsing, video caching only on streaming video, and email to the virus scanner). DPI understand both applications and subscribers, and can effectively re-direct traffic as needed to the correct service (and even load balance between the servers!) – vastly simplifying the network operations, and enabling a service combination that is not possible today for operators.

We love it when our customers bring us new ideas. More than one customer has taken a look at what capabilities we have inside our LiewView application and came up with an entirely new idea for a service plan or a new network report that directly led them to a new service offering since they can better understand how their subscribers are using the network.

Got any ideas?
