“PacketLogic is now available with gigabit interfaces!” This is not today’s announcement, but it’s also not ancient history. We launched the second generation of PacketLogic with (almost) gigabit capacity in April 2004. Four years later, in May of 2008, we released our high-end PL10000 family with 10G interfaces and what is still the highest capacity of any DPI system available in the market today.

What I’m saying is that we love breaking speed records. Now we’re doing it again; but in a very different way. The new PacketLogic PL8720 is the first 10 Gbps DPI system that comes in a slick, real estate and power efficient 2RU appliance with the market’s highest port-density per rack unit. Most importantly, it’s cost efficient. Read more [+]

The very nature of predictions is that they can be wrong. But sometimes they’re more substantiated, sometimes the source is more credible, and sometimes you just want them to be true. The former two apply to Deloitte Touche Tohmatsu’s “Telecommunications Predictions” that I read every year. When they predict, for this year, a 100% growth for products that help decongest the mobile bottleneck, then I also confess to wish for them to be true.

While over-all mobile operator spending is expected to grow 7% in 2010, some pockets of technology – where one of the first segments they point out is deep packet inspection (DPI) – can grow more than 10x thanks to a pressing need. In 2009 the last walled gardens were torn down, smart phones became data smart, user interfaces encouraged use of data services, and 3G connections became a true option to fixed broadband (I use it as such at my summer home and when travelling). Data volume has grown and will continue to grow accordingly. Read more [+]

Sorry, there should be a question mark at the end of that heading, and the answer is No!  The fact is you need to invest in DPI now. I know I’m biased, but that’s why I possess hands-on knowledge and facts of what our customers do and why.

DPI does not equal P2P throttling and Net Neutrality infringement. P2P control originally presented itself as an opportunity for DPI with a quick ROI on a hair-on-fire issue where P2P filesharing rampaged at an exponential growth rate, which meant exponential cost. But today we’re in the second, or I would even argue the third generation of DPI, and both products, and the use of these products, have evolved and become much more sophisticated. Read more [+]

The rumor is true, DPI and Policy Control are confirmed to be a couple and have been seen hand-in-hand even in public recently. Feelings are mutual and this is bound to last “until death do us part”.

The 3GPP framework rules! At least in the mobile space and it’s also making headway into fixed. That’s good. DPI has become a critical component in a service provider network, which requires DPI to interact with surrounding systems. On top of this complexity grows with tiered services, volume quotas, sponsored sites, and premium gaming and telecommuter services.

This is where the policy server, or PCRF (Policy Charging and Rules Function), comes in.  DPI is an excellent traffic analyzer and policy enforcer. But since DPI in most cases resides inline and manages large volumes of traffic, it can’t afford  “wasting” cycles on polling information from other systems and correlating a lot of conditions.

Every New Year’s Eve, half an hour before midnight, Swedish television airs a traditional black and white TV episode called the ”The countess and the servant”. The table is set for a party of six, but none of the guests are present. The countess sits at the head of the table and the servant acts the role of each of the guests, toasting five times a dish, quickly getting more and more drunk, stumbling over the head of a bear that decorates the floor.

The financial climate has been one big stumble in a bear market in 2009. Operators and telcos have not been suffering as badly as many other industries – mainly due to two steel baths already endured since the turn of the millennium – and have continued to invest, though the decision has transitioned from the CTO’s to the CFO’s office, adding another layer of involvement and delays to the process. The cutthroat nature of the financial climate has put strain on all vendors, but it strengthens the ones who survive since it requires a compelling offer, obvious value, and a sustainable business model. We all come stronger out of this. Read more [+]
