Taking PacketLogic to School…

Tuesday, March 29th, 2011 by Cam Cullen

Over the past twelve months, Procera has experienced great successes in the Higher Education market across the globe. Although there are a number of contributing factors to this achievement, a few reasons have really begun to stand out in our minds as to why we have been so successful in this space.

Higher Education institutions around the world have quickly realized that their networks are a critical component in their success, ensuring that the bandwidth is managed properly and that the students have access to the resources that they need to succeed in the classroom is critical. The cost of this bandwidth can quickly spiral out of control, as students will use every bit of available bandwidth – “Just because it is there”. Since all applications do not have the same performance or latency requirements from the network, it makes sense to ensure that real-time applications (VOIP, conferencing, video, etc.) have the necessary bandwidth needed to operate effectively, and congestion on the Internet link is very common. The available bandwidth to universities has dramatically increased over the past few years, to the point where many require not just 1Gbps of network performance, but even up to 10Gbps of capacity of traffic management, and they have outgrown their existing traffic management solutions.

In the United States, there is even a mandate called the Higher Education Opportunity Act (HEOA) that instructs Higher Education institutions to take action to help control illegal file sharing. Procera has helped many higher education institutions comply with the HEOA by helping them effectively combat the unauthorized distribution of copyrighted materials by allowing them to control the use of file sharing technologies on their network – typically a huge contributor to network congestion and bandwidth usage. It has also saved many University CIOs from receiving letters from the MPAA and RIAA about the copyright violations occurring on their network, not to mention helped pare back their overhead by reducing the number of DMCA take-down notices they receive

From our perspective, Higher Education institutions are the breeding ground for new and exciting applications. Being installed in as many of these networks as possible keeps us at the forefront of application trends, as we have seen the use of streaming video, social networking applications, and VOIP/IM applications from around the world skyrocket in these environments, and they continue to keep our signature database ahead of competitors that do not have the same exposure and responsiveness to the Higher Education customer base. We have also benefited from these customers’ deployments as they are often more sophisticated in their use of policies to control bandwidth than even some service providers, so they give PacketLogic a good workout and ensure that our solutions maintain performance and visibility under even heavy loads. We have also experienced good feedback on our implementations of IPv6, which are becoming more and more critical to research universities and international consortiums, as IPv6 has become more prevalent on Internet2 links. We strongly believe that IPv6 will become more critical to networks around the world, and are working to provide the leading IPv6-aware traffic management solution on the market.

Besides, how can you have an “Intelligent” enforcement solution without going to school every once in awhile? We learn something new every day at Procera, and it is often our education customers that teach us that lesson.

Mobile World Congress…It is all about the Apps!

Thursday, February 18th, 2010 by Cam Cullen

I have spent the week in Barcelona attending the Mobile World Congress event. Anyone that thinks that there is no vibrancy in the networking world should have been here to see the show. The halls were packed, the booths were busy, and the meeting rooms fully booked. There is a lot of excitement about where the mobile industry is going, and the opportunity that exists for mobile providers going forward.

One thing that jumped out at me during the show was the growing focus on the applications that are driving mobile usage. Yes, there was plenty of LTE hype, and lots of platform and operating system buzz (you should have seen the line for the Android developers lab as well as the push Microsoft made for Windows 7 Mobile), but focus seems to be shifting towards the applications that are driving mobile usage. The operators are keen on pushing new applications, because they will drive up data usage and increase the urge for users to upgrade their devices and service packages.

There is a clear recognition that mobile success may be won or lost on the application front. In the US, Apple has done a good job with marketing the iPhone by focusing on the everyday things that it can do to make your life easier with mobility (finding restaurants, checking on movie showtimes, etc). Google did a great ad during the SuperBowl (American Football for those outside the US) that showed Google search used to progress a storyline for a person’s life (http://www.youtube.com/watch?v=nnsSUqgkDwU) which is not specifically targeted at Android, but can be applied to Android and mobility. Microsoft was showing the same type of applications and integration at MWC as part of their booth show. Ericsson announced an applications store (eStore) with more than 30,000 applications that carriers can offer those apps to their own customers.  A new alliance was formed between 24 operators (including ATT, China Mobile, Orange, etc) called the Wholesale Applications Community (WAC) designed to simplify how application vendors get their applications to the end user.

Why is this important to a DPI vendor? Mobile operators who want to understand what applications are clicking with their users need to look no further than to a “robust” DPI system to understand what applications, clients, and software their users are running – even down to the device level. Application vendors obviously want the operators to know that their application is popular, since it will open up more opportunities to sell that application, whether it is through the operators own application store or the mobile OS store (iTunes, Android market, etc). The DPI “lite” solutions provided by some vendors will never keep pace with the ability of a dedicated DPI solution. At Procera, application recognition has always been a core element of our solution, we release updates every two weeks to keep pace with the new applications our customers encounter in the wild, and this includes mobile applications.

The applications that really jumped out at me are the “useful” applications that can simplify or make life easier for people. Simple navigation capabilities can be helpful even if you are walking through a large city – looking for a specific location for a meeting, searching for a restaurant, looking for a store. VOIP applications (which are finally being approved for mobile use by some operators) can be cheaper than international calls in some instances (or using the VOIP over wi-fi is even better). Even bar-code scanners that allow instant internet price comparisons are really useful if you are shopping and want to make sure you are getting a better deal.

As mobile operators look to understand what they need to do to generate revenue, I am certain that going forward, applications will be a big part of that plan – whether it is enabling some of the applications in real-time (even if it is not sold by the operator – like GPS), or form a retail perspective in their application stores. DPI can help them understand where their greatest opportunities are – and will allow them to service their customers better by meeting their expectations.

Is Accuracy Really That Important?

Wednesday, December 2nd, 2009 by Jon Linden

Trust me, it is. There are a lot of good reasons why we promote “accuracy and control, redefined” in our logo. Ask any operator with DPI experience, and you’ll hear that accuracy is top of the list. And we can, in all honesty, say that DPI didn’t really deliver on this promise originally. The first generation of DPI identified port-hoping filesharing applications good enough to cap them to avoid disaster.

But times have changed. Today we have very sophisticated tools in our bag and our traffic identification engine looks at several criteria when determining what application each individual connection is. We also leverage characteristics, like interactive, streaming, download and bulky to categorize traffic in an application-agnostic fashion.

Online applications have evolved extensively over the years I’ve been working with DPI. Back in the days when IP and TCP were invented, all traffic was client-server-based. The applications were neither time nor quality sensitive, but everyone was happy with a global and resilient network.

Fast forward to today. P2P technology is used to leverage bandwidth and CPU capacity at the edge of the network for faster connectivity and to decrease the traffic being sent over the core network. P2P technology is used by the streaming music services we run all day at the office, as well as the online HD video on demand service we use at home at night. Both Salesforce.com and our office phones run over IP enabling us to work from home as if we were at the office. But we would also be totally paralized if the Internet connection (as well as the redundant link ;-) ) was down. This is how crucial and integrated the Internet is in our lives today, and this is why traffic volumes grow at a pace that outdoes Moore’s law and that saturates pipes.

Of course, these applications are totally different in nature and have different requirements for how to be treated to function properly. Of course, different users have different expectations in different situations at different times of day. Of course, it would be an issue if you treat HD video as filesharing or World of Warcraft as SIP. This will impact the performance of the network, but also your ability to manage expectations and create viable business cases for how to satisfy different user profiles. Step one in any process is analysis, and unless you trust the intelligence you use for your analysis you won’t dare to make decisions based on these facts.

So, this is one of these cases where good enough isn’t good enough. Trust me when I say that you will want to trust the information you have at hand when you make critical decisions.
