PacketLogic Report Studio: Information is Cheap, Lack of Knowledge is Expensive

Monday, November 14th, 2011 by Cam Cullen

I was reading an interview with George Dyson, and during the interview, he made a comment that really caught my attention. He was speaking of the volumes of data that many people have to deal with, and his comment was “Information is cheap, meaning is expensive”. The comment resonated for me, as it encapsulated the headline of a new product from Procera called PacketLogicTM Report Studio.

Two of the biggest challenges that network operators face is 1) information overload, and 2) lack of relevant information. There are plenty of Internet trends reports that can tell you what is happening on networks around the world, but NONE of them tell you what is really happening on your network. Most Intelligent Policy Enforcement solutions can generate many canned reports, and even place them on pretty web pages, but they are all statically configured templates and reports. Most network operators can tell you down to the byte how much traffic is on their network, but that information does not allow you to plan new service offerings. It can also mislead you into thinking that you need to add more capacity to your network, but it may be that the excess bandwidth is being taken up by applications that you should not spend money to enable.

A perfect example of this is the recent push for “Facebook for Free” plans. This is a great marketing plan, as it resonates with the “hyper-connected” crowd. However, in studies that we have done in North America, operators considering Facebook for Free plans should know that Facebook sites have 5x the number of connections AND incoming traffic and users spend as much as 10x active time on Facebook in a day than the next most popular site. For a fixed line operator, this is probably not a big issue. For a mobile operator, it means that the subscriber will be connected for a far longer time to their network (dramatically increasing the attach percentage for the subscriber), and using almost as much bandwidth as streaming video sites. Although this still may be a great service offering, the operator needs to be able to evaluate the business and technical issues with this service specific to their business model – based on the ACTUAL devices, locations, and service plans that they have in use in their network (not a canned report based on industry averages).

PacketLogic Report Studio is a leap forward in that it allows operators to easily create these reports with the fine-grained information that is available to them with the PacketLogic Solution. I recently contributed an article to Wireless Week at http://www.wirelessweek.com/Articles/2011/11/Technology-Darwinism-Goes-Mobile-Wireless-Networks/, and the concluding line for the report sums up nicely what I think the issue for network operators is going forward.

“Mobile operators that lack this knowledge will struggle to launch new services. They will become followers, not industry leaders. In a market where only the strong survive and the rest of the players are consumed, not using business-ready network intelligence will put a mobile operator at risk of being the modern day equivalent of the dodo.”

Device Awareness: The Key to Service Planning

Thursday, July 22nd, 2010 by Cam Cullen

Recently there has been a lot of talk among DPI vendors about location awareness. Location awareness is critical to understanding where the bottlenecks on your network occur, and giving you the ability to actively manage traffic in those locations. Although this is a key capability of what Procera offers (and in much more depth than many other vendors), I want to focus on another key “awareness” component that is not often talked about that can vastly improve the capability of an operator to plan their capacity upgrades and pricing plans.

What is device awareness? Simply put, device awareness is the ability of the DPI system to understand what device is sending/requesting traffic on the network. With so many “internet-connected” devices on networks today, the variety of places and formats to access data has exploded. You can watch Netflix on many TVs, DVD or Blu-Ray players, dedicated boxes (like Roku), consoles (PS3, Wii, and Xbox), smartphones, tablets, or your PC, and Hulu on many of the same.

Why is device awareness important? Understanding what devices your users have connected to the network helps an operator to understand the potential impact of several different scenarios:

1)     If I have x users with a certain device on my networks with a certain location bias and usage profile, what happens if that number becomes 2x?

2)     If a new application comes out (say for example Netflix for PS3, or Hulu Plus for PS3), and I have x users with that device, what is my exposure if 20% of my users start using the new application?

3)     If I want to launch a service with a new device (new iPhone or Android device) and other operators have announced that the normal usage profile for that device is 200GB/month, what might happen to my network with an aggressive take rate?

For Product and Marketing planners, being able to answer these types of questions ensures that the network can handle any changes in user behavior – either application or device related. For users, it ensures that the network can adapt to their usage and not experience dissatisfaction with network performance as usage patterns morph over time. All operators are very aware of the user dissatisfaction issues floating around the world as Smartphone and mobile broadband laptop connections become mission critical for corporations. Proactive management and planning are possible with the right kind of awareness and reporting engines.

How is device awareness implemented?  There are many ways that this can be gathered on the network. In mobile networks, it is common for operators to include this information in the Business or Operational Support Systems for each user account, and often make it part of the user authentication and accounting exchange where it can be snooped by a DPI system. It can also be determined by the applications used by the subscriber (i.e. if the traffic matches Rock Band for the PS3, the user is most likely using a PS3). Another method is by information gleaned from the user agent or application specific information that can be gathered by the DPI engine during Layer 7 analysis. Although each of these methods is not a fail-safe method to gather device information, the combination of these methods can provide a very close approximation for network operators. For example, a query on how many unique subscribers matched a PS3 signature during the month could provide the basis for determining how many subscribers would have access to the new Hulu Plus video streaming application when it was released for the PS3, and another query to see how many of those subscribers had used Hulu (or any streaming video service) before would provide additional planning input to determine the impact of that new service on their network.

Device awareness is a key aspect of the “Awareness” capability of the Procera solution, and without awareness, analysis and control are not possible. I will have more to say on location awareness in a future blog, as this is another key awareness factor, not only for mobile networks, but also for fixed and wi-fi deployments as well. As devices proliferate, being able to ensure that the content is served appropriately for those devices and ensure the correct amount of bandwidth is available will be critical.
