Radical Simplicity: Moving Mountains for Personalized Services

Monday, January 16th, 2012 by Cam Cullen

Steve Jobs once said, “That’s been one of my mantras – focus and simplicity. Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it’s worth it in the end because once you get there, you can move mountains.”

There are three pillars to Intelligent Policy Enforcement: Awareness, Analysis, and Control. Solutions that lack any of these capabilities will limit the ability of an operator to deliver personalized services to their customers. The more they lack, the more limitations that will be imposed on the operator – whether those limits are scalability, performance, granularity, or even operational in nature.

Let’s be upfront about something: Personalized services are HARD.

Think of all the pieces that have to fall into place to deliver a personalized service.

1) A subscriber activates their device, and attempts to access the network. The network authenticates the subscriber and/or device to ensure that they are allowed access to the network.

2) Subscriber “service” must be determined and provisioned to the network. The service “attributes” may include bandwidth allowed, volume of data (either bulk or per service), priorities, security filters, value-added services, or even multi-device correlations. Depending on how the network is configured, this provisioning could be a single transaction to a single system, or many transactions to many systems (policy, charging, access, etc.). The subscriber and their data traffic must be associated with whatever “attributes” that are necessary to deliver their purchased service to their devices.

3) The systems that have been provisioned with the service “attributes” must enforce those attributes without causing instability of the systems or requiring additional CAPEX due to “unexpected” scalability issues.

4) The systems must perform network and business intelligence gathering on all traffic to feed the analytics systems for future service development. The more information that can be collected, the more valuable the data is for the operator. This data has to be collected with as small of an interval as possible, as the longer the interval the more you lose granularity (for example spikes in bandwidth and latency can be smoothed out over long intervals)

5) If volume/event-based charging or CDR/UDR generation is required, every charging event can result in a transaction with the charging infrastructure, and especially at session closing time.

6) In a network where phones go into an “idle” mode or where subscriber movement between locations is tracked, every time this happens can result in more transactions.

And the more services you offer, the harder it gets…

With the announcement of our PL20000 today, we believe that we have delivered the final piece of the puzzle for an ecosystem that will enable the largest network operators in the world to compete on an even keel with smaller, more agile network operators. The limitations faced by large operators are focused on scalability and complexity. Scalability is now a moot point, as the PL20000 can meet the needs of even the most stressful network deployments with the massive performance increase and the port density/support for 100GE interfaces.

The “Simplicity” part is harder (hence the title of the blog). We have been adding capabilities for the last few years to make service creation simpler for operators. Report Studio is a perfect example of this – operators can now ask questions of the network staff and the network team can use Report Studio to answer them based on the massive statistics repository available in the PacketLogic Intelligence Center (which handles an order of magnitude more statistics than other solutions). Our Virtual Services Capability enables operators to define their own services based on application properties (URLs, http referrers, content-type, device-types, file-type, etc.) without intervention by Procera or our signature development team. We have unmatched capability with our PacketLogic Subscriber Management system – in terms of performance (over 100,000 transactions per second), capacity (up to 20,000,000 subscribers in a single system), and ease-of-use (customizable service dictionaries, easy to use interface, interfaces to multiple policy and charging systems simultaneously).

We believe that we are driving solutions towards the nirvana of ‘Radical Simplicity” where carrier-grade IPE solutions do not have to be managed by acolytes of technology that speak arcane languages (ok, maybe program arcane languages). The combination of performance, scalability, and ease-of-use will take Intelligent Policy Enforcement to mass-market deployments for operators of all sizes. Operators that are forced to wait 9 months for a service launch to capitalize on a new trend will find that the trend is no longer hot. Operators that must plan for a performance or scalability reduction for every new service that they launch will very quickly find their solutions very capital intensive and inefficient.

Simplicity is hard. We want to help you move mountains, so we are working smarter (as well as harder!).

BBTM in London – The Buffet Is Closed!

Thursday, November 17th, 2011 by Jon Linden

I just got back from London and Informa’s third annual global Broadband Traffic Management (BBTM) conference, and guess what, the buffet is closed! Not the actual buffet at the conference, which in spite today’s state of the global economy, was bigger and tastier than ever – great job Royal Garden Hotel! No, I’m talking about the “all you can eat” broadband offering that used to be standard, that has become rare, and that was predicted dead in the coming year or two.

I love the crowded and intimate exhibition and networking area at BBTM where competitors and partners rub shoulders as they work hard to convince operator representatives about the uniqueness of their products. What I love even more, is when there’s an opportunity to debate hot topics with an audience.

So, I was full of expectation as I walked over to the Kensington Suite fifteen minutes ahead of the session to grab a seat at the podium. Soon I was joined by my fellow panelists from Mu (operator in UAE), Belgacom, Sandvine, Allot and Tekelec; and last but not least, our moderator for the day, Steven Hartley from Ovum.

The topic for the day was “Can Operators Manage the Transition Away From Unlimited Plans While Keeping Customers Happy?”, and the unanimous verdict was that unlimited “all you can eat” broadband offerings are doomed due to the disconnect between the income and the cost of producing them. But what will come in its place, and what are things to consider as operators head in this direction? Let me summarize my favorite parts of the panel discussion for those of you who didn’t have the opportunity to attend on-site:

  • The key is to package and communicate offers that are understandable. We’ve made bandwidth (speed) and volume (caps) industry standard for service tiers. Both of which are insanely bad – they’re introvert (cost-based), tech terms, and we can’t even guarantee a firm speed but a “best effort up to” number. And they’re not common knowledge since the majority of the population is not a computer engineer and familiar with gigabytes and gigabits – and they don’t understand the difference – which means that we must waste energy educating them. And we, the specialists, can’t even answer the most basic question, “what can I do with 5 Mbps that I can’t do with 2?”
  • Instead you should sell value-based offers. The difference in tiers should present a clear value to the customer. By making the benefits understandable and measurable, you manage expectation – and disappointment is always a question of expectation.
  • For example, if you use Facebook 90% of the time, you will be a happy customer if you have a perceived good user-experience when using Facebook, i.e. 90% of the time you use the service. And you will not have high expectations for the other 10% since that’s not what you primarily pay for. You might even be happily surprised just by the fact that it works. User experience is not a question of size, or speed in this case, just like restaurants don’t promote the size of the meal on the á la carte menu.
  • 3UK, who offer an unlimited data plan, attended the session from row one. I love what 3UK do because it’s extremely easy to understand – unlimited data traffic on your smartphone. As a consumer I find this very appealing. Anyone can understand this. But it’s an example of an “unlimited with restrictions” since it’s tied to one specific device.
  • This is also a good example of the constant change operators must embrace. The border between smartphones and computers will disappear, and the smartphone will be as bandwidth consuming as a laptop. By then the package must be redefined. But that’s fine. You will not package the eternal service package anymore since there are variables you can’t control. The “youth package” might push Facebook today, Spotify six months from now, and an application not yet developed in a year.
  • This makes the soft values like customer loyalty and a strong brand extremely crucial. You must create an Apple-like experience and relationship with your customers. The customers are probably Apple’s best sales team, and they associated themselves so much with the product that it becomes a lifestyle. In the broadband world this would be a service that the customer perceives as “good for his purposes”, at the right price, and he’ll actively argue for why he picked this service when talking to his friends.
  • Another Apple (for Apple) comparison is their ability to sell customers more and more Apple products – iPhone, MacBook, iPad and an AppleTV – that are interconnected. This is how you should sell services to your customers. And it’s also applicable to these specific Apple products since consumers don’t want an individual plan for each of the four, five IP-based devices they carry around. The plan might even extend itself to a group – a family, a company or a soccer team.

Even though we as consumers consider restriction to unlimited as something bad, I think that we all understand that there must be an underlying business rational. The quality of the buffet is rarely as good as the á la carte, or we would eat at the buffet all the time. As we change to accommodate today’s conditions, we might as well adjust so that it becomes understandable – even for laymen – and measurable so it can meet our expectations.

Time for lunch. The buffet is served. Enjoy it while you can!

Do’s and Don’ts in Bandwidth Control

Wednesday, December 2nd, 2009 by Jon Linden

Suddenly it all happens at once. We went from zero to two events focused on DPI in one week – Light Reading’s virtual tradeshow Policy Control & Deep Packet Inspection, and Informa’s Broadband Traffic Management event IRL in London early last week. These events are good validation that DPI has grown up to get proper attention.

I was on-site at the event in London – and I apologies for the hotel lobby background noise on my line in the LR panel discussion. But I also had the pleasure to be on a panel in London together with Benny Lim from SingTel and David Hodgers from O2 Ireland, moderated by Mark Newman from Informa. The topic was “Lessons Learnt: The Do’s and Don’ts of Bandwidth Control”.

So what are the lessons learnt on bandwidth control? Let me quickly go through my conclusions and what I told the audience. When looking at do’s and don’ts I see two categories: what works and what ‘s ethical. The latter is more challenging with today’s fast moving social media where bad news travels fast and subscribers vote with their feet.

How do you manage this? Well, don’t expect to “get away with it”. Internet users are savvy and operators in London confirmed that non-transparency came back to bite them. You must be able to defend what you’re doing, and a good test is if you’d accept it yourself. Greed is not an acceptable reason, though a viable business case normally is.

Do’s and don’ts also depend on what you’re trying to achieve. DPI and bandwidth control spans over a broad range of applications, from network protection and congestion control to quality assurance and service differentiation. We tend to be very introvert and technology-driven in this industry, but you must start from business benefits and objectives in order to define intentions and make it understandable to your end-users.

The key to what works is knowing what’s going on. It’s not an option to guess what your customers do and how your network is doing. And conditions change – all the time. What used to be 80% filesharing a year and a half ago is today replaced with 40% streaming video as the largest bandwidth consumer. A policy rule-set that is not up-to-date will cause some strange consequences.

I wish I could provide a blueprint for what works, but every situation is unique. Your product mix, fixed and/or mobile, target groups, price positioning, and on top of this there are geographical differences like what applications are used and what bandwidth control practices are accepted.

This means that the number one thing to do is try. You will have to try it out and assess the outcome in your specific situation and your environment. I know this sound scary, but be adaptive, be quick, and make sure you make qualified decisions based on facts rather than guesstimates and assumptions.

Let me also summarize my don’ts: Don’t lie – be transparent. Don’t insert packets – honor integrity. Don’t get introverted and super techie – understand your business and your customers. And don’t do nothing – this is the most expensive decision of them all…

Let me wrap up with one more suggestion for what you should do: Keep it simple! Complexity kills this cat. If it’s too complicated you won’t be able to communicate to your subscribers, it’ll be impossible to update and change, and you won’t be able to measure if you successfully achieved what you intended to. This is hard to make simple – which is why we, Procera, are here to help ;-)
