Another day, another snipe


Its become an almost daily event recently to wake up and find another blog entry taking a snipe at the work being done by myself and some of the people I work with.  Until now I’d taken a view that I’d prefer to just get on with things but the regularity and persistence of the two bloggers justifies a response.

Finding ways to deliver next generation broadband to UK homes and businesses is hard and it needs the widest possible support and interaction. That means people who haven’t been natural parters in the past are now actively seeking ways to work together to find uncommon solutions to a common problem.

The constant sniping and rumour mongering by what is increasingly being seen as a militant fringe is unhelpful and is more likely to set back the UK’s chances of  seeing widespread investment in next generation broadband services. So long as the voice of communities is seen as a negative attack on others rather than a positive move to find solutions then why would anyone take community broadband seriously?

Ghandi once said something along the lines of  ”be the change you want to see in the world” – prove me and my colleagues wrong by doing something better through positive action but please stop the sniping.

Ask JON to fund it


After a series of blog articles on how the move to a Thinking may impact the way the telecommunications market might be structured I wanted to start to consider how the market might be used to unlock investments and start to build some momentum in the UK so we might realistically consider target inclusion in the 2010/1 to the Home League tables recently posted.

Given the newness of the market idea for telecommunications I fully accept that what follows may be an expression of hope over expectation but it is, I hope, a flow of thought which begins to demonstrate that alternative ways of doing what we’ve always done can begin to unlock new potential. My own philosophy is that when you meet a blockage, first try to remove it; if that’s not possible work around it – never try to work with an obstacle as you’re more likely to compound the problem.

If the traditional broadband operators can’t find a case for investing at a level required by society and the economy then we need to remove the blockages or work around them. What would be damaging would be to accept the blockage as a fact of life and to invest in it. As broadband was deployed the first time around there were local interventions that tried to build confidence in a new market, removing the blocks to investment, and there were others which simply accepted the problem and subsidised network builds. In the former examples, the business case was ultimately made and the long-term cost to the public purse was marginal. The latter, however, tied public funds into sometimes unsustainable projects which only continued as long as the lifeline existed.

The funding requirement for next generation broadband is of an order of magnitude more – its simply not possible to provide small scale funding to prop up a marginal business case and expect high-speed broadband of the kind seen in other countries to appear across the UK. The problem won’t go away by plastering over it and the impact of doing so could make the collapse of the telecoms bubble a decade ago look like a sneeze.

One way of working around the blockage, of finding a new way of doing things, is to use the power of the markets. I first wrote a briefing document on this almost 4 years ago with my colleague Brian Condon but since then we have seen too much turmoil in the financial markets for the similes used then to make it happy reading – but the principles remain true.

When we first considered the shape of a wholesale market for telecommunications the output seemed strange – by simply replacing the occurrences of words like “ducts” with items available in other markets the document made sense. After more time in a dark room with cold towels wrapped around our heads we came to obvious conclusion that it was the structure of the telecoms industry which was wrong and not the concept of an open wholesale market; we’re just so accustomed to a single way of doing things where an incumbent operator and an interventionist regulator dominate the market. But it needn’t be like that.

So how could a wholesale market solve the broadband investment dilemma?

Let’s take the public money currently available for broadband investment. Setting aside any views on whether the 50p tax on phone lines is helpful, I’m assuming for this article its a reality and it will raise something like £150m to 175m each year for the term of the next Government – total fund of up to £1bn. If its spent as a direct injection into broadband infrastructure programmes then the money will achieve very little and the funding will come on stream too slowly to build any momentum  - and perhaps most damagingly there is a real risk that it won’t remove or by-pass the investment obstacles so it may become the prop for a broken business case.

In contrast,  offering the cash to the nascent market as a “future guaranteed order” for access to homes and businesses for the delivery of government services then the fund is being used to help transform the delivery of public services while also providing the telecommunications industry with the certainty it needs to invest. Rather than releasing £150m of funding each year to prop up projects, offer on the new wholesale market an order for VLAN connections to 1,000,000 homes at £10 per month for the next five years in the geographies demanded by public services and which the markets won’t automatically deliver.

By doing this through the marketplace, the funding is targeted to where its needed, with a public audit trail of delivery, and it mandates standards since membership of the market necessitates them. In taking a contract, a network operator will have a guaranteed demand over and above what they might expect from simply offering faster internet connections; something European projects have been able to take to the bank to secure funding. Anchor tenants in the form of housing associations are not unusual in The Netherlands, for example, but this mechanism allows any public services, central or local, to fulfil the same role. The use of the levy in this way is no more than transition funding to provide network builders with a guaranteed tenant and public services like the NHS with access to infrastructure  beyond their current funding streams.

Taking the NHS as the example, they would be able to start offering secure and reliable tele-medicine and independent living technologies enabling people to stay in their homes longer through a nationally agreed framework without additional pressure to them. Imagine adding to the “choose and book” system an option to pick your convalescence after an operation, and opting for “home-based care” automatically provisions a VLAN to your home in parallel to any other services you may have, and by the time you get home the technology is installed and working to help you recover in a more friendly environment and at a lower cost to the public purse.

Similarly in education, enabling the current learning platforms to reach the homes of children through an eGovernment VLAN ensures that that the social impacts of the digital divide are side-stepped while underpinning the safety of our children.

During the transition, public services would need to be remoulded around more flexible delivery of services so that their finances and organisations will be sufficiently restructured  they can pick up the on-going (and reduced) cost of delivering tailored services directly to people.

This kind of approach can’t happen without the existence of a wholesale market for telecommunications with its aggregation points allowing widespread delivery of services over a fragmented patchwork of network infrastructures - but I hope it also begins to shine some light on the benefits of such a fundamental change in the way we do things.

Phrenology of the Thinking Cloud


When I set out to distil my thoughts on a Thinking it looked like three chunks were going to be enough but by the end of it all there were some loose ends still remaining – the combination of a lot to say, a big subject and perhaps the long-form limitations of a blog format. So here I want to draw together a few of the loose ends and attempt to extract some shape and character from the ramblings so far – hence the pseudo-science of phrenology in the title.

The full potential of cloud computing is immense and will be a bigger revolution than the development of the web – of that I have no doubt. Supporting this change is a cloud infrastructure which is also yet to fully develop. Today it really means little more than storage and processing to support relatively simple application within the web but it will begin to draw in more powerful tools like distributed grid computing, parallelism and utility computing – we’ve seen mere hints of this with programmes like SETI and their screen-saver to crunch massive amounts of astronomical data.

As the cloud becomes more conscious with true cognitive powers to rival the memory it has today, the additional requirements will fall on the cloud network. It will no longer be acceptable for the cloud moniker to simply say “I’m so technical you don’t need to know what’s inside” – it will need to take on many of the characteristics of the infrastructure and more importantly the applications also within the cloud. We saw in Part I what this may mean for applications; in Part II we saw that the capability to link the network to applications exists in 3D networking; and in Part III we looked at how the telecommunications market is beginning to change which may unlock some of this power. But I hadn’t really delved into what that might mean as we move to true cloud networks.

Today’s networks are fairly rigid t0 the descriptions we use reinforce this – the superhighway suggesting massive solid routes offering mass transit which took many years to design and build. And this is not so very far from the truth, and this is where the tension lies. Laying -optic cables in the ground requires long-term utility business models with deep pockets while cloud computing is rather more darting and changing, and transitory. The two need to be reconciled if the under-pinning networks are to release the true potential of a thinking cloud. And this creates a problem – the proximity to reality.

Applications people find it easy to shape solutions around people because they have a direct communication; database manager and server people find the conversation not too challenging because they have a good proxy through the developers; network people are several layers down and are trying to manage a necessarily shared domain with competing requirements so its easy to see why telecommunications is seen as some how disconnected from people’s day-to-day reality and not always very supportive.

Networks are like Ogre’s, according to Shrek at least, they are made up of layers. While network engineers may wrestle with a whole stack of layers, commercially we have tended to focus on a very narrow subset which fuses together the rest. The business case for networks has always focussed on the degree of interleaving, or contention, which can be achieved – assume, for example, that only one in five people will be on-line at any one time, and that only one in ten of those are generating traffic at any instant while the rest are reading the web page or email that’s just arrived – so a 50:1 contention ratio works for people who browse the web.

This doesn’t work in a thinking cloud – in fact, it doesn’t really work today as streaming, which necessarily demands a 1:1 contention ratio, and more pervasive computing takes hold. Much smarter, more dynamic measures need to evolve – and quickly. The 3D capabilities of next generation networks provide part of the answer and forge the link between applications and the higher layers of network which will be so critical but it doesn’t address the rather transitory and sometimes sudden demands of bandwidth and routes. New technologies are needed at lower layers which offer the same flexibility we are beginning to see at layer two, through standards like Active Line Access, to will significantly increase the network’s ability to bend and stretch.

Some of these tools are beginning to emerge. Companies like InTune Networks are beginning to release solutions which can do with light what we are beginning to do with virtual networks; wavelengths on demand which are able to respond to the demands of people and the applications they use. In many ways what InTune are creating is “cloud switches” where the switching fabric is dissolved into a cloud of light. Implementing these kinds of tools in the marketplace describe in Part III would unleash wavelengths on demand just as the current plans release VLAN’s on demand. In the future transparent optical cross-connect has the promise of dynamically connecting whole fibres in the way that InTune is able to switch wavelengths. At this point the only rigid element of networks will be the ducts the cables pass through.

As optical technology develops the concept of a cloud network will grow and become more supple. This will result in a network which can morph more easily around people and their demands, and to optimise the capacity at each and every layer. And this in turn means its network managers will be able to sit around the board table and become a constructive part of the business cycle – no longer the group which is too removed from people (not a criticism by the way) and with too many competing demands on their networks to be in a position to offer constructive support.

For countries which get this early the impacts will be huge. New research opportunities in photonics and network design which pioneer new markets; and an economy with much of the rigidity removed, able to draw on the creativity of all its ideas.

European FttH League


Just for clarity, here’s the European FttH league table recently launched at the Lisbon conference:

Note the absence of the UK – it is a requirement to have 1% of homes and businesses connected to fibre-optic networks just to be considered; the model excludes Fibre to the Cabinet which is increasingly a curiously UK preserve.

For the UK to be considered that would mean around 250,000 connections – or around 245,000 more than we did in 2009. The full details can be found at the FttH Council’s website – together with their excellent Business Guide on how to approach a fibre project based on the sober experiences of people who have done it.

The Thinking Cloud – Part III


In Part I, the shape of computing was considered and how the metaphor was perhaps not able to encapsulate the scale of change it may bring. Part II began to explore the impact the may have on broadband services; that the evolution view of next generation broadband is largely wrong and will prevent society from realizing the full potential laid out in Part I. In this chapter, I start to look at how the original internet – the underlying network – will need to change as computing becomes mainstream, and how the telecommunications market will need to reconsider their whole approach.

The first challenge comes from the direction of change. While we are at a point in telecoms history where the technology is fundamentally changing, the real change is coming from society and their use of the Internet. I’ve been criticised before, and no doubt what I about to say will annoy some of my telecoms colleagues further, but the industry to date hasn’t been good at relating to people – at understanding what they want and creating base services moulded around them. To far too many telecos, customers are “revenue generating units” (RGU’s); a necessary source of income but something of an irritation to the smooth running of their expensive network. In Part II we considered this in the ways telecos use traffic shaping to minimise the impact of customers, and in the way the market has opted to differentiate its services by little more than brand.

This time however, the change in telecoms is coinciding with fundamental changes in society and its attitude to technology – it would be a brave (stupid?) company that ignored this as they prepare to invest in the most fundamental and expensive change in their industries long history.

In the UK, like many other countries, the telecoms market is fragmenting. It is no longer certain that a single incumbent operator will be the sole supplier of connections into our homes and businesses as a growing number of organisations using a range of technologies and business models begin to invest in first mile access networks. While its impossible to predict how far this fragmentation will continue, it has become an established fact which creates two key dynamics in the market.

Firstly, at a micro level network owners have to persuade people (not RGU’s) to migrate onto their new, wizzey, and very expensive networks – and that necessitates engaging with customers as never before. Nothing is a substitute for take-up – customers choosing to use your network. But as I demonstrated in Part II, next generation broadband isn’t really about speed – the only message beyond brand typically trumpeted in today’s ISP adverts but this is a message which misses the point of next generation networks.

To further unsettle the existing world order, the necessarily patchwork deployment of next generation networks means global advertising of nationally available services is no longer a viable model. The industry needs to consider how to deliver a differentiated service set which draws on the true characteristics of their next generation broadband networks, which chimes with societies transforming view of technology, and then they need to find ways to share that message at a local level using local channels rather than national media.

There are two quite contrasting international case studies which can be quite informative here:

  • The first is the well known market town of Nuenen near Eindhoven in The Netherlands; this town has achieved immense take-up levels using very smart marketing techniques which are closely tied to the community. They laid out seven pillars for a successful project where perhaps only three of which a traditional network operator can achieve. The key to their success was community communication, an “us feeling” where the community feels engaged, and a local set of services. Nuenen is an example of how to successfully engage with a community, and it can’t be faked.
  • The second example is Slovenia, a country where the incumbent operator has met with very strong competition from a new entrant. The land confiscated by the communists was returned to the Church who no longer needed it. The money the generated from its sale was invested, at the request of parishioners, in next generation broadband but it was the local links which made it a success. No matter how much money the incumbent could invest in their technology and their traditional marketing message, they found it impossible to compete with locally delivered services which people felt related to them in some way.

The lessons from these two are easy to understand but difficult to implement – how can a major, national company truly engage with a community such that they feel engaged? I offer no answers here, although I am working with a number of organisations to develop models which may balance the economic imperative of a top-down model with the requirement to genuinely engage at a local level. With the progress being made, I hope to be able to add some important case studies here soon which show how macro and the micro business approaches can be married.

The second impact of market fragmentation is macro market co-operation. If customers are to see a wide choice of services with some certainty that they will be able to keep them when they move, network owners will need to co-operate. In many cases, they are individually too small and diverse for national service providers to deal with. Even in the case of some of the larger initiatives, major service providers are concerned that the additional value offered by next generation networks may be small when offset against the cost creating an interface to them.

Conceptually, however, this is the easy bit – something other markets have already dealt with long ago. The industry will need a single wholesale market which delivers two things – a series of aggregation points where service providers can expect to find sufficient potential customers, and a trading system which enables service providers, in the widest sense, to buy the wholesale elements they need to build flexible, differentiated services.

When I first started work on this perhaps three years ago the necessary structure looked strange until I did a search, replacing telecoms assets with widgets or cocoa beans. The problem wasn’t with the concepts but with the way we have become used to seeing the telecoms market with a dominant avuncular incumbent.

There are some details which are tricky, like identifying fungible and liquid assets which can be traded but thankfully this is something which can be solved – rather is being solved. Significant elements of the nascent next generation broadband market have come together to create what is being called – the joint operating network. This programme is in the process of turning the discussions within the Broadband Stakeholder Group’s COTS process together with work of standards organisations like the NICC into an open wholesale market for competitive next generation services.

The potential benefits of this move are immense – a vibrant whole sale market which celebrates differentiation and innovation, which provides customers with choice across the “reach-richness” spectrum, and is able  to do this without the need for an interventionist regulator (there will of course still need to a regulator but one adopting a more auditory role).

So while the UK is still unable to be considered for the Global Fibre to the Home League Table because it doesn’t have the minimum market penetration, there are other structural things being put in place which I hope will help the UK not only accelerate its investment in fibre but perhaps more importantly also optimise the benefits of those investments for the industry, the wider economy and for people.

The Thinking Cloud – Part II


In the first bit of my ‘Thinking ’, I tried to consider the shape of computing and what it really means – that perhaps the metaphor was being stretched a little too far. In the second part I regroup onto ground closer to my normal stomping ground, and consider what impact the changes in Part I will have on the underlying infrastructure – how will broadband and the internet need to change to support a “ thinking”.

There is a view that “next generation broadband” is simply an evolution of all that has gone before but I agree with David Brunnen in his recent blog that we aren’t looking at an upgrade – this change is much more fundamental than that.

Ten years ago Evans and Wurster wrote an excellent book, Blown to Bits, looking at some of the reasons the dot.com bubble burst and what strategies could help you survive and prosper. One of the concepts they discuss is how all markets have a trade off between what they call reach and richness – market reach, and the ability to customise and tailor a solution. All businesses sit somewhere along that line with perhaps McDonalds at one end with a global reach bit a low ability to offer you anything other than what’s on their globally fixed menu, and Saville Row tailors at the other end who would find it impossible to become global businesses but can offer you precisely what you want.

Applying this model to telecoms is quite telling – the curve is disjointed, with commodity broadband offerings at one end, then corporate and wholesale products at the other with few if any offering in between.

At the consumer end exists xDSL products where differentiation is limited to little more than brand and contention, while at the other end are wholesale Ethernet products attached to MPLS clouds – and there is almost nothing in between. Not only is this not helpful for customers and large sections of the telecommunications industry, it is no longer necessary – next generation networks have the capability to break this model, if the market environment is allowed to change with it.

Back in the late 1990′s I did some work on what we called then “3D networks” – network technologies have traditionally been 2D with a trade off between geographical reach and speed – dial-up links can cover great distances but at slow speeds, while the new 100 Gbit Ethernet standard over copper looks set to cover just 10m. This was a useful model when considering copper-based networks but is somewhat pointless for networks since there is a variant of every standard from 100 Mbps to 100 Gbps which is able to cover 40km or more with no signs of abating – the research into terabit Ethernet looks likely to follow the same trend. (note the log scale below)

In next generation fibre networks bandwidth is irrelevant.

The third dimension we considered was policy – the ability to tune and shape the environment to support network users. This becomes informative when contrasting existing infrastructure and next generation technologies – setting aside the net neutrality arguments for a moment. With the capability to deliver seemingly endless bandwidth but with a richness previously only available to the wholesale and large corporate markets, next generation broadband offerings fundamentally change the shape of the market.

The NICC is currently formalising the Active Line Ethernet standard for networks – this will have at its core requirements to deliver at least four VLAN’s to each customer, currently each with five qualities of service. This shifts broadband environments from monochromatic to having 20 colours in a spectrum. With distance as a barrier removed – the broadband market will never be the same again.

How does this affect “cloud thinking”?

Today’s internet can be a pretty hostile environment for applications. So before we go any further let me tackle the net neutrality debate head on. There is an interesting difference in sentiments between users of corporate networks and the internet. In the corporate world finely tuned 3D networks are a good thing – they ensure applications run optimally and the business runs smoothly. On the internet, traffic shaping is seen a severe curtailment and fundamentally wrong. Why?

Because internet service providers use policy-networking techniques to minimise the impact their customer have on their expensive networks. This is fundamentally bad and I fall 100% behind the supporters of net neutrality – today.

However, there is a fundamental difference in NGA, or at least the way the UK is approaching it. With at least four VLAN’s, your ISP can’t monopolise your access to the IP world – you have choice. Today if a media company is as unhappy as you are about the way their video streams are tuned down, there is very little they can do about it – in an NGA world, they can simply choose to by-pass the internet.

And this will happen – the world of service providers is about to become a whole lot richer – it will no longer be synonymous with internet service providers. They will be joined by games service providers, healthcare service providers, and a whole raft of others.

How do I know this isn’t just a pipe dream? Content delivery networks (CDN’s) are rapidly becoming the biggest international transit companies, over taking many traditional internet transit companies. The customers of CDN’s are the same media and cloud computing companies that are impacted by today’s ISP policies. These companies are seeing their brand value tarnished and their business opportunities curtailed – if they could bypass the internet and form a relationship with you directly they would. NGA networks allow them.

So just as we start to consider a thinking cloud, we can also begin to consider a network environment able to support and nurture it. In the past, the network architect was often the expensive nay-sayer – with bandwidth no longer a barrier and networks able to be conscious of users and their applications, in this world network architects will become an essential part of the creative process.

In the next part I start to explore what happens within the original cloud as we see it soften its edges and become more nebulous and adaptable.
