Chicken or Egg – Broadband or PSN?


As Local Authorities around the country are beginning to scramble to prepare for the competitions, a question seems to be hanging over everyone and is largely going unanswered: Which comes first – the PSN or the ?

A good number of local authorities are rolling their internal networking needs into the wider infrastructure project, which is tending to result in a PSN process leading the strategy and a fairly traditional ensuing. But its not clear to me that this is always the best approach.

Certainly the public sector is normally one of the biggest customers of broadband in any geography, and knowing that there is a willing anchor tenant certainly improves the business case but using the PSN as the basis for the procurement isn’t quite the same thing – the combined weight of the SME and consumer markets are considerably larger than the combined weight of the public sector, so procuring the network in the image of the smaller stakeholder doesn’t seem to make sense.

The case for broadband infrastructure can be made with or without the immediate custom of the public sector, while the existence of a next generation infrastructure will certainly make the procurement of a PSN easier and more powerful. Adding the promise of public sector business alongside that of local businesses and domestic customers helps the case – it doesn’t make it alone.

So if the public sector is seen as one of the stakeholders rather than the lead, how does this change the approach?

For any number of reasons, the procurement of a PSN means a traditional procurement exercise with a single county-wide winner. There is a relatively small pool of possible winners, all from the more traditional end of the market – it would be unlikely that Rutland Telecom or Vtesse, for example, would seriously consider bidding for a PSN contract, yet they are two of the most innovative network operators in the UK today and have demonstrated their ability to provide the kind of platform on which a flexible and high-speed PSN might be based.

Each locality will need to adopt its own approach, reflecting local needs and opportunities, as it prepares to bid for BD-UK cash. This may, in some areas, lead to a single big contract being awarded but its not the only approach, and its not one that easily meets the diverse needs of many geographies.

A more nuanced approach is likely to lead to some kind of framework, made up of a variety of providers coming together with a diverse set of stakeholders, each with their own needs and capabilities.

One such approach might adopt the LEP process, with  communities or parishes that naturally associate with each other joining forces as combined elements in a county-wide framework.

  • Some of these areas will have money to invest;
  • Some may be happy to sign pre-orders as collateral;
  • Some will dig the trenches;
  • While others will race for infinity.

Such a framework will attract a wider range of bidders, greater scope for investment, and a more creative solution able to optimise every inch of every county.

A PSN built on such a rich and diverse infrastructure, based on known and existing standards, will generate a greater scope for service transformation and the development of stronger partnerships with local people and businesses.

For me, the broadband comes first – the PSN is one of its anchors.

Ken Olsen


I’ve often felt that the of computing would make a fascinating topic for the TV – the impact of its short life so far can’t be underestimated yet many people have no idea who the pioneers are who made it all possible. One of two name have entered public consciousness, Bill Gates and Steve Jobs, but so many remain the heroes of the geeks alone.

One of those heroes was Ken Olsen who died this week; the founder of DEC, a company whose legacy is far greater than their commercial success.

The PDP mini-computers he created were the tools of choice for innovators in the 60′s and 70′s. Unix and C were created on PDPs, and the ARPAnet and formed around them; you can still see them in action at the Bletchley Park Museum of Computing running air traffic control and, if you’re lucky, chess on a line-printer terminal.

More than 30 years ago he was one of the first to see the potential of Ethernet, initially called DIX Ethernet for Digital (DEC), Intel and Xerox – as we face the shift to , its worth remembering the vision and determination of people like Ken Olsen who made it possible.

Homework: read the ALA documents


I received an email this week from the NICC’s Ethernet Working Group with links to the finalised Active Line Access (ALA) document. This is very exciting for all sorts of reasons.

ALA is the industry agreed model designed specifically for the next generation world, and at any number of levels it fundamentally changes the way will work in the the UK.

The documents are not an easy read (this is, after all, a set of engineering standards designed to be implemented by engineers) but its impact should be understood by everyone who has an opinion on the future shape of broadband, the or .

I attended some of the early meetings as an observer and because, like any opinionated techy, I wanted to help shape some of the early aspects. The Ethernet Working Group under Chris Gallon’s chairmanship is something of a technical dream team – they are the deeply technical architects and engineers from the major vendors and key network operators tasked with working out how their organisations can interoperate.

The work they have done is undoubtedly impressive – they have taken diverse standards from the Broadband Forum, the Metro Ethernet Forum and other standards bodies from around the world and carefully and creatively sewn them together into a single framework which unlocks the potential of next generation broadband across a wide range or network architectures and technologies.

Whether you opt for , point to point ethernet or VDSL from a cabinet, ALA works and can hand over a connection in a seamless and universally consistent way to a service provider. And I see few reasons why it wouldn’t also work for many wireless technologies based around Ethernet and supporting VLAN’s.

Now this brilliant piece of work is published, we have a duty to understand what is possible and to start to consider what is desirable. It is no longer reasonable to opine on net neutrality or the future of the internet without properly appreciating the impact of this work.

If you are a , commercial organisation or public body thinking of building a network under the framework you will need to be open access – by law – and that means you need to understand ALA – no if, no buts.

So before you say another word on any of this, and you are of a technical bent, your homework is to read it!

If you aren’t technical, turn to your favourite geek and do them a favour – tell them to read it and explain what its all about.

The documents are published on the NICCs website:
