Summary: ‘Net Neutrality’ has gathered increasing momentum as a market issue, with AT&T, Verizon, major European telcos and Google and others all making their points in advance of the Ofcom, EC, and FCC consultation processes. This is Telco 2.0’s input, analysis and recommendations. (September 2010, Foundation 2.0,, Executive Briefing Service, Future of the Networks Stream).

In this paper, Telco 2.0 recommends that the appropriate general response to concerns over ‘Net Neutrality’ is to make it easier for customers to understand what they should expect, and what they actually get, from their broadband service, rather than impose strict technical rules or regulation about how ISPs should manage their networks.
In this article we describe in detail why, and provide recommendations for how.

Analysis of Net Neutrality Issues
‘Net Neutrality’ = Self-Interest (Poorly Disguised)
‘Net Neutrality’ is an issue manufactured and amplified by lobbyists on the behalf of competing commercial interests. Much of the debate on the issue has become somewhat distracting and artificial as the ‘noise’ of self-interested opinion has become much louder than the ‘signal’ of potential resolutions.
The libertarian ideal that the title implies is a clever piece of PR manipulation of ideas of freedom of access of information, and freedom from interference. For the most part, this is far from the reality of the motives of the players engaged in the debate.
Additionally, the ‘public’ net neutrality debate is being driven by tech-savvy early adopters whose views and ‘use cases’ are not statistically representative of the overall internet population.
This collection of factors has created a strange landscape of idealist and specialised viewpoints congregating around the industry lobbyists’ various positions.
However, behind the scenes, the big commercial players are becoming increasingly tense, and we have recently experienced a marked reluctance from senior telco executives to comment on the issue in public.
Our position is that, beyond the hyperbole, the fair and proper management of contention between Internet Applications and ‘Specialised Services’ is important in the interests of consumers and the potential creation of new business models.
What, exactly, is the ‘problem’ and for whom?
Rapidly increasing use of the Internet and Specialised Services, particularly bandwidth hungry applications like online video, is causing (or, at least, will in theory cause) increasing contention in parts of the network.
The currently expressed primary concerns of net neutrality activists are that some consumers will receive a service whose delivery has been covertly manipulated by an external party, in this case their ISP. Similarly, some application and service providers fear that their services are or will consequently be discriminated against by telcos.
Some telcos think that certain other large and bandwidth-hungry applications are receiving a ‘free ride’ on their networks, and their corporate owners consequently receiving the benefits of expensive network investments without contribution. As a consequence, ISPs argue that they should be entitled to unilaterally constrain certain types of applications unless application providers pay for the additional bandwidth.
It’s a Commercial Issue, not a Moral Issue
One of the areas of obfuscation in the ‘Net Neutrality’ debate is the confusion between two sets of issues in the debate: ‘moral and legal’ and ‘commercial’.
Moral & legal issues include matters such as ‘freedom of expression’ and the right to unfettered internet access, the treatment of pirated content, and censorship of extreme religious or pornographic materials. We regard these as subjects for the law where the service is consumed / produced etc., but that have in some places become entangled in the ‘Net Neutrality’ debate and which should not be its focus.
The commercial issue is whether operators should be regulated in how they prioritise traffic from one commercial application over another without the user’s knowledge.
What causes this problem?
Contention can arise at different points between the service or application and the user, for example:
- Caused by bulk traffic from users and applications in the ‘core network’ beyond the local exchange, (akin to the general slowing of Internet applications in the evening in Europe due to greater local and U.S. usage at that time);
- Between applications on a bandwidth restricted local access route (e.g. ADSL over a copper pair, mobile broadband).
As a service may originate from and be delivered to anywhere globally, the first kind of contention can only be truly be managed if there is either a) an Internet-wide standard for prioritising different types of traffic, or b) a specific overlay network for that service which bypasses the internet to a certain ‘outer’ point in the network closer to the consumer such as a local exchange. This latter class of service delivery may be accompanied by a connection between the exchange and the end-user that is not over the internet – and this is the case in most IPTV services.
To alleviate issues of contention, various ‘Traffic Management’ strategies are available to operators, as shown in the following diagram, with increasingly controversial types of intervention to the right.
Figure 1 – Ofcom’s Traffic Management Continuum
Is It Really a Problem?
Operators already do apply traffic management techniques, an example of which was given by 3UK’s Director of Network Strategy at the recent Broadband Stakeholder Group (BSG) event in London, who explained that at peak times in the busiest cells, 3 limits SS7 signalling and P2P traffic. He explained that they selected these categories because they are essentially ‘background’ applications that have little impact on the consumer’s experience, and it was important to keep down latency so that more interactive applications like Web browsing functioned well. A major ‘use case’ for 3UK was identifying which cells needed investment.
In 3UK’s case, there was perhaps surprisingly more signalling traffic than there was P2P. Though this is a mobile peculiarity, it illustrates that assumptions about problems in managing traffic management can often be wrong, and it is important that decisions should be taken on the basis of data rather than prejudice.
While there are vociferous campaigners and powerful commercial interests at stake, it is fair to say that the streets are not often full of angry consumers waving banners reading ‘Hands off my YouTube’ and knocking on the doors of telcos’ HQs. While a quick and entirely non-representative survey of Telco 2.0’s non-technical relatives-of-choice revealed complete ignorance and lack of further interest in the subject, this does not necessarily mean that there is not, or could not be, a problem, and it is possible that consumers could unwittingly suffer. On balance though, Telco 2.0 has not yet seen significant evidence of a market failure. We also believe that the mechanisms of the market are the best means of managing potential conflict.
A case of ‘Terminological Inexactitude’
We broadly agree with Alex Blowers of OFCOM, who said that ‘80% of the net neutrality debate is in the definition’ at the recent BSG conference.
First, the term ‘Net Neutrality’ does not actually distinguish which services it refers to – does ‘Net’ mean ‘The Internet’, ‘The Network’, or something else? To most it is taken to mean ‘The Internet’, so what is ‘The Internet’? Despite the initial sense that the answer to this question seems completely obvious, a short conversation within or outside the industry will reveal an enormous range of definitions. The IT Director will give you a different answer from your non-technical relatives and friends.
These ambiguities have the straightforward consequence that the term ‘Net Neutrality’ can be used to mean whatever the user wants, and its use is therefore generally a guarantee for mindless circular arguments and confusion . In other words: perfect conditions for lobbyists with partial views.
For most people, ‘the internet’ is “everything I can get or do when my computer or phone is connected online”. A consumer with such a view probably has a broadband line and an internet service and is among those, in theory at least, most in need of protection from unscrupulous policy management that might favour one form of online traffic over another without their knowledge or control. It is their understanding and expectation of what they have bought against the reality of what they get that we see as the key in this matter.
In this paper, we discuss two classes of services that can be delivered via a broadband access line.
1. Access to ‘The Internet’ (note capitalisation), which means being able to see and interact with the full range of websites, applications and services that are legitimate and publicly available. We set out some guiding principles below on a tighter definition of what services described as ‘The Internet’ should deliver.
2. ‘Specialised Services’ are other services that use a broadband line, that often connect to a device other than a PC (e.g. IPTV via set-top boxes, smart meters, RIM’s Blackberry Exchange Server (BES)) or a service that may be connected to a PC but via a VPN, such as corporate video conferencing, Cloud or Enterprise VOIP solutions.
While ‘Specialised Services’ are not by our definition pure Internet services, they can also have an effect in certain circumstances on the provision of ‘The Internet’ to an end-user where they share parts of the connection that are in contention. Additionally, there can be contention between services on ‘The Internet’ from multiple users or applications connected via a common router.
Additionally, fixed and mobile communications present different contexts for the services, with different potential mechanisms for control and management. Mobile services have the particular difference that, other than signalling, there is no connection between device and the network when data services are not being used.
The Internet: ‘Appellation Controlee’?
One possible mechanism to improve consumer understanding and standards of marketing services is to introduce a framework for defining more tightly services sold as “Internet Access”.
In our view, services sold as ‘The Internet’ should:
- Provide access to all legitimate online services using the ‘public’ internet;
- Perform within certain bounds of service performance as marketed (e.g. speed, latency);
- Be subject to the minimum necessary ‘traffic management’ by the ISP, which should only be permissible in specific instances, such as contention (e.g. peak hour use) ;
- Aim to maintain consistent delivery of all services in line with reasonable customer expectation and best possible customer experience (as exemplified in a ‘code of best practice’);
- Provide published and accessible performance measures against ‘best practice’ standards.
Where a customer has paid extra for a Specialised Service, e.g. IPTV, it is reasonable to give that service priority to pre-agreed limits while in use.
The point of defining such an experience would be to give consumers a reference point, or perhaps a ‘Kitemark’, to assure them of the nature of the service they are buying. In instances where the service sold is less than that defined, the service would need to be identified, e.g. a ‘Limited Internet Access Service’.
The Internet isn’t really ‘Neutral’
To understand the limitations and possible advantages of ‘traffic management’, and put this into context, it is worth briefly reviewing some of the other ways in which customer and service experiences vary.
Different Services Work in Different Ways
Many Internet Services use already use complex mechanisms to optimise their delivery to the end-user. For example:
- Google has built a huge Content Delivery Network, using fibre to speed communications between data centres, dedicated delivery of traffic to international peering points, and equipment at ISPs for expediting caching and content delivery, to ensure that its content is delivered more rapidly to the outer edges of the network;
- BBC News Player uses an Akamai Content Delivery Network (CDN) similarly;
- Skype delivers its traffic more effectively by optimising its route through the peer-to-peer network.
Equally, most ISPs are able to ‘tune’ their data services to better match the characteristics of their own network. Although these assets are only available to the services that pay for, own, or create them, none of these techniques actively slows any other service. Indeed, and in theory, by creating or using new non-congested routes, they free capacity for other services so the whole network benefits.
Consumer Experiences are Different too
Today’s consumer experience of ISP services varies widely on local factors. Two neighbours (who happen to be on different nodes) could, in theory get a very different user experience from the same ISP depending on factors such as:
- Local congestion (service node contention, loading, router and backhaul capacity);
- Quality and length of local loop (including customer internal wiring);
- Physical signal interference at the MDF (potentially a big issue where there is lots of ULL);
- Time of day;
- Router make and settings (particularly relating to QOS, security).
These factors will, in many cases, massively outweigh performance variation experienced from possible ‘traffic management’ by ISPs.
Internet Protocols try to be ‘Fair’
The Internet runs using a set of data traffic rules or protocols which determine how different pieces of data reach their destinations. These protocols, e.g. TCP/IP, OSPF, BGP, are designed to ensure that traffic from different sources is transmitted with equal priority and efficiency.
Further Technical Fixes Are Possible
Network congestion is not an issue that appeared overnight with the FCC’s 2005 Comcast decision. In fact, the Internet engineering community has been grappling with it with some success since the near-disaster in the late 1980s that led to the introduction of congestion control mechanisms in TCP.
Much more recently, the popular BitTorrent file sharing protocol, frequently criticised for getting around TCP’s congestion control, has been adapted to provide application-level congestion control. The P4P protocol, created at MIT and tested by Verizon and Telefonica, provides means for P2P systems and service provider networks to cooperate better. However, it remains essentially unused.
A further consideration is that it is necessary to be realistic about what can be expected – we have heard the benefits from traffic-shaping cited as an extension of around 10% in the upgrade cycle in the best-case scenario.
It’s Complex, not Neutral
It is therefore simply not the case that all Internet services progress from point of origin somewhere in the cloud of cyberspace to the end-users via a random and polite system. There are assets that are not equally shared, significant local variations, and there are complex rules and standards.
‘The Internet’ is a highly complex structure with many competing mechanisms of delivery, and this is one of its great strengths – the multiplicity of routes and mechanisms creates a resilient and continually evolving and improving system. But it is not ‘neutral’, although many of its core functions (such as congestion control) are explicitly designed to be fair.
Don’t Block the Pipes, Lubricate the Market
In principle, Telco 2.0 endorses developments that support new business models, but also believes that the rights of end-users should be appropriately protected. They have, after all, already paid for the service, and having done so should have the right to access the services they believe they have paid for within the bounds of legality.
In terms of how to achieve this balance, it’s very difficult to measure and police service levels, and we believe that simply mandating traffic management solutions alone is impractical.
Moreover, we think that creating a fair and efficient market is a better mechanism than any form of regulation on the methods that operators use to prioritise services.
Empower the Customer
There are three basic ways of creating and fulfilling expectations fairly, and empowering end-customers to make better decisions on which service they choose.
- Improving Transparency – being clear and honest about what the customer can expect from their service in terms of performance, and making sure that any traffic management approaches are clearly communicated.
- Enabling DIY Service Management – some customers, particularly corporate clients and advanced users, are able and can be expected to manage significant components of their Internet services. For example, mechanisms already exist to flag classes of traffic as priority, and many types of CPE are capable of doing so. It’s necessary, however, that the service provider’s routers honour the attribute in question and that users are aware of it. Many customers would need support to manage this effectively, and this could be a role for 3rd parties in the market, though it is unlikely that this alone will result in fairness for all users.
- Establishing Protection – for many customers, DIY Service Management is neither interesting nor possible, and we argue that a degree of protection is desirable by defining fair rules or ‘best practice’ for traffic management.
Not all customers are alike
‘Net Neutrality’ or any form of management of contention is not an issue for corporate customers, most of whom have the ability to configure their IP services at their will. For example, a financial services trader is likely to prioritise Bloomberg and trading services above all other services. This is not a new concept, as telcos have been offering managed data services (priority etc) to enterprise customers for years over their data connections and private IP infrastructure.
Some more advanced consumer users can also prioritise their own services. Some can alter the traffic management rules in their routers as described above. However, these customers are certainly in the minority of Innovators and Early Adopters. Innovation in user-experience design could change this to a degree, especially if customers have a reason to engage rather than being asked to do their service provider’s bottom line a favour.
The issue of unmanaged contention is therefore likely to affect the mass market, but is only likely to arise in certain circumstances. To illustrate this we have selected a number of specific scenarios or use cases in which we will show how we believe the principles we advocate should be applied. But first, what are our principles?
Lubricate the Market
There are broadly three regulatory market approaches.
- ‘Do nothing’ – the argument for this is that there is no evidence of market failure, and that regulating the service is therefore unnecessary and moreover difficult to do. We have some sympathy for this position, but believe that in practice some of direction is needed as recommended below.
- ‘Regulate the Market’ – so that telcos can do what they like with the traffic but customers can choose between suppliers on the basis of clear information about their practices and performance. A pure version of this approach would involve the specification of better consumer information at point of sale and published APIs on congestion.
- ‘Regulate the Method’ – with hard rules on traffic management rather than how the services are sold and presented. The ‘hard’ approach is potentially best suited to where the ‘market’ is insufficiently competitive / open. This method is difficult to police as services blur and ‘the game’ then becomes to be categorised as one type of service but act as another.
Telco 2.0 advocates a hybrid approach that promotes market transparency and liquidity to empower customers in their choices of ISP and services, including:
- Guidelines for operators on ‘best practice in traffic management’, which in general would recommend that operators should follow the principle of “minimum intervention”;
- Published assessments on how each operator meets these guidelines that make understanding operator’s performance on these issues straightforward for customers.
The criteria of the assessment would include the actual performance of the operator against claimed performance (e.g. speed, latency), and whether they adhere to the ‘Code of Best Practice’.
How might it work?
The communication of this assessment could be as simple as a ‘traffic light’ style indicator, where a full Internet service meeting best practice and consistently achieving say 90% of claimed performance would be ‘Green’, while services meeting lower standards / adherence or failing to report adequately would be signalled ‘Amber’ or ‘Red’. The principles used by the operator should also be published, though utilising this step on its own would run the risk of the “Licence Agreement” problem for software – which is that no-one reads them.
We’ll be working on refining our guidelines and thoughts on how an indicator or other system might work by working through some specific ‘Use Cases’ outlined below. In the meantime, we recommend the suggestions made by long-time Telco 2.0 Associate Dean Bubley in his Disruptive Analysis’s ‘Draft Code of Conduct for Policy Management and Net Neutrality’.
It is our view that as long as Telcos are forced to be open, regulator (and consumer bodies) can question or, ultimately, regulate for/against behaviours that could be beneficial/damaging.
The Role of the Regulator
We believe that the roles of the regulator(s) should be to:
- Develop an agreed code of best practice with industry collaboration;
- Agree, collect and publish measures of performance against the code;
- Make it as easy as possible to switch providers by reducing the ‘hassle factor’ of clumsy processes, and by releasing consumers from onerous contractual obligations in instances of non-compliance with the code or performance at a ‘Red’ standard;
- Monitor, publicise, and police market performance in line with appropriate regulatory compliance procedures.
We draw a parallel with what the UK regulator, Ofcom, used to do for telephony:
- Force all providers with over a certain market share to report key performance metrics;
- Publish these (ideally on the web, real time and by postcode);
- Make it as easy to switch providers as possible;
- Continuously review the set of performance metrics collected and published.
New ‘Enhanced Service’ Business Models?
Additionally, we see the following possible theoretical service layers within an Internet Service that could be used to create new business models:
- ‘Best efforts’ – e.g. ‘We try our best to deliver all of your broadband services to maximum speed and performance, but some services may take priority at certain times of the day in order to cope with network demands. The services will not cease to work but you may experience temporarily degraded performance.’
- ‘Protected’ – akin to the ambulance lane (e.g. Health, SmartGrid – packets that are always delivered/could be low or higher bandwidth e.g. a video health app but the principle of priority stands for both).
- ‘Enhanced Service’ – e.g. a TV service that the customer has paid for (e.g. IPTV) or that a network will (or might) pay extra to deliver assure a higher degree of quality.
One possibility that we will be exploring is whether it could be possible to create an ‘On-demand Enhanced Service’. For example, to deliver a better video streaming experience the video provider can pays for their traffic to take priority over other services with the express consent of the customer. This may be achieved by adding a message to the Enhanced Service e.g. ‘Click here to use our Enhanced Video Service where we’ll pay to get your video to you quicker. This may cause degradation to the service to other applications currently active on your broadband line while you are using the Enhanced Video Service’.
We have long thought that there is scope for innovation in service design and pricing – for example, rather than offering a (supposed) continuous 8Mbps throughput (which most UK operators can’t actually support and have no intention of supporting), why not offer a lower average rate and the option to “burst” up to high speed when required? ISPs actually sell each other bandwidth on similar terms, so there is no reason why this should be impossible.
Example Scenarios / Use Cases
We’ve identified a number of specific scenarios which we will be researching and developing ‘Use Cases’ to illustrate how these principles would apply. Each of these cases is intended to illustrate different aspects of how a service should be sold to, and managed by / for the customer to ensure that expectations are set and met and that consumers are protected appropriately.
Fixed ‘Use Cases’
- Contention between Internet services over an ADSL line on a copper pair, e.g. Dad is editing a website, Daughter is watching YouTube videos, with a SmartGrid meter in operation over a shared wireless router. This is interesting because of the limited bandwidth on the ADSL line, plus consideration of the SmartGrid monitoring as a ‘Specialised Service’, and potentially also as a ‘Protected Service’ in our exploratory classification of potential service classes.
- Contention between Internet and Specialised Services over an ADSL line on a copper pair, e.g. Dad is streaming an HD video on the internet, daughter is watching IPTV. This is interesting because of the limited bandwidth on the ADSL line and the additional factor of the IPTV service over the broadband connection. Unlike a DOCSIS 3 cable link, where the CATV service is additional to the Internet service and in fact can be used to offload applications like iPlayer, the DSL environment means that “specialised services” will contend with public Internet service.
- Managed Vs Unmanaged Femtocells over an ADSL connection. An Unmanaged Femtocell is e.g. a Sprint Femtocell over an AT&T ADSL connection, where the Femtocell is treated purely as another source of IP traffic. A Managed Femtocell is e.g. a Softbank Femtocell operating on a Softbank ADSL line, using techniques such as improved synchronisation with the network to produce a better service. An examination of alternate approaches to managing Femtocell traffic is interesting: 1) because a Femtocell inherently involves a combination of mobile and fixed traffic over different networks, so draws out fixed/mobile issues, and; 2) it is useful to work through how a Managed Femtocell Use Case might work within the market approach we’ve defined.
- A comparison of a home worker using videoconferencing with remote colleagues in two scenarios: one using VPN software and configured router; the second using Skype with no local configuration. The objective here is to explore the relative difference in the quality of user experience as an illustration of what is possible in a advanced user ‘DIY’ management scenario.
- The ‘Use Case’ of an ‘On-demand Enhanced Service’ for a professional web video-cast, with the consumer experience as outlined above. The idea here is that the user grants temporary permission to the video provider and the network to temporarily provide an ‘Enhanced Service’. This role of this ‘Use Case’ is to explore how and whether a ‘sender pays’ model could be implemented both technically and commercially in a way that respected consumer concerns.
- HDTV to the living room TV. This is interesting because the huge bandwidth requirements needed to deliver HDTV are far beyond those originally envisaged and have a potentially significant impact on network costs. Would user expectations of such a service permit e.g. buffering to deliver it without extra cost, or might this also enable a legitimate ‘two-sided’ sender pays model where the upstream customer (e.g. the media provider) pays?
Mobile ‘Use Case’
- VOIP over mobile. Is it right that VOIP over mobile networks should be treated differently from how it is over fixed networks?
Telco 2.0’s Position Vs the Rest
There is reasonably common ground between most analysts and commentators on the need for more transparency in Internet Access service definition and performance and management standards, though there is little clarity yet in the ways in which this clarity might be achieved.
The area which is most contentious is the notion of ‘non-discrimination’ – that is of allowing ISPs to prioritise one form or source of traffic over another. AT&T are firmly in favour of ‘paid prioritisation’ whereas Google/Verizon are not, and says ‘wireline broadband providers would not be able to discriminate against or prioritize lawful Internet content, applications or services in a way that causes harm to users or competition’.
Interestingly, in the Norwegian Government’s Net Neutrality Guidelines issued in 2009, provision is made that allows operators to manage traffic in certain circumstances in order to protect the network and other services.
Free Press are a US activist movement who champion ‘Net Neutrality’. While we have accord with their desire for freedom of speech, and understand the imperative to create a more level-playing field for media in the US, our position is not aligned in terms of enshrining total neutrality globally by regulation.
In terms of the regulators’ positions, the UK’s Ofcom is tentatively against ‘ex-ante’ regulation, whereas the FCC seems to favour non-discrimination as a principle. The FCC is also asking whether mobile and fixed are different – we say they are, although as the example of 3UK shows, the differences may not be the ones you expect. Ofcom is also already looking at how it might make switching easier for customers.
We also note that US-based commentators generally see less competition on fixed internet services than in Europe, and less mobile broadband options for customers. Our position is that local competitive conditions are a relevant consideration in these matters, albeit that the starting point should be to regulate the market as described before considering a stronger stance on intervention in circumstances of low local competition.
Conclusion & Recommendations
‘Net Neutrality’ is largely a clever but distracting lobbyists’ ploy that has gathered enormous momentum on the hype circuit. The debate does create a possible opportunity to market and measure broadband services better, and that’s no bad thing for customers. There may also be opportunities to create new business models, but there’s still work to be done to assess if these are material.
‘Lubricate the Market’
1. “Internet Access” should be more tightly defined to mean a service that:
- Provides access to all legitimate online services using the ‘public’ internet;
- Performs within certain bounds of service performance as marketed (e.g. speed, latency);
- Is subject to the minimum necessary ‘traffic management’ by the ISP, which should only be permissible in specific instances, such as contention (e.g. peak hour use);
- Maintains consistent delivery of all services in line with reasonable customer expectation and best possible customer experience (as exemplified in a ‘code of best practice’);
- Provides published and accessible performance measures against ‘best practice’ standards.
2. Where a customer has paid extra for a ‘Specialised Service’, e.g. IPTV, it is reasonable to give that service priority to agreed limits while in use. Services not meeting these criteria should be named, e.g. “Limited Internet Access”.
3. ISPs should be:
- Able to do ‘what they need’ in terms of traffic management to deliver an effective service but that they must be open and transparent about it;
- Realistic about the likely limits to possible benefits from traffic-shaping.
4. The roles of the regulator are to:
- Develop an agreed code of best practice with industry collaboration;
- Agree, collect and publish measures of performance against the code;
- Ensure sufficient competition and ease of switching in the market;
- Monitor, publicise, and police market performance in line with appropriate regulatory compliance procedures.
We have also outlined:
- Principles for a code of best practice;
- A simple ‘traffic light’ system that might be used to signal quality and compliance levels;
- ‘Use Cases’ for further analysis to help refine the recommended ‘Code of Practice’ and its implementation, including exploration of an ‘On-Demand Enhanced Service’ that could potentially enable new business models within the framework outlined.
