Summary: Find out about the experience you can expect from our broadband products.

Below you can see an overview of the traffic management policies used on our current broadband products.

  • The information is presented in a series of KFI (Key Fact Indicator) tables, showing when speeds are limited, and to what extent
  • Publication of these KFI tables is part of our commitment to a voluntary code of practice aiming to make traffic management easier to understand and compare between service providers
  • For more information on this code of practice, please see the Broadband Stakeholders Group website
  • To find out more about how and why we apply traffic management, please see our Traffic management guide
  • See our Broadband download and Broadband upload guides for a complete breakdown of when and where rate limits apply

To get started, click on the name of the product you want to see more information about.

If you're using our KFI tables to compare our products to other ISPs:

*This excludes any service, content, application or protocol that an ISP is required to block by UK law and child abuse images as informed by the list provided by the Internet Watch Foundation.

** Managed services (Max Premium and Elevate) are available as add-ons. These increase upload speed and priority.

*** Not all traffic is managed during peak hours. Please see our Broadband download and Broadband upload guides for a complete breakdown of when and where rate limits apply.

**** If no entry is shown against a particular traffic type, no traffic management is typically applied to it, though overall network management rules shall apply.

Glossary

Traffic management

Traffic management is the term used to describe a range of technical practices undertaken to manage traffic across networks.

The different outcomes achieved by the use of technical practices can include:

  • the prioritisation of certain types of traffic in busy times or busy areas to ensure that it is of an adequate quality
  • the slowing down of certain traffic types that are not time-critical at busy times or busy places
  • ensuring compliance with a consumer's contract, for example slowing down of traffic for the heaviest users
  • supporting the delivery of managed services, for example to ensure a guaranteed quality of service for a specific piece of content

Managed services

The majority of internet traffic is delivered on a 'best efforts' basis. A managed service, on the other hand is one whereby an ISP offers 'quality of service' that can guarantee a certain level of performance, so that the content, service or application can be delivered without risk of degradation from network congestion. Such a quality of service arrangement can be made between an ISP and a content or service provider or directly between an ISP and the consumer.

Best Efforts

This phrase relates to the delivery of internet traffic where traffic management is applied without distinctions based on the source of that traffic.

Slowed down

This outcome is achieved by the deployment of technologies that can decrease the priority of traffic types deemed to be non-time critical on the network e.g. slowing down traffic such as downloads during busy times and busy periods.

Prioritised

This outcome is achieved by the deployment of technologies that increase the priority given to certain traffic types, e.g. time-critical traffic such as video. This outcome can also be achieved as a consequence of slowing down other selected traffic which reduces the overall data flow on the network.

Heavy users

Heavy users can cause peak traffic volumes to exceed the engineered maximum load. In practice this refers to a very small proportion of users of a network whose use is excessive to the extent that it impacts on other users.
