Traffic Shaping

October 29, 2007

Traffic shaping is the process whereby broadband providers and ISPs limit traffic, usually at particularly busy times of day, in order to ensure the efficient use of available bandwidth.

This can be in order to provide an acceptable level of service for all users, or to prioritise some types of traffic over the network (eg business traffic, or VoIP).

Most broadband packages come with a download allowance, and even unlimited download allowances will – in nearly all cases – have a fair use policy which prevents particularly heavy internet users from using so much bandwidth that other people’s internet connections are affected. Traffic shaping may involve the invoking of these policies for very heavy bandwidth users.

Cybersquatting / Typosquatting

September 1, 2007

Cybersquatting involves buying a domain name which is made up of, or contains, another company’s name or brand name, or a miss-spelling of that name.

An increasingly popular tactic is typosquatting – buying a miss-spelled domain name to take advantage of users accidentally typing in an incorrect brand or company name into a URL or search engine – the webpage it sends the user to will often then include adverts for other products.

Many affected companies use ICANN’s Uniform Domain Name Resolution Policy to resolve such disputes. Some adversely affected companies do start legal proceedings, but this can be hampered by the fact that legal comeback varies from country to country.

TCP / IP

July 19, 2007

TCP/IP, or Transmission Control Protocol/Internet Protocol, standardises communication between computers over the internet. TCP/IP can also be used in private networks.

Transmission Control Protocol (TCP) is the standard for two computers establishing a connection with each other over the internet and transmitting streams of data, and also ensuring that data packets are received in the right order.

The Internet Protocol (IP) finds out the address of the data packet and ensures it is routed to the right destination based on that address, even if there is no direct connection to that address.

Every computer with access to the internet uses TCP/IP .

21CN – 21st Century Network

June 29, 2007

21CN, or the 21st Century Network, is BT’s next generation network. An IP (internet protocol) network, it will offer communications from anywhere to any device, and will deliver a range of converged services including voice, data, mobile TV, and video.

At present, the BT network runs on a Public Switched Telephone Network (PSTN) – 21CN will see it move to an Internet Protocol (IP) network. PSTN is expensive to maintain – 21CN will bring together several systems and the new approach should be both more cost-effective, and ensure that next generation converged services are fast and efficient. The programme is expected to cost £10 billion, with savings of £1 billion a year expected.

On the 21CN network your calls from your home or business will still travel along copper wires to your exchange, as they do now – but at the exchange they will move onto the new IP system along with data traffic.

BT has already run a 21CN trial, linking BT exchanges in central London, Woolwich and Cambridge, carrying over 160 million calls. BT is now migrating live customers – 350,000 customers in Cardiff and the surrounding area are expected to be migrated onto the new IP network by the end of 2007.

The Exchange

June 23, 2007

The exchange, or telephone exchange, is a collection of switches housed in one place that connects phone calls. Phone lines from consumers or businesses in the local area (or within the “local loop”) meet here.

If you have broadband delivered via a phone line (rather than cable) the distance between you and the exchange can affect your broadband speed.

On Demand TV and Video

June 11, 2007

Broadband providers are increasingly offering on demand TV and video services via a customer’s broadband connection. These may be free, or pay-for.  Services include:

  • BT Vision from BT – will provide digital TV over broadband to BT Total Broadband users.
  • 4OD, from Channel 4 – video on demand (of Channel 4 programmes) delivered via yourcomputer.
  • The BBC’s iPlayer – when it launches, it should include BBC Television programmes available for download, free for UK licence fee payers, for up to a week after transmission.

On Demand TV is bandwidth-heavy so users will need a robust and fast download connection in order to make the most of it.

Not all IPTV services are on demand – IP TV refers simply to the method of delivery and could include scheduled programmes, while on demand TV is available when the customer wants to view it.

Triple Play

April 18, 2007

Triple Play refers to a bundle made up of three communications services, broadband, TV and phone, delivered over a single broadband connection.

As most internet bundles were initially composed of two services only (broadand and phone), the triple play bundle from cable comanies NTL and Telewest (now Virgin Media) was considered a real step forward. Virgin Media now also offers Quad Play.

Speed Test

April 6, 2007

A broadband speed test is a Java applet that, at the click of a button, can measure your upload and download broadband speeds.

If you use a broadband speed checker you should check your broadband speed at different times of day and on different days of the week so you can see if your speed is being affected by factors such as other users going online at the same time as you.

Internet Protocol TV – IPTV

April 3, 2007

IPTV, or Internet Protocol TV, is the transmission of television via the internet. This could mean simply watching scheduled TV programmes, or viewing television on demand with thousands of TV programmes and films available for an indvidual to watch when they want.

IPTV can be delivered over cable or ADSL (broadband via a BT phone line) – either to a pc, or to a set-top box to be watched on the TV.

Not surprisingly, it requires a high speed broadband connection to ensure quality and consistency.
