Currently all Internet Service Providers connect
their customers to the Internet with the aid of one of the four
companies (called Tier 1 providers) who own the global infrastructure
that is the backbone of the Internet. ISP's purchase the required
amount of connection to the Internet (called bandwidth) from
the Tier 1 providers based on the number of users each ISP has.
Due to the cost of bandwidth, ISP's calculate
their need based on the number of users that they believe will
connect at any one time, (usually 1 in 100). However it is likely
that 20 to 30 users in every 100 will be online at peak times,
this is known as contention. This means you share your connection
with other users slowing you down to an unbearable speed or
preventing connection to the Internet altogether. At Mr Webspace we will always provide enough bandwidth to allow all of
our users to get online at any one time at the optimum speed
of you equipment.
Diagram to show how contention is similar to
traffic congestion.
