Various elements making up the Internet service provider infrastructure, are used to deliver the Internet service which is shared amongst a number of users and the resources are not fully reserved to a particular user. To give an example on how the Internet works, one can compare it to the road network system. Much like the roads are used by a number of people, so is the Internet service. Similar to the road network, when the number of users increase, congestion may occur, possibly resulting in a temporarily slow Internet connection. In order to minimise Internet traffic congestion, service providers may implement traffic management policies to ensure that all network resources are fully used in an efficient manner to maximise the Internet experience of users and minimise congestion.
