T 2.32 Inadequate line bandwidth
A mistake frequently made when planning networks is to dimension
bandwidth solely on the basis of the current requirements, disregarding the
fact that the network will be subject to ever-increasing bandwidth
requirements, e.g when new IT systems are integrated into the network or
when the amount of transmitted data increases.
When the bandwidth of the network is no longer sufficient, the transmission
rate in the network is severely restricted for all users. File access in remote IT
systems is slowed down considerably, for example, when the available
network bandwidth has to be shared with other users, initiating a high amount
of network traffic(capacity is subject to a high level of utilisation by other
users), such as applies when large files are transferred from one IT system to
another.
Example:
An organisation with several sites installs a network based on ISDN-S o lines
for data communication. After the installation of a GUI based Intranet, the
data communication nearly broke down. Finally, only a switch to S 2M
communication channels provided the necessary network bandwidth.
