T 2.11 Insufficient bandwidth planning
A mistake frequently made when planning networks is to dimension
bandwidth solely on the basis of the current requirements. This approach fails
to take account of the fact that
- the need for expanding a network can never be ruled out;
- the bandwidth of the network has to be enlarged due to increasing data
transfer requirements.
- due to new requirements to be met by the given network, other cables have
to be installed;
Expansion of the network will be possible only to the extent permitted by the
installed cables or by the availability of space for additional cables. Especially
in the case of covered wiring (piping, plaster-covered conduit subways, etc.),
even where space is available, it is often impossible to insert additional cables
without damaging new or old cables. The only alternative here is to pull out
the existing cables and to draw in all cables, old and new, at the same time.
The resulting operational hindrance and costs can be considerable.
