ITG engineering guidelines
In order to offer voice and fax services over the intranet, keep the network
within a "Good" or "Excellent" QoS level at the Mean+s operating region.
Fax services should not be offered on routes that have only "Fair" or "Poor"
QoS levels.
If the expected QoS levels of some or all routes fall short of "Good", evaluate
the options and costs for upgrading the intranet. Estimate the amount of
one-way delay that must be reduced to raise the QoS level. The section
"Fine-tune network QoS" on
one-way delay. Often this involves a link upgrade, a topology change, or
implementation of QoS in the network.
A decision can be made to keep costs down and accept a temporary "Fair"
QoS level for a selected route. In that case, having made a calculated trade-off
in quality, carefully monitor the QoS level, reset expectations with the end
users and be receptive to user feedback.
