Post-installation network measurements
The network design process is continuous, even after implementation of the IP telephony and
commissioning of voice services over the network. Network changes in regard to real IP telephony
traffic, general intranet traffic patterns, network controls, network topology, user needs and
networking technology can make a design invalid or non-compliant with QoS objectives. Review
designs against prevailing and trended network conditions and traffic patterns every two to three
weeks at the start, and after that, four times a year. Ensure that you keep accurate records of
settings and any network changes on an ongoing basis.
Ensure that you have valid processes to monitor, analyze, and perform design changes to the IP
telephony and the corporate intranet. These processes ensure that both networks continue to
conform to internal quality of service standards and that QoS objectives are always met.
