9 NETWORK ENGINEERING
NETWORK ENGINEERING is the process concerned
with engineering and optimizing the most
cost-effective design for routing calls within a
network based on load forecasts and other rules
to be employed
10 NETWORK MANAGEMENT
- OBJECTIVE OF NETWORK MANAGEMENT
- To maximize the utilization of available
facilities in order to meet customer services
demands - When necessary, to inhibit traffic that is
causing abnormal conditions (faults).
