At the end of the month, analyze each site's QoS information. Table 36
provides a sample.

Declines in QoS can be observed through the comparison of QoS between the
last period and current period. If a route does not meet the QoS objective, take
immediate action to improve the route's performance.
Simple Network Management Protocol (SNMP)-based Network
Management Systems (NMS) provide a useful way of monitoring a real-time
network from end to end. This is important for networks using VoIP. User
complaints of slow downloads are no longer enough to diagnose problems.
An NMS can ensure that problems on a network running real-time traffic are
solved quickly to maintain high-quality service.
SNMP NMS software can be configured to perform the following actions:
• map the network
• monitor network operation through polling of network devices
• centralized alarm management through SNMP traps
• notify network administrators of problems
