ITU-T E.416

Network Management (NM) for B-ISDN traffic requires real-time monitoring of current network status and network performance. This Recommendation is intended to support and define the role of network management in the B-ISDN and broadband services. It explains the network management principles and functions. The major part of this Recommendation suggests the way traffic must be monitored and provides some indication of parameters for promptly detecting abnormal network traffic conditions. After the detection of the abnormal condition, automatic and possibly manual controls will be temporarily applied to the network to alleviate the problem until the problem is resolved. It is also necessary to frequently check the effects of the NM controls to note whether the control is actually helping with the problem and to determine when to modify or remove it from the network.
