Summary

This Recommendation lays down a framework for supporting and defining the role of network management in IP-based telecommunications networks. IP-based networks generally make use of various telecommunications technologies that support a range of multimedia services such as voice, data, still image and video. Such IP-based networks are referred to here as converged networks. Network Management (NM) goals, principles and functions that are intended for use with IP-based equipment are defined. The major part of this Recommendation suggests ways to monitor traffic and provides some indication of parameters for promptly detecting abnormal network traffic conditions. After detection of an abnormal condition, automatic and possibly manual controls must be temporarily applied to the network to alleviate the problem until it is resolved. It is also necessary to frequently check the performance of the network after applying the NM controls to note whether the control is mitigating the problem and to determine when to modify or remove it from the network.
