VoIP Performance Management and Optimization is the definitive guide for every network engineer, architect, and operations professional who must manage and optimize VoIP networks. The authors bring together state-of-the-art techniques for proactively monitoring and troubleshooting voice-related problems in large networks and for ensuring that customer service level agreements (SLAs) are consistently met or exceeded. In Part I, the authors review the most common performance-related problems faced by Cisco customers who have deployed VoIP in their networks. They introduce generic network and performance management concepts, as well as the fundamental techniques of SLA management in VoIP networks. In Part II, they introduce today's leading VoIP deployment models, identifying the inherent problems and design challenges posed by each. In Part III, they present a comprehensive approach to diagnosing problems in VoIP networks using key performance indicators (KPI) and proactively addressing those problems before they impact service. They also introduce a tools-based strategy for gauging the health of VoIP networks and improving network performance by analyzing and correlating performance counters, call detail records, Call Agent trace logs, and more. This section includes a full chapter on performing trend analysis and using the results for capacity planning and traffic engineering leading to overall VoIP system optimization.
