Network Management: Accounting and Performance Strategies

The definitive guide to collecting usage information from Cisco networks

Benoit Claise, CCIE® No. 2868

Ralf Wolter

Understanding network performance and effectiveness is now crucial to business success. To ensure user satisfaction, both service providers and enterprise IT teams must provide service-level agreements (SLA) to the users of their networks–and then consistently deliver on those commitments. Now, two of the Cisco® leading network performance and accounting experts bring together all the knowledge network professionals need to do so.

Network Management: Accounting and Performance Strategies imparts a deep understanding of Cisco IOS® embedded management for monitoring and optimizing performance, together with proven best strategies for both accounting and performance management.

Benoit Claise and Ralf Wolter begin by introducing the role of accounting and performance management in today’s large-scale data and voice networks. They present widely accepted performance standards and definitions, along with today’s best practice methodologies for data collection.

Next, they turn to Cisco devices and the Cisco IOS Software, illuminating embedded management and device instrumentation features that enable you to thoroughly characterize performance, plan network enhancements, and anticipate potential problems and prevent them. Network standards, technologies, and Cisco solutions covered in depth include Simple Network Management Protocol (SNMP) and Management Information Bases (MIB), Remote Monitoring (RMON), IP accounting, NetFlow, BGP policy accounting, AAA Accounting, Network Based Application Recognition (NBAR), and IP SLA (formerly known as SAA). For each, the authors present practical examples and hands-on techniques.

The book concludes with chapter-length scenarios that walk you through accounting and performance management for five different applications: data network monitoring, capacity planning, billing, security, and voice network performance.

Network Management: Accounting and Performance Strategies will be indispensable to every professional concerned with network performance, effectiveness, or profitability, especially NMS/OSS architects, network and service designers, network administrators, and anyone responsible for network accounting or billing.
