In today’s business reality, distributed enterprises heavily rely on applications for communication,

collaboration, and effective day-to-day operations. At the same time, IT is challenged with managing

application delivery in an environment that is rapidly changing. The number of business applications is

growing, application architectures are increasingly complex, application traffic is proliferating, and traffic

patterns are difficult to predict. In addition, driven by security, regulatory, and economic considerations,

enterprises are embracing data center consolidation, desktop virtualization, and network and application

convergence to maximize the value of their IT investments. This demands comprehensive application and

network visibility to successfully deliver disparate applications in a complex IT environment.

Cisco

Network Analysis Module (NAM) is a powerful network-aware performance assurance solution that delivers

unparalleled visibility into application and network performance to help ensure the consistent and efficient delivery of

applications and services to end users. It combines performance monitoring, traffic analysis, and advanced

troubleshooting to provide a comprehensive solution that meets the performance management needs of today’s

dynamic, evolving enterprises. The visibility allows IT to effectively use control and optimization mechanisms, such

as quality of service (QoS) and Wide Area Application Services (WAAS), to improve application performance.

The unique design of Cisco NAM combines a rich set of embedded data collection capabilities and performance

analytics with a remotely accessible, web-based management console, all of which reside on a single network

module or new high-performance appliance. The network module can be installed into Cisco Catalyst

6500 Series

Switches, Cisco

7600 Series Routers, Cisco

Integrated Services Routers (ISR) Generation 2 or first generation

Cisco ISRs. The Cisco

NAM 2204 and NAM 2220 appliances extend the reach of the NAM to places in the network

either not currently served by the blades or where higher performance monitoring is essential.

Cisco NAM includes a Traffic Analyzer GUI, which provides quick access to both configuration menus and real-time

and historical performance reports.

Table 1 lists the key features of Cisco NAM.

Cisco NAM Features

Feature

Description

Application performance
monitoring

Offers intelligent application performance monitoring and real-time visibility for voice, video, and data applications.
Cisco NAM helps improve the operational efficiency of IT organizations by allowing them to proactively detect
performance degradation, quickly identify its source, and troubleshoot the underlying issues.

Transaction-aware application
response time monitoring

Analyzes TCP-based application packets as they travel from the client through the network to the data center and
out again, providing insight into network round-trip time, server response time, data transfer time, transaction time,
and so on to monitor application performance.

Voice-over-IP (VoIP) and video
packet quality analysis

Analyzes voice and video packet streams and provides visibility into key network performance indicators to
maximize the quality of the user experience.

Comprehensive flow-based
monitoring

Automatically identifies hundreds of protocols and provides real-time and historical performance reports on hosts,
conversations, and applications using critical network resources.

LAN and WAN monitoring in one
solution

Provides visibility into traffic from local and remote switches and routers for comprehensive traffic monitoring.
