VoIP Network Management Use Case Scenarios |

Scenario 1: Validate the Impact of a VoIP Rollout
A network engineer for a government agency is deploying VoIP throughout the network and wants to monitor the success of the rollout by viewing performance of the Cisco® CallManager.
1) The engineer first looks at response time and the number of refused sessions for the CallManager. Both metrics indicate performance problems.
2) The engineer then views the protocol distribution for the network interfaces and notices a large drop in voice traffic from 9:00 AM to 2:30 PM.
3) The Top Conversations view shows the CallManager backing up data to a backup server.
4) An automatic investigation is run at the time the degradation in performance occurs, capturing the cause of the problem.
Resolution
A backup process is causing VoIP traffic on the CallManager to be dropped. The backup process is removed from the CallManager, and VoIP traffic performance levels return to normal.
The NetQoS Performance Center
With the NetQoS Performance Center, you can make more informed decisions based on precise usage data from your network infrastructure. You can improve staff efficiency and collaboration by using a single tool to resolve performance issues rapidly. And you can mitigate risks and validate the impact of planned changes such as MPLS migrations, VoIP deployments, QoS policy implementations, and application rollouts.
The NetQoS Performance Center product suite provides global visibility, via a single web-based management console, into the key metrics necessary to quantify network performance across an organization: end-to-end performance of TCP/IP applications (NetQoS SuperAgent®), traffic analysis (NetQoS ReporterAnalyzer™), device performance (NetQoS NetVoyant®), and VoIP quality of experience (NetQoS VoIP Monitor). The NetQoS Performance Center provides a top-down view of all applications—data, video, and voice—for the entire network infrastructure.
The NetQoS Performance Center scales to the largest networks and provides the real-time and historical data you need to improve the performance of applications delivered over wide area networks.
