Scenario 2: Mitigate the Risks of a VoIP Rollout
A network engineer for a large global manufacturer has recently deployed VoIP to five test sites and wants to understand how successful this test rollout has been.
1) Using the NetQoS Performance Center and Cisco IP SLA data, an engineer identifies jitter and latency problems at the Raleigh, NC test site.
2) The jitter graph shows a large increase in both positive and negative jitter between 10:00 AM and 4:00 PM.
3) A stacked protocol view of the circuit between New York and Raleigh shows a large increase in Windows Media traffic, also occurring between 10:00 AM and 4:00 PM.
4) The top conversations between New York and Raleigh involve various hosts communicating with the Web proxy server.
Resolution
In this case, VoIP quality is suffering because the Raleigh interface is flooded with streaming video data unrelated to business activities.
The engineer enables a rate-limiting policy for streaming video and gives the pilot VoIP rollout Platinum QoS. VoIP quality returns 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.
