 nGenius Network Performance Management Solution for QoS  
NetScout’s nGenius Performance Management System addresses the many formidable challenges faced by IT network managers implementing QoS policies and delivery classes today. With a single unified system, you can:

  • Optimize delivery of converged and latency-intolerant applications within the appropriate QoS class.
  • Troubleshoot application degradations in real time.
  • Manage and control the cost of WAN services with visibility into QoS classes and the applications within them.

 Factors Driving QoS Use Today 
Today’s large enterprises and government agencies are increasingly turning to QoS traffic classification, specific Differentiated Services Code Pointes (DSCP) in order to:

  • leverage existing network bandwidth more fully,
  • protect mission-critical applications, and
  • ensure the quality of delay-sensitive traffic such as Voice-over-IP and streaming media.

NetScout’s nGenius Performance Manager leverages the rich, actionable information collected by nGenius Probes to provide high definition visibility and the control necessary to monitor, troubleshoot, and plan bandwidth changes for enterprises with QoS implementations.

 QoS Network Performance Management Challenges 
Planning a QoS implementation is difficult, but many are finding it even more daunting to determine whether or not their deployment was successful. Without a means to directly quantify the network traffic utilizing each QoS class, network operators are left to guess whether their prioritization schemes are achieving the desired balance, are unduly impacting or restricting lower priority traffic, or are being compromised by improperly configured network devices.

 Optimizing QoS Deployments with the NetScout Solution  
NetScout's QoS monitoring features allow IT managers to plan, implement, validate and optimize DSCP-based QoS deployments in the context of their entire network and application infrastructures. With a more comprehensive understanding of the impact and effectiveness of QoS traffic management on the total network environment, enterprises can better ensure that their networked applications and services are meeting business priorities.

Network managers use the NetScout Solution to optimize performance of applications in QoS deployments by:

  • Baselining the network to determine the traffic characteristics in order to intelligently assign QoS categories.
  • Establishing response times for priority applications prior to deployment so they can be compared to post-deployment metrics.
  • Analyzing network segments, virtual circuits and associated QoS categories simultaneously by monitoring and trending patterns of application behavior within each DSCP.
  • Evaluating and optimizing the QoS results by monitoring the new traffic patterns and testing the response times of the targeted applications to see whether the QoS goals have been reached.

nGenius Performance Manager provides real-time views of applications in QoS categories as identified by DSCP in physical and virtual circuits running in network segments. This report shows the applications associated with each QoS category. Applications that have been assigned a wrong DSCP will be quickly identified in this view and will make pinpointing the mis-configured device much easier.
