Evaluate an Application's Efficiency

Instructions to evaluate how much of the bandwidth for one application or type of traffic is due to retransmissions

Steps:

1. Create a traffic class if one does not already exist for the traffic you want to analyze.
   
   For more information, see Traffic Tree Overview and/or Traffic Classification Overview.
   

2. Select your traffic class and graph its Network Efficiency graph.
   
   
   
   PacketWise's Network Efficiency graph shows the percentage of bandwidth wasted by retransmissions. PacketWise knows the rates of throughput and retransmissions for any traffic class, and calculates percentages of wasted bandwidth. With the Network Efficiency graph, you can track the current retransmission rate or explore its history.
   
   When you create a Network Efficiency graph on one traffic class, PacketWise reports the percentage of retransmissions for only the traffic belonging to the class.
   
   Consult examples of applications' efficiency graphs and their interpretations to see how to interpret efficiency graphs.
   
   
3. If you want to monitor efficiency and retransmissions automatically without needing to check them manually, the adaptive response feature can be helpful. See Analyze Efficiency with Traffic Performance Agents.
   

Well-managed bandwidth prevents network inefficiency. PacketWise's control features, including TCP rate control, help avoid router queues, time-outs, and dropped packets so that you have less retransmissions.
