Hi all,

I'm being making some captures in our LTE network on the client side. I couldnt understand what it is representing the goodput graph in the Statistics-Tcp Stream Graphs - Throughput. I believed goodput always be the same or less than throughput but I see for example a throughput around 24 Mbps (this is the rate we got with the bandwitdh test tool we have) and the average throughput is around 12Mbps... What is the goodput graph representing here?. Sorry I cannot add attachments because I'm new here ;) Thanks!

Interesting question (vote up), thank you for that. Never realized that we have that Checkbox in that Graph. In normal cases Goodput and Throughput graph should be more or less the same. Throuput graph displays the amount of transmitted bytes per second and the Goodput Graphs shows the amount of acknowledged Bytes per second. So if you have a lot of packet loss the Goodput will be less than the Throughput.On the other hand a large delay can also cause the Goodput graph is shifted to righthand compared to the throughput graph.
