How to measure the data rate form .sca, .vci and .vec files?

[Lance729]

I am a beginner for omnetpp and INET 🙃 . I saw a use case to measure the data rate supplied in Measuring Data Rate.

I can run this example, but I do not know to use the result files.

Is there an example to teach me how to use the generated result files step by step, for analysing the data rate?

🧠 For example, in the General-#0.vec file, some items have time and value, which are transmission time and transmitted bytes( instead of bits I think). but the data rate is 9824Bytes×8/0.000159174901s*1e-6 = 493.81Mbps. However, the correct answer is about 49Mbps.

❓ Is there an example to teach me how to use the generated result files step by step, for analysing the data rate?
❓ I want to know where am I wrong?

Here is one item in General-#0.vec:

"vectors" : [
           {
               "module" : "DataRateMeasurementShowcase.source.ethernet.macHeaderInserter",
               "name" : "incomingPacketLengths:vector",
               "attributes" : {
                   "interpolationmode" : "none",
                   "recordingmode" : "vector",
                   "source" : "packetLength(merge(packetPushedIn, packetPulledIn))",
                   "title" : "incoming packet lengths",
                   "unit" : "b"
               },
               "time" : [0, 0.000159174901, 0.000338886979,...]
               "value" : [9824, 9824, 9824,...]
