I/O Graph window lets you customize the plots. Since the plot is based on the real data (packets), it is most accurate method of measuring bandwidth. In the figure above, we can clearly see how much bandwidth it consumed during the file transfer. 1 byte is equal 8 bits.ĪLSO READ: Discovering Network Loops (Layer 2) with Wireshark Since the file size and bandwidth rate are in different units, you need to calculate your file size in bits. Let's assume that you have a file size of 1.8GB (gigabytes) to transfer it to your Dropbox and you would like calculate how much time it will take for transferring the file. when you buy a service of 30Mbps (megabits per second) from your ISP (Internet Service Provider), it means you will be able to transfer 30 million bits in a second. We will find the answer in this article, using many functionality in Wireshark.īandwidth is the maximum rate of transferring data from one point to another point in a specific amount of time. Each time there were discrepancies and he was asking for a solution.

Tools like Cacti, Net Limiter, Resource Monitor and Task Manager were used during the test. According to his post on the site, he tried many methods but was not happy with the different results, since he expected similar outcomes for bandwidth usage. A user was asking how to measure his real bandwidth. I came across a question about bandwidth measurement on.
