Hey packet people!
There is a big difference between the Maximum Transmission Unit (MTU) on an ethernet connection or IP interface and the Maximum Segment Size in TCP. In this video we will take a look at how and where each is set, how it impacts the encompassed data, and how the network can adjust these settings.
These core concepts will help when troubleshooting broken or slow connections due to MTU or MSS.
Hope it helps in troubleshooting with Wireshark!
