Network Learning Series: Understanding Ethernet MTU, IP MTU and MSS

This video covers the concepts around Ethernet MTU , IP MTU and TCP MSS. Ever struggled to understand what a maximum transmission unit or a TCP MSS is? Never really understood why you would change these values? Hopefully this video is here to help! Topics covered include: - Ethernet MTU (Maximum Transmission Unit) - IP MTU (Maximum Tranmission Unit) - Fragmentation - TCP MSS (Maximum Segment Size) - TCP MSS Adjust - MTU Path Discovery with ICMP - How you would change the IP MTU or MSS for tunneling technologies like GRE.
