Understanding TCP/IP Maximum Segment Size (MSS) When Throughput Matters #mss #throughput

#tcp/ip #tcp #mtu
In this video, we will uncover why the TCP MSS (Maximum Segment Size) is not always the default setting derived from the MTU (Maximum Transmission Unit). We will review the 3-way handshake using Wireshark and use diagrams in Packet Tracer to describe when the MSS needs to be adjusted. We will then explain why we need to adjust the MSS when throughput matters.
