WebMSS stands for maximum segment size. MSS is used by TCP at layer 4 of the Internet, the transport layer, instead of layer 3. MSS is only concerned with the size of the payload within each packet. It is calculated by subtracting the length of TCP and IP headers from MTU. While packets that exceed a router's MTU are either fragmented or dropped ...
