Jul 24, 2019 How to determine the optimal MTU and MSS size - Tips and The maximum segment size (MSS) is a parameter of the options field of the TCP header that specifies the largest amount of data, specified in bytes, that a computer or communications device can receive in a single TCP segment. It does not count the TCP header or … Maximum Segment Size (MSS) - Palo Alto Networks For example, if you configure an MSS adjustment size of 42, you expect the MSS to equal 1458 (the default MTU size minus the adjustment size [1500 - 42]). However, the TCP packet has 4 extra bytes of IP options in the header, so the MSS adjustment size (20+20+4) equals 44, which is larger than the configured MSS adjustment size of 42.

TCP Maximum Segment Size tuning - IBM

The TCP protocol includes a mechanism for both ends of a connection to advertise the MSS to be used over the connection when the connection is created. Each end uses the OPTIONS field in the TCP header to advertise a proposed MSS. The MSS that is chosen is … Network Performance Analysis: TCP MSS | Network Computing If the MSS value is less than the maximum, it may be due to a smaller IP MTU setting. For example, if the IP MTU is 200 bytes smaller to support VPN traffic, the TCP MSS will also be 200 bytes less. The diagram below illustrates the size dependency between the IPv4 MTU and the TCP MSS. TCP MSS, MTU and PMTU Discovery - Cisco Community
