TCP Maximum Segment Size (MSS) and Relationship to IP Datagram Size (Page 3 of 3) Specifying a Non-Default MSS Value. Naturally, there are likely to be cases where the default MSS is non-ideal, so TCP provides a means for a device to specify that the MSS it wants to use is either smaller or larger than the default value of 536. Transmission Control Protocol - Wikipedia The maximum segment size (MSS) is the largest amount of data, specified in bytes, that TCP is willing to receive in a single segment. For best performance, the MSS should be set small enough to avoid IP fragmentation , which can lead to packet loss and excessive retransmissions.

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(7): TCP protocol - Linux man page TCP_MAXSEG The maximum segment size for outgoing TCP packets. In Linux 2.2 and earlier, and in Linux 2.6.28 and later, if this option is set before connection establishment, it also changes the MSS value announced to the other end in the initial packet. Values greater than … TCP MSS Adjustment - Nokia
