technology and computing computer networkingWhat is the size in bytes of the MSS?
Hereof, what is MSS value?
From Wikipedia, the free encyclopedia. The maximumsegment size (MSS) is a parameter of the options field ofthe TCP header that specifies the largest amount of data, specifiedin bytes, that a computer or communications device can receive in asingle TCP segment.
In this way, what is MSS and MTU?
MTU is maximum IP packet size of a given link.MSS is Maximum TCP segment size. MTU is used forfragmentation i.e packet larger than MTU is fragmented.Butin case of MSS, packet larger than MSS isdiscarded.
1 Answer. It is NOT considered a negotiation, itis a statement of an known maximum, and there is not back andforth. It can be different bidirectionally. So one TCP flow canhave a different MSS each way.
