Java Socket TCP Maximum Segment Size -

Is there a possibility to read the TCP "MSS" option header of a SYN packet or it is buried deeply Layers of layers of layers?

Thank you

I'm pretty sure that the latter case is you platform-independent The layer is shielded against the functioning of the TCP stack, otherwise the Java portable will be reduced.

If you insist, you have the option to do socket I / O through JNI.
