MaximumTransmissionUnit:
|
|
|
|
|
Largest protocol data unit that the layer can pass onwards
|
|
|
|
|
can be discovered by running tracepath
|
|
|
|
|
|
|
|
|
|
SendingWindowSize , ReceivingWindowSize:
|
|
|
|
|
the size of Tx/Rx window, by packet
|
|
|
|
|
|
|
|
|
|
ForwardErrorCorrectionGroupSize:
|
|
|
|
|
The the size of packet to generate a Forward Error Correction
|
|
|
|
|
packet, this is used to counteract packet loss.
|
|
|
|
|
|
|
|
|
|
AcknowledgeNoDelay:
|
|
|
|
|
Do not wait a certain of time before sending the ACK packet,
|
|
|
|
|
increase bandwich cost and might increase performance
|
|
|
|
|
|
|
|
|
|
Dscp:
|
|
|
|
|
Differentiated services code point,
|
|
|
|
|
be used to reconized to discriminate packet.
|
|
|
|
|
It is recommanded to keep it 0 to avoid being detected.
|
|
|
|
|
|
|
|
|
|
ReadTimeout,WriteTimeout:
|
|
|
|
|
Close the Socket if it have been silent for too long,
|
|
|
|
|
Small value can recycle zombie socket faster but
|
|
|
|
|
can cause v2ray to kill the proxy connection it is relaying,
|
|
|
|
|
Higher value can prevent server from closing zombie socket and
|
|
|
|
|
waste resources.
