Sending TCP packet size more than 536 bytes?

[ZK Chong]

Hi,

May I know it is possible to send TCP packet with payload more than
536 bytes?

Initially, I tried to use Config::SetDefault
("ns3::WifiRemoteStationManager::FragmentationThreshold", StringValue
("8000")) to increase the payload size as I was using Wifi. It does
change the packet size to some extend, but not more than 536.

I tried to change the
Config::SetDefault("ns3::BulkSendApplication::SendSize",
UintegerValue(8224)) as well. But it seems like it doesn't give any
effect to the payload size?

Can anyone give me any hint?

Big thanks in advance.

I think the packet size is set in TcpSocket or Socket class, there is a value attached there for the segment size. Changing the size from application object cannot affect the real segmenting in transport layer, this is what I guess.

Best,
