tcp tuning window receiver sizes
i have bit of a tough question..
i'm trying to tune a tcp connection (i'm trying to develop a new tcp protocol) and i'm sending data from one computer to another. When i change the receiver window using
# increase TCP max buffer size
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
# increase Linux autotuning TCP buffer limits
# min, default, and max number of bytes to use
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
it doesn't change the advertised window that the receiver is sending back to the sender. Does anybody know what is going on? No matter what value i set the receiver buffer to, the receiver continues to advertise 63712. Any help is appreciated! thank you!
