tcp window concept

[Varun Sharma <vsdssd@xxxxxxxxx>]

Hi,

I am sending 5000 bytes of data in send system call.

struct tcp_sock has max_window and snd_wnd two variable.Which are increase as packet sent out . whereas tcp header window variable value is fix for all packets.can anyone tell what is relationship b/w these windows ? and why max_window and snd_wnd size increase after packets  sent out ?
