Hi, I am trying to look through the implementation of timers in TCP.I found the functions that implement the three main timers but havent been able to trace the code.if someone could tell me for example how the kernel implements retransmission and what values of the tcp_opt structure it makes use of. Basically i just want to trace the entire code from where the kernel timer ticks to how it compares values from say the retransmission queue and then actually decides what packets to retransmit. thanks a lot. --- - Amit http://amitshah.nav.to/ amitshah@gmx.net -- Kernelnewbies: Help each other learn about the Linux kernel.
