TCP ’ s Congestion Control Implementation in Linux Kernel

Linux kernel implements different functionalities related to the network stack. One such functionality is TCP’s congestion control. In this paper, we describe parts of the linux kernel code that deals with TCP’s congestion control implementation. Our main focus here is going through different functions that are used during TCP’s congestion control operation. Although there are many similarities between TCP’s implementation in different kernel versions, this description uses the Linux kernel v 3.6.6.
