Currently netmap and PF_RING are supported, but they are difficult to deploy and are driver independent. This research project investigate the possibility of compiling an enhanced kernel module from kernel headers, eliminating the need to download full kernel source code. Also, this module should be as fast as other techniques without reliance on network driver modifications.

The goal is to produce a kernel module that can be compiled without any significant overhead or knowledge of how to build kernel modules.
