Controlable per-Flow Load Balancing (CFLB) is an initiative to revisit current load-balancing techniques. These techniques suffer from the fact that they use hash-based functions to balance packet. This prevent hosts to control the path taken by their packets.

CFLB consists of an invertible mechanism that allows sources to easily steer packets over any load-balanced path. CFLB consists in multiple implementation parts:

* A Linux kernel implementation of the CFLB-router forwarding path.
