From 76f4afb40fa076ed23fe0ab42c7a768ddb71123f Mon Sep 17 00:00:00 2001 From: Alberto Garcia Date: Mon, 8 Jun 2015 18:17:44 +0200 Subject: throttle: Add throttle group support The throttle group support use a cooperative round robin scheduling algorithm. The principles of the algorithm are simple: - Each BDS of the group is used as a token in a circular way. - The active BDS computes if a wait must be done and arms the right timer. - If a wait must be done the token timer will be armed so the token will become the next active BDS.
