 * IPVS:        Overflow-Connection Scheduling module
 *
 * Authors:     Raducu Deaconu <[email protected]>
 *
 * Scheduler implements "overflow" loadbalancing according to number of active
 * connections , will keep all connections to the node with the highest weight
 * and overflow to the next node if the number of connections exceeds the node's
 * weight.
 * Note that this scheduler might not be suitable for UDP because it only uses
 * active connections
