Round Robin Load Balancing Algorithm
Round Robin scheduling services queues on a rotating basis and is activated only when an
interface has more traffic than it can handle. A queue is given an amount of bandwidth
irrespective of the incoming traffic on that interface. This queue then moves to the back of the
list. The next queue is given an equal amount of bandwidth, and then moves to the end of the
list; and so on, depending on the number of queues being used. This works in a looping
fashion until a queue is empty.
