 from each other, so that a high-intensity flow does not crowd out low-intensity flows.
 A simple way to put requests into queues is to hash some
 characteristics of the request, modulo the number of queues, to get
-the index of the queue to use.  The hash function uses as input
-characteristics of the request that align with flows.  For example, in

 the Internet this is often the 5-tuple of source and destination
 address, protocol, and source and destination port.
 
 That simple hash-based scheme has the property that any high-intensity flow
 will crowd out all the low-intensity flows that hash to the same queue.
 Providing good insulation for a large number of flows requires a large

 the metaphor of dealing a hand from a deck of cards; each queue is a
