I'm going to suggest that these are queues and associated physical
buffers that do two things:
1. hold packets that arrive at a bottleneck for a long as it takes to
send them out a slower link that they came in on, and
2. hold bursts of packets that arrive adjacent to each other until they
can be sent out in a normal spacing, with some small amount of time
between them
That's one thing:
hold packets that have already arrived until they can depart
If you're talking about rate changes, then the queue might absorb a
burst of packets then emit them, i.e., you need a queue that can handle
several packets.
If you're taking about scheduling, then a queue might need as little as
one packet to adjust the outgoing time based on the incoming time.
However, they're both queues, and they both absorb "bursts" (in the
latter case, it's a 'burst' of 1 that needs to wait until a scheduled
slot is available).
