Intuition for Theorem 5
v The algorithm replenishes the queue which is going to be in
the most urgent need of replenishment
Ř If we use a lookahead buffer to know the requests “in advance”,
we can identify the queue which will empty earliest
Ř This increases the pipeline latency from when a request is made
until the byte is available.
Example:
1. 160Gb/s line card, b=2560, Q=128: SRAM = 160kBytes,
latency is 8ms.
