Subject: [Codel] Worst case conditions - large RTT
Date: Wed, 09 May 2012 13:36:04 -0700 [thread overview]
Message-ID: <4FAAD534.2030100@superduper.net> (raw)
Codel assesses the minimum delay over a fixed time period (the interval)
- what happens when the interval is much smaller that the RTT. For
example a tcp stream is experiencing a 2 second RTT (perhaps due to
bufferbloat at some point), yet the interval is 100ms. The TCP
implementation is a poor one that will ACK a window at a time. Here
codel will drop excessively, and cause low throughput?
Simon
