Subject: [Bloat] Background Bufferbloat Detector
Date: Wed, 16 Feb 2011 12:46:27 -0500 [thread overview]
Message-ID: <20110216174627.GA20215@brevard.conman.org> (raw)
I've been thinking about this background bufferbloat detector, and I am
wondering why you are bothering with NTP? I understand about the
timestamps, but wouldn't it be easier if you had a program that sent packets
at a known fixed rate? I wrote a simple program that sends a UDP packet
every 20ms; the receiver (same program, different options) records when it
received the packet (which should be 20ms since the last packet received).
It then records the actual delta to a file (which can later be graphed).
Running it I do see variations in the timings; I'm wondering if what I did
is actually relevent to detecting bufferbloat?
-spc (Also, just to mention: it can be used on an IPv6 network, and can
handle multicast addresses for sending and receiving)
