[Bloat] Background Bufferbloat Detector

[Sean Conner]

  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?

	handle multicast addresses for sending and receiving)
