About the legends:

Data sources

Name in legend	Meaning
zeros	Use data from /dev/zero
inc	Use the byte sequence 0,1,..255 over and again. It amounts to one add per byte
lcprng	Use data from a very simple, relatively fast (compared to /dev/random or prngd or whatever) linear congruential pseudo random number generator. It amounts to one multiply and two divides per byte

Compression algorithms

Name in legend	Meaning
none	Don't compress at all
gzip	compress using the gzip program via a pipe
bzip2	compress using the bzip2 program via a pipe

Transfer protocol

Name in legend	Meaning
iperf	Use iperf via TCP
iperfudp	Use iperf via UDP
ssh	Use ssh
pnetcat	Use pnetcat via TCP
pnetcatudp	Use pnetcat via UDP

The program can handle different (kinds of) blocksize series.

The program can step either linearly (add a constant each time), or geometrically (multiply by 2 each time).
The program can step through a range of blocksizes you specify (you give the first, the last, and the step (the step only for linear))
The program can use a series of "fundamental constants", generated by sniffing some optiputer traffic, and subtracting off the ethernet, IP and TCP headers, to see if some of these sizes will be faster, due to less packet fragmentation and/or (re)assembly. Yes, these numbers likely won't be relevant to UDP, and possibly even to other networks.

Using the program:

Single test usage:
1. Just select the right options. You can get usage with net-perf-framework -h.
2. For example:
  - net-perf-framework -B -H seki.nac.uci.edu -U strombrg -P fixed 12345 -S $[1024*512] -s zeros -c none -t iperf -m $[60*60]
  - This says to:
    - -B: build/install the prerequisite programs
    - -H seki.nac.uci.edu: test by data transfer to seki
    - -U strombrg: Use username strombrg on the remote host
    - -P fixed 12345: Use only port 12345 on the remote host
    - -S $[1024*512]: Transfer 512 megabytes of data
