SR2ETTStat Element Documentation

NAME

SR2ETTStat -- Click element; Track broadcast loss rates at different bitrates.

SYNOPSIS

SR2ETTStat([KEYWORDS])

Ports: 1 input, at most 1 output
Processing: push
Package: roofnet

DESCRIPTION

Expects probe packets as input. Records the last WINDOW unique (not neccessarily sequential) sequence numbers of link probes from each host, and calculates loss rates over the last TAU milliseconds for each host. If the output is connected, sends probe packets every PERIOD milliseconds. The source Ethernet address ETH must be specified if the second output is connected. This element is a disaster and needs to be rewritten. Keyword arguments are:

ETH
Ethernet address of this node; required if output is connected.
PERIOD
Unsigned integer. Millisecond period between sending link probes if second output is connected. Defaults to 1000 (1 second).
WINDOW
Unsigned integer. Number of most recent sequence numbers to remember for each host. Defaults to 100.
TAU
Unsigned integer. Millisecond period over which to calculate loss rate for each host. Defaults to 10,000 (10 seconds). =back
