NAME

LinkTester -- Click element;

SYNOPSIS

LinkTester(SRC, DST [, KEYWORDS])

Ports: no inputs, 1 output
Processing: push
Drivers: userlevel
Package: grid (core)

DESCRIPTION

Send experimental packets over wireless link to test link characteristics. Packets are sent with source and destination ethernet address SRC_ETH and DST_ETH. The ethernet type code is set to 0x7eee. Keyword arguments are:

START_TIME
Integer. When to start the experiment, in seconds since the ``epoch'' (time_t). Defaults to 5 seconds after router initialization.
ITERATIONS
Unsigned integer. Number of iterations to the run the experiment. In each iteration, each node sends broadcasts, then unicasts, then broadcasts. Defaults to 1.
SEND_FIRST
Boolean. Should this element send its packets at the beginning of the iteration? Otherwise, packets are sent at the end. Defaults to true.
PAD_TIME
Unsigned integer. Milliseconds between experiment phases. Defaults to 10,000 (10 seconds).
UNICAST_SEND_TIME

BROADCAST_SEND_TIME
Unsigned integer. Milliseconds for which to send unicast or broadcast packets during each iteration. Defaults to 10,000 (10 seconds).
UNICAST_PACKET_SZ

BROADCAST_PACKET_SZ
Unsigned integer. Size of unicast or broadcast packets, including ethernet header and experiment header.
UNICAST_LAMBDA

BROADCAST_LAMBDA
Double. Lambda parameter for unicast or broadcast exponentially distributed inter-packet spacing, in milliseconds. Defaults to 1.
