Overview
==========
This package contains a UDP echo server and client. Both the client and the
server support RFC 862 (default) and support TR-143 UDPEchoPlus if passed the
`--echoplus` flag.
Software Requirements
=====================
* GNU GCC 4.2.1
* GNU Libtool 2.4
* GNU Autoconf 2.65
* GNU Automake 1.11.1
* Git 1.7.2.3
Utilities
=========
akcom-udpecho
-------------
_akcom-udpecho_ is a shell utility for testing UDP echo servers. _akcom-udpecho_
supports for RFC 862 compliant servers and TR-143 UDPEchoPlus compliant
servers. If the UDP Echo variant is not specified, _akcom-udpecho_ will
attempt to determine the variant by examining the __TestRespSN__,
__TestRespRecvTimeStamp__, and __TestRespReplyTimeStamp__ fields of the
UDPEchoPlus packet for non-zero values.
Example usage (RFC 862 compliant):
$ akcom-udpecho -c 5 --rfc udpecho.example.com 30006
UDPECHO udpecho.example.com:30006 (209.112.131.108:30006): 20 bytes
udpecho_seq=1 time=17.3 ms
udpecho_seq=2 time=13.7 ms
udpecho_seq=3 time=19.0 ms
udpecho_seq=4 time=18.3 ms
udpecho_seq=5 time=12.6 ms
--- udpecho.example.com udpecho statistics ---
5 packets transmitted, 5 packets received, 0.0% packet loss
round-trip min/avg/max = 12.6/16.1/19.0 ms
$
Example usage (TR-143 UDPEchoPlus compliant):
$ akcom-udpecho -c 5 --echoplus udpecho.example.com 30006
UDPECHO udpecho.example.com:30006 (209.112.131.108:30006): 20 bytes
udpecho_seq=1 time=20.9 ms delay=1.5 ms adj_time=19.4 ms
udpecho_seq=2 time=17.4 ms delay=2.8 ms adj_time=14.6 ms
udpecho_seq=3 time=19.7 ms delay=0.3 ms adj_time=19.4 ms
udpecho_seq=4 time=18.7 ms delay=0.7 ms adj_time=18.0 ms
udpecho_seq=5 time=14.1 ms delay=2.7 ms adj_time=11.4 ms
--- udpecho.example.com udpecho statistics ---
5 packets transmitted, 5 packets received, 0.0% packet loss
round-trip min/avg/max = 14.1/18.1/20.9 ms
adjusted round-trip min/avg/max = 11.4/16.5/19.4 ms
$
akcom-udpechod
--------------
_akcom-udpechod_ is simple UDP echo server. The __drop__ and __delay__
features should not be used concurrently by multiple clients. Currently
_akcom-udpechod_ processes each packet sequentially which causes all packets
received before previous packets have been processed to be skewed when using
the __drop__ and __delay__ features.
Example usage (RFC 862 compliant):
akcom-udpechod \
--port 30007 \
--pidfile /var/run/akcom-udpecho/akcom-udpecho.pid \
--user nobody \
--group nobody \
--delay=10000 \
--drop=10 \
--rfc
Example usage (TR-143 UDPEchoPlus compliant):
akcom-udpechod \
--port 30007 \
--pidfile /var/run/akcom-udpecho/akcom-udpecho.pid \
--echoplus \
--user nobody \
--group nobody \
--delay=10000 \
--drop=10 \
--echoplus
