OVERVIEW
--------
Packet loss occurs when correctly transmitted packets from a source never arrive at the
intended destination. Packets are usually lost due to congestion, e.g., at the
queue of some router, routing problems, or poor network conditions that may
result to datagram damages.
Packet loss application is a novel real-time, end-to-end packet loss estimation method
based on distributed passive network monitoring. This application does not add any overhead
to the network since it passively monitors the network traffic without injecting any probe packets.
At the same time, it estimates almost in real-time the actual packet loss faced by
the active applications. Moreover, it offers the capability for measuring the
loss rates of particular Grid services, allowing for fine-grained per-application
packet loss estimation, which is important in case different applications on the
same path face different degrees of packet loss.
(for more details see : http://dcs.ics.forth.gr/Activities/papers/loss-estimation.coregrid.2006.pdf)
PREREQUISITES
-------------
+ MAPI should have been configured with the flags
--enable-dimapi , --enable-extraflib and --enable-trackflib (need for appmon application),
enabled for the required functions to be included.
+ Packet loss requires a web server and rrdtool version 1.2 or higher (need for appmon application)
(in Debian, apt-get install apache rrdtool)
+ Packet loss requires librrd, libncurses and libcgi (need for appmon application)
(in Debian, apt-get install librrd2-dev libcgicg1-dev)
COMPILATION
-----------
+ Compile packet loss using 'make' (executable files packetloss and appmon will be generated)
Server Configuration
--------------------
- You should configure your webserver to allow cgi script execution.
For Apache, just edit /etc/apache/httpd.conf (or /usr/local/apache/conf/httpd.conf)
and, uncomment the following:
AddHandler cgi-script .cgi
- Also you should define the cgi-bin directory where the server can find the
cgi executables. Simply add:
ScriptAlias /packetloss/cgi-bin/ /var/www/packetloss/cgi-bin/
into the virtual host entry of your apache configuration file.
Web Directory Initialization
----------------------------
- Run the script setupdirs.sh to set up the necessary files in your web
server's root directory. It takes as parameter the absolute path of the
web server's root directory. The script will create a directory packetloss
and all the necessary files and symbolic links for the web interface.
For example :
If you are using the root folder and the root folder is /var/www, then $WEB_DIR=/var/www.
If you are using the user home directories which may are /home/username/public_html then
$WEB_DIR=/home/username/public_html
./setupdirs.sh $WEB_DIR
will create '$WEB_DIR/packetloss', and the web interface will be accessible
at http://www.yourserver.com/packetloss/
Specifically, for the above paths, setupdirs.sh will create:
$WEB_DIR/packetloss/cgi-bin
$WEB_DIR/packetloss/img/lobster-logo.jpg
$WEB_DIR/packetloss/index.html
$WEB_DIR/packetloss/packetloss_top.html -> /home/username/mapi/trunk/applications/packetloss/packetloss_top.html

$WEB_DIR/packetloss/cgi-bin/appmon.cgi -> /home/username/mapi/trunk/applications/packetloss/appmon.cgi
$WEB_DIR/packetloss/cgi-bin/appmon3.cgi -> /home/username/mapi/trunk/applications/packetloss/appmon3.cgi
$WEB_DIR/packetloss/cgi-bin/appmon24.cgi -> /home/username/mapi/trunk/applications/packetloss/appmon24.cgi
$WEB_DIR/packetloss/cgi-bin/appmonWeek.cgi -> /home/username/mapi/trunk/applications/packetloss/appmonWeek.cgi
$WEB_DIR/packetloss/cgi-bin/appmonMonth.cgi -> /home/username/mapi/trunk/applications/packetloss/appmonMonth.cgi
$WEB_DIR/packetloss/cgi-bin/appmonYear.cgi -> /home/username/mapi/trunk/applications/packetloss/appmonYear.cgi
(We assume that mapi has been installed in /home/username/mapi/ directory)
USAGE
-----
- mapid and mapicommd should be running at the two monitoring sensors (see 'trunk/doc/mapitutor.pdf' for details)
- packet loss takes three arguments: the IP address of each monitoring sensor concatenated with it's interface (e.g eth0) and a pcap filter.
Let's see the following scenario:
We want to measure the packet loss between monitoring sensors with IP addresses 139.91.70.38 and 139.91.70.173
Their monitoring interface is eth0.
packetloss should be invoked as: ./packetloss 139.91.70.38:eth0 139.91.70.173:eth0 "host 139.91.70.38 and host 139.91.70.173"
- In order to provide tha figure of appmon application, we must execute this application between the two monitoring sensors.
appmon should be invoked as: ./appmon -V -s 139.91.70.38:eth0 -u 139.91.70.173 "139.91.70.38"
appmon executable file exists in directory /home/username/mapi/trunk/applications/packetloss/
- If packetloss runs on workstation.ics.forth.gr, then the web interface will be accessible at http://workstation.ics.forth.gr/packetloss/
