Motivation

We have different set of landmarks deployed all over the world, this map enables us to see them based on their location. There was a need to segregate different types of landmarks and identifying which ones are enabled and disabled. Map can be seen at http://www.slac.stanford.edu/comp/net/wan-mon/viper/tulip_map.html

Types of Landmarks

  1. PlanetLab Landmark sites
  2. PingER Landmark sites
  3. PerfSONAR Landmark sites

Methodology

Two XML files are used for getting node information. These XML files are created from a perl script at /afs/slac.stanford.edu/package/pinger/tulip/generateActiveNodes.pl. The html file (tulip_map.htm) is placed at /afs/slac.stanford.edu/www/comp/net/wan-mon/viper

  • Unknown macro: {html}

    <A href="http://www.slac.stanford.edu/comp/net/wan-mon/viper/active-rss.xml" mce_href="http://www.slac.stanford.edu/comp/net/wan-mon/viper/active-rss.xml">active-rss.xml</A> is used to plot the active nodes for the landmarks above

  • Unknown macro: {html}

    <A href="http://www.slac.stanford.edu/comp/net/wan-mon/viper/disable-rss.xml" mce_href="http://www.slac.stanford.edu/comp/net/wan-mon/viper/disable-rss.xml">disable-rss.xml</A> is used to plot the disabled nodes for the landmarks above

XML Pattern for a node

<item>
<title>"United Kingdom"</title>
<link>87.84.153.115</link>
<lat>54.988</lat>
<lon>-1.6</lon>
<host>csplanet02.cs-ncl.net</host><region>Europe</region>
<type>PlanetLab</type>
<subject>dPl</subject>
</item>

Distinguishing subject tags

<subject>aPl</subject> // Active Planet Lab
<subject>dPl</subject> // Disabled Planet Lab
<subject>aPingER</subject> // Active PingER
<subject>dPingER</subject> // Disabled PingER
<subject>aPerf</subject> // Active PerfSONAR
<subject>dPerf</subject> // Disabled PerfSONAR
