Coverage
• In last 9 months added:
– Several sites in Russia (thanks GLORIAD)
– Many hosts in Africa (5=>36 now in 27 out of 54 countries)
– Monitoring sites in Pakistan and Brazil (Sao Paolo and Rio)
• Now monitoring 650 sites in 115 countries
• Working to install monitoring host in Bangalore, India

World View
S.E. Europe, Russia: catching up
Latin Am., Mid East, China: keeping up India, Africa: 7 yrs behind
India, Africa: falling behind

As expected Brazil to L. America
is good
Actually dominated by Brazil to

To Chile & Uruguay poor since

Achieving throughput
• User can’t achieve throughput available (Wizard gap)
• Big step just to know what is achievable

Collaborations/funding
• Good news:
– Active collaboration with NIIT Pakistan to develop network
monitoring including PingER
• Travel funded by US State department for 1 year
– FNAL & SLAC continue support for PingER management
and coordination
• Bad news:
– DoE funding for PingER terminated
– Proposal to EC 6th framework with ICTP, ICT Cambridge UK,
CONAE Argentina, Usikov Inst Ukraine, STAC Vietnam VUB
Belgium rejected
– Proposal to IDRC/Canada February, no word
• Hard to get funding for operational needs
– For quality data need constant vigilance (host disappear,
security blocks pings, need to update remote host lists …)7
New features in works
(with NIIT)
• Improve new site set-up tools
• Improve management
– Discover non working links faster
• Improve access to data and meta data
– Provide data base with lat/long, country etc.
– Add web services access
• Improve visualization:
– Provide map with drill down to node information
– Automate production of long term trend plots for regions
– More node selection capabilities
• Traceroute measurement and analysis
