- Measures analyzes & reports round-trip times, losses, availability,
throughput ...
- Uses ubiquitous ping, no special host, or software to install/configure
at remote sites
- Low impact on network << 100bits/s, important for many DD sites
- Covers 75+ countries (99% of Internet connected population)
- Provides quantitative historical (> 8yrs) and near real-time
information
- Aggregate by regions, affiliations etc.
- How bad is performance to various regions, rank countries?
- Trends: who is catching up, falling behind, is progress being made?
- Compare vs. economic, development indicators etc.
- Use for trouble shooting setting expectations, presenting to policy
makers, funding bodies

- Contacts
- New contacts in Vietnam, the Philippines, Serbia/Montenegro, Belarus,
Macedonia, Albania, Turkey, and Tunisia
- Looking for contacts in Cuba, Kenya, Algeria and South Africa, Uganda
- Added hosts in Macedonia, Serbia/Montenegro, Belarus, Turkey, Armenia,
Mexico and Azerbaijan.
- Increased hosts monitored from CERN to give better European view
- Now monitoring 60 countries

- Within region performance better
- E.g. Ca|US-NA, Hu-SE Eu, Eu-Eu, Jp-E Asia, Au-Au, Ru-Ru
- Africa, Caucasus, Central & S. Asia all bad

- 35+ monitoring sites in 15 countries
- Plan to add ICTP Trieste if funded
- Other projects used toolkit, e.g. XIWT
- SLAC with help from FNAL
- Digital Divide collaboration (MOU) with ICTP, Trieste
- eJDS
- They are looking for a EU grant for eJDS and PingER
- Need funding for coming year:
- Working with DoE, NSF, Pew Charitable Foundation …
- Tasks:
- (0.5 FTE) ongoing maintain data collection, explain needs, reopen
connections, open firewall blocks, find replacement hosts, make
limited special analyses, prepare & make presentations, respond to
questions
- (+ 0.5 FTE) extend the code for new environment (more countries, more
data collections), fix known non-critical bugs, improve visualization,
automate reports generated by
hand today, find new country site contacts, add route histories and
visualization, automate alarms, update web site for better navigation,
add more DD monitoring sites/countries, improve code portability
- Also looking for small grants for helpers in developing countries
- ICFA: show importance to policy makers, funding agencies, identify
sympathetic contacts at agencies, get support

- Performance is improving all over
- Performance to developed countries are orders of magnitude better than
to developing countries
- Poorer regions 5-10 years behind
- Poorest regions Africa, Caucasus, Central & S. Asia
- Some regions are:
- catching up (SE Europe, Russia),
- keeping up (Latin America, Mid East, China),
- falling further behind (e.g. India, Africa)
