In March and April 2007 we worked with people from Palestine and the University at Buffalo to install PingER Measurement Points (MPs) in Al Quds University (AQU) in Abu Dis on the Wst Bank and the Islamic University of Gaza (IUG) in Gaza City. They were both connected to the Mediterranean fibre optic cable though at first the host used at Al Quds AQU was routed through Barak an Israeli commercial Internet porovider. There is a probability they the Palestinian hosts will lose their connection to the Mediterranean fibre optic cable in Summer 2007.
Al Quds AQU successfully installed PingER without help. It has been measuring and reporting since March 23, 2007. It has been very reliable with few losses of data.
Warren Matthews of Georgia Tech had to step stepped in and assist IUGaza in getting PingER2 running. There were problems with the cronjob and possibly ntpd. IUGaza IUG has been monitoring successfully since April 7th, 2007. They did not monitor data all day on April 22. There have been problems on 2 days gathering the data where I have either contacted the IUGaza site contact (Apr 28th to fix the web server) or had to re-run the gathering script. It was having problems again on May 3-7, 2007 and has been reported to the contact.

Routes
The main Autonomous System Domains System (ASNAS) domains in the routes from SLAC to the Middle East countries for the sites we monitor are shown in the figure to the left below. It can be seen that many providers are used. Al Quds connects to PADI2. The Palestinian sites (Gaza and the West Bank) use different providers from each other and from the neighboring countries. The figure on the right shows the ASNs ASs used to route from Al Quds AQU to various countries of the world.

The fallowing graph shows the daily TCP throughput seen from SLAC to Al Quds University, IUGaza and the Palestine Standards Institution (www.psi.gov.ps). It can be seen that the performance is very variable, probably due to diurnal congestion. In addition IUGaza and the Palestinian Standards Institution have similar derived throughput, whil Al-Quds University is lower.
The monthly average Round Trip Times (RTTs) from Al Quds and IUGaza are shown below. The individual data points daily avergae(average_RTT) are shown to show the variability.
