Wolrdwide Comparisons

Before we start to compare Palestine (or more specifically the Middle East)  to the rest of the world it is useful to look at a World Map of Internet Users.  This shows that for most the developed world (US and Canada, W. Europe, Japan, Taiwan, S. Korea) typically 40% or more of the people have Internet connectivity. For the Middle East Palestine it is about 4.9% while Israel is just under factor of 10 greater (45%).  Other nearby countries include Cyprus at 31%, Egypt at 7%, Iraq at 0.1%, Jordan at 11.4%, Lebanon at 13.3%, Saudi Arabia at 10.8%, Syria at 4.2% and Turkey at 17.3%.

From SLAC: 1. Packet Loss, 2. Min RTT to World Regions, 3. Unreachability, 4. Jitter

The left hand figure shows the packet loss to various regions of the world as seen from N. America. Since losses are fairly distance independent no attempt has been made to normalize the data. It is seen that the world divides up into two major super-regions: N. America, Europe, E. Asia and Oceania with losses below 0.1%, and Latin America, C. Asia, Russia, S.E. Asia, S. Asia and Africa with losses > 0.1% and as high as as a few per-cent. All countries are improving exponentially, but Africa is falling further behind most regions.

The left middle figure shows the drop in the Minimum RTT from 2002-2006. The large step for S. Asia in 2003 was due to the change over from satellite to fibre.  as the result of gradual shift from Satellite to fiber. Central Asia (also Afghanistan) has hardly moved in its minimum RTT since it continues to use geostationary satellites.

The right middle graph shows the unreachability of world regions seen from the US. A host is deemed unreachable if all pings of  a set fail to respond. It shows the fragility of the links and is mainly distance independent (the reasons for fragility are usually in the last mile, the end site or host). Again the developed regions  US and Canada, E. Asia, and Oceania have the lowest unreachability (< 0.3%) while the other regions have unreachability from 0.7% to 2%, and again Africa is not improving, with S. Asia having the second worst unreachability.

The right hand graph shows the jitter or variability of world regions seen from the US. The jitter is defined as the Inter Quartile Range (IQR) of the Inter Packet Delay Variability (IPDV i = RTT i - RTT i-1) . The Jitter is relatively distance independent, it measures congestion, and has little impact on the Web and email. It decides the length of VoIP codec buffers and impacts streaming. We see the usual division into dveloped verus developing regions.
