Inter-Network Mapping

·        http://research.lumeta.com/ches/map/gallery/isp-ss.gif

  This is a nifty color diagram of the Internet showing major ISPs, referenced from http://research.lumeta.com/ches/map/gallery/index.html which has a variety of network maps illustrating the growth of the internet.

 

Internet Weather Report 

These sites are examples of websites that measure “weather” (aka “traffic”) based on frequent “pings” to routers of major internet providers (“ISP’s”).  “Bad weather” is a detected outage of a router, indicated by 100% packet loss.

Bandwidth Speed Tests

·        http://www.toast.net/performance/    

The “toast” site is extremely simple to use and measures connection speed between the user’s computer and any one of a number of commercial servers located throughout the internet.  User can select the target to test against, and the type of data to be used (e.g., image or text).  Result is quickly achieved, and display of result includes a link to “fastest ISP’s”. 

 

      This makes an excellent follow-up activity!

A more complicated test process that reports speed of user’s connection measured against a target site.
