A main purpose of this experiment is to study the internet traffic pattern of three internet operators in Thailand over the ADSL Internet during August 24, 2010 to 20 September, 2010. There are three 4M/512Kbps ADSL’s (TOT, 3BB, and TRUE) connecting to the same site located at Pathumthani
province in Thailand as shown in a figure 1. Ping packets with 100 bytes were sent continuously from three Ubuntu Linux computers to the same domestic web server (203.151.206.73) via three Internet operators as ref. [10]. Experimental results are shown in figures 3-8 and tables 1-3.
