The internet traffic pattern of the big Internet
operators (TOT, 3BB, and TRUE) over ADSL in Thailand
for one week is observed at Nonthaburi site [10]. Ping
packet trains are used to measure the congestion of the
network operators via ADSL link in terms of the mean
Round Trip Time (RTT), the packet loss, the mean deviation
(mdev). Additionally, Ref. [10] presented the performance
comparison of three Internet operators. In this paper, the
observing of the internet traffic pattern is extent to one
month and additional Pathumthani site. In addition, the
seasonal internet traffic of three ADSL operators is
