TrafficWatcher is a program which measures the traffic (transmitted and received number of bytes) over a RAS connection. Additional features make the program a compact tools for the internet user of today. Originally, the program has been developed to be aware of the cumulated traffic of a specific internet RAS connection which is running under a volume account.


  • Measures the transmitted and received bytes during a single RAS connection and cumulated over a longer period.
  • Displays a history graph which shows the current speed of your connection. The maximum transfer rate can be entered.
  • Dials automatically, if the connection has been interrupted
  • Warns, if the traffic has reached a given limit
  • Interrupts the connection, if the traffic has reached a given limit
  • Updates your dynamic IP address via DynDNS
  • Minimize TrafficWatcher into the system tray


  • TrafficWatcher has been tested on Windows XP. It should run on Windows 2000. Problems have been seen under Windows 98
