SNetMon (Smart Network Traffic Monitoring) is used to monitor both wired and wireless Internet/Intranet network packet from a network segment. This product is able to notify the administrator via alarm, SMS, and Email at the time of peak traffic usage. Its smartness focuses on mainly, optimized algorithm design (according to time-space tradeoff) on low-end platform (CPU: 500MHz and RAM: 512MB only), portability, power consumption, lower cost, and robustness. Network engineers, managers, and computer operators can get benefit to use this product. Small offices, houses, and industrial LAN(wire/wireless) also be monitored using this product. SNetMon is the integration of TS-7800 SBC, TS-GSM1, LCD and Keypad. Unique algorithmic design makes this product significant. The whole system is a combination of devices and the integration of external devices follows a designed method (algorithm). SNetMon is an improvement (based on enhancement of processing power, user friendly and power consumption) of an existing technology.
