TrafMeter is efficient Windows-based software that enables accurate measurement of Internet traffic for accounting and sharing purposes. It allows users to set flexible measurement conditions, such as based on IP address or protocol, ensuring precision in tracking data usage.

TrafMeter further offers an authorization agent to authenticate users from LAN using TrafMeter Native Authentication or Windows Domain Authentication. It also allows users to construct filters and rules based on usernames to resolve issues with traffic accounting in networks with dynamic allocated IP addresses and IP/MAC address spoofing by users. Overall, TrafMeter is a comprehensive and effective solution for network traffic management and internet sharing.
