What it is?

NeTAMS stands for Network Traffic Accounting and Monitoring Software. It is built for UNIX and works for networks with Cisco routers or PC Unix routers (Linux/FreeBSD/Solaris). Several methods of traffic gathering are supported (tee/divert/ip_queue/libpcap/ulog/netflow v5 and v9/netgraph), database storage (BerkleyDB/MySQL/PostgresSQL/Oracle/Radius), aggregation, visualization, notification etc. It is possible to block traffic based on quotas, web authorization, account balance (billing); manage bandwidth, MAC assignmant violations, RADIUS services, create a flexible accounting and filtering policies (complete list).

How it works?

NeTAMS is multithreaded daemon application written in C++ which works on your PC-router or dedicated server. IP traffic are either forwarded by this computer, or router receives it from some external box (SPAN port), or another device sending a netflow stream to it. An appropriate database is running there (or at close server). Web server is offering an interface to traffic information to your network cutomers, and gives you a set of Perl/CGI-scripts or Java servlets to manage NeTAMS.

How much does it cost?

NeTAMS is FREE (GPL v3 license) software. All support questions should be solved via forum.
