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/netflow v5), database storage (BerkleyDB/MySQL/PostgresSQL), aggregation, visualization, notification etc. It is possible to block traffic based on quotas, authorization ID, empty balance (billing); manage bandwidth, create a flexible accounting and filtration policies.
