renetcol ([http://www.renater.fr RENATER] [http://www.cisco.com/en/US/products/ps6601/products_ios_protocol_group_home.html NetFlow] Collector) is a NetFlow collector under GPL. NetFlow is a technology originally proposed by [http://www.cisco.com Cisco], that is currently under standardization in [http://www.ietf.org/html.charters/ipfix-charter.html IPFIX] IETF working group. renetcol works with '''!NetFlow Data Export version 9''', which allows to monitor IPv6, Multicast and MPLS flows, in addition to the IPv4 ones.

The main functionnalities of renetcol are:
 * Real-time NetFlow viewer (if you've ever dreamed of using tcpdump on an IP operator backbone, you should test renetcol)
 * RRD accounting for IPv4 subnet (CIDR)
 * RRD accounting for BGP AS number
 * RRD accounting for IPv6 links (new in release 0.0.14)
 * Inter-POP flows Matrix
 * DoS attack detection

=== Next features ===

 * Flow historic
 * Accounting for IPv6 subnet
 * New architecture of core: SMP arch, to reached the million of analysed flows per second on only one hardware (in November 2011).
 * DDoS detection
 * nfcapd format export
