renetcol home page

renetcol ( RENATER  NetFlow Collector) is a NetFlow collector under GPL. NetFlow is a technology originally proposed by  Cisco, that is currently under standardization in  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

• Class of services traffic distribution for an IPv4 prefix: here

Next features

• IPv6 accounting for Prefix
• IPv6 accounting for AS Number
• New architecture of core: SMP arch, to reached the million of analysed flows per second on only one hardware.
• DDoS detection
• nfcapd format export

White Paper

soon, few documents on how use renetcol in WAN, LAN and security context...
