FastNetMon - A high performance DoS/DDoS load analyzer built on top of multiple packet capture engines (NetFlow, IPFIX, sFlow, AF_PACKET, SnabbSwitch, netmap, PF_RING (obsoleted), PCAP).
We detect hosts in the deployed network sending or receiving large volumes of traffic, packets/bytes/flows, per second and perform a configurable action to handle that event. These configurable actions include notifying you, switching off the server, or blackholing the client.
Flow is one or more ICMP, UDP, or TCP packets which can be identified via their unique src IP, dst IP, src port, dst port, and protocol fields.
At a very high level integration with FastNetMon is fairly simple. In both cases the work flow is the same and the main difference being the port numbers provided. The port numbers are configurable.
Configure the IP of the server running FastNetMon using port 6343. This port number is configurable.
Configure the IP of the server running FastNetMon using port 2055. This port number is configurable.

Travis status:
- Complete BGP Flow Spec support, RFC 5575
- Process and distinguish incoming and/or outgoing traffic
- Trigger block/notify script if an IP exceeds defined thresholds for packets/bytes/flows per second
- Thresholds can be configured per-subnet with the hostgroups feature
- Announce blocked IPs via BGP to routers with ExaBGP
- GoBGP integration for unicast IPv4 announcements (you will need to build support for this manually).
- Full integration with Graphite and InfluxDB
- API (you will need to build support for this manually)
- Redis integration
- MongoDB integration
- Deep Packet Inspection (DPI) for attack traffic
- netmap support (open source; wire speed processing; only Intel hardware NICs or any hypervisor VM type)
- SnabbSwitch support (open source, very flexible, LUA driven, very-very-very fast)
- Filter NetFlow v5 flows or sFLOW packets with LUA scripts (useful for excluding particular ports)
- Supports L2TP decapsulation, VLAN untagging and MPLS processing in mirror mode
