PF_RING

ntop and Silicom Inc join the forces
Since a few months ntop and Silicom have started to work together on various network-related topics. The idea is to enhance PF_RING and  TNAPI in order to offer better products and support for both the community and Silicom customers. Furthermore, Silicom produces very advanced products such as the content director card and the packet processor card, that could solve various network-related tasks including: packet mirroring, tapping, duplication packet steering QoS enforcement packet traffic analysis As these activities are performed in hardware, they operate at wire-speed (at both 1 and 10 …

nProbe complies with the IPFIX specification
Last week I have participated to an IPFIX interoperability event held in Prague, right before the IETF 80. In the picture below you can see me between Benoit Claise (Cisco, one of the IPFIX/NetFlow fathers) and Jiri Novotni (Invea-Tech). nProbe 6.3.x has been successfully tested against all the available implementations including Vermont, SiLK, nfdump/IPFIX (Cesnet). nProbe has passed all the IPFIX interoperability tests as both probe (over SCTP, UDP, and TCP) and collector (UDP), dissecting both IPv4 and IPv6 traffic, and also converting NetFlow-Lite flows into IPFIX flows. Most of you …

Remote nsec TimeStamps using PF_RING and cPacket Devices
PF_RING supports nsec timestamps from some modern NICs, such as those based on the Intel 82580 (e.g. Silicom PE2G4i80). But NIC timestamps require installing and running the application on the machine where the adapter is installed. Furthermore, by the time the traffic gets from the wire to the the NIC, its temporal behavior might have been altered by queuing, buffering, and switching caused by SPAN ports or aggregation devices. cPacket offers products that deliver nanosecond accurate timestamps directly from the wire, before switching, queuing, or bufffering. cPacket inline hardware probes …

nProbe IPFIX Interoperability Tests
Over the past month quite a lot of effort has been put on the IPFIX side of nProbe. Recently, nProbe has been successfully verified by Juniper as an IPFIX (in addition to v9) collector for flows generated by Juniper MX routers, and Cisco Catalyst 4948E switches. In order to further guarantee users that nProbe respects the IPFIX standards, nProbe will be tested against other IPFIX implementations at the IPFIX Interoperability Event that will take place next week in Prague. In the following months, ntop will also try to push in the …
