When RSS was introduced some years ago, operating systems had the chance to scale also when handling network packets as RSS allowed incoming packets to be distributed across processor cores. Unfortunately RSS…
Packet Capture Performance at 10 Gbit: PF_RING vs TNAPI
Many of you are using PF_RING and TNAPI for accelerating packet capture performance, but have probably not tested the code for a while. In the past month we have tuned PF_RING performance…
Power to see all
Almost a decade ago Dr Ian Graham was in Europe for a series of conferences and I have met him in person along with other people from Politecnico di Torino, that were…

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…
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…
Developing Monitoring Applications based on PF_RING
Many people use PF_RING just as a "better" libpcap. PF_RING is much more than that, as it can significantly simplify the design of network monitoring applications as well better exploit modern multi-core…
