ZC

Last year Intel announced a new family of 100 Gigabit network adapters, code-name Columbiaville. These new adapters, based on the new Intel Ethernet Controller E810, support 10/25/50/100 Gbps link speeds and provide…

As you know we're working at 100 Gbit for a while, not just in terms of network speed, but also in terms of redesigning existing applications for being more efficient and powerful…

Zero copy technologies such as PF_RING ZC allow applications to read packets in memory without any actor involved, being it the kernel or a memory copy. This is the reason why using…

We have already discussed on the first and second part of this post some common issues that might be encountered while doing high-performance packet processing. Most of the problems are related to…

Since the introduction of PF_RING ZC (Zero Copy), we have received many inquiries about migrating from DNA/LibZero to ZC. Said that at the moment we do not plan to discontinue DNA/LibZero, we…

NOTE: The new PF_RING home is hereAfter almost 18 months of development, we are pleased to announce the release of PF_RING ZC (Zero Copy). Based on the lessons learnt with DNA and…

Below you can find an excerpt of the "Suricata (and the grand slam of) Open Source IDPS" article written by our friend Peter Manev (Suricata core team) describing how to install and…

Introduction For years network adapter manufacturer companies have educated their customers that network monitoring applications can't live without hardware packet timestamps (i.e. the ability for the network adapter to report to the…

Some time ago, we discussed on the first part of this post, why not all servers spot the same performance with DNA. The conclusion was that beside the CPU, you need a…
