For DevOps and SysAdmins supporting high-throughput networks, the Linux kernel networking stack is a known bottleneck. When you need to perform deep packet inspection at 10Gbps or 100Gbps, iptables or standard AF_PACKET capture methods will instantly throttle your bandwidth.
In this tutorial, we cover how to deploy Suricata (an open-source IDS/IPS) using DPDK on bare-metal servers to achieve zero-copy packet processing.
Key Takeaways:
The DPDK Architecture: Learn how DPDK pulls packets directly from the NIC via Poll Mode Drivers (PMDs), avoiding interrupt overhead.
Memory Management: Step-by-step commands to configure CPU affinity and allocate hugepages to prevent translation lookaside buffer (TLB) misses.
Suricata Compilation: How to compile Suricata from source to properly link against DPDK libraries.
Configuration: A walkthrough of binding interfaces using dpdk-devbind.py and configuring the DPDK section in suricata.yaml.
