7 Installing and Configuring DPDK for Session Monitor

This chapter provides instructions for installing and configuring Data Plane Development Kit (DPDK) for the Oracle Communications Session Monitor to monitor high volume of network traffic.

DPDK provides sniffing performance for some of the Intel network cards and network traffic patterns. If you have a compatible network card, you can enable DPDK.

Note:

See Oracle Communications Session Monitor Release Notes to verify if you need to update DPDK. If you need to update DPDK, verify if the DPDK requires latest Oracle Linux Platform.

DPDK is a special architecture supported by specific network card designs, drivers, and server architectures, that improves performance when processing network traffic. For high network traffic monitoring, you can select to enable DPDK option on Session Monitor Probes. DPDK uses NUMA architecture special feature to have faster access to traffic written from a Network Card and to enhance the performance.

DPDK architecture involves two parts for Session Monitor Probes. The daemon is responsible for network traffic analysis (rat) is compiled against a specific DPDK library, and is deployed upon Session Monitor installation. For DPDK to work, the DPDK driver must be downloaded and installed on the Probe, as well.

Note:

To install DPDK on a SELinux enabled machine, disable SELinux first and install DPDK. Enable SELinux after the installation of DPDK.
