DPDK Summit 2025

Niagara Networks provides high-performance, high-reliability network visibility and traffic delivery solutions for the world's most demanding service provider and enterprise environments.

Vitaliy will share Niagara Networks' experience in extending standard ASIC processing capabilities by integrating specialized hardware modules with DPDK applications into a single unit to support advanced functionalities such as:

- Packet and flow slicing
- Traffic deduplication
- NetFlow and IPFIX
- Packet data masking
- Packet RegEx search
- L7 application filtering
- TLS decryption
- GTP 3G/4G traffic correlation

To achieve this, Vitaliy will cover:

- Custom hardware utilizing Ethernet controllers from Intel
- ASIC-to-Ethernet controller backplane connectivity
- OS integration and provisioning for DPDK applications
- Performance and optimization strategies, including:
a. OS tweaks
b. BIOS optimizations
c. DPDK application architecture optimizations
- Testing and CI:
a. Custom framework development
b. CI implementation on test servers instead of final hardware

In this tech talk, we benchmark connection tracking implementations by extending rte_hash based tables with advanced flow aging mechanisms. We compare aging algorithms like timer wheels, smart periodic scanning vs. LRU tables.
We define test cases based on telco traffic profiles using T-Rex traffic-gen and interpret the benchmark results.
Join us to gain insights into enhancing DPDK rte_hash with flow aging features.
