Using Zero-Copy Ring APIs to Improve Performance of DPDK Pipeline-Mode Applications- Dharmik Thakkar

Using Zero-Copy Ring APIs to Improve Performance of DPDK Pipeline-Mode Applications - Dharmik Thakkar, Arm Inc. DPDK supports pipeline-mode applications. These applications have packet I/O and packet processing stages. Software rings are used to transmit/receive packets between these stages. In this presentation, I will talk about using zero-copy ring APIs to improve the performance of pipeline mode applications. This presentation will highlight the challenges involved when using zero-copy ring APIs and present the solutions to overcome these challenges. I will also talk about the effect of various configuration parameters (zero-copy ring size, packet burst size, etc.) on throughput, memory bandwidth, cache eviction, and IPC. For more info about DPDK, the Data Plane Development Kit that consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures, see: https://www.dpdk.org/
