Description
Today, most virtualized functions rely on the Data Plane Development Kit (DPDK) in user space to achieve high data plane packet processing and bypass kernel processing. The XDP ( eXpress Data Path) is an eBPF based high performance data path merged in the Linux kernel since version 4.8. The idea behind XDP is to add an early hook in the receive path of the kernel, and let a user supplied eBPF program decide the fate of the packet.
The central activity in this project is to compare DPDK and XDP data plane performance, using standard benchmarking methods which are the main focus of the ViNePerf Project. Additional development will be required to configure and automate the testing for XDP. Many benchmarking tools used today are DPDK-based, so we seek alternatives for a complete XDP-based test architecture.
Some key questions to answer are:

Based on the duration of the Internship, the seven objectives above will be allocated to a time-line (with some slack for delays, outages, etc.)
Anuket ViNePerf
Graduate program preferred, but a high-performing person near the end of their Undergraduate work may be suitable.
Linux and Linux Kernel. Some experience with data plane performance testing is desirable. Languages: Python 3, others.
This will likely be an area of continued research and development in the ViNePerf project, as we seek to maximize applicability to new technologies for Cloud Networking.
Part-time, 20 hours a week for 24 weeks. If the selected Intern prefers, this can be a full-time arrangement with 40 hours per week (3 months).
