CNI-Agnostic Network Performance Accelerator with eBPF

Explore an eBPF-based network accelerator for Container Network Interfaces (CNIs) in this conference talk. Learn how the authors implement inner node TCP communication and KubeVirt network acceleration using eBPF technology. Discover the significant performance gains achieved, including up to 40% network throughput improvements and up to 50% lower latency across various workloads. Understand the method of attaching eBPF programs to virtual network interfaces and the optimizations performed, such as bypassing the kernel stack and enabling direct data transmission between sockets. Examine how these optimizations enhance network throughput and reduce latency in specific scenarios like edge computing, 5G, and KubeVirt. Appreciate the key benefit of this approach: its CNI agnosticism, allowing seamless acceleration without modifying underlying CNIs or networking setups. Gain insights into how operators and developers can easily enable this acceleration through simple deployment, regardless of the specific CNIs in use.
