Fast QUIC sockets for cloud networking

Using vector packet processing for QUIC acceleration and offload
H.1308 (Rolin)
QUIC was introduced by Google to move the transport protocol implementation out of the kernel, and is now being standardized in the IETF. It provides both encryption and multiplexing, and will be the default transport for HTTP/3. In this talk we'll present the work we've done investigating whether QUIC would benefit from vectorized packet processing, the impact it has on performance and how it can be consumed by external applications. VPP (vector packet processing) is a fast network data plane, part of the Linux Foundation FD.io project providing fast network functions on top of DPDK. It provides an optimized support of TCP & UDP allowing significant performance improvements. In this presentation, we'll discuss: How we took advantage of the open source protocol implementation quicly and vpp's hoststack, to implement fast QUIC sockets. How this can be consumed by external applications and to what ends. What this enables regarding hardware and software offloads.

Many people and companies are betting that cloud-native networking will be the preferred way of implementing network functions in an easy and scalable way. It is based around the tenants of modularity, high availability, scalability, low-overhead networking, and ease of deployment. And a number of companies such as Google has shown that it is really possible to achieve these properties with it. But the architectural basis of cloud-native is quite different from the ones of virtualization-based ...

As CoSP’s accelerate their adoption of SDN and NFV technologies, the increased need for metrics, performance measurement and benchmarking becomes a focus, to ensure the continued delivery of “best in class” services. As NFV environments have grown in size and complexity, the tools required to gain this greater visibility into the NFVi need to continue to evolve to meet the requirements for manageability, serviceability and resiliency. Using Collectd as a metrics collection tool, OPNFV ...

The Linux kernel networking capabilities have been undergoing major changes over the last years. At the heart of the performance gain, eBPF (extended Berkeley Packet Filter) and XDP (eXpress Data Path) have brought new possibilities in terms of tracing and network packet processing. eBPF is a trendy topic in the Linux world, and today it needs little introduction among the SDN and NFV community. But the technology is still under heavy development, bringing new features, more flexibility, and ...

One of the challenges of doing software network applications is observing the inputs, outputs, and what the application is doing with them. Linux provides a rich tool set with eBPF but integrating this into a DPDK application is challenging. The DPDK libraries for capturing is incomplete which leads to lots of time debugging the tools. This talk addresses these issues, recommends solutions and proposes enhancements to make developers live easier.

XDP support is an increasing trend on the network devices. XDP main goal is processing packets at the lowest point in the software stack avoiding overheads. Memory recycling of received buffers achieved through the in kernel pagepool API plays a fundamental role in the increased performance. Adding XDP support on a driver can be non-trivial. In this talk we'll demonstrate how porting a standard ethernet driver (mvneta/netsec) to XDP and the pagepool API can boost performance. Part of the ...
