Not only does this allow us to stop reinventing the wheel, we can take advantage of the the improvements the FreeBSD community will bring in the future. After evaluating several plans we finally determined to port FreeBSD's (11.0 stable) TCP/IP stack into F-Stack. Continuing to develop and maintain a complete high performance network stack would have been too expensive. But our initial TCP/IP stack couldn't meet the needs of these services. Meanwhile, F-Stack was continuing to improve, being driven by our business growth, and, ultimately developed into a general network access framework. With the fast growth of Tencent Cloud more and more of our services needed higher network access performance. And then we developed a user-space TCP/IP stack called F-Stack that can process 0.6 million RPS with a single 10GE port. It's capable of achieving up to 11 million QPS with a single 10GE port and 18.2 million QPS with two 10GE ports. ![]() The reason is DPDK provides ultra-high performance and can be seamlessly extended to 40G, or even 100G NIC, in the future.Īfter several months of development and testing, DKDNS, high-performance DNS server based on DPDK officially released in October 2013. After several rounds of investigation we finally chose to develop our next generation of DNS server based on DPDK. We faced several options: one is to continue to use the original network stack in the Linux kernel, another is to use kernel bypass techniques. To deal with the increasingly severe DDoS attacks the authorized DNS server of Tencent Cloud DNSPod switched from Gigabit Ethernet to 10-Gigabit at the end of 2012. ![]() Provide an Epoll/Kqueue interface that allow many kinds of applications to easily use F-Stack.Various applications with stateful applications can easily use F-Stack to get high performance without processing complex asynchronous logic. Easy to extend with multi-process architecture.Support Nginx, Redis, and other mature applications.This greatly enhances network performance. Transplant FreeBSD 11.01 user space stack, which provides a complete stack function, and cut a great amount of irrelevant features.Ultra high network performance which the network card can achieve under full load: 10 million concurrent connections, 5 million RPS, 1 million CPS.Within various techniques, DPDK has been widely used because of it's more thorough isolation from kernel scheduling and active community support.į-Stack is an open source high performant network framework based on DPDK with the following characteristics: Furthermore, kernel bypass can achieve higher performance with multi-optimizing methods. ![]() Therefore, kernel bypass can avoid performance bottlenecks caused by kernel packet copying, thread scheduling, system calls, and interrupts. The main idea of kernel bypass is that Linux is only used to deal with control flow all data streams are processed in user space. There are various similar technologies such as: DPDK, NETMAP and PF_RING. Kernel bypass has emerged to catch more and more attention. Yet, the increasing demands of the Internet's growth demand a higher performant network processing solution. With the rapid development of Network Interface Cards the poor performance of data packet processing with the Linux kernel has become the bottleneck in modern network systems. ![]()
