![]() Within various techniques, DPDK has been widely used because of its more thorough isolation from kernel scheduling and active community support.į-Stack is an open source network framework with high performance based on DPDK, include an user space TCP/IP stack(port FreeBSD 11.0 stable), Posix API(Socket, Epoll, Kqueue), Progamming SDK(Coroutine) and some apps(Nginx, Redis) interface. ![]() Furthermore, kernel bypass can achieve higher performance with multi optimizing methods. Therefore, kernel bypass can avoid performance bottlenecks caused by kernel packet copy, thread scheduling, system calls and interrupt. ![]() 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. I red about netmap which allows user programmers to access packets in the user space, that means user applications can read / send network packets very quickly using this netamp. There are various similar technologies appear, such as DPDK, NETMAP and PF_RING. You actually have to recompile the kernel with device netmap added in your. However, the rapid development of the Internet needs high performance of network processing, kernel bypass has caught more and more attention. on: Why do we use the Linux kernels TCP stack FreeBSD Netmap user here. But for PASTE, please enable TX checksum offloading. With the rapid development of NIC, the poor performance of data packets processing with Linux kernel has become the bottleneck. As explained in netmap usage, disable all the offload settings.
