The Recursive InterNetwork Architecture area (RINA) develops the technology of the alternative TCP/IP in order to realize simpler and more powerful networks. Memory allocation. We then discuss kernel-bypass networking and programmable packet processing, including offloading to SmartNICs, to understand how the network stack is changing to meet the needs of contemporary. 网络,激发和修复内存瓶颈 (LSF Memory Management Summit, March 2017): 提供了许多 XDP 开发者当前所面对 内存问题 的许多细节。不要从这一个开始,但如果你已经理解了 XDP,并且想去了解它在页面分配方面的真实工作方式,这是一个非常有用的资源。. 40 35 30 DPDK Netmap DPDK Netmap 25 20 50 100 Zero copy Zero copy - Copying - Copying 150 200 Packet size (bytes) 250 300 Figure 3. 基于DPDK开发的高性能DNS授权服务器, 万兆网卡QPS可以达到千万以上, 支持将zone data存放到mongodb. org although as I hope is > clear from above DPDK is just our paticular test environment we > expect other libraries could be built on this interface. DPDK works on KVM guests with interfaces coming in from host OS either as Direct Passthrough [ Physical interface or Virtual interface (Virtual Function)], Emulated interfaces (e1000), and Virtio interfaces (with or without vhost backend support). We focus our measurements on OvS because it is the latest and fastest forwarding method based on the Linux network stack and the existence of the DPDK port allows for a direct performance comparison of the Linux network stack with DPDK. Figure 1: Integration of Data Plane Development Kit data plane with native Open vSwitch*. OvS switching ports are represented by network devices (or netdevs). how-to-install-dpdk-on-ubuntu. Posted January 27, 2012 · Add Comment. 1 (Feb 2016) "rebranded" Performance is primary focus and concern Yes, it is as fast as DPDK and netmap XDP is NOT kernel bypass Designed to work in concert with netstack "Just" an earlier packet processing stage. Getting the packet is still part of the battle. Affects throughput, delay, CPU util. Therefore, DPDK, netmap and more were developed to deal with this problem.
