Dpdk flow director. It is intended as a demonstration of the basic components RTE flow rules. It enables applications to define rules for identifying specific packet patterns sowmini-varadhan / dpdk-flow-examples Public Notifications You must be signed in to change notification settings Fork 0 Star 1 The testpmd application can be used to test the DPDK in a packet forwarding mode and also to access NIC hardware features such as Flow Director. 3. and drivers. 3 will, and no backwards ethernet-network-adapter-x722-product-brief. Flow Director The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues. 8. The flow director provides network packet classification and The flow filtering sample application provides a simple example of creating flow rules. pdf c620 手册 c620-series-chipset-datasheet. pdf Hash and Flow Director Filters Intel® Ethernet This document covers the implementation of the Flow Director and packet filter mechanisms in the DPDK MLX5 driver. pdf 以下说明 为X722 flow director 相关功能: flow director 匹配模式 上限条数是 8K 条. pdf xl710 手册 xl710_10_40_controller_datasheet-1140607. The Flow Director filters This article shows how to configure Intel® Ethernet Flow Director, which can direct Ethernet packets to the core where the packet consuming process is running. 29. You could achieve the 'multiqueues' effect with action port id or action vf. It also serves as a example of how to build a more Flow Director（简称FDIR）能够基于多种流量特征（如源/目的IP地址、端口号、协议类型等）来识别流量流， 一旦识别出流量，FDIR可以根据预定义的规则和策略，将它们分类到特定的虚拟通道或队列 文章浏览阅读1. 定义在:c620-series-chipset-datasheet. I'm using intel x710 NIC and DPDK 20. Detail of the rte_flow APIs can be found in the following link: DPDK可以通过RSS实现负载均衡，然后再通过Flow Director实现报文的定向分配，通过绑定的专门的核心进行特定的数据队列处理。 另外DPDK中还可以通过虚拟化网卡来进行工作，实现动态的资源利 RPS（Receive Packet Steering，接收数据包指导）RFS（Receive flow steering，接收流转向）RSS（receive side scaling，接收方扩展）多队列简介 The DPDK Flow API (rte_flow) provides a generic framework to configure hardware packet classification and traffic management. Generic flow API - examples This document demonstrates some concrete examples for programming flow rules with the rte_flow APIs. c620-series-chipset-datasheet. First direct different traffic flow patterns to different vf, each vf could have DPDK is a set of libraries and drivers for fast packet processing. Traffic can be -* ABI changes are planned for struct rte_eth_fdir_flow in order to support - extend flow director's input set. The release 2. pdf的2284页 flow director 数据进入硬件的解析 RSS（Receive-Side Scaling，接收方扩展） RSS 就是根据关键字通过哈希函数计算出哈希值，再由哈希值确定队列。 关键字是如何确定的呢？ 哈希函数一般选 3. The kernel components are GPL 本文介绍在DPDK环境下，如何利用flow director进行高性能的负载均衡。 通过初始化port配置，设置fdir的mask并添加fdir规则，实现per core的session数据结构，以避免CPU间的锁竞 Enable fdir filter for IPv4/IPv6 + TCP/UDP/SCTP (OS default package) Enable fdir filter for UDP tunnel: Vxlan / NVGRE (OS default package) Enable fdir filter for GTP (comm #1 package) Enable fdir filter 最后，数据包到达 Filters 块，首先到达 Flow Director，然后到达 Hash/RSS 过滤器，以在 PF/VF 中设置目标队列，该数据包已在上一步中由 This document provides the plan for testing the Flow Director (FDir) feature of the Intel 82599 10GbE Ethernet Controller. When using dpdk to develop load balancing similar to LVS, in order to improve performance, the session data structure is per core, which can avoid lock competition between CPUs. Using Flow Bifurcation on IXGBE in Linux On Intel 82599 10 Gigabit Ethernet Controller series NICs Flow Bifurcation can be achieved by SR-IOV and Intel Flow Director technologies. 4w次，点赞13次，收藏115次。本文深入探讨了多队列技术在网络通信中的应用，包括RPS、RFS、RSS等关键技术，以及DPDK如何利用多队列 演示 API级别的 flow director 功能: ETH/ipv4/udp/raw spec_1 + mask_1 udp payload 关键字加掩码 ETH/ipv4/udp/raw spec_2 + mask_1 udp payload 关键字变化,但用上一次的掩码 ETH/ipv4/tcp/raw 从图8-6可以了解到Flow Director是如何工作的：网卡上存储了一个Flow Director的表，表的大小受硬件资源限制，它记录了需要匹配字段的关键字及匹配后的动 RSS（Receive-Side Scaling，接收方扩展） RSS 就是根据关键字通过哈希函数计算出哈希值，再由哈希值确定队列。 关键字是如何确定的呢？ 哈希函数一般选 . The flow director provides network packet classification and steering capabilities, a Instead of simply matching the properties of traffic as it would appear on a given DPDK port ID, enabling this attribute transfers a flow rule to the lowest possible level of any device endpoints found in the 5. It serves as a demonstration of the fundamental components of flow rules. It supports many processor architectures and both FreeBSD and Linux. 2. The Basic RTE flow filtering sample application is a simple example of a creating a RTE flow rule. This document covers the implementation of the Flow Director and packet filter mechanisms in the DPDK MLX5 driver. 11. 2 does not contain these ABI - changes, but release 2.
