尝试使用bmv2行为模型来跑p4实例. 原文说明: We have released a new version of the behavioral model, written in C++. Some targets already support this new model -in addition to the original version, p4c-behavioral. If you see a target with a bmv2 directory, it means th…

当sudo ./behavioral-moel时候会发生这个 这个时候记得要先在 p4factory目录下先执行一下这个 sudo ./tools/veth_setuo.sh 再去执行sudo ./behavioral-moel就没有问题了…

前言 本文是我运行P4社区于Github开源教程Tutorials中的P4 SIGCOMM 2015 Tutorial一些实战小结,Github链接: Github. 测试的例子:P4 SIGCOMM 2015 - Source Routing 实验环境: Linux,Ubuntu 14.04 64bit. 实验步骤: 准备工作: 安装 bmv2 和 p4c-bm: 请移步我的另外一篇博客: P4 前端编译器p4c-bm.后端编译器bmv2命令安装 make error问题 上面给出的博文中,还…

1.源码目录结构 P4项目源码可以在github上直接获取(https://github.com/p4lang).P4项目由很多个单独的模块组成,每个模块就是一个子项目,下面分别简单介绍一下各模块的功能. (1)behavioral-model 模拟P4数据平面的用户态软件交换机,使用C++语言编写,简称bmv2.P4程序首先经过p4c-bm模块编译成JSON格式的配置文件,然后将配置文件载入到bmv2,转化成能实现交换机功能的数据结构. behavioral-model模块是架构无关的,可以实…
