P4: Programming Protocol-Independent Packet Processors 摘要 P4是一门高级语言,用于编程与协议无关的数据包处理器.P4与SDN控制协议相关联,类似与OpenFlow.当前,OpenFlow明确指定了运行的协议头.这个设置在几年内,从12个字段增长到41个字段,并且增加了协议头的复杂性,却没有提供应有的灵活性.本文提出P4作为OpenFlow将来演化发展的目标.我们有三个目标:(1)字段可重配性(2)协议独立性(3)目标无关性. 1 引言 S…

Navigating a Data Hierarchy with Table Views 导航数据表视图层次 A common use of table views—and one to which they’re ideally suited—is to navigate hierarchies of data. A table view at a top level of the hierarchy lists categories of data at the most general l…

2017 P4 中国峰会 北京 本次会议依然侧重介绍P4,并highlight P4的benifit,大致分为以下几类: 1.学术界 - 未来网络的发展,为何提出P4技术? 未来网络和实体经济.其他学科相结合 P4是可编程网络的助力器,其作用是将网络功能.协议设计交付给广大设计者而不是传统的网络设备厂商,从而 最大化地加速网络创新 缩短协议部署周期 开发者自顶向下网络设计,拥有完整的创新实验平台 2.互联网公司 - P4能为我们带来什么? 构建需求.业务驱动网络: DC网络数据实时收集 承载大流…

一 文章名称:SNAP: Stateful Network-Wide Abstractions for Packet Processing 数据包处理的带状态网络概念 发表时间:2016 期刊来源:SIGCOMM'16 解决问题: 一如何通过编程高效地.正确地管理带状态.分布式系统(提出SNAP).SNAP提供一个简化的带状态程序模型,开发者可以通过它在一个相对高层的交换机上进行开发项目.这些项目包括有全局读写.永久数组,故开发人员可以开发从带状态防火墙到细粒度流量监控的应用.SNAP编译器可以…

repo:Github PI P4Runtime - a control plane framework and tools for the P4 programming language 这个是P4社区目前正在开发的一个repo,根据它给的介绍,是一个控制平面的架构,提供了管理P4交换机的工具.接下来持续跟进它. 首先要安装相关依赖: sudo apt-get install libjudy-dev libreadline-dev git submodule update --init --r…

Introduction P4 is a declarative language for expressing how packets are processed by the pipeline of a network forwarding element such as a switch, NIC, router or network function appliance. It is based upon an abstract forwarding model consisting o…
