笔记是边读边写的旁注,比较乱,没有整理就丢上来了. 可以说不仅要说fast packet process servey,也同时是一篇packet process的综述了.packet processing,放在传统协议栈的视角中看,也就是L2.L3的一个小部分,但是细看,里面也是有特别多的内容的,在这一小点上深究,也有特别大的意义. Introduction Intent的流量水平上去了,而且一直都是增长的势头:网卡硬件的速度上去了(在如今的数据中心,网口都有40Gbps的速率):pkt pro…

SIGCOMM17 摘要 在现有的网络测量任务中包括流量监测.数据收集和一系列网络攻击的预防.现有的基于sketch的测量算法存在严重性能损失.大量计算开销以及测量的精确性不足,而基于硬件的优化方法并不适合sketch.为了完成这些任务,设计了一种基于纯软件包转发的网络测量框架,并改进现有算法提出了两种算法.这个网络测量框架具有高性能(line-rate).高精度.广泛性(适用于多种sketch算法).自动化(自动调节负载)的特点.框架包括数据平面和控制平面,每个软件交换机对应一个数据平面,每个…

COMST 2018 主要内容 这是一篇有关快速包转发的综述,先介绍了包转发的有关基础知识和背景,具体介绍了包转发的主流方法,对这些方法进行了细致详尽的比较,最后介绍了最新的方法和未来的研究方向. 包处理包括Fast Path 和Slow Path,前者用于包转发和包头处理,后者主要用于管理.错误控制.维护. 主要的方法有三种:纯软件.纯硬件.软硬结合. 纯软件方法主要在软件层面(零拷贝.批处理.并行性.用户/内核空间)进行性能优化,性能不足的主要是因为网络协议栈架构的不足. 纯硬件方法性能高但…

VPP简介 VPP(Vector Packet Processing)是思科旗下的一款可拓展的开源框架,提供容易使用的.高质量的交换.路由功能 特点:高性能.运行在普通的cpu上. 优点:高性能.技术成熟.模块化.灵活性,有丰富的特征集. 可以允许任何人插入新的结点无需改动内核代码. 模块化.灵活性.可延展性 VPP构建基于"包处理图",意味着可以"插入"新的结点,变得容易拓展,可以自定义一些特定的功能. 插件如何运行:运行时,VPP平台从RX rings抓取所有可…

前言 VPP提供了一个配置工具,让用户可以简单快捷地配置VPP.用户可以通过一些简单的命令配置VPP,功能包括安装及一些基本配置和测试用例. 使用 先安装一个python的pip模块,使用pip安装VPP的配置工具. 如果不确定要如何配置,可以选择默认值:y ,而对于数字,如果问题中有形如[1024]的样子,则1024就是默认值. 在Ubuntu系统下安装运行 安装pyhton的pip $ sudo -H bash # apt-get install python-pip Reading pac…

摘要: 尽管可编程NIC可以提供更好的可扩展性以处理不断增长的网络工作量,但为硬件中的有状态网络功能编程提供表达能力却又简单的抽象仍然是一项研究挑战. 我们使用FlowBlaze解决了这个问题,FlowBlaze是一种开放式抽象,用于在硬件中构建有状态的数据包处理功能.该抽象基于扩展有限状态机(EFSM),并引入了流状态的显式定义,从而允许FlowBlaze利用流级并行性. FlowBlaze具有表现力,支持各种复杂的网络功能且易于使用,对程序员隐藏了底层硬件实现问题. 我们在NetFPGA S…
