传统方法无法应用到SDN中的原因: SDN 中的交换机功能太少. 作者提出: 使用控制器收集包和流的统计来判定包是否被修改, 交付路径是否正常; 并对该方法加以改进
mininet , ovs , ryu 分别进行源码安装
OVS安装
ovs与linux内核版本对应
OVS版本是需要与linux内核版本对应的,否则会导致内核函数与OVS调用的函数不匹配,简称装不上。

linux 内核版本查看uname -r
安装过程
这里要注意,如果下载的是官网的压缩文件,则不用./boot.sh直接从./configure开始即可, 如果是在github上下载的,则需要./boot.sh再configure

Magit的基本使用
Magit 的基本介绍
Magit是在emacs中对git的一种扩展, 它的本质是在emacs中, 利用emacs的方式调用git的命令, 使得git的使用更加地emacs化. 本人的emacs 能力有限, 因此只介绍magit中的一些最常用的命令, 方便日常使用够用即可. 要更加全面地研究可以看它的原网站.

Amplification Hell: Revisiting Network Protocols for DDoS Abuse.
Rossow C. Amplification Hell: Revisiting Network Protocols for DDoS Abuse[C]//NDSS. 2014.
本文重审各种基于UDP的协议,并分析哪些易用于RDOS,总结目前已被用作的RDOS和应对措施分析。本文主要有三总分组成:threat model,vulnerable protocols,realword attacks countmeasure。
LADS: large-scale automated DDOS detection system
Sekar V, Duffield N G, Spatscheck O, et al. LADS: Large-scale Automated DDoS Detection System[C]//USENIX Annual Technical Conference, General Track. 2006: 171-184.
本文提出LADS,根据轻量级和重量级DDoS检测优缺点进行分析提出两阶段检测法。首先检测是可能有异常,再通过流收集器进一步检测以决定是否发出警告。
A taxonomy of DDoS attack and DDoS defense mechanisms
Mirkovic J, Reiher P. A taxonomy of DDoS attack and DDoS defense mechanisms[J]. ACM SIGCOMM Computer Communication Review, 2004, 34(2): 39-53.
本文不错,就是老了点,对DDoS攻击和防御做了总结和分类,而不是提供个具体的方法。
DDoS Attack Protection in the Era of Cloud Computing and Software-Defined Networking
B. Wang, Y. Zheng, W. Lou and Y. T. Hou, “DDoS Attack Protection in the Era of Cloud Computing and Software-Defined Networking,” 2014 IEEE 22nd International Conference on Network Protocols, Raleigh, NC, 2014, pp. 624-629.

Fayaz S K, Tobioka Y, Sekar V, et al. Bohatei: Flexible and elastic ddos defense[C]//24th {USENIX} Security Symposium ({USENIX} Security 15). 2015: 817-832.
本文提出一种针对新型网络的DDoS的防御系统,通过SDN,将可疑流量通过VM以达到保护主机的目的。(本文目的是为特定主机提供保护服务,收费服务那种。)本篇的introduction和background都比别人难懂。。。
SD-Anti-DDoS: Fast and efficient DDoS defense in software-defined networks
Cui Y, Yan L, Li S, et al. SD-Anti-DDoS: Fast and efficient DDoS defense in software-defined networks[J]. Journal of Network and Computer Applications, 2016, 68: 65-79.
本文提出一种针对DDoS攻击的检测与缓解机制,由四部份组成:attack detection trigger,attack detection,attack traceback,attack mitigation。本文质量一般,不过packet_in trigger提出觉得有点创新。
FRESCO:Modular Composable Security Services for Software-Defined Networks
Shin S W, Porras P, Yegneswara V, et al. Fresco: Modular composable security services for software-defined networks[C]//20th Annual Network & Distributed System Security Symposium. NDSS, 2013.
本文提供了一个应用框架FRESCO,可供研究人员和开发代人员更简单地实现各种检测、缓解模块。
dFence: Transparent Network-based Denial of Service Mitigation
Mahimkar A , Dange J , Shmatikov V , et al. dFence: Transparent Network-based Denial of Service Mitigation[J]. Nsdi ’, 2007:24-24.,
本文通过添加dFence中间设备,实现透明的DoS防御。图1架构图,将中间设备透明插入可能受攻击的主机前并拦截所有流量。
