我们在使用控制器的时候,有时候会想知道Packet In的速率。借鉴于Ryu拓扑发现模块的设计思路,我们可以把测量Packet In速率也作为一个模块。测量Packet In速率算是测量控制器性能的一种方式,扩展一下,我们可以在这个模块里添加其他用于测量控制器性能的功能。这里我们参考全球SDN测试认证中心发布的白皮书[1],可以添加一些里面的功能。模块设计思路在ryu/ryu目录下创建packet_目录,里面包含如下核心文件:dump.py作为应用文件,将packet_in.py里的Packe »

How to use DPDK to implement DNS Spoofing

Similar to How to use DPDK to implement ICMP Spoofing, we can build DNS packets to achieve DNS Spoofing. In this scenario, DPDK need get the domain name from DNS query and send the response.Ethernet, IP and UDP header build remains the same because »
