1.利用Mininet仿真平台构建如下图所示的网络拓扑,配置主机h1和h2的IP地址(h1:10.0.0.1,h2:10.0.0.2),测试两台主机之间的网络连通性 2. 利用Wireshark工具,捕获拓扑中交换机与控制器之间的通信数据,对OpenFlow协议类型的各类报文(hello, features_request, features_reply, set_config, packet_in, packet_out等)进行分析,对照wireshark截图写出你的分析内容。 实验注意事项 来源: https://www.cnblogs.com/xzhcode/p/11853673.html

Why do H1 tags not need a class or id in the css?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I was just looking at my CSS and the h1 tag is defined like this: h1 { .... } When everything else either has an id "#" or a "." class preceding it. What is the reason header tags don't need this? Have I infact made a mistake and they do need one? 回答1: This means that all occurences of h1 will share the same style. Similarly, you can have a style defined for any other element, e.g.: p { font-family: Helvetica; } That means all p tags will use the Helvetica font. Note that it's also a best practice to have just one h1 element in a page. You

But I hope to know if there are other ways with better performance. 回答1: Here's what I did: I unstacked your dataframe into a longer format, then grouped by the name column. Within each group, I drop the NaNs, but then reindex

E.g: input: [[1,2,3],[5,6],[3,4],[1,7]] expected output: [[1,2,3],[5,6],[4],[7]] I know I can use the predicate sort/2 to remove duplicates in a single list, but how do I get it to work across multiple lists? 回答1: Here is my attempt. Hope you've made some attempts to solve it and learn from this...Anyway if you still didn't come up with anything take a look at the following code: remove_dupl ( InL , OutL ):- remove_dupl ( InL , [], OutL1 ),
