openvswitch 修改dpid（datapath id）

<!--修改validate根据ID验证 --> <script type="text/javascript"> if ($.validator) { $.validator.prototype.elements = function () { var validator = this, rulesCache = {}; // select all valid inputs inside the form (no submit or reset buttons)

常常你会遇到这样的情况,需要自增长的起始值是 0,再次从 0开始. 两个选择: 1. drop table_name; django重新建表. 2. ALTER TABLE table_name AUTO_INCREMENT=66666; 好吧,我一直粗暴解决问题了很久,NO.2方法明显优雅许多~ 今天群里朋友问起来了,顺便一下啊 django - 修改 自增长id,起始值

在对OpenFlow协议有了一定了解以后,开始尝试如何通过Ryu控制器实现网络中的通信.根据协议,我们知道,当数据信息首次传输到交换机时,由于交换机不存在该数据信息所对应的流表,因此,会触发PacketIn消息,即交换机会将数据信息打包后,通过相应的交换机-控制器的专用通道将数据信息描述之后,传输给控制器,控制器在对数据包进行解析之后,根据相应的逻辑(基于底层网络协议),给交换机添加相应的流表,在这之后,数据包会根据新添加的流表传输给下一个交换机或者目的地址. 下面给出相应的交互流程: 从图中可

一.switching hub by openflow: 用Ryu实现一个有如下功能的switching hub. ? Learns the MAC address of the host connected to a port and retains it in the MAC address table.? When receiving packets addressed to a host already learned, transfers them to the port connec
