将流推送到 Floodlight 控制器

Question

我正在尝试在 FloodLight Controller V1.2 中推送流，并在 V0.9 中尝试过

我已经使用Mininet添加Switched

mn --topo=tree,2 --controller=remote,ip=192.168.0.107,port=6653 --switch=ovsk,protocols=OpenFlow13

它使用 3 个交换机和 4 个主机创建拓扑

H1, H2  S2  S3  S1  H3, H4 

我正在使用 curl 命令将流添加到每个 Switch

// Pushing flows on switch 2 and switch 1

curl -X POST -d '{"switch":"00:00:00:00:00:00:00:03", "name":"flow-mod-1", "cookie":"0", "priority":"32768", "in_port":"2","active":"true", "actions":"output=3" }' http://localhost:8080/wm/staticentrypusher/json

curl -X POST -d '{"switch":"00:00:00:00:00:00:00:03", "name":"flow-mod-2", "cookie":"0", "priority":"32768", "in_port":"3","active":"true", "actions":"output=2" }' http://localhost:8080/wm/staticentrypusher/json

curl -X POST -d '{"switch":"00:00:00:00:00:00:00:02", "name":"flow-mod-3", "cookie":"0", "priority":"32768", "in_port":"2","active":"true", "actions":"output=3" }' http://localhost:8080/wm/staticentrypusher/json

curl -X POST -d '{"switch":"00:00:00:00:00:00:00:02", "name":"flow-mod-4", "cookie":"0", "priority":"32768", "in_port":"3","active":"true", "actions":"output=2" }' http://localhost:8080/wm/staticentrypusher/json


// adding flows in Middle switch S3 which is connected to S1 and S2

curl -X POST -d '{"switch":"00:00:00:00:00:00:00:01", "name":"flow-mod-5", "cookie":"0", "priority":"32768", "in_port":"1","active":"true", "actions":"output=2"}' http://localhost:8080/wm/staticflowpusher/json

curl -X POST -d '{"switch":"00:00:00:00:00:00:00:01", "name":"flow-mod-6", "cookie":"0", "priority":"32768", "in_port":"2","active":"true", "actions":"output=1"}' http://localhost:8080/wm/staticflowpusher/json

并且流已成功添加。

我什至可以从 H2 ping 到 H4，反之亦然

问题是当我看到拓扑时

它不再连接了。

拓扑更改为

H1, H2 S2

S3

S1 H3, H4

花了一些时间，但我使用此链接找到了解决方案

感谢 Ryan Wallner 的 QoS 实施。

下载代码后转到Floodlight/app/qos/

pythons 脚本在 Controller 中添加流的位置。

注意： 以上流程是为了帮助您了解流量推送的工作原理。如果你不想这样，你可以直接使用下面的 curl 命令。

我刚刚完成了一些日志记录，并获得了以下格式，通过运行 python 代码在每个 Switch 中添加流。

我假设有问题描述的拓扑

对于每个开关，我们需要推送 4 个流 Forward, Reverse, ForwardARP, ReverseARP

添加流量后，ping 将开始工作。有关更多详细信息，请阅读服务质量链接。
