????: [Ryu-devel] Mininet connecting to RYU controller
I start RYU controller which opens TCP listening port 6633.Now I connect my
mininet topology to the controller port 6633.My mininet topology consists of 6
switches.Hence there will be 6 connections one from each switch to the RYU
Controller port.
Now I bring down my controller and start the controller again.
I find that all the switches in my topology can talk to the controller as if
the controller process were never killed.
This is not how I understand a TCP connection between a server and a client.If
the server goes down I would expect the connection to be disconnected.
This set of connections seem to survive a server process restart.Can someone
explain how this is happening?I am just curious
Thanks & Regards,
Karthik.
