[Ryu-devel] [PATCH] Modify ryu.topology to recognize and send switch re-connection events, and to handle cases where _get_switch() returns None

In response to a request on this mailing list from Zhao Jun, here’s a patch that: 1) Creates an EventSwitchReconnected class for ryu.topology 2) Sends said event at the appropriate time 3) Handles the case, for the DEAD_DISPATCHER state, where the _get_switch() method returns None. Signed-off-by

Re: [Ryu-devel] [maybe a bug] dpset : multiple connections

Yes, I noticed that topology is intended to supersede dpset. The reason why I use dpset is that I did not find any event related with reconnected in topology module. The reason why I want to handle reconnected event is that I have ryu controller in Oregon US, and many switches located around the

Re: [Ryu-devel] [maybe a bug] dpset : multiple connections

One more thing occurs to me... It appears you're using both dpset and topology. If I understand things correctly, topology is intended to supersede dpset. So - using both together may not be quite what you mean to be doing. Nevertheless... I have a forthcoming patch (in testing) that is intended

[Ryu-devel] Sequential Operator

Hello, I recently became familiar with SDN using Pyretic. Using Pyretic, I had an sequential operator which I found useful for chaining controller applications together (i.e., packets first had to flow through a firewall application before a mac-learning switch could process them. I've recen

[Ryu-devel] Help: CPqD user switch NAT service

Hi All , In my Mininet test I have used Ryu as a controller and CPqD user switch. The problem that I have faced that hosts can not access the Internet (NB: --nat option is already used). However it works fine using OVSKernelSwitch. Do you know how we can activate or use NAT service (to allow hosts
