Is there any default packet traversal in Ryu framework

Hi,
I use Ryu framework for controlling a simple network included 3 switches and 5 hosts with tree topology that i implemented in mininet.
I have packet_in_event to my controller from switches that haven’t miss table flow entry, why?
Also, I have packet_in_event to my controller even when I don’t generate any traffic to my network, why? Is there any packet traversal in Ryu framework in default? If yes, how can I ignore this packet traversal?

Writing my first ryu application

Hi,

I'm currently learning how to write my first ryu application and i've trouble understanding how to write it. So far i've look into the ryubook and the ryu development team booklet but still couldn't understand how it works.

Do you guys have a video or better explanation on the code and framework to guide me for my better understanding. 

Thanks and Regards,
Kelvin

What's the result if more than one class receive PacketIn ?

Hi, Dear all;
    
    When i read the source code of SimpleSwitch, i found that the function which call the  <at> set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER) will receive PacketIn message. My question is what's the resule if i use more than one function to call the <at> set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER) . Does all of them will receive the copy of PacketIn message ?

Best regards,
Vinllen

RV: Ryu_router help me

hello

I´m checking "Ryu SDN framework, release 1.0" and I’m working fine with it’s firewall app described in chapter 9.

But

I´m trying to simulate an SDN environment in Mininet with Ryu controller and use a router(L3 switch OpenFlow) that can be set using REST.

I´m trying to use the router described in "Ryu SDN framework, release 1.0" chapter 10

I followed all the steps correctly,

I get all the result like the picture of the book shows when I´m configuring the address, the default route and the static routes.

BUT

when I’m verifying the setting in each router with the command:

curl http://localhost:8080/router/0000000000000001

curl http://localhost:8080/router/0000000000000003

curl http://localhost:8080/router/0000000000000002

It only shows the "address" settings, it doesn´t show the "route" setting (route_id, destination, gateway)

And of course the hosts can´t do ping with each other

what am I doing wrong?

If you have another idea about using a router with Ryu, please help me, thanks

static router in ryu

Hi, Dear all:

    I'm new to ryu. I want to use ryu to send the static router from controller to openflow hybrid switch which support openflow1.3. As i following the source code, i found there is a api named rest_router.py which i can use to send the static router. 

    My question is how does the ryu send the static router to openflow hybrid switch, does it also use PACKOUT message in openflow.

    Could anyone help me ? Great appreciate for anyone's reply.

Best regards,
Vinllen
