Hello Bill, Thank you for your response! The output is very similar to our requirement! Could you please tell me how the data field was populated? Thanks once again! Jibran > On Apr 9, 2017, at 12:57 AM, William Fisher > wrote: > > I'm not completely sure what you want to do. Do you want out

Re: [Ryu-devel] Decoding explicitly RYU messages

The data field is the packet data for the Packet-In message in hex. I took the data snippet from your message (with python string escapes) and entered the following in a python 2.7 interpreter: >>> data='\x00\x00\x00\x00\x00\x01\x00\x00\x00\x00\x00\x02\x08\x00E\x10\x00D\x84u@\x00@\x06\xa2,\n\x00\x

Re: [Ryu-devel] Decoding explicitly RYU messages

Hi, Jibran Sorry for cutting in. FYI, in RYU, you can decode your OpenFlow message like this: @set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER) def _packet_in_handler(self, ev): msg = ev.msg.to_jsondict() print(json.dumps(msg, indent=4)) And you can get: { "OFPPacketIn": {

Re: [Ryu-devel] ryu-manager can't load app from file which has same name as installed module

Hi Brad, Great! Thanks a lot! It looks almost good to me. A few remarks, if update sys.path before importing module file, I guess we need to backup the original sys.path and restore it before returning module instance as following. https://github.com/osrg/ryu/blob/master/ryu/utils.py#L96-L97

Re: [Ryu-devel] Adding functionality in Ryu

Hi, Currently Ryu is focus on using OpenFlow protocol to control dataplane. I think there is no specific OpenFlow message for power control. However, you still can use Ryu to do that, in my opinion, there are two options: 1. Modify your dataplane (e.g. WiFi AP), make it support OpenFlow, and ad

Re: [Ryu-devel] ryu-manager can't load app from file which has same name as installed module

Hi Iwase, You are quite right I forgot to copy that part of the code over. I have attached a refreshed patch that restores sys.path after a file is imported. Let me know what you think! Brad On 10 April 2017 at 14:22, Iwase Yusuke wrote: > Hi Brad, > > Great! Thanks a lot! > It looks almost
