Re: [integration-dev] Parsing open-flow packet and decoding the type of the message
Hi Michal,
I checked Openflow java’s Simple-Client sample program but I could not find the API that decodes the received message from socket to respective openflow messages.
Let me know if I’m missing something here.
Thanks & Regards,
Raksha

Hi Michal,
Yes, I want to use openflowjava to parse/decode the openflow messages. The code referred in my previous mail is the understanding so far of how that could be done. Am I going in the right direction here? If so, what is the best way to convert the byte array of openflow message received from Java sockets to OfHeader type?
Thanks & Regards,
Raksha

Hello Raksha,
what code do you refer to ? Do you want to use openflowjava for parsing / decoding openflow messages ?

Hi,
I would like to parse/decode the openflow packets received from Java sockets. The received openflow packets are in byte[] format and as far as I could understand, it should be converted to OfHeader.
OfHeader ofheader = (OfHeader) msg
if ( ofheader instanceof FlowRemovedMessage ) {
LOG.info("FlowRemoved received\n");
} else if ( ofheader instanceof HelloMessage) {
LOG.info("Hello reply received\n");
} else if ( ofheader instanceof ErrorMessage) {
LOG.info("Error message received\n");
}
}
1. Is the above approach right to decode Openflow packets?
2. What is the best way to convert byte[] received from Java sockets to OfHeader?
Thanks & Regards,
Raksha
