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,

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
