Hello Ryu Team,
Thanks for response, but How to analyze sequence number?
In other word, how to extract sequence number of ICMP pkts? There are some API
functions in RYU to do that?
I would like an algorithm like this: IF(sequence_number==1) THEN action1, etc.
Thanks.
Maurizio.

Oggetto: Re: [Ryu-devel] How to differentiate different ICMP Sequence Number
Pkts in Ryu controller?
Hi,
AFAIK, OpenFlow 1.3 does not provide match fields for identifying the
sequential ICMPv4 packets.
The match fields related to ICMPv4 packets are:
OFPXMT_OFB_ICMPV4_TYPE = 19, /* ICMP type. */
OFPXMT_OFB_ICMPV4_CODE = 20, /* ICMP code. */
If you want to do the different actions for each ICMP packets, i think you need
to 1. send all
ICMP packets to controller, 2. analyze sequence number and generate actions at
your RyuApp,
3. then, send packets to your switches by Packet-Out messages, for example.
Thanks,
Iwase
