Hi Folks, Can I use ryu controller to extract a specific value(field) from an IP packet of S1AP protocol ?
I am attaching a wireshark trace and in the trace, it has IP packets of S1AP protocol and in the packet with info as "InitialContextSetupRequest" has the TEID to be used. If you expand it, under the S1 application protocol section >> In ITEM 3 you can see the TEID to be used. I need this TEID to be used for a later flow action. Is such a feature of extracting a particular data from a packet, storing it and then using it for subsequent use possible via ryu controller? Best Regards, Ashish Kurian
