Hi,
Thanks for your reply, I check the spec and now know the "OFPCR_ROLE_EQUAL" and "Master/Slave"
I think my question is focus on Ryu controller, Our OpenFlow switch is OF 1.2 compatible...so my questions;
1. Ryu controller only support Master/Slave model? or ryu controllers can play equal role?
2. in Master/Slave mode...If master leave, then one of slaves become new master, what could be happen in OpenFlow switch? the new master insert flow tables start from scratch? old flow tables belong to old master will be deleted?
Thanks, hope not trouble you too much

Are you talking about generic Openflow spec?
If so, please see the spec,
OF 1.3.1 6.3.4 Multiple Controllers
The answer would be, yes, no and, no.
I can be wrong because I haven't checked the details of the spec.
