Ryu supports both. However, Ryu doesn't know what you want. IOW, you need to implement an application to set roles in a way that you want. IIRC, this sample code uses Zookeeper to track liveness of controllers. When a controller is dead, the rest of controllers get notification. Then your application need to configure roles. > 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? It's up to switch configuration, IIRC. ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
