Hello experts, I have two questions for the flow installation in ODL.
1. Say, an ODL receives a *PACKET_IN* message for the installation of flow and the path for the flow spans *N* switches. In this case, does (A) ODL sends *FLOW_MOD *in a parallel manner to all *N *switches OR (B) sends FLOW_MOD only to the switch from which it received a *PACKET_IN *message so that it sends *N FLOW_MOD* messages? 2. From the example in 1), if *N *switches are managed by different *Master *instances*, *the RPCs between Master instances for parallel installations are required (as in 1-(A)) or not (as in 1-(B))? Thanks in advance. Dongeun Suh.
