We need notificaiton from storage. The datapatch connets to ryu then ryu subscribes to the storage about the changes to the datapatch. > dpset: This tracks what datapaths are connecting to Ryu. > At the time when datapath connecting to ryu, the network id might > not be known.

The status should be separated. Anyway, as I wrote before, I try the straight conversion. It's not the good time to change the data structures. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Ryu-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ryu-devel
