Hallo ryu - development list, I allready ask this question at the ovs-discussion list, but unfortunatelly nobody answer. I try to implement an OpenFlow controller with a special Update algorithm, which is called WayUp and is discribed in this paper: https://www.net.t-labs.tu-berlin.de/~stefan/hotnets14update.pdf . My test environment consists of a mininet VM with ovs as switch and ryu as controller. The update consists of several rounds. In every round several messages are send from the controller to the switches. One message causes the switch to install one forwarding rule. Openflow messages of round n have to be send to the switches and processed by the switches befor messages of round n+1 can be send. That means a switch have to install a rule of round n and forward packet according to this rule before the controller can send messages of round n+1. The controller have to wait till the switches install the rules of round n after it can send the messages of round n+1. Can I use barrier requests to implement this behavior? When is a barrier reply send exactly?
