about your first question, you can schedule events with some time delay using this method:

About your second question, I would suggest you try to find some related papers and contact their authors.

> Hi everyone, i am new to NDNSim and facing some issues regarding broadcast storm problem and merger of SDN with NDN. First of all, let me describe my scenario. Suppose i have a Node 0 which has two neighbor nodes (Node 1 and Node 2). When a interest packet is forwarded by Node 0, it received by both nodes. Now according to my understanding and logging  Node 1 processing starts first. After that in forwarder class it sends packet through OnOutgoingInterest function. Then, Node 2 starts its processing by running forwarder class and when this process finish a new interest is received from Node 1 to Node 2 which was previously forwarder by Node 1 to its neighbors. Now my first question is, how can i stop processing of each node till a fixed time and this process should be done on both sides (Node 1 and Node 2)simultaneously? And my second question is related to SDN which is how can we implement SDN controller in NDNSim?
