Thanks, Ben, I appreciate your help very much.Is there any documentation or schematic diagram that describes the process that a packet entering the switch's input ports, scheduling, and departing from the switch's output ports? Or there is no such stuff in OVS? Cheers, Jfhu> Date: Tue, 6 Mar 2

Thanks, Ben, All right. However, at least there is a mapping from the software implementation of a switch to its real component. Is that right? For example,The struct, dp_netdev, may be mapped to a switch, because of following mappings:1. member struct dp_netdev_queue queues[N_QUEUES] correspo
