Abstract
A network of switches that forwards network packets between end hosts may be controlled by a controller. The controller may maintain information that identifies subsets of the end hosts that are associated with respective broadcast domains. The controller may configure the switches in the network to identify broadcast network packets and to forward the broadcast network packets to the controller. The controller may identify which broadcast domain is associated with a received broadcast network packet based on information such as source information retrieved from the broadcast network packet. The controller may identify switches that are coupled to the end hosts of a broadcast domain associated with the received broadcast network packet. The controller may forward the broadcast network packet to the identified switches through network control paths and may direct the identified switches to forward the broadcast network packet to end hosts of the associated broadcast domain.
