摘要:
A network device is connected to another network device over a network and performs multicast transmission and reception over the network. The network device stores in a storage unit in a corresponding manner a drop address that uniquely identifies data to be dropped from the network and control data that indicates whether dropped data is to be forwarded or deleted. The network device drops the data based on the drop address, and then either forwards or deletes the dropped data based on the control data.
