Topology Stratification Method and Apparatus, and Flooding Processing Method and Apparatus

摘要

The method includes the following steps. First, a controller receives a data packet that is reported by a switch connected to a source host; then the controller searches a local media access control (MAC) address table of physical addresses of devices to determine whether a destination address of the data packet exists, and the controller acquires a destination port if no destination address of the data packet exists, where the destination port is a port of a switch connected to a destination host, and the destination host is another host different from the source host; and finally, the controller uses the destination port as a destination address to generate a routing table, and sends the routing table to the switch connected to the source host, so that the switch connected to the source host forwards the data packet according to the routing table.

1. A flooding processing method, comprising:
receiving, by a controller, a data packet that is reported by a switch connected to a source host; searching, by the controller, a local media access control (MAC) address table of physical addresses of devices to determine whether a destination address of the data packet exists; acquiring, by the controller, a destination port when no destination address of the data packet exists, wherein the destination port is a port of a switch connected to a destination host, and the destination host is another host different from the source host; using, by the controller, the destination port as a destination address to generate a routing table; and sending the routing table to the switch connected to the source host such that the switch connected to the source host forwards the data packet according to the routing table.
