Abstract
In one aspect, the invention provides a layer 2 network device that implements a fast retransmission method that causes the layer 2 network device to transmit proposal messages more frequently than defined in the RSTP standard. By transmitting proposal messages (e.g., proposal RST BPDUs) more frequently, the network device can significantly reduce the duration of a network traffic outage caused by a lost proposal message or a lost agreement message.
