BROADCAST STORM PREVENTION METHOD AND APPARATUS

摘要

Disclosed in the present invention is a broadcast storm prevention method, comprising: a network device receives a broadcast message; the network device determines whether the broadcast message is repeatedly received; if the broadcast message is repeatedly received, the network device determines whether a reception time difference of the broadcast message, compared with the broadcast message received last time, is less than a threshold value, and determines whether the number of times of receiving the broadcast message is greater than the threshold value; and if the reception time difference of the broadcast message, compared with the broadcast message received last time, is less than the threshold value, and the number of times of receiving the broadcast message is greater than the threshold value, the network device discards the broadcast message. The broadcast storm is prevented in the case that a networking structure between routes and a broadcast packet delivered between the routes are not changed.
