Abstract

The invention discloses a broadcast message processing method and a device and relates to the field of message transmission. The method comprises steps of: acquiring broadcast messages in one direction, analyzing the acquired broadcast messages to obtain message feature information of the broadcast messages, dividing the acquired broadcast messages into different types according to the message feature information, and carrying out rate inhibition on each broadcast message type. Through the above fine-grained message inhibition scheme, on one hand, the broadcast messages in the uplink or downlink direction can be effectively inhabited, and on the other hand, normal broadcast messages needed by various services can be ensured to be forwarded as much as possible while the broadcast storm is effectively inhabited.

Description

technical field

[0001] The invention relates to the field of message transmission, in particular to a broadcast message processing method and equipment. Background technique

[0002] During the large-scale construction of broadband access networks based on Passive Optical Network (PON), once a broadcast storm occurs in the PON system, a large amount of network bandwidth will be occupied, and the network performance of the PON will decrease. , causing normal business operations to fail.

[0003] Currently, a switch chip of an optical line terminal (Optical Line Terminal, OLT for short) device of a passive optical network supports a broadcast suppression function. The optical line terminal has set the upper limit value of the broadcast packets in a certain direction (that is, the uplink direction or the downlink direction) that it can forward within a unit time. If the packet exceeds the set upper limit, any broadcast packets received after the upper limit will be discarded....
