Embodiment 1

[0033] like Figure 1 to Figure 3 As shown, a method for controlling MAC drift in a passive optical fiber network in an embodiment of the present invention is introduced, and the method includes the following steps.

[0034] In step S101, the ingress port information of the message is acquired, and the message type of the message is searched in the MAC table.

[0035] When a message comes in from the port of the OLT device, the type corresponding to the message is obtained according to the stored MAC entry in the message learning module.

[0036] like image 3 As shown, in the passive optical network, the OTL device is an intermediate node, one side is connected to the user network, and the other side is connected to the backbone network.

[0037] A first label is added to all the ports on the user side, and after a message enters through the port on the user side, it is learned in the learning module, and at the same time, the message is marked as the first type. Add a sec...

Abstract

The invention discloses a method and application for controlling MAC (Media Access Control) drift in a passive optical fiber network, and the method comprises the following steps: obtaining the ingress port information of a message, and searching the message type of the message in an MAC table; matching an access control list corresponding to the ingress port information based on the message type, wherein the access control list comprises a drift control table item; and controlling MAC (Media Access Control) drift according to a matching result with the drift control table item in the access control list. According to the method, the MAC drift of the message can be controlled according to the access control list, the priority control requirement of the MAC drift of the uplink port and the downlink port in a passive optical fiber network scene can be met, the hierarchical management of the MAC drift is realized, the normal operation of the network is ensured, and the phenomenon of network looping is avoided.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and application for controlling MAC drift in a passive optical fiber network. Background technique [0002] Passive optical network technology is the latest generation of broadband passive optical fiber integrated access standard based on the ITU-TG.984.x standard. A technology accepted and applied. In the data encapsulation of the passive optical fiber network, the ONU receives the upstream data from the user network side, the ONU encapsulates the upstream data into a GEM frame, and sends it to the OLT, and the OLT decapsulates the GEM frame into ETH data, and sends Go out, go down and come in. [0003] Usually, the OLT line card in the passive optical network system will support 16 passive optical ports, and each passive optical port has a splitting ratio of 128. If there is packet MAC drift in the entire system due to some reasons, it will cause A data storm occurs in the...
