Embodiment 1
[0062] see figure 1 , figure 1 It is a schematic flowchart of a method for automatically enabling a forward error correction code function provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0063] Step S10: Determine the sending rate of the test message according to the line bandwidth;
[0064] Specifically, the line bandwidth refers to the bandwidth allocated by the optical line terminal to the optical network terminal, wherein the line bandwidth can be allocated dynamically to better realize the effective utilization of line resources. The sending rate of the test message may be determined according to the bandwidth dynamically allocated to the optical network terminal by the optical line terminal. It can be understood that the sending rate of the test message should not exceed the line bandwidth. For example: you can set the sending rate of the test message as 90% of the line bandwidth, and send the test message at the...
Embodiment 2
[0079] see figure 2 , figure 2 It is a schematic diagram of an application scenario for automatically enabling the forward error correction code function provided by the embodiment of the present invention, as shown in figure 2 As shown, the optical line terminal sends the test message to the optical network terminal, and the optical network terminal sends the test message back.
[0080]Wherein, the method for automatically enabling the forward error correction code function includes: determining the transmission rate of the test message according to the line bandwidth; according to the transmission rate, sending the test message to the optical network terminal, and notifying the optical network The terminal sends back the test message; judges the line quality according to the test message returned by the optical network terminal; determines whether to enable the forward error correction code function according to the line quality.
[0081] Specifically, after the optical...
