Problems solved by technology

[0006] (1) Switching cannot be achieved through switching commands;
[0007] (2) It cannot handle the scenario where there is no alarm on the line interface and the service is interrupted, for example: there is a networking scenario where there is a transparent transmission of intermediate node services

Embodiment 1

[0028] see figure 1 As shown, Embodiment 1 of the present invention provides a method for implementing flexible Ethernet protection switching based on reserved overhead fields, including the following steps:

[0029] S1, using the reserved overhead field in the overhead frame specified by the flexible Ethernet FlexE protocol as APS (Automatic Protection Switching, automatic protection switching) overhead, using the APS overhead corresponding to the first 20 frames in a multiframe defined by the FlexE protocol to carry the corresponding time slot APS information;

[0030] S2. If the business supported by the FlexE protocol corresponds to multiple time slots, the sending end inserts the APS overhead into the multiframe corresponding to a certain time slot in the multiple time slots corresponding to the business, and sends it to the receiving end through the APS information transmission channel; the receiving end selects The APS overhead corresponding to the multiframe overhead ...

Embodiment 2

[0032] see figure 2 As shown, Embodiment 2 of the present invention provides a method for implementing flexible Ethernet protection switching based on reserved overhead fields, including the following steps:

[0033] S1. Use the reserved overhead field in the overhead frame specified by the flexible Ethernet FlexE protocol as the automatic protection switching APS overhead, and use the APS overhead corresponding to the first 20 frames in a multiframe defined by the FlexE protocol to carry the APS information of the corresponding time slot;

[0034] S2. If the business supported by the FlexE protocol corresponds to multiple time slots, the sending end inserts the APS overhead into the multiframe corresponding to a certain time slot in the multiple time slots corresponding to the business, and sends it to the receiving end through the APS information transmission channel; the receiving end selects The APS overhead corresponding to the multiframe overhead is used as the APS info...

Embodiment 3

[0040] Embodiment 3 of the present invention provides a system for realizing flexible Ethernet protection switching based on reserved overhead fields. The system includes a sending end, a receiving end, and an APS information transmission channel. The overhead field is used as the automatic protection switching APS overhead, and the APS overhead corresponding to the first 20 frames in a multiframe defined by the FlexE protocol is used to carry the APS information of the corresponding time slot.

[0041] The business supported by the FlexE protocol corresponds to multiple time slots. The sending end inserts the APS overhead into the corresponding multiframe of a certain time slot among the multiple time slots corresponding to the business, and sends it to the receiving end through the APS information transmission channel; the receiving end selects the corresponding multiframe The APS cost of the service is used as the APS information of the service.

Abstract

The invention discloses a method and a system for implementing flexible Ethernet protection switching based on an overhead reserving field, and relates to the field of flexible Ethernet. The method comprises the following steps as follows: the overhead reserving field in an overhead frame specified by a flexible Ethernet FlexE protocol is used as automatic protection switching (APS) overhead, andthe APS overhead corresponding to the first 20 frames in a multiframe defined by the FlexE protocol is used for carrying APS information of a corresponding time slot; if a service supported by the FlexE protocol is corresponding to the plurality of time slots, a sending terminal inserts the APS overhead into the multiframe corresponding to the time slot in the plurality of time slots correspondingto the service, and sends the same to a receiving terminal via an APS information transmission channel; and the receiving terminal selects the APS overhead corresponding to the multiframe overhead toserve as the APS information of the service. According to the method and system provided by the invention, the switching can be achieved via a switching command, with no need to depend on line warning, and the scene that the line interface does not have the warning and thus the service is interrupted can be processed.

Description

technical field [0001] The invention relates to the field of flexible Ethernet, in particular to a method and system for realizing flexible Ethernet protection switching based on reserved overhead fields. Background technique [0002] With the rapid development of the mobile Internet and the emergence of various new applications such as the Internet of Things, the fifth-generation mobile communication (5G) technology has emerged to cope with the explosive growth of mobile data traffic and massive device connections in the future. 5G technology puts forward a series of requirements for the bearer network, such as high bandwidth, low latency, and network slicing. FlexE (Flexible Ethernet, Flexible Ethernet) technology has become a 5G network with its unique characteristics of physical isolation, channel binding, and single-set mapping. An important interface for fronthaul and backhaul networks. However, to realize networking based on FlexE technology, a series of problems suc...
