The application discloses an implementation method and device of an asymmetric cascading protection model, equipment and a storage medium, wherein the method determines the model type of the cascading protection model according to the number of entry nodes and the number of exit nodes of the protection group of the cascading protection model; according to the model type, the automatic protection switching (APS) information of the secondary node is attached in the protocol bridging field; according to the type of the cascading protection model and the APS information, the APS processing state machine under the asymmetric cascading protection model is generated; the seamless compatible operation of the traditional tangent model and the telecom i2 tangent model can be realized, the reliable transmission of the APS byte under the asymmetric configuration is ensured, the protocol handshake and path switching of the two-end equipment are successfully completed, the operation and maintenance complexity is reduced, the false switching is effectively avoided, the real-time response capability and the system robustness of the network protection are improved, a standardized solution for the multi-vendor equipment interoperation is provided, and the speed and the efficiency of the implementation of the asymmetric cascading protection model are improved.

The application discloses an automatic protection switching method and device in a flexible Ethernet, and a storage medium, and the method comprises the following steps: obtaining target data transmitted by a first chip logical forwarding module on a first device; in the case that a first automatic protection switching module on the first device is in a first transmission mode, copying the obtained target data twice to obtain two copies of the target data; and transmitting the two copies of the target data to a second device through a target protection channel and a target working channel in a flexible Ethernet (FlexE). By adopting the technical scheme, the technical problem that APS technology cannot be applied to a flexible Ethernet client is solved.

The application relates to a method and system for realizing a service label adaptation of a ring service, and relates to the field of automatic protection switching of a PTN network, and comprises the following steps: after a service is bound to a ring network, the out label of a service channel is set as the in label of an upper ring node, and a ring label of the ring in which the upper ring node is located is added to the upper ring node; the ring label is forwarded through a ring channel in a middle node of the ring, and the ring label is popped out at a lower ring node. The application solves the problem that services with inconsistent service labels of upper ring nodes and lower ring nodes cannot be bound to a ring, expands the application scene of ring network protection, and greatly improves the engineering usability of the ring network protection function.
