Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0035] see figure 1 As shown, the embodiment of the present invention provides a flexible Ethernet 1:1 protection switching implementation method, and the flexible Ethernet is composed of an end node and an intermediate site, and is characterized in that:

[0036] Set up a working path and a protection path between the two end nodes; set the nodes at both ends to use the working path to send services by default. When the service is not switched to the protection path, the protection path sends different services from the working path. Use the working path to receive services; set the return type and waiting recovery time of the end node, the return type includes returning or not returning, and the waiting recovery time is the waiting time before switching to receiving services from the working path; the waiting recovery time can be set to 0, t...

Abstract

The invention discloses a flexible ethernet 1:1 protection switching implementation method, and relates to the technical field of flexible ethernet networking protection. A work path and a protection path are arranged between two end nodes; the two end nodes are set to use the work path to transmit services by default, the protection path transmits services different from the services in the work path when the services are not switched to the protection path, and the two end nodes use the work path to receive the services by default; when the end nodes detect port fault alarm or AIS alarm on the work path, the services are switched to the protection path; and when cancellation of port fault alarm and / or AIS alarm on the work path is detected: the services are maintained to be received from the protection path or the work path is switched on to receive the services after water-to-restore time. Meanwhile, the end nodes transmit an APS command to the opposite end node, and the opposite end node performs the synchronous protection switching action according to the APS command so that rapid automatic protection switching in the flexible ethernet can be implemented.

Description

technical field [0001] The invention relates to the technical field of flexible Ethernet networking protection, in particular to a method for implementing flexible Ethernet 1:1 protection switching. Background technique [0002] The Flexible Ethernet (FlexE) protocol provides a general mechanism that supports various Ethernet MAC layer rates for transmission using the existing Ethernet PHY chip, and realizes the decoupling of the MAC layer and the PHY layer during the service transmission process, eliminating the need for optical The module's constraints on the transmission of large-bandwidth services. [0003] 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 n...
