Problems solved by technology

PTN (Packet Transport Network, Packet Transport Network) network provides the ring network protection function, ring network protection from the aspects of network reliability and security, convenient and efficient configuration and maintenance, resource utilization, applicable network topology and network expansion level capabilities. It is better than linear protection, but the current FlexE interface protocol of the SPN (Slicing Packet Network, slicing packet network) network does not define the ring network APS (Automatic Protection Switching, automatic protection switching) method of the client, nor does it define the interaction process of the ring network APS and switching process

Abstract

The invention provides a flexible Ethernet looped network protection method. The first direction of each node in a flexible Ethernet looped network corresponds to the second direction of the adjacent node on the corresponding side, and each node is provided with four time slot channels with the same number of time slots; the four time slot channels comprise a working time slot channel and a protection time slot channel which are located in a first direction and belong to the same flexible Ethernet ring network group, and a working time slot channel and a protection time slot channel which are located in a second direction and belong to the same flexible Ethernet ring network group; and the working time slot channel and the protection time slot channel can respectively bear a first service flow and a second service flow which are opposite in service flow direction. The method comprises the following steps: if detecting that a link fault occurs between a current node and an adjacent node in a first direction, converting a normal state into a ring bridge switching state in the first direction, so that a first service flow and a second service flow copy one copy and are switched from a working time slot channel to a protection time slot channel.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a flexible Ethernet ring network protection method, device, computer equipment and computer readable medium. Background technique [0002] The Flexible Ethernet (Flexible Ethernet, FlexE) protocol provides a service that supports various Ethernet MAC (Media Access Control, media access control layer) layer rates. It uses the existing Ethernet PHY (PortPhysical Layer, port physical layer) chip to perform The general mechanism of transmission realizes the decoupling of the MAC layer and the PHY layer in the service transmission process, and releases the constraints of optical modules on large-bandwidth service transmission. [0003] With the rapid development of the mobile Internet and the emergence of various new applications such as the Internet of Things, in order to cope with the explosive growth of mobile data traffic and massive device connections in the fu...
