Embodiment Construction

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] In the embodiment of the present invention, an intermediate state is added to the original master station and slave station. The device in the intermediate state in the ring network can send the first detection message to other devices in the ring network through the ring ports on both sides. , And receive the first detection message sent by the other device for master station election; during the master station election process, if the device receives a negative response message sent by the other device, it will change the current status from the middle The status is set as the slave ...

Abstract

The invention is applicable to the technical field of communication, and provides a failure recovery method and device of a ring network. The failure recovery method is applied in devices forming the ring network. The method comprises following steps of sending first detection messages to other devices in the ring network by ring ports at two sides when a local device is in an intermediate state; receiving the first detection messages sent by the other devices for master station election; setting the current state from the intermediate state to a slave station if the local device receives negative response messages sent by the other devices in the master station election process; setting the current state from the intermediate state to a master station if the local device does not receive the negative response messages sent by the other devices, thus managing the ring network. Through adoption of the method and the device, when a failure appears in the ring network, the new master station can be elected again, the network failure is recovered by establishing a new network topology, and the problem that in the prior art, the network failure cannot be processed and recovered when the failure appears in the master station.

Description

Technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a method and device for restoring a ring network failure. Background technique [0002] The existing ring network composed of Ethernet switches mainly adopts topology-based network failure recovery protocol, and improves network availability through network redundancy. When a single failure occurs in the switch of the ring network or the link inside the switch, the network function can be restored within a certain period of time. However, the existing network fault detection usually uses a master station to send fault detection messages to detect and handle the failure of the slave station; when the master station itself fails, it is often unable to handle and realize the recovery of the network failure. Summary of the invention [0003] In view of this, the embodiments of the present invention provide a method and device for fault recovery of a ring network to solv...
