Problems solved by technology

[0003] In the existing self-healing rings of industrial switches, either there is no concept and definition of dual-homing rings; or the dual-homing rings are built for the same ring instead of nodes; this results in either a lack of protection for core nodes, or There are many restrictions on setting the core node, which is not flexible and convenient

Embodiment 1

[0045] The embodiment of the present invention provides a dual-homing ring-based switch redundancy backup method, which is suitable for industrial switches, see figure 1 , The method can include:

[0046] Step S11, the host switch initiates dual-homing detection to the node switches in the preset dual-homing ring network. The dual-homing ring network includes the host switch and multiple node switches, and the multiple node switches are connected to each other to form multiple connected or In a topological networking structure composed of tangent single rings, the two ring network ports of the host switch are respectively connected to any two different node switches in the topological networking structure.

[0047] In this embodiment, the switch redundancy backup method is implemented based on a reconstructed dual-homing ring network, which mainly includes a host switch and multiple node switches, and multiple node switches are connected to each other to form multiple single rings a...

Embodiment 2

[0066] The embodiment of the present invention provides a dual-homing ring system, which implements the switch redundancy backup method described in the first embodiment, see figure 2 The dual-homing ring system may include: a host switch 1 and a plurality of node switches 2. The multiple node switches 2 are connected to each other to form a topology network structure composed of multiple connected or tangent single rings, and two of the host switch 1 The ring network ports are respectively connected with any two different node switches 2 in the topology network structure.

[0067] Specifically, see image 3 , The host switch 1 may include:

[0068] The first sending module 11 is configured to send a dual-homing data packet for dual-homing detection to a connected node switch through a ring network port. The dual-homing data packet includes: MAC address information of the host switch and dual-homing data information.

[0069] The first receiving module 12 is configured to receive a ...

Abstract

The invention discloses a switch redundancy backup method based on a double-return ring and a double-return ring system. The method comprises the following steps: initiating the double-return detection to a node switch in a preset double-return ring network through a host switch; when each node switch in the double-return ring network passes the double-return detection, regarding that the double-return ring network works in normal; and performing the redundancy backup protection on a data link connected with the host switch through the double-return ring network. In the double-return ring network provided by the invention, multiple node switches are mutually connected to form a topologic network structure formed by multiple connected or tangent single rings, two ring network ports of the host switch are respectively connected with any two different node switches in the topologic network structure. The double-return ring network is defined based on the switch, two ring ports of the host switch can access into any two different nodes in any tangent rings or crossed rings, the connecting way is flexible and convenient, the limitation on the host switch is less, and the redundancy backup protection reliability is high.

Description

Technical field [0001] The invention relates to the technical field of industrial switch redundancy backup, in particular to a switch redundancy backup method based on a dual-homing ring and a dual-homing ring system. Background technique [0002] In order to maintain the stability of the network, in a network environment composed of multiple switches, some backup connections are usually used to improve the robustness and stability of the network. The backup connections here are also called backup links or redundant links. [0003] In the existing industrial switch self-healing ring, either there is no concept and definition of dual-homing ring; or dual-homing ring is built for the same ring, not for nodes; this causes either the core node to lack protection, or There are many restrictions on setting the core node, which is inflexible and convenient. Summary of the invention [0004] In order to solve the problems of the prior art, the embodiments of the present invention provide a...
