Problems solved by technology

[0018] The second scheme is also tree-based switching. When the service data packet is switched, it cannot avoid the flooding of the unicast data stream forwarded according to the known data path forwarding table before the switch in the switched area.

Example Embodiment

[0071] The core idea of ​​the present invention is: when a fault occurs in the protection switching network, only the services between the protection switching points affected by the fault are switched, and the services between the protection switching points not affected by the fault are not switched.

[0072] Specifically, configure connection-based protection switching network information to determine the working port and protection port of each protection switching point; each protection switching point periodically broadcasts through its own working port and protection port during the preset detection time Fault detection message, detect the respective near-end working / protection path, remote working / protection path; within the preset detection time, if the working / protection port of a certain protection switching point does not receive a fault detection message, the protection switching point determines The path where the fault detection message is located fails, and sends a...

Abstract

In the invention, when a protection switch network goes wrong, only the service between the protection switch points influenced by the failure will be switched, and the service between the protection switch points not influenced by the failure will not be switched. The invention lowers the influence caused by a failure to MP2MP service.

Description

technical field [0001] The invention relates to network protection technology, in particular to a protection switching method based on a connectionless network. Background technique [0002] A protection switching network based on a connectionless network is composed of an Ethernet switch at the core, also called a core device, and an Ethernet switch or router at an edge, also called an edge device or an edge node. Wherein, the edge device is responsible for performing service switching operation when a fault occurs inside the protection switching network, and the edge device is directly connected to the external device of the protection switching network. In the protection switching network, data is forwarded in a connectionless manner, for example, in an Ethernet, data packets are forwarded through a data path forwarding table established based on a spanning tree environment. This network, which forwards data packets in a connectionless manner, consists of interconnected ...
