Embodiment approach

[0046] The embodiment of the present invention provides a method for avoiding communication interruption between devices due to device response delay when the EAPs ring is restored. The implementation plan is as follows:

[0047] (1) Deploy EAPs on the Ethernet ring network.

[0048] (2) When the link is restored, the Master caches the first up message received.

[0049] (3) The Master sends a flush message to other devices on the EAPs ring until the up message is received on both the master port and the slave port.

[0050] (4) During the buffering of the up message, if the down message is received again, the previously cached up message is directly canceled.

[0051] After the implementation of the above scheme, when deploying the EAPs ring, there is no need to worry about communication error interruption caused by device response delay.

[0052] The above steps are described in detail below:

[0053] According to the present invention, after the switch device finds that...

Abstract

The invention provides an Ethernet ring net link recovery detection method and a main Ethernet ring net switch; the method includes that the main Ethernet ring net switch blocks the slave port when the main Ethernet ring net switch receives the link recovery messages from a master port and the slave port; the main Ethernet ring net switch sends the instruction messages of releasing the temporally-blocked ports to the switches on both ends of the link needs to be recovered through the master and the slave ports. The Ethernet ring net link recovery detection method and the main Ethernet ring net switch improve the haleness of the EAPs ring and avoid the long time interruption problem caused by the device response delay in the occasions which have high communication quality and need the EAPs ring to be deployed so that the EAPs ring is enabled to be applicable to more practical environments.

Description

technical field [0001] The invention relates to the Ethernet technology, in particular to a method for improving the robustness of the Ethernet ring network, in particular to a method for detecting link recovery of the Ethernet ring network and a master switch of the Ethernet ring network. Background technique [0002] With the rapid development of Ethernet technology and the continuous improvement of applications, it has become an irresistible trend to use cost-effective Ethernet technology to build large-scale enterprise networks and metropolitan area networks. In such large-scale and multi-service network environments, most of them deploy ring topologies, such as figure 1 As shown in , the feature of the ring topology is that each device uses two ports to interconnect with adjacent devices to form a closed link. [0003] If Ethernet switches are used to build this ring topology, we call it an Ethernet ring. In an Ethernet ring network, the two most critical functions ar...
