Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] image 3 A flow chart showing a backup switching method between switch devices at the same level according to an embodiment of the present invention includes the following steps:

[0032] Step S10, the node in the Ethernet ring network detects the link status of the ports of the two peer switches connected to it;

[0033] Step S20, if both ports are normal, then block the slave port of the two ports, release the master port of the two ports, and set the state of the Ethernet ring network to be connected, Figure 5 A schematic diagram showing no faults in the uplink according to an embodiment of the present invention;

[0034] Step S30, the node detects the link state of the master port; and

[0035] Step S40, if it is detected that the master port fails, then release the slave port, block the master port, and set the state ...

Abstract

The invention provides a spare switching method and devices among the same-level switch equipment, the method comprises the following steps: detecting link state of ports of two same-level switches which are connected with a node of an Ether looped network with the node in the ether looped network, if two ports are all normal, and blocking auxiliary ports in the two ports, opening main ports of the two ports, and setting the state of the Ether looped network to be a connecting line, detecting link state of the main ports with node, and if the main ports are checked out to cause faults, and then opening the auxiliary ports, blocking the main ports, and setting the state of the Ether looped network to be disconnected. The invention shortens spare switching delay among the same-level switches.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for backup switching between switch devices at the same level. Background technique [0002] With the rapid development of network scale and the continuous improvement of network quality requirements, network applications have higher and higher requirements for reliability, and various link protection mechanisms have emerged, among which dual uplink is one of the commonly used networking modes at present. Under the action of the IP / MPLS routing mechanism in the L3 network, dual uplink traffic load sharing and protection switching are not particularly difficult issues. [0003] Currently, in the Layer 2 network and where the Layer 2 network is connected to the Layer 3 network, the traffic load sharing and protection switching of the dual-homing network, such as large-capacity BRAS / SR equipment, many access users, once the port and downlink The effectivene...
