Problems solved by technology

However, when the whole machine is powered off or the openflow channel is interrupted, the transponder (hereinafter referred to as UP) link is abnormal, and the controller (hereinafter referred to as CP) cannot respond in time
[0005] In a hot standby environment, such as figure 1 As shown, if the above situation occurs, the main (master) device, that is, when the (UP) 1 is abnormal, it cannot switch the master and backup in time. This phenomenon is very common in various abnormal situations of the device, and it is not resolved. The problem will make hot standby meaningless in actual use

Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with specific embodiments.

[0048] The embodiment of the present invention provides a method for switching active and standby devices in a hot standby environment, which is applied to a controller, such as figure 2 As shown, the method includes:

[0049] Step 201: Determine that the traffic statistics information sent by the backup device is received;

[0050] Step 202: Determine the current state of the master device;

[0051] Step 203: Determine whether to switch from the master device to the standby device based on the result of the determination and the current state of the master device.

[0052] The embodiment of the present invention can judge whether the master device is abnormal according to the traffic (service data) in the link, so as to switch the master device and the backup device, and can achieve a more reasonable and fast switch; The problem that the flow interruption time caused...

Abstract

The embodiment of the invention provides a method and device for switching main equipment and standby equipment in a hot standby environment. The method comprises the following steps of determining toreceive the flow statistics information sent by the standby equipment; judging the current state of the main equipment; and determining whether to switch from the master device to a standby device based on the determined result and the current state of the master device.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a device for switching master and backup equipment in a hot standby environment. Background technique [0002] With the rapid development of Internet+ and OTT operation models in recent years, network traffic has shown a blowout growth, network scale has become increasingly complex, and operation and maintenance costs have also continued to rise. The Broadband Remote Access Server (BRAS) located at the edge of the MAN is the entrance to realize various user services, and its tightly coupled control and forwarding architectural model can no longer meet the endless new services and traffic. Therefore, it is imminent to build edge virtualization of the metropolitan area network with flexible resources and fast operation. [0003] The Virtual Broadband Remote Access Server (vBRAS) adopts the idea of ​​SDN / NFV, and can realize elastic expansion and flexible ...
