Example Embodiment

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

[0048] Embodiments of the present invention provide a method for switching between 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 standby device is received;

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

[0051] Step 203: Based on the determined result and the current state of the master device, determine whether to switch from the master device to the standby device.

[0052] The embodiment of the present invention can judge whether the main device is abnormal according to the traffic (service data) in the link, so as to switch the main device and the standby device, which can achieve more reasonable and fast switching; The problem that the flow interruption time is too long du...

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 ...
