Example Embodiment

[0067] The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0068] In the embodiment of the present invention, the network device needs to perform a power-down alarm in a short period of time (that is, from the loss of the short power input of the network device to the failure of the main device), that is, sending a specific alarm message to the controller or the controller.

[0069] At present, a controller has been introduced in the SDN network to manage and control each network device. The controller and th...

Abstract

The invention discloses a power failure alarm method, a power failure alarm processing method and a device, which is used for ensuring that a power failure alarm message can be sent in time and a power failure alarm can be processed in time. The method comprises the step that network equipment gives a power failure alarm to a controller by adopting a first message generated on the basis of an openflow protocol when determining that the working voltage of the network equipment is lower than a set voltage threshold. Various types of messages based on the openflow protocol are processed by a forwarding chip in the network equipment, and the forwarding chip has the highest processing speed and the highest processing priority in the network equipment, so that the processing speed can meet the time requirement of a last word function, the timely processing of a power failure event is effectively guaranteed, and the service quality of an SDN is guaranteed.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a power-down alarm method, processing method and device. Background technique [0002] In the existing transmission and switching network systems (such as Software Defined Network (SDN)), in order to improve the stability of the network and facilitate the management of the network by the administrator, it is necessary for the network device to provide Dying Gasp) function. [0003] The so-called last words function refers to the ability to make a final alarm notification when a fatal failure occurs in a network device. For example, when the system is powered off, that is, when the input voltage cannot meet the normal operation of the system, the system will automatically send a Dying Gasp message to the network management device or backup device to notify the fault or realize data switching. Among them, usually, The network equipment is equipped with a power storage module...
