Abstract

The invention discloses a method and a system for avoiding outage of a communication device; the communication device comprises one or more single-boards; the method comprises the following steps: operating an embedded virtualization platform on the single-boards; establishing N virtual machines according to to-be-operated tasks of the single-boards on the embedded virtualization platform, wherein N is greater than 1; one virtual machine is established as a master virtual machine, and the other N-1 virtual machines are established as standby virtual machines; operating tasks on the master virtual machine, and synchronizing task state and operation data in real time between the master virtual machine and the standby virtual machines; and switching tasks to the standby virtual machines to operate continuously when detecting the master virtual machine operates abnormally. The method and the system provided by the invention can form multi-backup for software systems in the device under a condition that volume and hardware cost of the communication device are not increased, and ensure tasks are switched to standby software system to operate continuously when software of the communication device goes wrong so as to ensure operation of the communication device is not interrupted.

Description

technical field [0001] The invention relates to the embedded field and the communication field, in particular to a method and a system for avoiding interruption of communication equipment operation. Background technique [0002] Today's communication devices are generally embedded devices. It is found through statistics that the abnormal operation of communication devices is often due to software failures (operating system or application software failures). When a single board in the communication device works in stand-alone mode, once a software failure occurs, the communication is usually restored by restarting the board or the entire communication device. Since the restart operation takes a long time (minutes), it causes Long-term communication interruption, in some occasions that require high operational reliability, this long-term communication interruption cannot be allowed. However, if the single board in the communication device is configured as dual-system hot stan...
