Embodiment Construction

[0087] In the technical solution of each embodiment of the present invention, in order to ensure the business continuity before and after the migration of the application instance, the snapshot method is used to migrate the application instance, that is, take a snapshot of the source application instance, so that when the application instance needs to be migrated, the Use the snapshot on the destination mobile edge host to restore the application instance to the state before migration.

Abstract

The invention discloses a method and device for migrating an application instance, comprising: taking a snapshot of a source application instance by a source mobile edge host; and synchronizing the snapshot between the source mobile edge host and a destination mobile edge host, so that the destination mobile edge host can perform snapshot synchronization. The snapshot synchronized to the destination mobile edge host is resumed; wherein, the snapshot is the running space of the source application instance at the time of shooting, and the running space includes the running process and state information. The destination mobile edge host receives the snapshot of the source application instance sent by the source mobile edge host; restores the snapshot to the destination application instance on the destination mobile edge host; runs the destination application instance on the destination mobile edge host; Wherein, when running the target application instance, the running process and state information of the snapshot are performed.

Description

technical field [0001] The invention relates to instance migration technology in the communication field, in particular to a method and equipment for application instance migration. Background technique [0002] Mobile Edge Computing (MEC, Mobile Edge Computing) reduces access time by deploying applications (such as video streaming edge, local cache content distribution network (CDN, Content Delivery Network), etc.) delay, save bandwidth, and improve throughput. The European Telecommunications Standards Institute (ETSI, European Telecommunications Standards Institute) MEC working group defines the architecture of mobile edge computing, such as figure 1 shown. [0003] In this architecture, the mobile edge host (Mobile Edge Host) includes a virtualization infrastructure (Virtualization infrastructure), on which there is a data forwarding function (Data plane). A mobile edge platform (Mobile edge platform) and several mobile edge applications (ME app, Mobile Edge applicatio...
