Problems solved by technology

However, since the application service instance also needs to obtain data from multiple other edge clouds, only migrating the service instance itself can shorten the distance between the user and the service instance, but it may cause the service instance to be far away from the data, which will increase the service response time

Abstract

The invention provides a mobile edge computing service and data collaborative migration method and device, and the method comprises the steps: when a user service needs to migrate due to the position change of a mobile user, according to an edge server where data of a to-be-migrated service is located and a storage state change probability of the edge server where the data of the to-be-migrated service is located, determining a service migration position and a data migration position of the to-be-migrated service when the service response time of the to-be-migrated service is shortest by adopting a particle swarm iterative algorithm; and respectively migrating the to-be-migrated service and the data of the to-be-migrated service to the service migration position and the data migration position. The service response time can be reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile edge computing, in particular to a method and device for cooperative migration of services and data of mobile edge computing. Background technique [0002] As a new network architecture, mobile edge computing sinks computing to the edge of the network close to users or data sources, providing data caching and computing functions. By sinking computing resources, network transmission delay and core network load can be reduced, and user experience quality can be improved. [0003] Service migration is an important issue for mobile edge computing. The coverage of the edge server is limited, and with the movement of users and smart devices, when the moving smart device exceeds the coverage of the edge server, it may cause service interruption and affect service quality. [0004] Current service migration only considers migrating running application service instances from source edge servers to...
