Container-based mobile code offloading support system in cloud environment and offloading method thereof

A container-based mobile code offloading support system in a cloud environment, characterized in that the system comprises a front-end processing layer, a runtime layer and a back-end resource layer, wherein:

• the front-end processing layer is located at a cloud portal and used for responding to an arrived offloading request in the first place, and comprises a request distribution module, a code caching module and a monitoring and scheduling module, wherein:
• the request distribution module is used to capture a user offloading request and distribute the request to a particular container runtime environment for execution;
• the code caching module is used to search for an offloading code to be executed in cached data according to an application source of the request, and directly take the part of the code out of the cached data without making a request to a terminal if the offloading code is present;
• the monitoring and scheduling module is used to monitor usage of a container and reallocate improper resource configurations to update status data of the container;
• the runtime layer is located at a main body of a cloud platform and used to provide an execution environment for a mobile code, and comprises a runtime module, wherein:
• the runtime module is consisted of a plurality of mobile cloud containers causing a customized operating system to be run in a container environment, so as to simulate an execution environment consistent with that of a terminal for an offloaded mobile application;
• the back-end resource layer is located at the lowermost layer of a cloud server and used to support a platform, and comprises a resource sharing module and an extended kernel module, wherein:
• the resource sharing module extracts and provides the common part in the plurality of mobile cloud containers of the runtime layer as shared resource;
• the extended kernel module performs a dynamic extension to a kernel of a host operating system of an original cloud platform, adds a kernel characteristic of a mobile operating system, and realizes the sharing of the kernel between the host operating system and the mobile cloud container, providing a precondition for the running of the mobile operating system in the container.
