Edge Computing Server Application Caching for Latency Reduction

The patent applies preliminary action by pre-loading and caching application image files in the MEC platform before they are actually requested by terminal devices. When an application is first accessed, the system downloads and stores its image file in the MEC platform's cache, so that subsequent accesses can be served immediately without waiting for image file mounting or execution preparation. This resolves the contradiction by performing the time-consuming image file preparation in advance.

The patent applies local quality by implementing a caching mechanism that stores frequently accessed application image files locally in the MEC platform. Instead of running all requested services from the core cloud server, the system identifies which applications are frequently requested by terminal devices in the local area and caches their image files locally. This allows the MEC to efficiently serve local requests using cached images while maintaining the ability to handle diverse service requests, thus providing good service coverage without overwhelming MEC resources.

The patent applies the intermediary principle by introducing the MEC platform as a mediator between the core cloud server and terminal devices. The MEC platform caches application image files and serves them to local terminal devices, acting as an intermediate storage and distribution layer. This reduces the distance and network latency between the core cloud server and terminal devices while maintaining service completeness, as the MEC platform retrieves images from the core cloud server when needed and serves them locally to end users.
