Embodiment Construction

[0047] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0048] The present invention operates in heterogeneous edge server clusters sensitive to computing migration costs, such as figure 1 As shown, the edge server refers to an edge device that is closer to the terminal and has certain computing and storage capabilities. It can process the tasks offloaded by the terminal in a timely manner and feedback the results in a timely manner within a relatively low delay. The edge computing environment refers to a three-tier architecture composed of intelligent terminals, edge servers, and cloud computing centers. Heterogeneous edge refers to the edge computing environment in which the computing and storage capabilities of edge servers are inconsistent and their performance is significantly different. In a heterogeneous edge environment, due to the limited computing power of a single edge server and the dyna...

Abstract

The invention discloses an edge collaborative storage method for the real-time data processing application in a heterogeneous edge environment. The method comprises the following steps of firstly, determining a neighbor server set; then, calculating the storage benefit of the model data corresponding to each application relative to the cloud for all edge servers, generating an initial storage benefit matrix, wherein the storage benefit is mainly reflected in time delay reduction; searching a storage candidate scheme with the maximum storage benefit from the storage benefit matrix; if the corresponding edge server has enough space to accommodate the model data, storing and updating the residual storage space of the edge server and the storage benefits of other model data influenced by the storage operation; otherwise, setting the benefit value to be infinitely small, and not considering the storage candidate scheme any more; and repeating the two steps until the storage spaces of all the edge servers are not enough to accommodate new model data.

Description

technical field [0001] The invention relates to the field of edge computing platform and edge server management, in particular to an edge collaborative storage method for real-time data processing applications under a heterogeneous edge computing environment. Background technique [0002] With the further development of technologies such as the mobile Internet and the Internet of Things, smart terminals such as mobile phones and wearable devices are rapidly becoming popular and becoming an indispensable part of daily life. At the same time, real-time data processing applications running on smart terminals emerge in an endless stream. For example, smart voice assistants can understand voice commands issued by users and understand user habits; smart camera applications can intelligently identify shooting scenes and optimize camera parameters; Operations such as transformation can be considered as a real-time data processing task. These tasks have three characteristics: compu...
