Abstract

The invention discloses a pre-distributing method for edge domain resources in an edge computing scene, the method comprises the following steps of: predicting an arrival rate and measuring a forwarding delay, determining the type of a service pre-cache according to the arrival rate and the weight of a service in a first-level edge domain, and determining the distribution proportion of each service according to a first delay; determining the type of the service pre-cache according to the second time delay in the second-level edge domain, and obtaining an initial cache scheme through an interior point method; obtaining a new resource caching scheme by randomly selecting a service caching type, selecting a scheme with relatively small average time delay from an initial caching scheme and thenew resource caching scheme to serve as a final pre-distribution scheme, and thus completing pre-distribution. According to the method, the demand of the user in the next period is estimated by utilizing the statistical data, and the service type and quantity of the edge servers are pre-allocated according to the estimated data, so that more efficient resource allocation can be carried out, the resource utilization rate is improved, and the application delay is shortened.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for pre-allocating edge domain resources in an edge computing scenario. Background technique [0002] Mobile edge computing (Multi-access edge computing, MEC) is an emerging ecosystem that aims to integrate telecommunications and IT services and provide a cloud computing platform at the edge of the radio access network. MEC provides storage and computing resources at the edge, reduces the delay of mobile terminal users, and more effectively utilizes bandwidth resources in mobile networks. MEC provides cloud computing and storage resources at the edge of the mobile network, creating significant advantages such as ultra-low latency, dense computing power, and reducing network congestion, which is essential for emerging applications such as IoT, video streaming analysis, augmented reality, and connected cars is compulsory. [0003] Users' requirements for computing capab...
