Abstract

The invention discloses a method for pre-allocating edge domain resources in an edge computing scenario, which includes the following steps: predicting the arrival rate and measuring the forwarding delay, and determining the service pre-cache value in the first-level edge domain according to the arrival rate and the weight of the service type, and determine the allocation ratio of each service according to the first delay; in the second-level edge domain, determine the type of service pre-caching according to the second delay, and obtain the initial cache solution through the interior point method; by randomly selecting the service cache type A new resource caching scheme is obtained by means of a new resource caching scheme, and the scheme with a smaller average delay is selected from the initial caching scheme and the new resource caching scheme as the final pre-allocation scheme, and then the pre-allocation is completed. The present invention uses statistical data to estimate the needs of users in the next period, and pre-allocates service types and quantities to edge servers according to the estimated data, so that the present invention can perform more efficient resource allocation and improve resource utilization rate and reduce application latency.

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...
