Embodiment Construction

[0041] In order to improve the task processing requirements of the power distribution communication network, the invention discloses a task migration method of the power distribution communication network based on SDN-MEC. This method utilizes the characteristics of SDN (Software-Defined Networks) global control and MEC (Mobile Edge Computing) network edge services to build a flexible and efficient power distribution communication network, and uses a reasonable method to distribute Task service node resources, migrate tasks with different requirements to corresponding service nodes for processing, and reduce the data processing delay of power distribution and consumption terminals. That is to use the characteristics of low service processing delay of mobile edge computing and centralized management and control of software-defined network technology to build an SDN-MEC-based power distribution communication network architecture, analyze the computing task model, and design the t...

Abstract

The invention discloses a power distribution and utilization communication network task migration method based on SDN-MEC, and belongs to the field of power information communication. The method comprises the following steps: constructing a power distribution and utilization communication network based on an SDN-MEC architecture, and deploying MEC service nodes to meet calculation tasks with low time delay and high bandwidth requirements; abstracting a service and service node model according to the power distribution and utilization communication network architecture; comprehensively considering task requirements, execution cost and service node resource states, and designing a calculation task migration method; and finally, realizing a specific migration process by adopting an improved ant colony algorithm.

Description

technical field [0001] The invention belongs to the field of electric power information communication, and in particular relates to a calculation task migration method of a power distribution communication network. Background technique [0002] With the continuous construction and development of the smart grid, the types of power information communication services are diversified, the data information is massive, the communication requires high reliability, security and real-time performance, and the QoS requirements of various services are different. Traditional power distribution and consumption The communication network architecture is facing huge challenges. The centralized master station data processing center has heavy communication tasks and low efficiency. If all terminal data is uploaded to the remote server center for processing, serious delay and power consumption problems will occur. [0003] Existing research mainly focuses on improving the utilization rate of b...
