Abstract
As an education mode and teaching method of modern education, digital teaching in colleges and universities plays a role of bridge and hub in the development of modern education. Digital teaching has become one of the important driving forces for the development of digital and informatization of education in colleges and universities. This paper combines edge computing and digital technology to study the mobile information system used in the digital teaching of college English, namely, the digital teaching platform. In the technical part, this article clarifies the concept of mobile information system and introduces edge computing, cloud computing, digital system structure, and other technologies in detail; the system design and implementation part introduces the system architecture, function design, and how to realize the system function. In the system test section, black box and white box tests were performed on the system. The test results show that all functions of the system can be used normally and have certain feasibility. The mobile information system reduces the average content transmission delay (ADL) by approximately 14%-22% and 21%-31%, respectively, which greatly improves the efficiency of digital teaching of English in colleges and universities.
Highlights
IntroductionIf we can combine the edge computing of mobile information system and the digital teaching of college English, university education can be made more scientific and digital
The whole process is divided into three steps: in the first step, the SDN controller obtains the corresponding diversion strategy from the server; in the second step, in compliance with the diversion strategy and network flow information, the SDN controller formulates the corresponding diversion rule table and sends it to the diversion gateway; in the third step, the shunt gateway performs final shunt according to the shunt forwarding rule table [13]
The four functional modules of identity authentication, information inquiry notification sending, and opinion feedback will be analyzed and designed in detail below according to the characteristics of the digital teaching platform
Summary
If we can combine the edge computing of mobile information system and the digital teaching of college English, university education can be made more scientific and digital. Aiming at the new architecture after dating edge computing, Zhang starts from task migration in multiuser scenarios and the expansion of edge server resource management, focusing on task offloading in edge computing [8] They are not going to build a mobile information platform for digital education. The innovation of this paper is to combine mobile information systems with cloud computing and edge computing to apply it to the research of digitization of English teaching in colleges and universities and to promote the realization of digitized teaching and digital campus in colleges and universities. The scope of teaching management continues to expand, the amount of information that needs to be processed increases sharply, and the sources and forms of information are increasingly diversified, which puts forward higher requirements for the rigor, accuracy, and timeliness of teaching management
