【摘要】 新冠疫情大大加速了在线教学方式的应用,而大规模应用和教学全流程覆盖对教学系统提出了新要求。如何检验在线教学体系各子系统支撑大规模应用的能力,以及时弥补体系的薄弱环节,是众多高校面临的共同挑战。为应对这一挑战,文章首先分析了全链路压测的现状和高校进行信息系统全链路压测的特征,在此基础上设计了面向高校的全链路压测模式。随后,文章在浙江大学进行了全链路压测的实践应用,发现全链路压测能够及时发现在线教学体系中各子系统存在的薄弱环节,为改善系统性能、有效保障系统稳定性、提高访问能力、更好地保障在线教学质量提供了科学依据。最后,文章指明了全链路压测的未来改进思路,以期为高校在线教学支撑体系、混合教学支撑体系和未来智慧教学支撑体系的性能测试提供借鉴。更多还原

【Abstract】 The Covid-19 epidemic has greatly accelerated the application of online teaching methods, and the large-scale application and teaching full-process coverage have put forward new demands on the system. How to test the ability of various subsystems of the online teaching system to support large-scale application, and to make up the weak link of the system timely is a common challenge faced by many universities. In order to cope with this challenge, this paper firstly analyzed the current situation of the full-link load pressure test and the characteristics of full-link load pressure of information system in universities. Based on this, this paper designed a full-link load pressure test model for online teaching support system in universities. Subsequently, a practical application were carried out in Zhejiang University. It was found that the model can timely find the weak links in each subsystem of online teaching system, and provide scientific basis for improving the system performance, effectively guaranteeing the system stability, promoting the access capability, and better guaranteeing the online teaching quality. Finally, the paper pointed out the idea for future improvement of full-link load pressure testing, expecting to provide reference for universities’ performance test of online teaching support system, blend teaching support system, and future intelligent teaching support system.更多还原
