摘要
为满足新工科建设和物联网课程教学的需求,结合存储和纠删码领域的前沿知识,提出了一套基于喷泉码的分布式云存储教学系统,将物联网中传输层协议与喷泉码特性灵活结合。以“物联网技术及应用”课程为例,介绍了基于喷泉码的分布式云存储教学系统开展分层次实验教学的具体案例——传统三副本+TCP模式分布式云存储系统的实现与喷泉码+UDP模式分布式云存储系统的实现。实践表明,通过该系统的使用,学生可以有效将理论学习与实际应用相结合,锻炼自身编程能力和工程实践能力。
In order to meet the requirements of new engineering construction and course teaching for the Internet of Things,a distributed cloud storage teaching system based on fountain codes is proposed by combining the advanced knowledge in the field of storage and erasurecorrecting codes.The system contains rich teaching content and flexibly combines transport layer protocol with fountain codes characteristics for the Internet of Things.Taking the course of“Internet of Things Technology and Application”in Lanzhou University as an example,this paper introduces a specific case of hierarchical experimental teaching which is carried out by using the distributed cloud storage teaching system based on fountain codes.Both the traditional distributed cloud storage system,which is based on three copies of each data and transmission control protocol(TCP),and the distributed cloud storage system,which is based on fountain codes and user datagram protocol(UDP),are implemented.The practice results show that through the use of this system,students can effectively combine theoretical study with practical application and exercise their programming ability and engineering practice ability,so as to achieve the purpose of improving the teaching quality of the course for the Internet of Things.
