{"title":"Migration from SERCOS III to TSN - Simulation Based Comparison of TDMA and CBS Transportation","authors":"Sebastian Szancer, Philipp Meyer, Franz Korf","doi":"10.29007/c5td","DOIUrl":"https://doi.org/10.29007/c5td","url":null,"abstract":"The communication infrastructure of industrial plants, vehicles and many other applications must provide more and more bandwidth, sometimes with strict timing requirements for the transmission of critical data. Time-Sensitive Networking (TSN) is a set of IEEE 802 Ethernet sub-standards that meet these requirements for a wide range of applications and communication requirements. Market relevance of TSN increases in different sectors. On the other hand, SERCOS III is an established Ethernet-based communication standard, which is used in particular in the field of industrial plants. With cost and limitations of SERCOS III in mind, this paper examines the migration from SERCOS III Time Division Multiple Access (TDMA) communication on the one side to Credit Based Shaping (CBS) communication on the other side. TSN supports both mechanisms. The analyses are performed with OMNeT++ simulation models. Migration recommendations are derived from the comparison of TDMAand CBS-based transportation of SERCOS III traffic.","PeriodicalId":159293,"journal":{"name":"OMNeT++ Community Summit","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124675880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teaching the concepts of simulation and modelling while letting the students obtain a hands-on experience during a 14-week (4h/week) period (single semester) is a challenging task. The diversity of the pre-knowledge of the participating students and the duration of the course are the main challenges that need to be addressed when organising such a course. This paper discusses the structure of this course and the best practices followed. The course adopts a methodology where lectures on concepts are mixed with INET based exercises that begin with simple topics and gradually moving into advanced topics.","PeriodicalId":159293,"journal":{"name":"OMNeT++ Community Summit","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131074945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
