Continuing along with our ongoing efforts in developing a framework integrating the concepts of component-based design for fault-tolerance and category-theory-based modular composition, in this paper, we present a component-based design of a fault-tolerant multimedia protocol and composition of resulting components through correct-by-construction approach. Essentially, we show how a fault-intolerant program is transformed into a fault-tolerant program with components providing for dependability, namely, detectors and </span>correctors. We first show the correctness of the fault-tolerant program, and then to achieve a rigorous composition out of the fault-intolerant program and fault-tolerant components, we utilize concepts of category theory to develop component-based fault-tolerant program. We illustrate the overall development of a fault-tolerant program with a case study of the label distribution protocol (LDP). The compositional specification and its correctness for the FT-LDP has been realized through a mechanized formal tool called Specware.</p></div>","PeriodicalId":101062,"journal":{"name":"Real-Time Imaging","volume":"9 6","pages":"Pages 401-422"},"PeriodicalIF":0.0,"publicationDate":"2003-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.rti.2003.09.009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72851573","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}
