A deterministic dynamic system is proposed to approximate the imbedded Markovian chain model of the CSMA system. Based on this approximation, the probability of overloading of the CSMA system due to impulsive input can be estimated, and the trajectory of the system states can be calculated. For engineering application purposes, a relaxation time is defined. Simulations are carried out which support the above-mentioned approaches.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132504308","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}

The main characteristics of the FDDI protocol are examined. The performance of FDDI-II is studied for scenarios including asynchronous traffic, synchronous traffic and isochronous traffic. The results make clear that basic FDDI meets the requirements imposed by traditional local area network (LAN) application and that from a performance point of view FDDI-II is an excellent candidate for complex communications environments. When compared to the distributed-queue-dual bus (DQDB) protocol, FDDI-II yields much better efficiency in traditional LAN applications.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123443255","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}

The end-to-end delay consists of the Datakit network, the device attached control unit (DACU), and host component delays. The echo response time is the amount of time it takes for a character to be echoed back by the host. To measure the end-to-end terminal-to-host delay and the Datakit contribution to the overall delay, two parallel experiments were set up. The first experiment provides direct dialing from a 3B2 computer into a LMU by passing Datakit, whereas the second test utilized the Datakit terminal-to-host network to access the LMU during the same time intervals. The experiments provide a considerable amount of data to evaluate the delay with and without the Datakit component. the 50th percentile echo response time clearly indicates that the Datakit contribution to the overall response time is around 50 ms with very little variance. The overall Datakit delay fluctuates between 35 ms and 70 ms.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123463666","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}

These requirements, while appearing light at first, can quickly become onerous if not carefully considered and built into a systematized approach to standards creating. The needs for test, verification, conformance, revision, and possibly certification all should be considered prior to any new LCN standardization undertaking.

There are two SAFENET standards. SAFENET I is based on the IEEE 802.5 LAN standard, while SAFENET II is based on the fiber distributed data interface (FDDI). The SAFENET physical topology is based on a dual counter-rotating ring architecture which provides many survivability features. The SAFENET program has been successful in defining a set of network profiles which will meet the requirements of Navy shipboard combat systems. These standards provide many advantages over current interconnection methods, including use of fiber optics, system survivability, and use of commercial standards.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"203 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116007903","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}
