High accuracy IEEE 1588 implementations require a well-coordinated hardware/software co-design. Processing of sophisticated control algorithms for the time speed of local clocks within synchronization slaves are particularly important. Hence, IEEE 1588 implementations should be tested with respect to certain performance indicators like control loop behavior and synchronization accuracy. Furthermore, interoperability with other devices and standard compliance also need to be considered. The achievable synchronization accuracy depends on environmental conditions, network load and network topology. A test system should be able to emulate these physical conditions. This requires a well-founded knowledge about influences on IEEE 1588 implementations caused by both, environmental conditions and network load. This could be a frequency drift of crystal caused by either temperature variations or mechanical stress. Unfortunately, the standard does not specify an expected behavior in such an environment. Due to lack of standardization and test methods, a system-wide guarantee for synchronization accuracy can only be given for proprietary closed systems. In this paper a reproducible test environment with the ability to emulate environmental conditions is presented, followed by an evaluation of two exemplary implementations. The possibility to guarantee synchronization accuracy with the help of appropriate certification tests in such a specific test environment will be demonstrated.","PeriodicalId":254081,"journal":{"name":"2010 IEEE International Symposium on Precision Clock Synchronization for Measurement, Control and Communication","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128469433","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}

It has some significant performance and scalability advantages, but at the cost of not allowing non-PTP-aware devices. This paper describes how a network having a common source of time can act as a distributed IEEE 1588 boundary, ordinary, or transparent clock, allowing the network to transport synchronization between portions of an IEEE 1588 network domain, and do this for any number of domains simultaneously. The network that acts as a distributed clock can be a PTP network supporting a profile that is different from that of the domains whose timing it is transporting. As one example, an IEEE 802.1AS network can act as a distributed IEEE 1588 boundary, ordinary, or transparent clock. As part of the discussion, the paper also shows that an IEEE 1588 boundary clock and peer-to-peer transparent clock are functionally equivalent in the manner in which they transport synchronization, and that the principal difference between the two is that the former invokes a best master clock algorithm (either default or alternate) and implements the full PTP state machine, while the latter does not. The concepts of distributed BC, TC, and OC, and the equivalence of the BC and peer-to-peer TC may be considered a new way of looking at the transport of synchronization in a network based on IEEE 1588.","PeriodicalId":254081,"journal":{"name":"2010 IEEE International Symposium on Precision Clock Synchronization for Measurement, Control and Communication","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114201905","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}
