@techreport{bjrner2007models, author = {Bjørner, Nikolaj}, title = {Models and Software Model Checking of a Distributed File Replication System}, year = {2007}, month = {June}, abstract = {With the Distributed File System Replication component, DFS-R, as the central theme, we present selected protocol problems and validation methods encountered during design and development. DFS-R is currently deployed in various contexts; in Windows Server 2003-R2, Windows Live Messenger (Sharing Folders), and Windows Vista (Meeting spaces). The journey from an initial design sketch to a shipped product required mainly the dedicated effort of testers, developers, program managers, and several others; but in some places cute problems related to distributed consensus and software model-checking emerged. This paper presents a few of these, including a distributed garbage collection problem, distributed consensus problems for reconciling tree-like data structures, using model-based test case generation, and the use of software model checking in design and development process.}, publisher = {Springer-Verlag}, url = {http://approjects.co.za/?big=en-us/research/publication/models-and-software-model-checking-of-a-distributed-file-replication-system/}, pages = {23}, number = {MSR-TR-2007-75}, }
