This requires the underlying infrastructure to provide scalability, fault tolerance and fast response times. While replicating the services and the data they access across sites that are located in different geographic regions is a promising means to achieve these requirements, data consistency is challenging if data continuously changes and queries are dynamic by nature, as is typical for e-commerce applications.Thus, current WAN replication solutions either trade performance for data consistency or are notable to scale in wide-area settings. In this paper, we present a novel approach to provide performance and consistency for Internet services. One of the main contributions is an autonomic replica placement module that places data copies only on servers close to clients that actually need them. The goal is to find the right trade-off between fast local access and the overhead of keeping data copies consistent. As data access patterns might change over time, reconfiguration is done periodically and online, i.e., allowing sites to receive new data copies or drop data copies while at the same time transaction processing continues in the system.","PeriodicalId":397103,"journal":{"name":"2008 Symposium on Reliable Distributed Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121962208","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 proposed methodology uses the Fluid Stochastic Petri Net (FSPN) as modeling formalism, and compares the safety metrics estimated from the simulation of both the proposed and the legacy system models. It was applied to assess the safety properties of a new air traffic surveillance concept, named \"automatic dependent surveillance - broadcasting\" (ADS-B). As conclusions, the proposed methodology assured to assess the safety properties of systems based on the current safety critical system paradigm - especially concerning the air transportation system. Besides, the FSPN formalism provided important modeling capabilities and discrete event simulation allowing estimating the desired safety metrics. Finally, the ADS-B (proposed system) has significantly reduced the risks of separation losses between aircrafts if compared to the usual surveillance radar systems (legacy system) in air traffic control (ATC) environment.","PeriodicalId":397103,"journal":{"name":"2008 Symposium on Reliable Distributed Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129257975","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}

Such popularity is mainly because read-only transactions executing under snapshot isolation are never blocked or aborted. In partial replication, where each replica holds only a part of the database, transactions may require access to remote databases. Each remote read operation of the transaction must execute in a consistent global database snapshot as the local operations; if such a snapshot is not available, the transaction must be aborted. In this paper we are interested in the effects of distributed transactions on the abort rate of partially replicated snapshot isolation systems. We present a simple probabilistic analysis of transaction abort rates for two different concurrency control mechanisms: lock- and version-based. The former models the behavior of a replication protocol providing one-copy-serializability; the latter models snapshot isolation. Our analysis reveals that in the version-based system the execution abort rate decreases exponentially as the number of data versions available increases. As a consequence, in all cases considered, two versions of each data item were sufficient to eliminate aborts due to distributed transactions.","PeriodicalId":397103,"journal":{"name":"2008 Symposium on Reliable Distributed Systems","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122128761","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}
