In many cases, a mobile device has access only to data that is stored locally, and much of that data arrives via replication from other devices, PCs, and services. Given portable devices with limited resources, weak or intermittent connectivity, and security vulnerabilities, data replication serves to increase availability, reduce communication costs, foster sharing, and enhance survivability of critical information. Mobile systems have employed a variety of distributed architectures from client–server caching to peer-to-peer replication. Such systems generally provide weak consistency models in which read and update operations can be performed at any replica without coordination with other devices. The design of a replication protocol then centers on issues of how to record, propagate, order, and filter updates. Some protocols utilize operation logs, whereas others replicate state. Systems might provide best-effort delivery, using gossip protocols or multicast, or guarantee eventual consistency for arbitrary communication patterns, using recently developed pairwise, knowledge-driven protoco | | 出版日期 | Book 2008 | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-031-02477-1 | | isbn_softcover | 978-3-031-01349-2 | | isbn_ebook | 978-3-031-02477-1Series ISSN 1933-9011 Series E-ISSN 1933-902X | | issn_series | 1933-9011 | | copyright | Springer Nature Switzerland AG 2008 |
