摘要

在本文中，我们研究了不同的数据库同步/复制策略，并比较了它们在延迟和交换数据量方面对卫星链路的适用性。早期的工作已经研究了这些算法在地面网络上的性能;但是，地球同步卫星造成的延迟尚未考虑在内。利用卫星链路数据库端节点仿真试验台，对不同的同步算法进行了比较。

Performance of database synchronization algorithms via satellite

In this paper, we examine different database synchronization/replication strategies and compare their suitability for satellite links in terms of latency and exchanged data volume. Earlier works have investigated the performance of these algorithms over terrestrial networks; however, the delay caused by a geostationary satellite has not been taken into account yet. A test-bed emulating a satellite link with database end nodes was used to compare different synchronization algorithms.
