摘要
着眼于移动应用数据共享,探讨了整合移动应用产品线的需求、实现方法和现状,研究了移动云存储服务主流架构、文件同步协议和优化技术这些关键技术。从优化同步效率、节约同步流量着眼,设计了测试床,评估了目前主流移动云服务文件分块、捆绑、冗余消除、增量同步和数据压缩5项优化技术的实现情况,测量了文件传输时各服务的协议开销和同步完成时间,用于评估各服务的移动客户端性能。实验结果显示,移动云存储服务的优化技术对移动客户端服务性能有决定性的作用。
The motivation of the research in this paper is the demand of data sharing. We discuss the demands, implementation and current situation of integrating product line, leading to the study of key technologies including mainstream architecture, file synchronization protocol and capabilities for optimization. To make synchronization more efficient and economize synchronization traffic, we design a test bed that evaluates the implementation of five capabilities—chunking, bundling, de-duplication, delta encoding and compression— and measures the performance of mobile clients in terms of protocol overhead and synchronization completion time. The results show the capabilities significantly affect mobile client service performance.
