用于低距离文件同步的有效协议

Effective protocols for low-distance file synchronization

Aleksandr Chuklin

摘要:

假设我们有两个类似的文件存储在不同的计算机上。我们需要将文件从第一台计算机发送到第二台计算机,以尽量减少传输的比特数。本文提出了一个调查的结果已知的情况下,当文件是“相似”的意义上的汉明距离的这种通信复杂性问题。本文主要对20世纪90年代和21世纪初不同作者所取得的成果进行了系统的整理,并讨论了它与编码理论、散列算法以及计算机科学其他领域的联系。在特定情况下,我们提出了一些改进以前的建设。

英文摘要:

Suppose that we have two similar files stored on different computers. We need to send the file from the first computer to the second one trying to minimize the number of bits transmitted. This article presents a survey of results known for this communication complexity problem in the case when files are "similar" in the sense of Hamming distance. We mainly systematize earlier results obtained by various authors in 1990s and 2000s and discuss its connection with coding theory, hashing algorithms and other domains of computer science. In particular cases we propose some improvements of previous constructions.
