    • A system for upgrading software has multiple clients coupled to an upgrade server. The clients store an old version of software. The upgrade server stores both the old version of software and a new version of software. The upgrade server creates an upgrade file from the old and new versions of the software such that the upgrade file is smaller than the new version. The upgrade server compares old character strings from the old version with new character strings from the new version to identify matching sections. The upgrade server derives a two-dimensional table containing multiple entries, whereby each entry represents a length of a longest common substring beginning at a first position in the old character string and at a second position in the new character string. The upgrade server then ascertains the longest common substring from the table. The upgrade server inserts headers into the upgrade file to distinguish between matching and non-matching sections. For matching sections, only the header is included and the section is omitted. The clients receive the upgrade file and begin processing the file to reconstruct the new version of software from the new sections included in the upgrade file and from the matching sections obtained locally from the stored old version of software.
    • 用于升级软件的系统具有耦合到升级服务器的多个客户端。 客户端存储旧版本的软件。 升级服务器存储旧版本的软件和新版本的软件。 升级服务器会从旧版本和新版本的软件创建升级文件,以便升级文件小于新版本。 升级服务器将旧版本的旧字符串与新版本的新字符串进行比较,以识别匹配的部分。 升级服务器导出包含多个条目的二维表,其中每个条目表示从旧字符串中的第一位置开始的最长公共子字符串的长度,并且在新字符串中的第二位置。 然后升级服务器从表中确定最长的公共子串。 升级服务器将标头插入升级文件,以区分匹配和不匹配的部分。 对于匹配部分,仅包括标题,并省略该部分。 客户端收到升级文件,并开始处理该文件,以从升级文件中包含的新部分以及从存储的旧版软件本地获取的匹配部分重新构建新版本的软件。
