Web固件升级使用FOTA(Firmware Over-The-Air)方式时,可以采用传输差分包的形式来减小升级包的大小,能够带来空口传输时间减小、降低终端功耗等优势。目前比较常见的算法有xdelta使用的Vcdiff及Bsdiff等。VcdiffVcdiff可以实现文件的差分并压缩的功能,当原文件为空时,则相当于对新的文件直接压缩。 WebIt turns out that rdiff uses a slightly better algorithm in terms of memory, but it creates a bigger patch (delta) file than either of bsdiff or xdelta3. xdelta3 creates the smallest patchfile, but it uses more memory to create the patch than rdiff does. So in terms of the created patch size, we have—xdelta3 < bsdiff < rdiff.
