Zfec. http://allmydata.org/trac/zfec. an "erasure code", or "forward error correction code". The most widely known example of an erasure code is the RAID-5 .
tahoe-lafs/zfec. Alexander Thomasian. PDF | Over the past five years, large-scale storage installations have required fault-protection beyond RAID-5, leading to a flurry of research on and. | Find, read and cite .
New in version 3.0.0. The ZFEC class provides forward error correction compatible with the zfec library. Forward error correction takes an input and creates . This package is a fork of zfec library, which is largely based on the old “fec” library by Luigi Rizzo et al., which is a mature and optimized implementation of erasure .
zfec是一种前向纠删码，用于给原始数据增加冗余信息，以提高数据的安全性。zfec提供了诸如c、python等语言的接口。A pure Rust implementation of the Zfec library. The general concept of Zfec is to break a message into blocks, or “chunks”, then generate additional chunks with parity information that can be used to identify any missing chunks.
Zfec shows good performance on different machines and with different values of K and M. It also has a nice small memory footprint. API. Each block is associated with "blocknum". The blocknum of each primary block is its index (starting from zero), so the 0'th block is the first primary block, which is the first few bytes of the file, the 1'st . 一、ZFEC源码解析. zfec是一种前向纠删码，用于给原始数据增加冗余信息，以提高数据的安全性。. zfec为我们同时提供了C和Python接口。. zfec源代码下载地址：. zfec 是Tahoe（一个基于云的文件系统）中纠删码的一个模块，其中的fec 模块是核心部分，实现了基于范德 .Simple fuse filesystem that can be used to get an erasure-coded view on a filesystem. Erasure-coding provides a way to efficiently distribute data over several storage locations such that an arbitrary set of (say) 3 locations can be used to completely recover the data. zfec-fs uses the erasure coding algorithm zfec, which is part of Tahoe-LAFS.

Either you need to push your commits and/or your tags, or the information about the package's VCS are out of date. A common cause of the latter issue when using the Git VCS is not specifying the correct branch when the packaging is not in the default one (remote HEAD branch), .
It is much faster to use a * multiplication table. * * USE_GF_MULC, GF_MULC0 (c) and GF_ADDMULC (x) can be used when multiplying * many numbers by the same constant. In this case the first call sets the * constant, and others perform the multiplications. A value related to the * multiplication is held in a local variable declared with USE_GF_MULC . zfec模块是基于纠删码（Ereasure Code）的python实现方式，纠珊码作为通信领域的一种重要的错误恢复技术，同时也成为了具有抗灾能力(比如数据被删除后恢复、数据存储出错后如何纠错)的数据存储服务的核心技术。zfec源码实现的其实是经典的Reed-solomon Ereasure Code的 . 什么是FEC？. 前向纠错码（FEC）和信道编码是在传输信道可靠性不高、强噪声干扰信道中进行数据传输时，用来控制接收数据包误码率（丢包、乱码）的一项技术。. 我们的世界充满了噪声。. 噪声影响一切，包括数据传输和通信系统，无法摆脱。. 光通信系 .

Copy Ensure you're using the healthiest python packages . The algorithm in the zfec package has a similar effect, but instead of recovering from the loss of only a single element, it can be parameterized to choose in advance the number of elements whose loss it can tolerate. This package is largely based on the old "fec" library by Luigi Rizzo et al., which is a mature and optimized .python3-zfec fast erasure codec, with Python 3 bindings.
