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 implementation of erasure -coding. The zfec package makes several changes from the original "fec" -package, including addition of the Python API, refactoring of the C -API to support zero-copy operation, a few clean-ups and optimizations -of the core code itself, and the addition of a command-line tool named -"zfec". |
