摘要:
A random permutation code is described which provides efficient repair of data nodes. A specific implementation of a permutation code is also described, followed by description of a MISER-Permutation code. Finally, an optimal repair strategy is explained that involves an iterative process of downloading the most effective available parity data, updating costs of remaining parity data, and repeating until the data is recovered.
