我们考虑使用擦除代码在网络分布式存储系统中同时修复几个节点故障的问题。虽然已经研究了所有参与维修协作的节点的协作维修概念，但我们提出了两个代码构造，以说明维修可以调用不同级别的协作水平，我们称之为部分协作。我们考虑极端情况：当存储分别为维修带宽时，则最小。
We consider the problem of repairing simultaneously several node failures in a networked distributed storage system using erasure codes. While the notion of collaborative repair, where all nodes participating in the repair collaborate among each others, has been studied, we propose two code constructions that illustrate that the repair could be invoking instead different levels of collaboration, which we call partial collaboration. We consider extreme cases: when the storage, respectively the repair bandwidth, are minimum.
