Center node: "double circulant minimum storage regenerating codes"
  Abstract: Abstract—Storage optimization in distributed environments isa major concern when talking about availability in this kind ofschemes. Although replication is the most used option, erasurecoding is a more optimized one.However, erasure coding uses a lot of bandwidth to replaceone node. In a dynamic scheme, where nodes enter and leavethe system frequently, bandwidth use could be an importantdrawback.Regenerating Codes introduced by Dimakis et al. minimizethe code repair problem by applying Network Coding to thedistributed storage scheme. However ﬁnding the coefﬁcients forthe linear combinations used to replace a node is not easy,specially for the systematic case, and must be calculated for eachnew node fail.For the special case when the dimension k and the redundancyn k of the system are the same, and the number of nodesparticipating in the regeneration phase is d = k+1, we purposea new optimal family of Minimum Storage Regenerating codeswhere coefﬁcients are precalculated and node regeneration hasfew computational requirements.This new family is connected to classical Double circulant codeswhich are a special case of Quasi-cyclic codes.
