M. Preetha · International Journal for Research in Applied Science and Engineering Technology · 2019
Recent researches on erasure coding for distributed storages have shown us various error detection and correction methods and strategies.Several studies have shown distinct erasure codes for repair strategies ranges three.We propose a general mechanism that showcases the opportunity for possible repairs and examine how many different types of erasure codes benefit by being network aware.In order to guarantee data reliability, erasure codes have been used in distributed storage system.Nevertheless, this mechanism suffers from the repair problem that excess data are needed to repair a single failure, causes both high bandwidth consuming for the network and heavy computing load on the replacement node.To reduce repair traffic, researches pointed out the tradeoff between storage and repair traffic which proposed regenerating codes by combining network coding.In this paper, determine the set of feasible repair for random linear network coding (RLNC) and system of efficient checks using techniques from the arsenal of dynamic programming.
