BMCloud: Minimizing Repair Bandwidth and Maintenance Cost in Cloud Storage

Explicit Code Constructions for Distributed Storage Minimizing Repair Bandwidth

Regenerating codes are a class of recently developed codes for distributed storage, that permit data recovery from any k of n nodes, and also have the capability of repairing a failed node by connecting to any d nodes and downloading an amount of data, termed the repair bandwidth, that is on average, significantly less than the size of the data file. These codes optimally trade the storage spac...

Maintenance Cost Analysis for Replacement Model with Perfect Minimal Repair

With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...

Cost-Bandwidth Tradeoff In Distributed Storage Systems

Distributed storage systems are mainly justified due to the limited amount of storage capacity and improving the reliability through distributing data over multiple storage nodes. On the other hand, it may happen the data is stored in unreliable nodes, while it is desired the end user to have a reliable access to the stored data. So, in an event that a node is damaged, to prevent the system rel...

Cost-minimizing Bandwidth Guarantee for Inter-datacenter Traffic

The emerging deployment of large-scale cloud applications incurs significant inter-datacenter traffic, which makes the scarce wide-area bandwidth across data centers become the performance bottleneck. To achieve the desirable network performance, bandwidth guarantee should be provided for the resulting inter-datacenter traffic. However, the existing bandwidth allocation methods mainly focus on ...
