Mistore: A distributed storage system leveraging the DSL infrastructure of an ISP

Abstract

International audience—Internet Service Providers furnishing cloud storage services usually rely on big data centers. These centralized architectures induce many drawbacks in terms of scalability, reliability, and high access latency as data centers are single points of failure and are not necessarily located close to the users. This paper introduces Mistore, a distributed storage system aiming at guaranteeing data availability, durability, low access latency by leveraging the Digital Subscriber Line infrastructure of an ISP. Mistore uses the available storage resources of a large number of home gateways and points of presence for content storage and caching facilities reducing the role of the data center to a load balancer. Mistore also targets data consistency by providing multiple types of consistency criteria on content and a versioning system allowing users to get access to any prior versions of their contents. Mistore validation has been achieved through extensive simulation

Main Issues in Big Data Security

“…For instance, in [30] the authors propose a solution with which to achieve high availability by having multiple active NameNodes at the same time. Other solutions are based on creating a new infrastructure of the storage system so as to improve availability and fault tolerance [31,32].…”
