Replicache: a New Approach to Scalable Network Storage System for Large Objects

چکیده
This paper comtemplates two important information-provisioning pradigms-caching and replication, and proposes a new approach on network storage system in order to meet the increasing demands for large les. The key idea of our system is to have two tailor-made servers for large and small object, respectively. Modiied proxy cache is responsible for store and deliver small objects. For large objects, we introduce a replication mechanism. By replicating large objects in a dedicated server and relaying through a proxy cache, storage can be fully utilized. Large objects can be accessed without a priori knowledge of server location. Our system provides a scalable solution to the continuing growth of traac volume while it retains transparency for users. It is also designed to ensure compatibility with existing networking standards, applications and system software.

Therefore, in this paper, a new method is proposed for energy management of the distribution networks in order to show that how presence of the energy ...
متن کاملHybrid Regenerating Codes for Distributed Storage Systems
Distributed storage systems are mainly justified due to their ability to store data reliably over some unreliable nodes such that the system can have long term durability. Recently, regenerating codes are proposed to make a balance between the repair bandwidth and the storage capacity per node. This is achieved through using the notion of network coding approach. In this paper, a new variation ...
