This thesis examines the provision of on-demand multimedia streaming services using clusters of commodity PCs. In the proposed HammerHead multimedia server cluster architecture, a dynamic content replication policy is used to assign non-disjoint subsets of the presentations in a
Dynamic RePacking: A Content Replication Policy for Clustered Multimedia Servers
Dynamic replication is a technique that can be used by clustered multimedia servers to evaluate the demand for individual streams and selectively replicate or move content to facilitate load balancing. In this paper we explain the motivation for using dynamic replication and prov
An E cient Scheme for Dynamic Data Replication
This paper presents an eecient scheme for dynamic replication of data in distributed environments. The aim of the scheme is to increase system performance by intelligent data placement so as to optimize the message traac in the network. Research in the recent past has comparative
Dynamic data replication in LCG 2008
To provide performant access to data from high energy physics experiments such as the Large Hadron Collider (LHC), controlled replication of files among grid sites is required. Dynamic replication in response to jobs may also be useful, and has been investigated using the grid si
The impact of data replication on job scheduling performance in the Data Grid
In the Data Grid environment, the primary goal of data replication is to shorten the data access time experienced by the job and consequently reduce the job turnaround time. After introducing a Data Grid architecture that supports efficient data access for the Grid job, the dynam
Dynamic Data Grid Replication Strategy Based on Internet Hierarchy
In data grid, large quantity of data files is produced and data replication is applied to reduce data access time. Efficiently utilizing grid resources becomes important research issue since available resources in grid are limited while large number of workloads and large size of
Dynamic Fitness Landscapes in Molecular Evolution
We study self-replicating molecules under externally varying conditions. Changing conditions such as temperature variations and/or alterations in the environment’s resource composition lead to both non-constant replication and decay rates of the molecules. In general, therefore,
On Improving the Performance Dependability of Unstructured P2P Systems via Replication
The ever-increasing popularity of peer-to-peer (P2P) systems provides a strong motivation for designing a dependable P2P system. Dependability in P2P systems can be viewed from two different perspectives, namely system reliability (the availability of the individual peers) and sy
Dynamic Data Grid Replication Algorithm Based on Weight and Cost of Replica
Data Grid is composed of a large number of distributed computation and storage resources to facilitate the management of the huge distributed and sharing data resources efficiently. Dynamic replication can reduce the file storage time and use the grid resources effectively in a D
Improvement of Job Scheduling and Tow Level Data Replication Strategies in Data Grid
With the development of grid computing, Data Grid, as an important branch of Grid Computing focuses on supporting an efficient management mechanism for controlled sharing and large amounts of distributed data. Data intensive jobs are one major kind of jobs in Data Grid, and their
