a hybrid approach for content replication improvement in content delivery networks

Adaptive Replication in Distributed Content Delivery Networks

We address the problem of content replication in large distributed content delivery networks, composed of a data center assisted by many small servers with limited capabilities and located at the edge of the network. The objective is to optimize the placement of contents on the servers to offload as much as possible the data center. We model the system constituted by the small servers as a loss...

Replication Algorithms for Scalable Streaming Media in Content Delivery Networks

1. Introduction CDN (Content Delivery Networks) improves end-user performance by replicating web contents on a group of geographically distributed servers. However, current replica strategies in CDN are to simply and repeatedly keep the complete replica of the original object on many content servers. Disadvantages of this method are as follows: to repeatedly store the same large-sized object in...

Architecture of Hybrid Mobile Social Networks for Efficient Content Delivery

Content delivery is one of the most important technologies used in Mobile Social Networks (MSNs). Smart devices could enable mobile users to create and use a rich set of services through available resources in the surrounding environment opportunistically. This paper presents the framework of distributed buffer storage aided hybrid Mobile Social Networks (MSN). Based on this, we propose a new s...

Improve Replica Placement in Content Distribution Networks with Hybrid Technique

The increased using of the Internet and its accelerated growth leads to reduced network bandwidth and the capacity of servers; therefore, the quality of Internet services is unacceptable for users while the efficient and effective delivery of content on the web has an important role to play in improving performance. Content distribution networks were introduced to address this issue. Replicatin...

Content Delivery Networks - Preamble

Content Delivery Networks

This document reports experimental results on the delivery of HTTP Adaptive Streaming (HAS) content over interconnected Content Delivery Networks (CDNs). Specifically, the implications of CDN request routing between CDNs and HTTP redirection on the quality of delivered HAS content are investigated.
