“…In [9], the authors proposed an object replacement algorithm by investigating the aggregate effect of placing multiple versions of the same multimedia object. Another aspect that affects the performance of transcoding-enabled storage systems is the storage distribution placement, which has been well studied [29,19,4,16].…”

Together with the information explosion era comes the problem of high energy consumption in data centers. Among the various components of a data center, storage is one of the biggest energy consumers. Many efforts have been put on reducing energy consumptions of data centers/storage systems, from server workflow management to storage data allocation. However, most works focus on local storage systems and pay no attention to other structures of storage systems. With the exponential expanding on both the depth and width of the Internet, wide-area storage systems attract more and more attention as they are reliable, loadbalancing, and easy to collaborate. In this paper, we study the energy consumption in wide-area storage systems by using multimedia objects as our special application area. We develop a multimedia object distributing algorithm based on the access pattern to multimedia objects and the topology of storage systems. We also present an in-depth analysis that provides valuable insight into the characteristics of multimedia object distribution strategies and leads to precision guarantees.

“…Toward this direction, the appropriate placement of surrogates to locations that are closer to end users is considered an important challenge in CDNs [4]. While the problem has been studied extensively in traditional CDNs (e.g., [5][6][7][8], etc. ), these results cannot be directly applied for cloud-based CDNs [2,9].…”

Over the last years, the content delivery network (CDN) market has been witnessing globally an increase in the development of cloud-based CDNs, as they constitute a viable and cost-effective alternative to traditional commercial CDNs. Towards that direction, Social-Aware Virtual Network Embedding (SAViNE) for wireless content delivery within the OpenLab project aims at establishing, assessing, and prototyping a novel framework for deploying a CDN over the wireless cloud. Specifically, the goal of SAViNE is to provide experimental validation of the efficiency of social network analysis (SNA) -inspired surrogate server placement strategies, devised for fostering content delivery. The proposed framework has been integrated with the OpenLab experimental facilities, providing a run-time environment for CDN deployment, operation, and performance evaluation over the wireless environment. The framework's feasibility and scalability is experimentally validated. The study is complemented with repeatability evaluation of experimental measurements, related to the resulting CDN's operational efficiency.

“…It was shown that placing more mirrors beyond a certain number offered little performance gain. Different from the above studies which explored the optimization of retrieval cost only, Xu et al [12] and Jia et al [13] further took the update cost into consideration. Cidon et al [6], on the other hand, used the total storage and retrieval cost as the objective metric of optimization.…”

On replica placement for QoS-aware content distribution

Abstract-The rapid growth of time-critical information services and business-oriented applications is making quality of service (QoS) support increasingly important in content distribution. This paper investigates the problem of placing object replicas (e.g., web pages and images) to meet the QoS requirements of clients with the objective of minimizing the replication cost. We consider two classes of service models: replica-aware service and replica-blind service. In the replica-aware model, the servers are aware of the locations of replicas and can therefore direct requests to the nearest replica. We show that the QoS-aware placement problem for replica-aware services is NP-complete. Several heuristic algorithms for efficient computation of suboptimal solutions are proposed and experimentally evaluated. In the replica-blind model, the servers are not aware of the locations of replicas or even their existence. As a result, each replica only serves the requests flowing through it under some given routing strategy. We show that there exist polynomial optimal solutions to the QoS-aware placement problem for replicablind services. Efficient algorithms are proposed to compute the optimal locations of replicas under different cost models.
