Abstract
Content Delivery Network (CDN) offers faster transmission of massive content from content providers to users using servers that are distributed geographically to offer seamless relay of service. However, conventional CDN is not capable of catering to the larger scope of demand for data delivery, and hence cloud-based CDN evolves as a solution. In a real-world scenario, each requested content has different popularity for different users. The problem arises with deciding which content objects should be placed in each content server to minimize delivery delays and storage costs. A review of existing approaches in cloud-based CDN shows that yet the problem associated with content placement is not solved. In this regard, a precise strategy is required to select the contents objects to be placed in a content server to achieve higher efficiency without affecting the CCDN performance. Therefore, the proposed system introduces a novel architecture that addresses this practical problem of content placement. The study considers placement problem as optimization problem with the ultimate purpose of maximizing the user content requests served and reducing the overall cost associated with content and data delivery. With an inclusion of a bucket-based concept for cache proxy and content provider, a novel topology is constructed where an optimal algorithm for placement of content is implemented using matrix operation of row reduction and column reduction. Simulation outcome shows that the proposed system excels better performance in contrast to the existing content placement strategy for cloud-based CDN.
Highlights
In the area of Content Delivery Network (CDN), the prime target is to offer a seamless relay of data and services associated with the delivery of contents by the content provider to a destined user [1]
There is a need to carry out an investigation in order to offer a cost-effective solution in terms of modelling content placement approach with a target to offer a higher degree of performance of content delivery in cloudbased CDN
This paper has presented a novel framework where a unique architecture towards cost modelling is carried out for content placement
Summary
In the area of Content Delivery Network (CDN), the prime target is to offer a seamless relay of data and services associated with the delivery of contents by the content provider to a destined user [1]. There is always a dependency of appropriate resources to perform maintenance of such servers [3] To sort out this problem, the content providers are seeking an alternative option of hosting the CDN over the cloud environment with much cost-effective solution [4]. It is noticed that the majority of the research work is focused on performing optimization approaches towards solving the problems associated with effective placement of contents in the presence of low usage of resources [8]. There is a need to carry out an investigation in order to offer a cost-effective solution in terms of modelling content placement approach with a target to offer a higher degree of performance of content delivery in cloudbased CDN. The significant contribution of this paper is highlighted as follows:
