Abstract
This paper addresses interconnection contracts in content provisioning scheme with partial cloud migration. Model for traffic workload of such scheme based on content popularity factor is introduced. Monte Carlo simulation for bandwidth demand estimation is used. Cost analysis of content provider’s resources utilization regarding average requests’ rejection rate is observed. The performance analysis of content provider’s incentive for partial cloud migration is applied. Three interconnection contracts are analysed: Revenue Sharing, Cost Sharing and Wholesale Price contract. Obtained results show that partial cloud migration can reduce both content provider’s costs and average requests’ rejection rate. Under observed constellation, Revenue Sharing contract may represent satisfying solution for both providers.DOI: http://dx.doi.org/10.5755/j01.eie.22.6.17230
Highlights
The permanent growth of Internet traffic, caused by emerging high bandwidth demanding contents such as video on demand, High Definition Television (HDTV), real time video, online gaming, file sharing and cloud computing, is supported by bandwidth improvement of all participants in content provisioning process
According to different cloud pricing schemes, revenues and assessed costs, we evaluate three interconnection pricing contracts between content and service provider
Number of request served by the content provider’s server per time slot in (4) is denoted by nicp ; number of requests accomplished by the cloud Content Delivery Network (CDN) is denoted by nicl and number of rejected requests is denoted by nirej
Summary
The permanent growth of Internet traffic, caused by emerging high bandwidth demanding contents such as video on demand, High Definition Television (HDTV), real time video, online gaming, file sharing and cloud computing, is supported by bandwidth improvement of all participants in content provisioning process It includes content providers, service providers, Content Delivery Network (CDN) and customers [1]. Cloud providers maintain large-scale data centres to offer storage and computational resources at a relatively low cost [9]−[11] These providers enable different pricing plans, such as reservation, on-demand and spot market [12]. Three interconnection contracts with partial cloud migration are analysed: Revenue Sharing, Cost Sharing and Wholesale Price contract.
