Mr Mehran Gharmeei is going to defense his Phd thesis on “Designing mechanisms for hybrid CDN_P2P Networks relying on economic mechanism design theory” on Monday January 18, 2016. The session will be held in Phd defense hall, Computer Engineering Department, Iran University of Science and Technology, Tehran, Iran.
Today’s, the application of Internet in our lives has grown in such a way that the economy, communication, health, politics and even security of human depends on it. Still, the main application of Internet is to carry an increasing quantity of bulky and sensitive content. Content Delivery Networks (CDN) and Peer to Peer (P2P) network are two known architectures for distribution of the content and have complementary advantages and flaws. Hybrid CDN-P2P networks (HCDN) blend these architectures and benefit from their advantages. This PhD. research is devoted to designing the required mechanisms for HCDNs and aims to deliver the content distribution service with high quality, low price, high scalability, and ease of management to content providers and end-users. Fundamental mechanisms of HCDNs include Request Routing (RR), Resource Allocation (RA), Replica Placement (RP) and Multi-source Multicasting and have many correlated objectives and constraints. Since designing the intended mechanisms demand integration of the economics of the content distribution market into the coordination mechanisms of the HCDN architecture, this study relies on the Economic Mechanism Design Theory which introduces a robust mathematical framework to design high performance, efficient solutions for complicated problems.
Contributions of this thesis include designing novel functional mechanisms to setup HCDNs or upgrade traditional CDNs to HCDNs and optimizing the performance and economics of HCDNs through wise mechanism design.
Outcomes confirm that, in practice it is possible to practically manage a commercial HCDN with proposed mechanisms. In particular, economics and the performance of content delivery in HCDNs is studied, and it is shown that through our mechanisms, it is possible to deliver higher quality of service to majority of end-users, improve the net profit of the HCDN provider and decrease the expenditures of the content provider simultaneously.
