Multipath Routing Over Star Overlays for Quality of Service Enhancement in Hybrid Content Distribution Peer-to-Peer Networks

Abstract

Content Delivery Networks (CDN's) have emerged as a flexible and decentralized solution to maintain and transfer large volumes of data. CDN's are distributed systems that maintain a distributed storage on a large number of servers at various locations distributed all over the world and a service network system for dissemination of content such as videos and software with high content dissemination efficiency, enhanced QoS metrics, and reduced network load. In the wake of enormous growth in live video streaming traffic on the Internet, CDN's face challenges in meeting video traffic demands of users. As a remedy, hybrid CDN-P2P networks are being deployed to allow P2P networks to share the content delivery load of CDN's providing the reliability and the performance of the CDN's, and the scalability and the low cost of P2P networks. In this paper, by simulation under a realistic model, we show that multipath routing in star overlay networks achieves a high degree of load balancing, scalability, throughput enhancement, and reduces buffer requirements and network bottlenecks. As these algorithmic properties are highly desirable for hybrid CDN-P2P networks, we establish the viability of the star overlay networks as an edge network for hybrid CDN-P2P networks to meet their content delivery quality of service requirements.

“…This is due to the fact that in a highly dynamic environment where variables like wireless channel conditions, traffic, and energy restrictions are always changing, effective decision-making is crucial. With WMSNs, the Software Defined Networks (SDN) [35,36,37,38] is a dynamic optimization approach that is effective. Node radio transmission often uses the bulk of the network's power in a WMSN [39].…”
