A comprehensive analytical framework for VoD services in hybrid CDN-P2P systems

Abstract

Video on Demand services generate the Jargest amount of traffic in networks nowadays. Previous works have proposed integrating Content Delivery Networks (CON) and Peer-to-Peer (P2P) networks to satisfy this demand. However, their analytical methods do not consider al) the factors that affect the performance of these systems. Hence, we present a nove) comprehensive framework, based on a fluid mode), to evaluate VoD services over hybrid CDN-P2P systems. The proposed framework considers features of the service (e.g., size, coding-rate and popularity of the video), network attributes (e.g., upload data-rate capacity of servers and peers) and char acteristics of the behavior of the users (e.g., sojourn time, cooperativeness and frequency of random-seeks). Our framework allows a system to be evaluated under a wide variety of scenarios in terms of network-cost and Quality-of-Service (QoS) parameters and is flexible enough to mode) different resource allocation schemes, including a nove! scheme to distribute the upload network capacity. Despite the wide variety of considered factors, our framework is tractable and as accurate as discrete-models based on Markov chains.

A Review on Software Defined Content Delivery Network: A Novel Combination of CDN and SDN

“…The algorithm decide the range of sharing among peers, and the cost of selecting an edge server is also considered to increase the profit of P2P and decrease the cost of CDN. Torres-Cruz N et al [78] formulate a comprehensive network to get an optimized result by considering the feature of service, attributes of the network, and behavior of the users.…”

A cost‐efficient QoS‐aware analytical model of future software content delivery networks

“…In the literature, we also find works that introduce hybrid solutions blending CDN and P2P approaches 16,17,22‐24,26,27,30 . They combine CDNs and P2P networks taking profit of the advantages of both architectures, that is, the easy management and high QoS of CDNs and the low running costs and high scalability of P2P networks.…”
