An Overview of Media Streams Caching in Peer-to-Peer Systems

Abstract

Nowadays, the idea of media contents streaming through the Internet has become a very important issue. On the other hand, full caching for media objects is not a practical solution and leads to consume the cache storage in keeping few media objects because of its limited capacity. Furthermore, repeated traffic which is being sent to clients wastes the network bandwidth. Thus, utilizing the bandwidth of the network is considered as an important objective for network administrators. Media objects have some characteristics that have to be considered when a caching algorithm is going to be performed. In this paper, recent approaches that have been proposed for media streams caching in peer-to-peer systems are reviewed.

Intelligent Cooperative Web Caching Policies for Media Objects Based on J48 Decision Tree and Naïve Bayes Supervised Machine Learning Algorithms in Structured Peer-to-Peer Systems

“…Media objects have some characteristics that have to be considered when a caching algorithm is to be performed. In the work of Yasin et al (2013), an overview of media streams caching in peer-to-peer systems has been presented, where the characteristics of media objects have been listed. In this work, we focus on media objects caching because there is no need to consider the characteristics of consistency where web objects are updated.…”

“…The proposed approaches take the advantages of both client-server and peerto-peer systems where peers' caches contents are shared in order to enhance the performance of the web caching policy. There are two different ways for configuring a peer-to-peer system that are unstructured peer-to-peer system and structured peer-to-peer system (Xu et al, 2010;Yasin et al, 2011;Yasin et al, 2013). In this work, a structured peer-to-peer system is adopted where a pre-existing infrastructure such as having access points is required.…”
