P2PWeb: A Client/Server and P2P hybrid architecture for content delivery over internet

Abstract

In the domain of content delivery over Internet, each of the Client/Server and P2P communication modes has its pros and cons. In this scope, hybrid network architectures have been recently proposed as a relevant solution. In this paper we propose a new hybrid architecture that is called P2PWeb, between the centralized client/server and the non-centralized P2P architectures for content delivery. The main objective of this proposal is to reduce the load over the server in order to provide a better Quality of Service (QoS) for the end-users. A new P2PWeb communication protocol has been implemented and deployed to reach the objective. The experimentation results and the performance evaluations that we have made show the efficiency of the proposed system in terms of QoS evaluations.

Video Dissemination in Untethered Edge-Clouds: A Case Study

“…The potential of hybrid CDN-P2P architectures is well acknowledged by large CDN providers, e.g., see [12]. Some architectures combine servers and P2P (Internet) links [5,24], but do not directly account for proximity to end users. Cloudlets, on the other hand, are lightweight servers deployed at the edge of the network, e.g., as part of hybrid CDN-P2P architectures [25], as relays to perform video processing before uploading data to the central cloud [20], or to deliver geo-based multi-player content and interaction [23].…”

Using Edge-Clouds to Reduce Load on Traditional WiFi Infrastructures and Improve Quality of Experience

“…Content Delivery Networks (CDN) emerged with the objective of improving the distribution of content to end-users by providing high data availability, reduced latency and increased network bandwidth. There is a substantial body of research on CDNs, namely using hybrid server/P2P-based architectures (e.g., [5,18] and more recently [13]), focusing mostly on traditional networks. Here, we are interested in providing these infrastructures for mobile edge-clouds and in verifying whether some of the performance gains reported in the literature can be transposed to this context.…”

Client/Server and Peer-to-Peer hybrid architecture for adaptive video streaming

“…In this section we present the architecture P2PWeb [1] which is also hybrid architecture between P2P and C/S architecture, but it treats the above two issues differently. Then, we explain its network protocols.…”

“…Besides, it is not easy to fairly determine the contribution of each peer, which may also affect the reliability of the system. This is why different researches trend to propose hybrid architectures between C/S and P2P for video streaming [1,2,3]. On the other hand, and from a video transfer point of view, HTTP streaming gains a lot of attention today as a form of delivery of internet video.…”

“…We will mainly concentrate on extending DASH streaming from a traditional C/S communication model, towards P2P communication model based on the hybrid architecture that has been already proposed in [1] and that is entitled P2PWeb.…”
