“…The disjunction ratio of each parent set constructing the chromosome is calculated by the formula given in (4), where C i:j , the ratio of the number of common links of the paths of two parent nodes to path length of the parent i is obtained by the formula given in (3). In (4), K represents the number of substreams.…”

“…Although many successful P2P systems and approaches improving the performance of these systems have been proposed in the literature, such systems need to utilize Content Distribution Networks (CDNs) [3,40] or to support from Cloud servers [23,36] in order to provide acceptable QoE. Hence, they are still open for improvement of sophisticated solutions to the problems such as peer churn, limited capacities of peers or congestion to minimize the need of outsource support, thus, reducing the cost.…”

In peer-to-peer (P2P) video streaming applications, the Quality of Experience (QoE) obtained by peers may vary according to the level of network congestion on the path between the peer and its parents. In this paper, we have proposed a parent selection approach for hybrid push-pull based video streaming systems, taking physical paths into account. In this approach, we proactively measured the disjunction of paths between peers and partners and chose the set of parents among partners having maximum disjoint paths by using a genetic algorithm at the beginning of the streaming session. The peers continue the paths of parent set to keep disjoint during streaming. The proposed system was tested on NS3 and the obtained results show that the proposed approach provides an increase up to 10 % in continuity index compared to hybrid push-pull based system which does not consider underlying network infrastructure. Furthermore, higher performance in terms of other parameters related to QoE such as Peak Signal to Noise Ratio (PSNR), reset count, and network related parameters such as video propagation success among peers and re-selection rates of new parents is observed with the proposed approach.

“…The main purpose of a CDN is to distribute contents over a set of web servers highly distributed around the world, so as to guarantee a reliable, scalable and efficient delivery of the contents to end users [7,8]. Let's give a real example to understand about CDN: A website is hosted on a web server that's located in Korea.…”

In the recent years, with the development of high-speed and broadband networking, the content delivery service has been grown up widely. There are a lot of providers for online streaming via content delivery network (CDN) and peer to peer (P2P) network, each having its own set of advantages and disadvantages. CDN provide excellent quality to end-users when the work load is within the provisioning limits. However, CDN servers are expensive to deploy and maintain. While P2P network has better scalability and less deployment costs, but the instability of dynamic peers, and the low performance when participated peers are insufficient are a bottleneck. So, by combining advantages of two system we will take advantage of both. In this paper, we propose the hybrid CDN-P2P structure for live video streaming over the Web in order to decrease the number of requests to CDN servers that means reduce the cost of transmission. Also by set up short timeout for request to server and split video into small chunk, our system has smaller end-to-end delay than unconnected mesh system in Seyyedi and Akbari (Hybrid CDN-P2P architectures for live video streaming: comparative study of connected and unconnected meshes. In: International symposium on computer networks and distributed systems, 2011). By set up a reality, we compare two metrics: the number of requests to CDN server and end-to-end delay with previous researches. Through experiment, we will show that a hybrid CDN-P2P approach is very effective approach in providing a live streaming service to the public.

“…In order to alleviate this cost issue, we propose to stop confining streaming to the single-server approach and propose an evolving streaming solution taking advantage of multiple types of content sources simultaneously, including cheap commodity devices (Set-Top boxes, end-users' devices, ISP's home-gateways) generally located at end-users' premises, with many of the costs covered by the end users). Indeed, hybrid systems (such as P2P-CDN) scale horizontally at cheaper costs compared to pure CDN solutions [1] [2]. However, HAS in distributed environment has not yet been enabled in pragmatic-enough ways that would convince CPs to use alternative solutions to CDNs [3].…”

Adaptive streaming protocols over HTTP (HAS), such as MPEG-DASH, have become the de-facto solutions to deliver video over the Internet. By avoiding buffer stalling, HAS increases end-user's Quality of Experience (QoE). These solutions always bind a client to one server. We propose to extend HAS capabilities to multiple-source streaming, which offers the opportunity to obtain higher QoE by exploiting expanded bandwidth and link diversity in distributed streaming infrastructures. We expose a pragmatic evolving DASH-compliant solution for dynamic adaptive Multiple-Source Streaming over HTTP (MS-Stream) that simultaneously utilizes several servers. We validated our approach using network profiles from DASH Industry Forum and Internet users. Our solution is compared to optimal -yet practically unfeasible-DASH solutions in multiple-source environments and over several QoE criteria. Results show the QoE gains of using MS-Stream against DASH; an online demonstration of our work is available.
