“…On the other hand, a proposal of Kovačević et al [13] was based on the geolocation system, introducing zones and a two-layered, distance-aware system to accomplish strict QoS requirements. We do not assume such a sophisticated method, but base on the "application-layer ping, " which is very simple to implement.…”

Stringent QoS requirements of video streaming are not addressed by the delay characteristics of highly dynamic peer-to-peer (P2P) networks. To solve this problem, a novel locality-aware method for choosing optimal neighbors in live streaming multicast P2P overlays is presented in this paper. To create the appropriate multicast tree topology, a round-trip-time (RTT) value is used as a parameter distinguishing peers capabilities. The multicast tree construction is based on the Huffman source coding algorithm. First, a centrally managed version is presented, and then an effective use of a distributed paradigm is shown. Performance evaluation results prove that the proposed approach considerably improves the overlay efficiency from the viewpoint of end-users and content providers. Moreover, the proposed technique ensures a high level of resilience against gateway-link failures and adaptively reorganizes the overlay topology in case of dynamic, transient network fluctuations.

“…ISP-location awareness has attracted a lot of research mainly because of the huge costs inflicted by P2P traffic on ISPs. These costs are avoidable especially because of locality correlated users' searches, whose desired contents are located in the proximity [25,18,24]. ISP-location awareness in P2P systems will result in more locality of traffic.…”

Peer-to-peer (P2P) applications have recently attracted a large number of Internet users. Traditional P2P systems however, suffer from inefficiency due to lack of information from the underlay, i.e. the physical network. Although there is a plethora of research on underlay awareness, this aspect of P2P systems is still not clearly structured. In this paper, we provide a taxonomic survey that outlines the different steps for achieving underlay awareness. The main contribution of this paper is presenting a clear picture of what underlay awareness is and how it can be used to build next generation P2P systems. Impacts of underlay awareness and open research issues are also discussed.

“…Other studies have considered different applications such as [10] and [11]. Moreover, Gustavo Marfia et al [12] have conducted an experimental study on VideoOn-Demand system and they were concerned about the performance of the system on different environments such as campus and residential. Thus, they gave some results about protocol utilization and the start-up delay.…”

Peer-to-Peer (P2P) IPTV applications have increasingly been considered as a potential approach to online broadcasting. These overcome fundamental client-server issues and introduce new, selfmanagement features that help improving performance. Recently, many applications such as PPlive, PPStream, Sopcast, and Joost have been deployed to deliver live and Video-on-Demand streaming via P2P. However, the P2P approach has also shown some points of failure and limitations. In this paper we analyze, assess and compare two popular Live and Video-on-Demand P2P streaming applications, Sopcast and Joost. Our goal is not simply to underline similarities and differences from the architectural and functional point of view, but also to highlight their performance in terms of traffic behavior and network efficiency; thus our experiments have been conducted in different scenarios including a large-scale event (Euro 2008)..
