“…We assume an overlay composed of 1000 nodes and we re-compute the data loss when 40% of the nodes leave the network at different simulation periods. We consider the folowing periods: uniform (30,50), uniform (30,80), uniform (30,110), uniform (30,150) and uniform (30,180). Recall that we have a simulation time of 200 seconds.…”

The efficiency of live Peer-to-Peer (P2P) streaming protocols depends on the appropriateness and the management abilities of their underlying overlay multicast. While a tree overlay structure confines transmission delays efficiently by maintaining deterministic delivery paths, an overlay mesh structure provides adequate resiliency to peers dynamics and easy maintenance. On the other hand, content freshness, playback fluidity and streaming continuity are still challenging issues that require viable solutions. In this paper, we propose a Hybrid Live P2P Streaming Protocol (HLPSP) based on a hybrid overlay multicast that integrates the efficiency of both the tree and mesh structures. Extensive simulations using OMNET++ are conducted to investigate the efficiency of HLPSP in terms of relevant performance metrics, and position HLPSP with respect to DenaCast the enhanced version of the well-known CoolStreaming protocol. Simulation results show that HLPSP outperforms DenaCast in terms of startup delay, end-to-end delay, play-back delay and data loss.

“…In recent years, the issues of neighbour selection and overlay construction have been other challenges for researchers in designing P2P live video streaming systems. In mesh-based P2P streaming systems, a variety of neighbour selection techniques have been proposed for the construction and maintenance of overlays, which QoS-aware techniques such as [8,21,28] and location-aware techniques such as [29][30][31][32] are suitable for real-time applications such as live streaming.…”

“…In order to mitigate the coexistence problems existing between P2P applications and underlying network infrastructures some efforts have been made within the research community, some of them advocating for the need of collaborative mechanisms and layer cooperation schemes in this specific field [15]. The proposed collaborative approaches may assume diverse 1845-6421/03/8372 © 2015 CCIS perspectives, such as allowing network providers to explicitly provide valuable information to P2P applications [16] [19], the definition of inter-overlay coordination frameworks for better accommodating P2P traffic in the network [18], adding peering configuration flexibility and context-awareness to P2P level entities [11] [12] or even adopting optimized hierarchical overlays schemes for P2P traffic communications [17]. Within such context, this work intends to present a contribution to this area by proposing a collaborative P2P/ISP system able to sustain the development of novel TE mechanisms fostering the coexistence between P2P applications and ISP infrastructures.…”

Nowadays, many P2P applications proliferate in the Internet. The attractiveness of many of these systems relies on the collaborative approach used to exchange large resources without the dependence and associated constraints of centralized approaches where a single server is responsible to handle all the requests from the clients. As consequence, some P2P systems are also interesting and cost-effective approaches to be adopted by content providers and other Internet players. However, there areseveral coexistence problems between P2P applications and Internet Service Providers (ISPs) due to the unforeseeable behavior of P2P traffic aggregates in ISP infrastructures.In this context, this work proposes a collaborative P2P/ISPsystem able to underpin the development of novel Traffic Engineering (TE) mechanisms contributing for a better coexistence between P2P applications and ISPs. Using the devised system, two TE methods are described being able to estimate and control the impact of P2P traffic aggregates on the ISP network links. One of the TE methods allows that ISP administrators are able to foresee the expected impact that a given P2P swarm will have in the underlying network infrastructure. The other TE method enables the definition of ISP friendly P2P topologies, where specific network links are protected from P2P traffic. As result, the proposed system and associated mechanisms will contributefor improved ISP resource management tasks and to foster the deployment of innovative ISP-friendly systems.
