Summary Nowadays, peer‐to‐peer network plays a significant role in data transfer and communication. The past few years have witnessed considerable growth in this area because of its inherent advantages. Peer‐to‐peer live streaming has a significant impact on video transmission over the Internet. Major factors that influence the performance of P2P live streaming are overlay construction and scheduling strategies. Although, a large number of scheduling schemes are developed but none of them is comprehensive enough to provide solutions to live streaming issues. These suffer from substantial delay and low video quality at the receiver side. In this paper, a new start‐up–based selection procedure and slack time–based scheduling scheme is proposed. The start‐up selection procedure defines the start‐up buffer location for new peer, and the scheduling scheme selects both the chunk and peers. The proposed scheduling scheme uses both push and pull priority–based strategies. The simulation results of the proposed approach demonstrates significant improvement in both the network performance and video quality at the receiver side. It is observed that playback delay, startup delay, and end‐to‐end delay in the network are reduced and quality of the video at receiver side is improved as the distortion and frame loss ratio is decreased.

“…Transmission of scalable coded video is preferred by several systems since there is advantage of encoding the video data into multiple rates and of providing quality adaptation. For sending layered video, different approaches are proposed about assigning priority to the chunks according to the layer information of the carried video data, [8,17,30,33]. As stated in [8], disseminating layered video content in mesh based P2P video streaming systems requires developing packet scheduling mechanisms that take dependencies of video layers into account.…”

In this paper, we propose a new multicast tree framework to be used in peer-to-peer (P2P) live video streaming systems. The proposed system, adapts the tree links under high peer churn and runs in a totally distributed manner. In order to provide this dynamism and seamless streaming at the same time, we propose a cross layer design involving scalable video codec, backup parents and hierarchical clusters. The performance of the system is measured in real world environment PlanetLab that has nodes distributed all over the world. The experiments show that the proposed system provides high quality of experience (QoE) in terms of Peak Signal to Noise Ratio (PSNR), playback delay and duration of pauses. The proposed system also provides incentive mechanism to its users.

“…Other relevant related works such as the work by Bradai et al [2] or Medjiah et al [7] do investigate quality adaptation in a live streaming scenario, but do so using meshpull based systems. However, live streaming over mesh-pull based systems causes performance degradation, as the topology cannot account for the fast delivery of new content [18], [16].…”

“…However, live streaming over mesh-pull based systems causes performance degradation, as the topology cannot account for the fast delivery of new content [18], [16]. Moreover, the work of Bradai et al [2] focuses at keeping the numbers of video layer changes low and the amplitudes of adaptations small, following the observations by Zink et al [20]. While this work addresses an important problem for SVC-based quality adaptations, it does not address the requirements of state-of-the-art hybrid streaming systems.…”

Live streaming of large-scale events such as the Olympic Games with a huge number of viewers is challenging, as the streaming infrastructure needs to scale fast and big, and often in an unpredictable manner. Peer-to-peer (P2P) live streaming (Peercasting) has proven to be beneficial in these scenarios, as resources are scaling inherently with the number of nodes. However, churn behavior in a node's neighborhood may result in fluctuating downstream bandwidth and thus freezing (stalling) playback. Related work tries to mitigate this effect by using layered video codecs, focusing on single-dimensional scalability in mesh-pull based systems. Yet, the benefits of multidimensional scalability (resolution, frame rate, and quantization) combined with coexisting pull-/push mechanisms introduced by modern hybrid P2P streaming architectures have not been studied in detail. Consequently, this work proposes a new scheduling algorithm taking these aspects into account. The evaluation shows large benefits for end-users by reducing the frequency of stalls by 90% even under extreme conditions.
