A Telco-CDN can be regarded as an intra-domain overlay network with tight resources and critical deployment constraints. This paper addresses two problems in this context: (1) the construction of the overlays used to deliver the video channels from the entrypoints of the Telco-CDN to the appropriate edge servers; and (2) the allocation of the required resources to these overlays. Our ultimate goal is to maximize the number of delivered channels while preserving network resources. Two classes of heuristic algorithms, namely two-step optimization and joint-optimization, are proposed to solve these problems. The conducted evaluations confirm the efficiency of the jointoptimization approach.

“…Some examples are rstream [46] which uses fountain code technique [47], and the systems proposed in [48,49]. Recently, the authors of [50] have presented a scalable video streaming system based on end-system multicast, where the scalable network coding technique with pushbased content distribution is extended to perform prioritized streaming with error and congestion control.…”

Abstract. Peer-to-Peer based Video-on-Demand (P2P-VoD) applications are becoming very popular for scalable video distribution in both academic and commercial environments. Asynchronous arrival of peers who wish to watch videos from beginning, as well as willing to avail interactive services like jump, rewind, fast-forward etc. in these systems makes it challenging to design and deploy them. A lot of research has already been done on the architectural design issues of P2P-VoD systems. In this paper, we present a survey on approaches which address some existing design issues like alleviating the server stress due to asynchrony, building efficient P2P-VoD applications with interactive services and handling peer churn as well as the time-varying nature of network. In addition to these issues, we also discuss the challenges in deployment of P2P-based VoD systems with additional user experience features like on-demand watching of segmented scenes, on-the-fly creation of playlists etc. over best-effort Internet.

Abstract-The delivery of live video channels for services such as twitch.tv leverages the so-called Telco-CDN-Content Delivery Network (CDN) deployed within the Internet Service Provider (ISP) domain. A Telco-CDN can be regarded as an intra-domain overlay network with tight resources and critical deployment constraints. This paper addresses two problems in this context: (1) the construction of the overlays used to deliver the video channels from the entrypoints of the Telco-CDN to the appropriate edge servers; and (2) the allocation of the required resources to these overlays. Since bandwidth is critical for entrypoints and edge servers, our ultimate goal is to deliver as many video channels as possible while minimizing the total bandwidth consumption. To achieve this goal, we propose two approaches: a two-step optimization where the optimal overlays are firstly computed, then an optimal resource allocation based on these pre-computed overlays is performed; and a joint optimization where both optimization problems are simultaneously solved. We also devise fast heuristic algorithms for each of these approaches. The conducted evaluations of these two approaches and algorithms provide useful insights into the management of critical Telco-CDN infrastructures.
