While there are several ways for video finding in UGC (user generated content) video systems, video search is still the number one source of video views in aggregation. In this paper, we propose to use peer-assisted search to alleviate the server burden caused by video search.To this end, we have measured and analyzed YouKu, the largest UGC video system in China. With a large dataset, we have found non-power law distribution of video popularity, low replication level for popular videos, skewed user activity and interest locality. Based on the findings, we design two-layer hierarchical semantic overlay structures to implement peer-assisted search for UGC video systems. A novel search algorithm called WISE is proposed to guide queries quickly to the semantically relevant clusters by visiting a very small fraction of nodes. Simulations using the YouKu trace demonstrate that WISE is effective and helpful to assist the search in UGC video systems. To the best of our knowledge, this is the first work to study peer-assisted search in UGC.

“…In order to improve the performance of P2P live streaming systems, a number of avenues have been explored: using incentive mechanisms to encourage more contribution of peers [7], [8], applying network coding to segment scheduling [9] and sharing user generated contents [10]. More recently, there is some work focusing on resource allocation [11] and interchannel cooperation in multi-channel scenarios [12].…”

Small playback lag in live streaming is important for time-critical and interactive applications such as live stock, market updates, sports and remote education. In this paper, we present Elite addresses the playback lag problem in peer-assisted live streaming systems. Instead of deploying a large initial offset to all the users, Elite seeks the possibility of initializing users with layered proportional initial scheduling point, thus achieving differentiated playback lag service for the system. For saving server bandwidth and reducing lag time, Elite employs a novel strategy which arranges peers into a virtual tree structure and quantifies playback lag of each layer that finally converges to a constant value. This way, Elite can help users to achieve much shorter average playback lag and prioritized service within the same channel. As illustrated in our design, analysis, and simulation studies, Elite is able to fully exploit limited pool of server bandwidth to support peer-assisted live streaming with prioritized playback lag, and achieves shorter average playback lag compared with synchronized strategy, such as R 2 .

Cloud computing is a new technology that delivers services to end users on the promise of supporting ondemand in a flexible manner by scheduling bandwidth, storage and compute resources on the fly. Content delivery networks (CDN) based computers are considered as the best solutions to deliver User-generated content (UGC). But none of the existing CDN based solutions can support all the required features in UGC delivery. In this paper we analyses the various mechanism for deploying video in geographically distributed data center and optimal utilization of bandwidth, storage and other computing resources. Optimal Deployment can be done by using Dominating Set Algorithm.
