一个p2p流媒体系统必须能够利用节点之间的位置信息，以提供一个流快速到所有的节点具有高水平的带宽利用率。在本文中，我们提出了一个局部感知和平衡覆盖的p2p流媒体直播，它可以适应参与节点和底层网络的动态行为。我们的覆盖创建和维护通过使用两种算法，称为放置和交换算法，我们认为在本文中的主要贡献。这些负责节点的插入以及覆盖的动态和分布式优化，以反映底层网络。建议的覆盖评估，通过广泛的模拟表明，通过本地化的同行的带宽利用率和设置时间显着改善。
A p2p streaming system must be able to exploit the locality information between peers, in order to deliver a stream quickly to all peers with high level of bandwidth utilization. In this paper we propose a locality aware and balanced overlay for p2p live streaming which can adapt to the dynamic behavior of the participating peers and the underlying network. Our overlay is created and maintained through the use of two algorithms, called the placement and the swapping algorithm that we consider as the major contributions in this paper. These are responsible for the insertion of a node and the dynamic and distributed optimization of the overlay in order to reflect the underlying network. The proposed overlay is evaluated through extensive simulations that show that the bandwidth utilization of the peers and the set-up time are significantly improved through locality between peers.
