Structured Peer-to-Peer Network and Application-layer Multicast 结构化P2P网络与应用层组播
On the basis of analysis of the problems of multimedia communication synchronization, this paper proposes a new synchronous method of multimedia communication which is controlled cooperatively by source node and destination node, achieved hierarchically and synchronized correspondingly at the peer layer. 本文在分析多媒体通信同步问题的基础上,提出了一种由源结点和目标结点协同控制、分层实现、同层之间对应同步的多媒体通信同步方法。
This architecture consists of a peering layer that runs between the application and transport layers on each client peer. The peering layers at different nodes coordinate among themselves to establish and maintain a multicast tree. 在该结构中,每个客户peer端在应用层与传输层之间加入peering层,实现结点之间的协调和建立、维护组播树。
Results show that: Students with good peer relationship have multi-layers of relation network, of which the function of interaction differs in each layer. 个案分析发现:同伴关系较好学生的关系网层次较丰富,且各关系层次的交往功能各不相同。
The three layer construction of the system includes the source server layer, the proxy server layer and the client peer layer. 系统的三层结构包括:源服务器层、代理服务器层和用户层。
It is constituted of terminal, switch, router and the information exchanging from those nodes, setup from bottom to top. The information exchange between high layer and low layer is across peer group leader in each layer. 它是一种树形分层结构,由网络节点,即终端、向量交换机、向量路由器相互交换节点和链路信息,自下而上构建形成,上下层之间的信息通过每层对等组组长传递。
Structured peer to peer networks are service discovery models that utilize pure distributed routing mechanisms and discovery the services by key, and there are a lot of applications built on them, for example, distributed storage systems, application layer multicast systems and file sharing systems. 结构化对等网络是一种采用纯分布式的消息传递机制和根据关键字进行查找的定位服务模型,目前在分布式存储、应用层多播、文件共享等领域已经得到广泛应用。
