摘要
针对现有P2P网络依赖中心服务器、对等网络建立困难、网络流量过大、需要大量的无效流量等问题,提出了一种对等网络体系结构实现方法。该方法建立在TCP/IP协议之上,所有的抽象实体均拥有一个DDNS域名或DNS域名;当这些实体一旦连上网络,就可以通过其域名对其进行访问,组成无层次结构的逻辑对等网络;实体之间的地位完全平等;每个实体既作为向其它实体提供服务的服务器,又作为使用其它实体所提供服务的客户端;各节点存储其他节点的内容分类信息,采用分级内容查询方式。
The paper proposes a kind of P2P network realization method, in order that the problems about P2E such as central server dependency, network establishment difficulty, large network traffic, large ineffective traffic, are solved. Based on TCP/IE every entity involved has a DDNS domain name or DNS domain name. When these entities connect to Internet/Intranet, they can be accessed by domain name and construct a non-hierarchical P2P network. Each entity is completely equal and can serve as server or client simultaneously. Each entity stores content classification information of other entities, and contents are queried hierarchically.
