Term project title 学期设计标题
Peer-to-peer storage emulation
对等网络存储
Motivations 动机
Based on Sever/Client model net communication is a centralized mode. The resource cannot use sufficiently. Sever is the bottleneck of the whole network. Once sever gets mistakes, the whole network cannot work.
基于服务器/客户端模式网络通信是一种中央集权式的模式，资源不能充分的利用，服务器是整个网络的瓶颈，一旦服务器有错误产生，整个网络就会瘫痪。
Peer-to-peer is a communications model in which each party has the same capabilities and either party can initiate a communication session. Other models with which it might be contrasted include the client/server model and the master/slave model。the center of P2P network is the each PC not the sever. We can use the spare storage rooms in whole network, then implement P2P storage, thereby reduce network storage coast.
对等网络是每部分有一样的能力并且每部分都可以发起一个信息通讯会议的通信模式。这种模式与其他的包括服务器/客户端模式和主/副模式形成对比，p2p网络的核心是每一台pc都不是服务器，我们在整个网络里可以用少量的存储空间，要实现p2p存储，
On the Internet, peer-to-peer is a type of transient Internet network that allows a group of computer users with the same networking program to connect with each other and directly access files from one another's hard drives。
在internet网络中，对等网是一种短暂的internet网络类型，他允许一个组的计算机用户用同一个网络程序来连接其他人，并且直接的从其他人的硬盘上访问存储文件
Goals 目的
Users can share net-resources, deal with data (i.g.file) on end, connect other’s PC directly download without connect to server. Server record renew log.
用户可以共享网络资源，连续的处理数据（或者文件），不用连接服务器就可以连接其他人的电脑直接下载，服务器纪录更新日志。
Scope of the project
Peer computing; Co-work; Search engine; Content share. 对等计算，共同工作，搜索引擎，内容共享
Related to Peer- to –peer routing algorithms, distributed index and searches problem, distributed security system problem and resource accessing efficiency problem.设计到点对点路由运算法则，分布式的索引和搜索功能，分布式安全系统问题，资源访问效率问题。
Expected outcomes预期结果
block-storage, redundancy storage, metadata management, node P event management.
As a client: Require data→ Search data→ download data→ modification data→ Save and update data
作为客户端：发出要求数据资料----搜索数据----下载数据----修正数据—保存更新数据
As a server: Answer a require→ Upload data→ get the renew record
作为服务端：回答要求----上载数据---
Computing and network environments 计算机网络环境
Java, Unix or Linux java Unix或者Linux
