Description: JICQ是用JAVA语言编写的一个基于客户机/服务器(C/S)模式的局域短信实时通信工具系统，系统采用了Microsoft公司的SQL Server 2000作为后台数据库，系统通过JDBC访问数据库。系统分为服务器程序和客户程序两部分，服务器与客户间采用“传输控制协议”（TCP），通过套接字（Socket）连接，客户之间采用“用户数据报协议”（UDP），通过数据报套接字（DatagramSocket）建立连接。系统具有用户注册、用户登录、添加好友、删除好友、发送和接收消息等功能。-JICQ Java is a language based on the client / server (C / S) mode Local SMS real-time communications tool, the system uses Microsoft's SQL Server 2000 database as a background, system access to the database through JDBC. System is divided into server and two clients, the server-client "Transmission Control Protocol" (TCP), socket (Socket) connectivity, customers using the "User Datagram Protocol" (UDP), through Datagram Sockets (DatagramSocket) establish a connection. Users registered with the system, users log in, friends add, delete friends, send and receive news and other functions.

Description:
客户通过Socket(InetAddress,port)建立与服务器的连接。服务器与客户都通过构造BufferedReader,PrintWriter来建立输入输出流，然后双方通过该输入输出流来相互传递信息，一旦收到客户方的连接请求，服务器accept()方法返回一个新建的Socket对象。客户端然后向服务器发送消息，比如注册，登录，查找好友等，服务器收到来自客户的请求后，针对不同的消息处理请求, 虽然UDP不可靠但是对于icq可靠性并不太重要，而且UDP快速，所以客户间发送信息通过UDP。用户登录时通过类DatagramPacket和DatagramSocket创建UDP包括其本地接受端口以及发送端口，默认端口为5000和5001，通过取得的好友的IP地址来向好友发送消息（send(DatagramPacket)和接受消息(receive(DatagramPacket))。当用户通过UDP收到消息后，可以通过DatagramPacket的方法InetAddress getAddress()得到对方的ip地址，通过对好友列表比较以判断是谁并提示用户收到某某的消息，然后用户选择该用户查看消息，如果好友列表没有该人就显示收到陌生人的消息。用户可以按陌生人按钮查看消息。

Description: 编写客户/服务器程序，客户端Client.java使用DatagramSocket对象将数据包发送到服务器，请求获取服务器端的图像（考生可自选图像文件）。服务器端Server.java将图像文件包装成数据包，并使用DatagramSocket对象将该数据包发送到客户端。首先将服务器端的程序编译通过，并运行起来，等待客户的请求。-The preparation of client/server program, client Client.java use DatagramSocket object data packets sent to the server, requesting access to server-side image (Candidates may be optional graphics file). Server-side image file Server.java will be packaged into data packets, and use the DatagramSocket object to send the packet to the client. First, the procedure will be compiled by the server-side and up and running, waiting for client requests.

Description: UDP实现可靠数据传输。使用GBN算法，实现了：1.随即丢包(随机数产生器Math.random()) 2.丢包后遇冗余ack重传 3.超时重传 (DatagramSocket和Socket都有成员函数setSoTimeout(delay),通过捕获超时时抛出的IO异常来实现超时重传)-Reliable UDP data transfer. GBN algorithm used to realize: 1. Then packet loss (random number generator Math.random ()) 2. After the case of redundant packet loss retransmission ack 3. Retransmission timeout (DatagramSocket and Socket has a member function setSoTimeout ( delay), by capturing the IO exception thrown during timeout to achieve retransmission timeout)
