Finally , every layer of this tcp / ip protocols stack and protocols being used such as arp , ip , icmp , udp are analyzed deeply and in detail , and flow charts of such protocols and software design ideas are proposed 再针对tcp / ip协议栈各个层次所用到的协议: arp , ip , icmp , udp进行深入细致的分析,并分别给出各个协议的工作流程图和相应的软件设计思想。
The new method firstly put forward by this paper : the method of preventing ip embezzlement based arp spoofing , is low cost and easy to implement , and also , it ' s effectual to various kind of ip embezzlement 本文独立提出的ip地址防盗用新方法即基于arp伪装技术的ip地址防盗用解决方案，具有低成本、易实施的特点，而且对各种ip地址盗用的形式都能够防范。
In link layer , the procedure of data transmission between the chief chip and interface chip is described at large . at the same time , the operational principle of arp is exposed very clear and the flow diagram for implement is provided thoroughly 在链路层，详细描述了主控芯片和接口芯片的数据传输过程，同时对arp的工作过程原理透彻的介绍并给出了翔实的实现流程图。
In the data communication design , the paper illurstrates the implementation of the communication between internal network and external network , including the implementation of arp , network address translation , ip data collection , user authentication and packets filtering 数据通信模块的设计中，详细介绍了内部网与外部网数据通信的实现，包括地址解析协议的实现、网络地址转换、流量数据采集、用户认证及数据包的过滤。
The fourthly part of this paper introduces hardware circuit of embedded web server , analyses some standard internet protocols like ethernet 、 arp 、 ip 、 icmp 、 udp 、 and tcp , describe the hypertext transport protocols http in detail and realize a embedded web servers at same time 第四部分介绍嵌入式web服务器的硬件电路,分析了internet协议标准中的以太网、 arp 、 ip 、 icmp 、 udp和tcp协议,详细的描述了超文本传输协议http ,实现了嵌入式web服务器。
The latter ptda discusses the related theorems and rules ofjudgeing the root bridge and root port as well as specifing the bridge and port , makes use of many protocols such as stp , snmp and arp , eventually determines the conjunction relation between router , switches and host in the network 该算法讨论了确定根网桥、根端口、指定网桥和指定端口的相关规则和定理,正确运用了stp 、 snmp 、 arp等协议,成功地确定了网络中路由器、交换机和主机之间的连接关系。
Ieee802 . 11b can support high digital rate and provide good access service . the devices that support ieee82 . 11b is more and more prevalent . so we adopt it as our mac protocol . this paper is mainly to research how wr can provide access service and control the unauthenticated users to access the network . we choose the operation mode of the nic and use visual router and arp to resolve the problems 本文针对在链路层采用ieee802 . 11b协议以后，结合移动用户要在多个无线路由器间切换，研究了无线路由器提供接入需要解决的问题，通过接入网卡的设置，虚拟路由器、 arp代理和目的mac地址的处理等解决了对移动用户全网漫游的支持。
On the basis , firstly , the technically - promising method of solving ip embezzlement : the method of preventing ip embezzlment based on snmp has been expatiated ; and then , a new method of preventing ip embezzlement : the method of preventing ip embezzlement based arp spoofing has been brought forward ; lastly , the key technic of preventing ip embezzlement : packet capturing has been studied , and a shortcut to implement packet capturing in windows platform : the method of packet capturing based on winpcap has been found 在此基础上，首先对比较有技术发展前景的ip地址防盗用方案?基于snmp的ip地址防盗用方案，进行了详细的分析、论述。然后，提出了一种新型的ip地址防盗用解决方案?基于arp伪装技术的ip地址防盗用方案。最后，本文对解决ip地址盗用问题的关键技术?网络捕包技术，进行了分析、研究，并提出一个在windows平台下实现网络捕包的快捷方法?基于winpcap的网络捕包技术。
