網(wǎng)絡流量測量軟件的設計與實現(xiàn)

摘 要：為了方便網(wǎng)絡編程，90年代初，由Microsoft聯(lián)合了其他幾家公司共同制定了一套WINDOWS下的網(wǎng)絡編程接口，即Windows Sockets規(guī)范，它不是一種網(wǎng)絡協(xié)議,而是一套開放的、支持多種協(xié)議的Windows下的網(wǎng)絡編程接口。本篇論文主要是介紹了在TCP/IP基礎上利用winsock2對網(wǎng)卡進行編程，以達到網(wǎng)絡流量監(jiān)測的目的。論文首先介紹了TCP/IP協(xié)議，旨在介紹IP，TCP，UDP等比較重要的協(xié)議。主要是介紹IP頭，TCP頭，UDP頭的特點，以便從IP頭中可以獲取源地址，目的地址，協(xié)議類型等信息。在隨后的章節(jié)中提出了Socket的概念，Socket實際上提供了一個通信端口使所有擁有Socket的端口的計算機之間能夠相互通信，在本論文中主要說明了socket的建立，監(jiān)聽和撤銷的過程。具體到程序實現(xiàn)中，對網(wǎng)卡混雜模式的設置是通過原始套接字（raw socket）來實現(xiàn)的。為了讓原始套接字能接受所有的數(shù)據(jù)，還需要通過將SOCK_RAW設置成SIO_RCVALL。對數(shù)據(jù)包的獲取通過recv()函數(shù)來完成。最后要完成的工作就是對所捕獲的IP數(shù)據(jù)包進行分析以提取出我們所需要的信息。在論文的最后是旨在說明進一步工作的展開。
關鍵字： TCP/IP，Winsock，原始套接字，NetBios

Abstract: For convenience of network programming, in the early 1990s, a new set of network programming interface using under WINDOWS was established by some companies united by Microsoft. It is known as Windows Socket Norm. It isn't a kind of network protocol, but an open network programming interface support multiple protocols under WINDOWS. The main purpose of the thesis is to introduce how to use Winsock2 program on network adapter under the protocol of TCP/IP. This is for the purpose of measure the network discharge. At the beginning of the thesis, we introduce all important protocols of TCP/IP, like IP, TCP, and UDP. We introduce IP header, TCP header and UDP header for the most important because we need acquire the information of source address, destination address, and protocol type from the IP header.
In the following section, we give the concept of Socket. Sockets actually provide a communication port to allow all the computers that have Socket port to communicate with each other. In the thesis, we talk on the process of the Socket’s building listening and canceling. In the program, we use RAW Socket to set adapter on the mixed mode. To let the Socket receive all data, we also need to set the on SIO_RCVALL. Then we use the function recv () to get data pack. At last we need analyze the data pack to get the information we need.
