网络流量测量软件的设计与实现

I密级学士学位论文题目网络流量测量软件的设计与实现学院信息工程学院系计算机专业班级学号学生姓名指导教师起讫日期A1网络流量测量软件的设计与实现摘要为了方便网络编程，90年代初，由MICROSOFT联合了其他几家公司共同制定了一套WINDOWS下的网络编程接口，即WINDOWSSOCKETS规范，它不是一种网络协议,而是一套开放的、支持多种协议的WINDOWS下的网络编程接口。本篇论文主要是介绍了在TCP/IP基础上利用WINSOCK2对网卡进行编程，以达到网络流量监测的目的。论文首先介绍了TCP/IP协议，旨在介绍IP，TCP，UDP等比较重要的协议。主要是介绍IP头，TCP头，UDP头的特点，以便从IP头中可以获取源地址，目的地址，协议类型等信息。在随后的G4291G2059中G3476G1147了SOCKET的G1568G2737，SOCKETG3244G1949上G3476G1634了一G1617G3513信G1386口G3248G3406G4117G4090G4117SOCKET的G1386口的G1945G3384G1903G4365G1975G2719G1652G3757G1818G3513信，在本论文中主要G3338G2652了SOCKET的G2009G2379，监G3504G1764G1084G3783的G1718程。G2158G3480到程G3869G3244G3747中，对网卡G1889G4214G2662G3252的G3201G4386是G3513G1718G4176G3251套接G4499G271RG68WSOCKETG272G2303G3244G3747的。为了G3070G4176G3251套接G4499G2719接G3283G3406G4117的G3316G2156，G1838G3859要G3513G1718G2012SOCG46G66G53G36WG3201G4386G1102SIOG66G53CG57G36G47G47。对G3316G2156G871的获取G3513G1718RECG89G11G12G1734G3316G2303G3579G1102。G4523后要G3579G1102的G1629G4532G2140是对G3406G989获的IPG3316G2156G871进行G1491G3685以G3476取G1147G3649G2604G3406G3859要的信息。在论文的G4523后是旨在G3338G2652进一G996G1629G4532的G4282开。G1681G1999G4499G289TCP/IP，WINSOCK，G4176G3251套接G4499，NETG37IOSA2ABSTRACTFORCONVENIENCEOFNETWORKPROGRAMMING,INTHEEARLY1990S,ANEWSETOFNETWORKPROGRAMMINGINTERFACEUSINGUNDERWINDOWSWASESTABLISHEDBYSOMECOMPANIESUNITEDBYMICROSOFTITISKNOWNASWINDOWSSOCKETNORMITISNTAKINDOFNETWORKPROTOCOL,BUTANOPENNETWORKPROGRAMMINGINTERFACESUPPORTMULTIPLEPROTOCOLSUNDERWINDOWSTHEMAINPURPOSEOFTHETHESISISTOINTRODUCEHOWTOUSEWINSOCK2PROGRAMONNETWORKADAPTERUNDERTHEPROTOCOLOFTCP/IPTHISISFORTHEPURPOSEOFMEASURETHENETWORKDISCHARGEATTHEBEGINNINGOFTHETHESIS,WEINTRODUCEALLIMPORTANTPROTOCOLSOFTCP/IP,LIKEIP,TCP,ANDUDPWEINTRODUCEIPHEADER,TCPHEADERANDUDPHEADERFORTHEMOSTIMPORTANTBECAUSEWENEEDACQUIRETHEINFORMATIONOFSOURCEADDRESS,DESTINATIONADDRESS,ANDPROTOCOLTYPEFROMTHEIPHEADERINTHEFOLLOWINGSECTION,WEGIVETHECONCEPTOFSOCKETSOCKETSACTUALLYPROVIDEACOMMUNICATIONPORTTOALLOWALLTHECOMPUTERSTHATHAVESOCKETPORTTOCOMMUNICATEWITHEACHOTHERINTHETHESIS,WETALKONTHEPROCESSOFTHESOCKETSBUILDINGLISTENINGANDCANCELINGINTHEPROGRAM,WEUSERAWSOCKETTOSETADAPTERONTHEMIXEDMODETOLETTHESOCKETRECEIVEALLDATA,WEALSONEEDTOSETTHEONSIO_RCVALLTHENWEUSETHEFUNCTIONRECVTOGETDATAPACKATLASTWENEEDANALYZETHEDATAPACKTOGETTHEINFORMATIONWENEEDKEYWORDSTCP/IP,WINSOCK，RAWSOCKET,NETBIOSA3目录摘要1ABSTRACT2前言4第一章绪论511TCP/IP协议及其协议分析方法5111分层5112IP地址6113端口6114TCP/IP协议在WINDOWS中的实现712WINSOCK编程713网络流量测量的程序实现原理8第二章TCP/IP协议集921TCP/IP协议简介922IP协议923TCP协议10231TCP服务模型10232TCP数据段头11233TCP协议的建立1224UDP协议13第三章WINSOCK编程概述1431套接字的概念1432套接字的种类1433套接字的建立14第四章网络流量测量的程序实现1641网卡初始化16411NETBIOS概述16412利用NETBIOS来初始化网卡1642原始套接字的设置1643IP包的协议分析1744结果与测试19结论21结束语22参考文献23A4前言A0A5A6A7A8A9A10A11A12A13A14A15A16A17A18A19A20A21A22A23A24A25A22A24A23A17A26A27A28A29A20A9A10A30A31A32A33A34A35A36A37A38A39A40A41A42A17A43A44A45A46A47A48A20A9A10A34A35A49A50A51A32A17A42A52A53A54A55A56A57A58A17A59A60A45A31A38A20A61A62A61A63A17A64A65A0A66A67A42A20A68A32A33A69A70A71A72A73A74A20A75A76A17A77A78A9A10A20A56A79A9A10A47A80A81A17A82A83A9A10A45A84A85A86A87A38A88A89A90A91A92A9A10A53A93A94A95A83A17A11A12A96A96A97A98A99A100A101A102A103A104A105A106A107A108A109A101A110A111A112A113A114A115A116A117A118A119A120A106A107A121A122A123A124A125A126A124A127A128A116A129A130A131A116A132A133A97A98A134A135A136A137A122A123A124A125A126A124A127A128A138A139A140A141A101A142A143A116A122A123A124A125A126A124A127A128A144A145A146A147A148A101A149A150A151A116A145A146A101A152A153A154A155A114A156A157A158A121A159A160A161A162A101A163A164A104A122A123A124A125A126A124A165A166A167A168A169A170A171A172A173A174A175A176A177A178A101A179A180A181A182A183A184A97A98A185A186A187A188A116A189A113A105A190A169A170A171A191A192A193A194A195A149A150A151A114A156A196A197A198A199A101A182A97A200A201A104A202A203A179A180A204A205A101A206A207A154A155A116A208A195A127A128A182A209A101A210A211A212A213A214A215A112A113A129A130A145A199A216A217A218A216A219A220A101A217A221A129A130A222A206A223A224A189A104A105A225A226A97A98A99A100A101A103A100A114A115A116A227A228A119A120A229A230A231A223A151A101A162A232A138A179A180A121A233A104A234A235A162A232A101A236A237A203A161A238A239A240A241A242A243A244A245A246A247A194A101A104A239A240A241A242A243A244A245A248A199A213A97A98A249A250A251A239A123A252A246A247A194A227A228A253A229A202A254A247A194A101A230A97A255A101A204A0A1A2A153A104A161A238A19A3A242A210A3A244A4A4A5A19A6A246A192A197A7A8A247A194A230A97A255A101A152A153A104A161A238A192A136A239A123A252A192A239A9A10A7A8A236A237A97A255A101A189A188A11A12A180A97A255A101A13A14A15A148A227A230A27A210A101A97A255A192A136A179A180A239A123A252A16A192A17A192A122A7A8A116A130A44A225A226A204A0A1A227A231A139A116A129A130A192A136A239A123A252A18A17A122A18A122A7A8A130A236A237A97A255A101A162A232A104A234A187A116A227A228A129A130A185A197A97A255A101A10A18A123A223A56A130A44A225A226A225A179A20A101A2A153A104A229A112A113A97A98A99A100A101A103A100A116A236A243A19A245A244A3A21A144A227A228A157A158A121A179A180A231A123A116A227A228A161A238A234A180A231A123A129A130A112A113A230A126A124A239A130A22A101A239A101A189A23A24A101A102A103A104A227A228A161A238A30A25A26A0A28A2
