TCP/IP is transmission control protocol/Internet Interconnection agreement, has another name called network communication protocol, is the basis of the most basic agreement of Internet, Internet Internet, the IP agreement of network layer and the Transmission Control Protocol of transport layer, consists of.TCP/IP has defined electronic equipment and how to be connected into the Internet, and the standard how to transmit between them of data.Agreement has adopted the hierarchical structure of 4 layers, and the network that every one deck is all called out its lower one deck to be provided completes the demand of oneself.Popular: TCP is responsible for finding the problem of transmission, once there being problem to send signal, requires transmission again, until all data securities correctly are transferred to destination.And IP is each address of computer regulation to the Internet.ICP/IP protocol is not being collectively referred to as of TCP and these two agreements of IP, and refers to the whole TCP/IP protocol suite in the Internet.From protocol hierarchy model aspect, TCP/IP is comprised of four levels: network interface layer, network layer, transport layer, application layer.ICP/IP protocol not in full conformity with the seven layer reference model of OSI, OSI(Open System Interconnect) be traditional Open System Interconnection Reference Model, be a kind of 7 layers of abstract reference model of communication protocol, wherein every one deck is carried out a certain particular task.The purpose of this model is to make the intercommunication mutually on identical level of various hardware.These 7 layers are: Physical layer, data link layer (network interface layer), network layer (network layer), transport layer (transport layer), session layer, presentation layer and application layer (application layer).And the TCP/IP communications protocol has adopted the hierarchical structure of 4 layers, the network that every one deck is all called out its lower one deck to be provided completes the demand of oneself.What focus on due to the deviser of Advanced Research Projects Agency Network is the network interconnection, allows communication subnet (network interface layer) to adopt variety of protocol existing or that have in the future, so special agreement is not provided in this level.In fact, ICP/IP protocol can be connected on any network by network interface layer, for example X.25 switching network or IEEE802 LAN (Local Area Network).Physical layer is the various characteristics that defines physical medium: 1, mechanical property; 2, characteristic electron; 3, functional characteristic; 4, rules characteristic.Data link layer is to be responsible for receiving the IP packet and sending by network, or receives physical frame from network, extracts the IP packet out, gives the IP layer.Common interface layer agreement has: Ethernet802.3, Token Ring802.5, X.25, Frame relay, HDLC, PPP ATM etc.Network layer is responsible for the communication between adjacent computers.Its function comprises three aspects:.Processing sends request from the grouping of transport layer, after receiving request, will divide and be assembled into IP datagram, fills header, selects to go to the path of stay of two nights machine, then datagram is mail to suitable network interface.Process the input datagram: at first check its legitimacy, if then sought footpath--this datagram has arrived stay of two nights machine, removes header, by remaining part, gives suitable host-host protocol; If this datagram not yet arrives the stay of two nights, forward this datagram.Process path, Flow Control, the problem such as congested.Network layer comprises: IP (Internet Protocol) agreement, ICMP (Internet Control Message Protocol) Internet Control Message Protocol, ARP (Address Resolution Protocol) AARP, RARP (Reverse ARP) reverse address resolution protocol.IP is the core of network layer, by Route Selection, will after next IP encapsulation, give interface layer.IP datagram is Connectionless transport service.ICMP is supplementing of network layer, can the loopback message.Whether be used for Sampling network unobstructed.The Ping order is exactly to send the echo of ICMP bag, and the echo relay by loopback carries out network test.ARP is the forward address resolution protocol, by known IP, finds the MAC Address of respective hosts.RARP is RARP, by MAC Address, determines the IP address.Such as non-disk workstation also has the DHCP service.Transport layer provides the communication between application program.Its function comprises: one, formatted message stream; Two, provide transmitting.For realizing the latter, transport layer protocol regulation receiving end must be beamed back confirmation, and if packet loss, must resend, " three-way handshake " process that what's frequently heard can be repeated in detail, thus reliable data transmission is provided.Transport layer protocol is mainly: transmission control protocol TCP (Transmission Control Protocol) and User Datagram Protoco (UDP) UDP (User Datagram protocol).Application layer provides one group of application program commonly used to the user, such as Email, file transfer access, Telnet etc.Telnet TELNET is used the TELNET agreement to be provided at the interface of registering on the network others main frame.The TELNET session provides the virtual terminal based on character.The file transfer access FTP provide the function of the file copy between the network inner machine with File Transfer Protocol.Application layer protocol mainly comprises several as follows: FTP, TELNET, DNS, SMTP, NFS, HTTP.FTP (File Transfer Protocol) is file transfer protocol (FTP), generally uploads and downloads the service with FTP, and FPDP is 20H, and control port is 21H.The Telnet service is user's remote login service, uses the 23H port, uses plain code to transmit, and confidentiality is poor, simple and convenient.DNS (Domain Name Service) is the domain name mapping service, provides domain name to arrive the conversion between the IP address, uses port 53.SMTP (Simple Mail Transfer Protocol) is Simple Mail Transfer protocol, is used for controlling transmission, the transfer of mail, uses port 25.NFS(Network File System) be network file system(NFS), for the file-sharing between the different main frames of network.HTTP (Hypertext Transfer Protocol) is HTML (Hypertext Markup Language), for realizing the WWW service of internet, uses port 80.
The invention has the beneficial effects as follows the intelligent management that can better utilize more efficiently 4G communication module, RFID module, WIFI module, picture recognition module to realize the BRT rapid transit, the WIFI focus is provided to passenger inside the vehicle's the portable electronics such as mobile phone, panel computer simultaneously.
