Description
Technical Field
The invention relates to the technical field of computer networks and distributed server systems, in particular to a network diagnosis system and a network diagnosis method compatible with various network diagnosis protocols and supporting multi-terminal diagnosis.
Background
The international organization for standardization (ISO) has established the OSI model, OSI open systems interconnection, SI is an open communication systems interconnection reference model that defines standards for the interconnection of different computers and is the basic framework for designing and describing computer network communications. The OSI model divides the network communication into 7 layers, from bottom to top, a physical layer, a data link layer, a network layer, a transport layer, a session layer, a presentation layer and an application layer, each of which may have several sublayers. The application layer, the presentation layer, the session layer and the transmission layer of the upper layer respectively define the functions of the application program, and the lower layer 3 of the network layer, the data link layer and the physical layer mainly face to-end data flow passing through the network. The application layer is an application communicating with other computers, and is a communication service corresponding to an application program. For example, a word processor without communication capability cannot execute the code of communication, nor is the programmer working on word processing concerned about OSI layer 7. However, if an option to transfer files is added, then the programmer of the word processor needs to implement layer 7 of OSI. Example (c): TELNET, HTTP, FTP, NFS, SMTP, and the like. Presentation layer: the main functions of this layer are to define the data format and encryption. For example, FTP allows you to choose to transmit in binary or ASCII format. If binary is selected, the sender and receiver do not change the content of the file. If the ASCII format is selected, the sender will convert the text from the sender's character set to standard ASCII before sending the data. The standard ASCII is converted at the receiver to the character set of the receiver computer. Example (c): encryption, ASCII, etc.; and a session layer: it defines how to start, control and end a session, including the control and management of multiple two-way messages, so that an application can be notified when only a portion of a successive message is completed, so that the data seen by the presentation layer is continuous, and in some cases, if all the data is received by the presentation layer, the presentation layer is represented by the data. Example (c): RPC, SQL, etc.; a transmission layer: the functions of this layer include whether to select an error recovery protocol or a non-error recovery protocol, and multiplexing the input of data streams for different applications on the same host, and reordering the received packets out of order. Example (c): TCP, UDP, SPX; network layer: this layer defines end-to-end packet transport, which defines logical addresses that can identify all nodes, and also defines the way in which routing is implemented and the way in which it learns. The network layer also defines a fragmentation method how to break a packet into smaller packets in order to accommodate transmission media having a maximum transmission unit length smaller than the packet length. Example (c): IP, IPX, etc.; data link layer: which defines how data is transmitted over a single link. These protocols are related to the various media in question. Example (c): ATM, FDDI, and the like; physical layer: the OSI physical layer specifications are related to the transmission medium and these specifications are also commonly referred to standards established by other organizations. Connectors, frames, frame usage, current, coding, and optical modulation are all within the context of various physical layer specifications. The physical layer often accomplishes the definition of all the details with multiple specifications. Example (c): rj45, 802.3, etc.
The existing common network faults are physical faults, logic faults, network protocol faults and internet environment faults. The physical faults refer to equipment line damage, plug looseness, serious electromagnetic interference on the line, network card equipment faults and the like; the logic failure refers to network configuration error and the like; the network protocol failure means that the network protocol is in an installation or configuration error, the IP or port of the protocol is incorrect, the content of the protocol message is not supported or identified, and the like; the internet environment faults refer to the problems that the packet loss rate is increased and the data transmission speed is slowed due to network congestion, and the network of an accessed server is broken down due to DDOS attack.
