interface to write programs at different layers connected to it. It can be said that both the network protocol layer and the network interface driver can regard MUX as an application procedure interface (API ). Adding a network interface device driver to the VxWorks target system is as simple as writing an application

Last time, we introduced the BOOTP protocol for the diskless workstation to automatically obtain the IP address, the TFTP protocol for simple file transfer, and the DHCP protocol for automatically allocating IP addresses. In this section, we will introduce Internet Control Message Protocol (ICMP), Internet Group Manage

Because of the network, and file system, read and write data interface compared to use the network to send and receive data interface The most abstract concept is the socket. Network Transceiver Interface is a set of BSD defined interface, file system is open and close of the corresponding. The first thing to understand is the initialization of the

Internet friends should be very familiar with what is an IP address, whether it is set to log on to the Internet, or LAN Settings, more or less access to the IP address. In fact, IP itself is a network protocol, and currently we commonly use IP protocol strictly speaking as IPv4. The following describes the IP, IPv6, TCP, and TCP/IP protocols.IP protocolDescripti

Performance of network protocolsNow it's our turn to actually control things.The performance of network processing is not proportional to the addition of delay time.This is because the intrinsic operation of most network protocols is bidirectional information exchange.The remainder of this chapter focuses on understanding why these exchanges of information are ge

message sender sent the same message.TCP and UDP are common means of communication and play different roles under certain conditions. Specifically, the differences between TCP and UDP are mainly expressed in the following areas:(1) TCP is a connection-oriented Transmission Control protocol, and UDP provides a non-connected datagram service.(2) TCP has high reliability, ensure the correctness of transmission data, no loss or disorderly sequence; UDP d

IP Control Protocol The IP protocol is only responsible for transmitting IP packets and cannot detect and control problems in the network. These tasks are completed through the Internet control protocol. ICMP (Internet Control Message Protocol) (1) The IP

, the campus network is believed that most people have used, in the campus network settings There is a 255.255.255.0 thing, this is the subnet mask. The subnet mask is a binary number sequence of 32bit, in the form of a series of 1 and a series of 0, for example: 255.255.255.0 (binary is 11111111.11111111.11111111.00000000) for the B-class address just now, Because 210.30 is the

Poly-low coupling: High cohesion: Each module functions as single as possible, does not have multiple function doping Low coupling: Minimizing the correlation between each module Network protocol: The rules that must be complied with in the network communication, such as what connection is established, how message structure is pars

This article we continue through the network analysis expert analysis system to help better solve and deal with the actual problems of the network, through its own powerful analysis system quickly locate the fault, in the first time to solve the problem. One, the more effort to monitor MSN: Perhaps monitoring MSN Chat will violate the privacy of employees, but in the case of a business ban chat through mo

Fluke network's distributed analyzer (OPV-WGA, hereinafter referred to as WGA) analyzes the distributed switching Environment Network with a new method, allowing users to view the entire layer-7 network in the most rapid and simple way as needed. WGA works with the network monitoring Console (NIS-OPV) and Protocol Anal

Network Protocol Model Analysis Network Protocol designers should not design a single, huge protocol to complete the details of all forms of communication regulations, but should divide the communication problems into multiple small problems, then a separate

Computer network refers to the different geographic locations of multiple computers with independent functions and their external devices, through the communication lines connected together,Under the management and coordination of network operating system, network management software and network communication

Basic conceptsA set of rules, standards, or conventions established by network protocols for data exchange in a computer network.ElementsThe network protocol consists of three elements:(1)Semantics。 Semantics is the interpretation of the meaning of each part of the control information. It specifies what kind of control information needs to be emitted, as well as

NetBIOS protocolNote: NetWork Basic Input/Output System (Basic NetWork Input/Output System) is a small LAN developed by IBM and mainly used for dozens of computers. The NetBIOS protocol is an application programming interface (API) that can be used by a program on the LAN. It provides a unified command set for the program to request low-level services, it serves
