Computer network failure is unavoidable. The network fault diagnosis is the important work of network management after the campus network is built and run. Generally when the network occurs information is not available, can not browse the Web, and other connectivity failures, the phenomenon is relatively clear, easy to observe and locate the fault point, such a fault is not difficult to solve. But the most troubling thing is that the internet is a pass, but the network speed slows down. When fac

For network management, LAN speed is one of the most troublesome things. If the network is not pass, but can quickly find the reason, but if the network is a pass, but the speed of slow, this is the most headache. When faced with this kind of "soft" fault for the first time, some people will be helpless. This article introduces the causes of such "soft" failures and their elimination methods, so as to improve the ability of dealing with practical problems. One, network cable problems caused by

pairs of wires in strict terms to reduce crosstalk and background noise effects. At the same time, only 1, 2 and 3, 64 lines of twisted pair are used in the T568A standard and t568b Standard, of which 1, 2 are used for sending, 3, 6 for reception, and 1, 2 must come from a pair, 3, 6 must come from a winding pair. Only in this way can we minimize crosstalk and ensure data transmission. Not according to the correct standard (T586A, t586b) production n

or more Wan IP addresses, or public or Internet IP addresses. Generally, you must pay the ISP for the wan ip address before applying for it. The Wan IP addresses cannot be repeated. (WAN and LAN) the data exchange between computers must be converted through the NAT Network Address Translation of the router or gateway. Currently, the WAN Port provided by the wireless router is generally a 10/100 Mbps adaptive RJ45 port, which can be connected to devic

ADSL is currently the most mainstream broadband access method, while wireless is currently the most popular network access method. The encounter between the two will naturally attract the attention of many readers or users. Let's take a look at several forms of ADSL and wireless connections or Internet sharing, I believe you will have a better understanding of these two devices. ADSL is currently the most mainstream Broadband Access Method I. Overview of ADSL Devices A

comes with two cables for RJ45 sockets. If it is connected to the distribution frame of the 110 connection module, it is recommended that one end be connected to the RJ45 plug and the other end be connected to the 110P patch connection.A standard test report collects all data for connection performance tests in the ISO11801 standard. It should be noted that two operators with communication tools or walkie

optical fiber network products are mainly used to achieve high-speed network connection between working group switches and computer equipment in the LAN. The main plastic optical fiber network equipment is as follows. A Plastic Optical Fiber Department switch can provide multiple Ethernet Optical Fiber ports to provide high-bandwidth and high-performance Optical Fiber connections between Working Groups or working groups. The plastic optical fiber Nic has a computer pci nic with an Ethernet Plas

transmission bandwidth must reach MHz to reduce the effect of crosstalk between different wires, some new transmission parameters must also be defined; 2. The system needs to provide better insertion loss (attenuation) performance, so a thicker wire will appear; 3. More tests are required to determine whether the current system supports new applications; 4. design new cables to meet new performance requirements. In addition, there is a very important issue worth noting, that is, there is no ind

addresses cannot be repeated. The data exchange between a WAN and a LAN computer is performed through the NAT (Network Address Translation) of the router or gateway. Currently, the WAN Port provided by the wireless router is generally a 10/100 Mbps adaptive RJ45 port, which can be connected to devices such as xDSL and Cable MODEM or Ethernet. Common wireless route parameter 2 LAN port A Local Area Network (LAN) is a relatively limited geographical Ar

Super 6, commonly known as 6A, is a 10 Gigabit system. For testing, it is necessary to achieve a MHz test, divided into unshielded and shielded systems. For a non-shielded system, a 6 packet 1 External crosstalk test is required. Currently, FLUKE and ajelun both have this test instrument. The unshielded structure is currently popular on the basis of the six categories. The Twist distance is more dense and the wire diameter is thicker. The most important change is the change on the PVC outside, a

. Twisted Pair wires are divided into shielded twisted pair STP and Unshielded twisted pair UTP. Unshielded twisted pair wires have outer cables as shielded layers, which are suitable for scenarios with low network traffic. Shielded twisted pair wires have a sheath, which has strong resistance to Electromagnetic Interference EMI (Electromagnetic Interference) and are suitable for high-speed network protocol applications with large network traffic. Twisted Pair wires can be divided into 5 categor

consists of a long Twisted Pair wires and RJ45 headers. Currently, cable twisted pair wires are sold on the market ". Most users purchase three types of cables and five types of cables. Currently, cat5e and cat5e unshielded twisted pair 1 are used. The transmission performance is 100 MHz and the transmission rate is 155 Mb/s. In addition, these twisted pair wires have the following features: The diameter is small, saving the occupied space.Light Weig

Cabling Standards and are composed of cables, wiring boards, workstation sockets, and connectors at both ends of the channel. The Optical Fiber Channel consists of FDDI multi-mode optical fiber cables, wiring boards, workstation sockets, and connection wires at both ends. 1. Costs of unshielded twisted pair Structure The following equipment must be installed: 1) 100 cat-5e unshielded twisted pair Cable data cables from the network cabling room to 100 user terminal stations; 2)

At present, broadband routers and wireless routers are becoming increasingly popular in the household and small and medium-sized enterprise markets, and readers will find that both broadband routers and wireless routers, each of them has four adaptive RJ45 lanports and at least one adaptive RJ45 WAN port. What is the difference between a similar port and a vswitch? What are their features and how to use the

must be exactly the same as that of the optical cable. Otherwise, the connectivity will fail. In addition, the types of fiber-optic ports connected to each other must be identical, Or both are Multimode Optical Fiber ports or single-mode optical fiber ports. One end is a Multimode Optical Fiber port, while the other end is a single-mode optical fiber port, which cannot be connected together. 3. transmission rate and duplex mode Unlike 1000Base-T, 1000Base-SX, 1000Base-LX/LH, and 1000Ba

Smart cabling does not change the basis of the structured cabling system. It should be a general 4-wire Cabling System Based on RJ45, but additional features are added to the communication room. The difference between smart cabling and traditional structured cabling systems is that it allows you to view jumper connections. To receive this information, you must somehow sense or record whether there is a jumper connection. Ideally, this should be automa

The Smart Home cabling system is the basis of the Smart Home System and the channel for its transmission. Next let's take a look at the cable types and common problems in smart home. Smart Home cable type 1. twisted pair (twisted-pair ). Twisted Pair wires are the most common transmission medium. They are composed of two copper wires that are insulated from each other and have a typical diameter of 1mm. The two wires are twisted together to prevent the electromagnetic induction from generating i

protocol runs on top of the UDP protocol, using the port number 53.Default gateway : Configure the default gateway to create a default path in the IP routing table. A single host can have multiple gateways. The default gateway means that if a host cannot find an available gateway, it sends the packet to the default designated gateway, which handles the packet.Note: The default gateway for a computer cannot be specified casually and must be specified correctly, or a computer will send the packet
