solution: Using Fiber/userspacethread, the Chinese translation of fiber/user space thread, please read it here. After the select thread receives the reading signal, it still performs decoding. if the message is incomplete, it switches the current execution thread to the select execution thread. In the line that says, it suspends the current fiber and switches t

of the access method, the optical fiber access and ADSL access are as follows: The initial cost of optical fiber access is relatively high. users need to purchase a pair of optical/electrical conversion devices (commonly known as optical cat) during access. The optical fiber laying process is time-consuming and cannot be withdrawn once the cost is invested. In a

considered by Internet cafes, ADSL is a little slower than optical fiber, but it is more stable. Therefore, the access method of ADSL is a suitable choice for Internet cafes. From the perspective of the cost and fee level of the access method: The initial cost of optical fiber access is relatively high. users need to purchase a pair of optical/electrical conversion devices (commonly known as optical cat) d

The other party cannot hear me. Symptom: Why can't I hear the voice of the other party when I dial the modem? I used the phone dialing program under WIN 98 and tried at command to dial up directly. Modem calls are not allowed. Method: special software is required. Step: omitted. Note: The Voice function of modem can be achieved only through corresponding softwar

The fiber channel refers to the network channel (FC. Since fiber and re have only one word difference, many misunderstandings have emerged. FC only represents the fiber channel, rather than the fiber channel. The latter is translated as an "Fiber Channel", and even a disk w

Cable Modem is developed in recent years, mainly for CATV network data transmission. Most new cable networks now use fiber-optic coaxial hybrid (HFC) networks, and their huge bandwidth and relative economics make them attractive to cable companies and newly established telecoms companies. Because cable modem is a kind of equipment that provides data service on HF

conversion devices (called optical cat) during access. The optical fiber laying process is time-consuming and cannot be withdrawn once the cost is invested. In addition, the cost is relatively high, and the payment is generally based on monthly rent. ADSL access can be directly modified on the existing telephone line, without modifying the signal transmission line, without punching through the wall and laying another cable, the normal copper telephon

line ADSL and G. Lite modem for data services and INTERNET access) or for broadband-based VDSL residential buildings for video and data services ). The home gateway RG is the same as the local HDT. It provides network connections and allocates all services to various residential network elements. The RG device is the network interface of all network structures including fttn fttc and FTTH, so it can adapt to the smooth transition of various configura

IP protocol-based fiber channel FCIP or FC/IP is an IP protocol based on the storage network technology, which is developed by the Internet Engineering workgroup IETF. FCIP allows optical fiber channels to transmit data between SAN devices on an IP network. This capability also facilitates data sharing in a geographically dispersed enterprise. FCIP is a method for transmitting storage data through an IP net

of optical/electrical conversion equipment (commonly known as the Light Cat), the fiber-laying process is time-consuming, and once the cost of investment can not be withdrawn. And its tariffs are more expensive, generally paid by the way of monthly rent. 　　 ADSL access can be directly in the existing telephone line modification, do not need to transform the signal transmission lines, do not have to go through the wall punching, another cable, can c

it. Pay attention to the purchase of light cat, photoelectric converter, optical transceiver must pay attention to the interface type, do not buy the interface wrong on the line, in addition to the attention is a single mode or multimode, now the general enterprise is a single mode. Common interface has FC (round with Thread), SC (card-type square), ST (head inserted after the rotation of a half week with a card mouth fixed). "Netizens ask questions": Often hear someone mention the light cat,

Many friends do not know how to set the fiber-optic router, the next small series will be for the small white friend all-round introduction. How to set up fiber-optic router setup graphics and text tutorial In fact, the fiber optic cable and our ordinary telephone line is similar to the difference, the difference is that

Modem dial-up Internet in Linux In the broadband access has not come into the tens of thousands of households, we have to connect to the Internet, or to drive the "cat", so for many netizens, modem is a very lovely thing. Windows provides a good support for modem, making it easy to install modems. But it's not so good to install this lovely thing under Linux.Firs

supply unit at a very high cost and cannot meet long-term business requirements in the case of persistent power outages. As the final network form that provides fiber to the home, FTTH removes the entire copper wire facility: feeder, wiring, and wire introduction. For all broadband applications, this structure is the most robust and long-term future solution. It also removes all maintenance work required by copper wires and greatly prolongs the netwo

The most important thing for us to use a computer is to access the Internet. We need to complete basic installation settings. The most important part is the installation and setup of the modem. Generally, the Modem can be divided into the following four categories based on the Modem format and installation method:1. ExternalThe external

My ADSL "CAT" was under attack. For this reason, I asked the kitten to cultivate "internal strength" and "security. The following describes how to cultivate secrets ". Recently, my ADSL Modem often experienced problems. Sometimes I can work normally when I start the system, but most of the time I cannot connect to the web page. After a while, I restarted the ADSL Modem again. At first, I thought it was a pr

ADSL technology, which can economically transmit several megabits of information per second on the twisted pair copper line. It supports traditional voice services, it also supports data-Oriented Internet access. After the local ADSL Access multiplexing device multiplexing data traffic, it selects a route to the group network to transmit the voice traffic to the PSTN, ISDN, or other group networks. Cable modem can provide high-speed data communicatio

require special network devices and special protocols. You only need to install the Modem on the monitored OAMP and the Centralized Monitoring Workstation, install the remote monitoring server and the customer on the Windows platform respectively. The server software at each site is in the waiting status. On the workstation of the centralized monitoring room, dial in the OAMP that connects to various bureaus to display the OAMP monitoring content loc

Optical Fiber Communication is a communication mode in which various electrical signals are modulated by optical fibers. Optical Fiber Communication is different from wired communication. The latter uses metal media to transmit signals, while optical fiber communication uses transparent optical fiber to transmit light

In the preceding section, we introduced the two most common ways to configure ADSL and their respective purposes, now we will take the Web method as an example to describe the many configuration options that may be encountered when configuring the ADSL modem.Detailed Web configurationIn the web configuration interface, the following describes the detailed content in the order of each tag. In most options, the detailed explanation and description are provided.The system management configuration s
