physical layer, which is not the same as the "frame" of the data link layer that will be discussed at a later time, and cannot be confused. 3, Wavelength Division multiplexing WDM (Wavelength division multiplexing) Wavelength division multiplexing is the frequency division multiplexing of light. Because of the high frequency of the optical carrier, it is customary to use wavelength rather than frequency to express the use of more than the optical carrier, so that the use of Wave Division mult

Optical Bridge is a company set up in the United States focused on the Chinese market, its headquarters in Beijing, and in Guangzhou, Shanghai, the United States and Denver have branch offices. Optical Bridge Company in the network design, implementation, construction and after-sales service has a very professional service, because its staff over the past decade has hundreds of SDH/DWDM project management experience.Because the company's various busin

Fiber-optic Ethernet technology is now the integration and development of two major communication technologies, namely Ethernet and optical network. It focuses on the advantages of Ethernet and optical network, such as wide application of Ethernet, low price, flexible networking, simple management, high reliability and large capacity of optical network. The high speed and large capacity of optical Ethernet eliminates the bottleneck of bandwidth existing between LAN and WAN, and will become a sin

In recent years, the computer network, especially the Internet development is very rapid, ATM and IP over DWDM technology development so that the network transmission bandwidth quickly increased. While the development of network security and management technology is relatively lagging behind, although the voice of network security is high, but really fall to actually few. It is often believed that increasing the security mechanism of the enterprise ne

the focus of telecom operators, at present, there are a wide range of metropolitan area Network technology, which includes metropolitan area network based on SDH structure, metropolitan area network based on Ethernet structure, metropolitan area network based on ATM structure and metropolitan area network based on DWDM structure. In fact, SDH, ATM, Ethernet, WDM and other technologies are constantly absorbing the strengths of other technologies, each

of enterprise network, not only make the bandwidth and traffic increase rapidly, at the same time, the quality of the network requirements like the public network, has been very high, the same need to build a flexible network to meet the market and the specific needs of customers. Therefore, how to combine the optical and Ethernet to combine the bandwidth and the multiple service functions effectively becomes an important aspect of the construction of the metropolitan area network. Fundamentall

Just using Webapi,When using $.get, the response of the front and back desk is successful, but there are many problems when using the $.post method.After the search of an English material, basically reflects my problem, now selected passage as follows:The Web API is good, but the post parameter problem requires some means, there are three things you need to know1, to pass the basic parameters in, must be marked with "Frombody"public string Post (string value)The post function even executes, but

they are directly connected to users, remote management is required for functional features such as VLAN and address filtering. 10G switch: Communication Between TCP/IP and Telecommunication Network With the increasing popularity of Gigabit Ethernet to desktop, 10-Gigabit Ethernet technology will be widely used in the aggregation layer and backbone layer. However, in terms of the current network situation, the first application of 10-Gigabit Ethernet will be the backbone of the education indust

Ethernet technology is based on layer-4 LAN switches, layer-4 LAN switches, SONET devices, and DWDM. Some companies have introduced fiber-optic Ethernet switches. These switches have multiple features and can ensure service quality as much as possible (such as packet classification and congestion management ). Such products may require the following key technologies and Performance: high reliability, high port density, service quality assurance, and

Ethernet switches are still commonly used. So I studied the Ethernet switch access solution and shared it with you here. I hope it will be useful to you. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely, Ethernet and optical network. It integrates the advantages of Ethernet and optical networks, such as common Ethernet applications, low costs, flexible networking, simple management, high optical network reliability, and l

The Extreme silicon technology can easily identify the hardware. The application exchange technology can perfectly support the layer-7 Application exchange function, and also include the ability to perform syntax analysis on Webpage requests. When optical network technologies such as DWDM and frequency division switching rapidly increase network capacity, the bandwidth will become ample. However, how to make better use of bandwidth, how to manage onli

DWDM/CWDM interface to work with optical transmission. The performance was constantly improved. It supports RPR networking technology, MPLS, and fast Spanning Tree Protocol, the integrated data, voice, and video services that can be managed and Intelligently Based on the IP platform will be gradually implemented, qoS, security, content distribution, MPLS, and other business features and solutions support will be the ultimate direction of Ethernet dev

China's IP routers have developed rapidly and their technology is also very mature. Many people may not understand the connection between IP Routers and SDH devices of the IP transport network, after reading this article, you must have gained a lot. I hope this article will teach you more things. In recent years, the broadband high-speed Internet, with the IP technology as the core and SDH or DWDM as the bearer, has developed rapidly. IP Over SDH is o

departments or floors of an enterprise. Of course, these Ethernet switches must have excellent performance. At the same time, due to the direct connection to users, remote management requirements are also very high for functional features such as VLAN and address filtering. 10G Ethernet switch: Communication Between TCP/IP and Telecommunication Network With the increasing popularity of Gigabit Ethernet to desktop, 10-Gigabit Ethernet technology will be widely used in the aggregation layer and b

SONET device, and a DWDM device. Some companies have launched fiber-optic Ethernet switches, which have multiple features and can ensure service quality as much as possible (such as packet classification and congestion management ). Such products may require the following key technologies and Performance: high reliability, high port density, service quality assurance, and other functions. Fiber-optic Ethernet is more cost-effective than other broadba

solution that people talk about a lot about. Whether or not H.235 can be used can ensure security, and the corresponding cost and control problems need to be carefully considered. In addition, for IP Phone devices that adopt confidentiality measures, different vendors may need a coordinated process in terms of interoperability. 3. Service Quality In addition to address and security, another important issue is service quality. The current IP network has inherent defects in service quality suppor

light Single-Mode Optical Fiber: optical fiber that transmits light forward without multiple reflections Frequency Division Multiplexing (OFDM): After a user allocates a certain frequency band, the user occupies this frequency band throughout the communication process. All users use different bandwidth resources at the same time. Time division multiplexing (TDM): divides the time into long time division multiplexing frames (TDM frames) such as segment. Each time division multiplexing user occup

transmission rod routes are generally optical fiber cables and power cables mixed into one pole for transmission.1.3 SDH TransmissionSDH is called the Synchronous Digital System, which unifies the rate level, network node interface NNI, and frame structure of digital communication. SDH is to synchronous transmission module STM form to transmit, according to the level divided into STM-1: 155 Mbit/s (155), can accommodate 63 2 m; STM-2: 622 Mbit/s (622), can accommodate 4 155; STM-3: 2.5 Gbit/s (
