, and the WEB is becoming a service platform from a content delivery mechanism, a large number of services and applications (such as news services, internet banking, E-commerce, etc.) are all around the web. This has contributed to the dramatic growth of Internet users and the explosion of Internet traffic, and Figure 1 shows how the number of Internet-connected hosts changed in 1995-2000 [1], and the growth trend is more rapid than ever. Figure 1: Changes in the number of Internet

With the improvement of social informatization, information demand has been developed from simple data information to interactive multimedia information, from special service to digital, voice, image Unified service and integrated network. The traditional IP network has been unable to meet the needs of new business, the development of new business has created a "bottleneck." In this case, the broadband IP network will emerge. The so-called broadband IP is a real-time operation to ensure the qual

Hung Lian 95 Information Industry Co., Ltd. Chen Jinzhang In recent years, communication network technology has been developing rapidly with the combination of computer network technology represented by Internet, among which communication, computer, radio and television are the basis of the integration of optical communication technology more attention of the world. Optical network expert, Hung Lian 95 chief engineer Mr. Chen Jinzhang the next Generation Optical network technology is elaborated

The new generation of intelligent optical network as a future transmission network development direction has been recognized by the industry. As a Ciena company with a history of more than 10 years, there are many unique research results and leading technologies in this field. They have more mature ideas in the composition and technology of the new generation of intelligent optical networks. ——— Editor 1. Single-Machine integrated multiple SDH devices the next generation of intelligent Optical

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprecedented rate. Currently, DWDM technology is used in the optical layer. The available bandw

Because Fiber Ethernet has the WAN function, it is bound to promote the sale of LAN Fiber Ethernet devices to operators. Here we analyze how Fiber Ethernet breaks through its Development limitations. The Optical Fiber Ethernet product can use Ethernet devices to implement WAN communication services in the format of Ethernet data packets. This technology can be applied to any optical transmission network-optical fiber direct transmission, SDH and DWDM

the cost of Route Search. Therefore, placing some frequently accessed destination ports in the cache can improve the routing search efficiency. Whether it is an input buffer or an output buffer router, there is a bottleneck in route search. In addition to performance bottlenecks, the stability of routers is also a common concern. 4. Tbit Router Fiber optic and DWDM are mature and ready-made among the three main technologies used by core internet in t

narrowband services, combined with Cable Modem and other technologies, it can economically access user-side broadband services. This is one of the commercial broadband service access technologies for users, namely, FTTC + HFCs ). The goal of Broadband Service Access Technology for users is to achieve FTTH at home through optical fiber, combined with the networking technology of PON in Passive Optical Networks and transmission technologies such as ATM and sub-carrier multiplexing SCM) and Dense

At present, the ASON routing protocol is widely used. So I have studied the comprehensive description of the OSPF-Based ASON routing protocol. I will share it with you here, hoping it will be useful to you. With the development of related technologies in the information field, especially the powerful driving force of Internet on the Growth of data services, optical networks are required to adjust the logical topology of networks in real time and dynamically to achieve optimal resource utilizatio

main performance bottleneck of a backbone IP router is the time it takes to find a route in the forwarding table. When a packet is received, enter the port in the forwarding table to find the destination address of the packet to determine its destination port. When the packet is shorter or the packet is sent to many destination ports, it is bound to increase the cost of Route Search. Therefore, placing some frequently accessed destination ports in the cache can improve the routing search effici

With the development of China's routing industry, it also promotes the wide application of the router technology. Here we analyze the VPN and IPv6 technologies in the router technology, fiber optic and DWDM are mature and ready-made among the three main technologies used by core internet in the future. If there is no router corresponding to the original bandwidth provided by the existing optical fiber technology and

replaced the traditional twisted pair access networks. Compared with other access network technologies, optical fiber access network has the following advantages:1) the transmission rate on the line is greatly improved. The optical fiber wavelength division multiplexing (WDM) technology can increase the transmission capacity of an optical fiber to the Tbit/s level, the WDM Technology of the 4-optical path enables a single optical fiber to transmit 4x10 Gbit/s = 40 Gbit/s of information simultan

High-density and highly integrated OTN Wavelength-Division transmission SystemThis wave division multiplexing technology in the heyday, a variety of new technologies emerge. The goal is the same, that is to meet the network era of the operators. Long long ago, can only use CWDM coarse wave points, channel number is not enough to say, transmission distance is also very limited, line and equipment attenuation calculation,10G no relay transmission Kilometer is already a bottleneck. This technical

products can implement WAN communication services in Ethernet packet format with the help of Ethernet devices. The technology can be applied to any optical transmission network-optical fiber direct transmission, SDH and DWDM network transmission. At present, fiber Ethernet can realize the standard Ethernet speed of 10Mbps, 100Mbps and 1Gbps, and it will become a bright spot of all kinds of business after it reaches 10Gbps.The fiber-optic Ethernet bus

other is the OXC, which is constructed using an electric switch, which is used to exchange low speed signals. It transforms the received light signal into a high speed electric data stream through photoelectric conversion, and then uses the high-speed electric data stream to solve many low-speed channels. These low-speed channels are connected to the corresponding route via electrical oxc, and then the Low-speed channel multiplexing becomes a high-speed data stream, and is modulated to a light
