The press of IP traffic that enriches colorful multi-media traffic and presents a burst type growth day by day makes higher request to the bandwidth of correspondence net. The shape of top speed area net in the office and big capacity framework net makes to take ADSL as main connecting to commence the connecting of

Access Network (AN) is a Service Node Interface (SNI) and the associated user network interface (UNI) between the number of transmission entities formed to provide the necessary telecommunication services for the transmission capacity of the implementation of the transmission system load. Between users or business to achieve transmission of information between nodes, so that from

IPv6 (Internet Protocol Version 6) is the next-generation IP protocol designed by IETF (Internet Engineering Task Force) to replace the existing IP protocol (Internet Protocol Version 4). The length of IPv6 address has been extended to 128 bits to solve the IPv4 address exhausting problem and to meet the large IP addresses demand proposed by

Access network management often lags behind network construction and market demand, good management is not only to improve service quality and operational efficiency of the network, can also reduce costs, reduce the number of failures and downtime, thus increasing operational competitiveness. At present, because of the different networked devices, network management systems of different manufacturers,

With the transformation of fixed network’s business, numerous operators set about reforming the network of loading capacity. While the core of network was reformed, the bandwidth’s bottleneck problem is becoming conspicuous gradually. Although ADSL has become the main technology for access network currently, it can’t provide high-clarity or exchanging-video business. There are a series of

With the rapid development of optical communication technology and the rapidincrease in telecom operators of our country, the backbone network has been a higher-levelnetwork for optical fiber communication. However, the bottleneck between high-speed LANand the backbone network still exists. That is the ‘last mile’ access network. The new demandwith high bandwidth as the main feature

This paper has raised the possibility of using EPON technology in the construction ofcampus wireless network. It is aimed at the status of the lack of pipeline resources whenmobile operators enter into the traditional area of the existing fixed-line operators and build awireless network. With the increasing advance of optical network terminal to the users,
