Notes on data communication and network-wide area network SONET/SDHThe high bandwidth of optical fiber is suitable for carrying large amounts of data at the same time in today's high data rates and low rates. For this reason, optical fiber and the need for data rate or high-bandwidth transmission technology to develop together, and then there is a need for standa

1. Introduction The Synchronous Optical Network (SONET, representing synchronous optical networking) is a standard for digital information communication using optical fibers. In order to transmit a large number of telephone and data services, it has been developed to replace the quasi-synchronous digital system (PDH) system, which is defined by Telcodia's gr-253-core. 2. Summary SDH (representing the synch

Synchronous Optical Fiber Network (SONET) is an optical fiber transmission standard that focuses on the physical layer in the OSI model structure. Like SDH in the world, SONET was initially designed for the transmission of voice traffic over optical fiber networks. Like the first layer physical layer protocol, SONET is

The development of the routing industry has also promoted the upgrade of the broadband backbone network technology. In terms of the network structure, the broadband backbone network will develop towards high efficiency in the future, improve the service quality, traffic monitoring, and network management functions to a

), the crisis of circuit-switched network is obvious. For the major operators, the expectation of NGN is not to tear down the existing network to create an ideal NGN model, but how to evolve from the existing network to NGN, and strive to maintain the dominant position in the increasingly competitive business market. Obviously a standardized optical control plane

With the rapid growth of Internet users and web numbers, the Internet's demand for bandwidth has increased dramatically. According to statistics, every 6-9 months, the main ISP's Internet backbone link bandwidth will increase by one times, link rate will increase from oc-3/stm-1 to oc-48/stm-16 or oc-192/stm-64 or even higher. It is predicted that the data will be the most important information flow on the future network, it will bring the most profit

Intelligent Optical Networks are still quite common. So I have studied the network interface technology of users in the automatic switching Intelligent Optical Networks. I would like to share it with you here and hope it will be useful to you. To establish a dynamic connection between a client, such as an IP address, an ATM, or a SONET device, and an optical transmission

network resources including PDH, sdh/sonet, DWDM, etc., which affect the flexibility of network organization, the validity of network and the expansion of new business. To this end, international standardization agencies such as ITU-T, OIF, ODST and IETF have proposed the draft of automatic switching transmission

fiber access network (OAN) is divided into two types: Active Optical Network (AON) and Passive Optical Network (PON and PassiveOpticaOpticalNetwork. Ii. Active Optical Fiber Access NetworkActive optical networks can be divided into SDH-based AON and PDH-based AON. CE (a local device of an active Optical Network) and R

feature of frame relay is that it provides Congestion Control and Quality of Service (QoS), which will be introduced later. ATM Asynchronous transfer mode (ATM) is a cell relay protocol designed by the ATM Forum and adopted by the ITU-T. The combination of ATM and SONET (for an introduction to SONET, see previous article: http://blog.csdn.net/todd911/article/details/9324615) will allow high-speed Interconn

Optical network operators have not broken the so-called "configuration bottlenecks." They have struggled to meet the need for physical transmission and deployment of hardware platforms with unprecedented port density and throughput. But many operators underestimate the complexity of configuring a business in a multi-vendor (or multiple-business) environment.
