otn optical transport network

OTN switching P-OTN effectively reduces network cost by 100 GB (2) Globally, the growth rate of mobile and Internet traffic is unprecedented. The reasons for this phenomenon include the growth of cloud services, mobile broadband, and Internet-based on-demand video streaming services. Cisco predicts that from 2012 to 2017, Internet IP traffic will triple to 120 b

deployment, this solution also causes a large amount of idle network bandwidth. From the operational perspective, both solutions are not ideal. The client service is not only bound to a specific uplink wavelength, but also because the ROADM-based network can only be switched according to the whole wavelength, any network configuration at the business layer, if t

SDH is a very mature and strict transmission network system, it has been the birth of a wide range of application support, has become the world's core network of the main transmission technology. China from 1995 on the main line began to turn to the SDH network, China's SDH transmission network is to support the number

), 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

0. PrefaceThere are many different link resources in intelligent Optical network, such as fiber link, wavelength link, various STM link and VC layer link in SDH, and various OTM layer link and och layer link in otn, etc. These links are called Sub dot (SNP) links in Ason, for the scalability of routing protocols and routing diversity, several different SNP links

Automatic Switched Optical Network (ASON) is the core transfer technology of NGN. This technology is based on the traditional optical network (SDH, DWDM, OTN, etc.), by introducing the control plane to make it have intelligent function, that is, the

1 Introduction The main difference between ASON and the traditional OTN is that an independent control plane is introduced to give the traditional optical network intelligence. ASON has three connection modes: permanent connection, soft permanent connection, and exchange connection. The first two methods do not require strict user

This article mainly introduces the network protocol overview: the physical layer, the connection layer, the network layer, the transport layer, the application layer detailed, this article uses the postman and the Post office in the life to help to understand the complex network protocol, is easy to understand, the sty
