Abstract


With the issuance of 3G licenses and the development of broadband services , operators carrying business is turned upside down , a voice from the past, a lot of data and a small amount of business, and now the rapid growth in data services , operators carrying network especially metropolitan transport networks , due to its technical limitations already can not meet the load requirements of the new era . OTN ( Optical Transport Network Optical Transport Network ) technology is a new kind of optical communication technology , which combines the advantages of metropolitan transport networks in the past , with its high-capacity scheduling , powerful operation and maintenance management capabilities and flexible networking way , and other characteristics , has become a focus on metropolitan transport network operators and technology investment . The paper first analyzes the the metropolitan transport gateway key technology and application status . And device types , applications , network formation and protection programs focusing on the OTN technology research and analysis , and discuss equipment selection recommendations metropolitan transport networks OTN technology introduced . Finally , I participated in Wuxi Telecom OTN technology - based metro transport network design project , select the application of the actual metropolitan transport networks , technology selection, equipment selection and network formation were explored and analyzed , and on this basis to focus on OTN technology with scheduling layer cross- networking mode program design ideas and network structure . Due to the introduction of the core scheduling layer , using multiple core nodes characteristics , the design to meet the greater demand for the engineering data , and cover a wide range of requirements . The project was put into use to prove -based the OTN technology can enhance the transmission network carrying high-bandwidth IP services , scheduling , and management capabilities .
