The Design And Implementation Of Backbone Transport Network Of 100G OTN System In HeBei Radio And Television Network

With the development of communication technology,the "triple play" deeply,increase the number of users and increase bearing business type,traditional transport network technology of HeBei can not satisfy the requirements of various services and applications.In order to meet the growing demand for bandwidth,the upgrading of the 100 G system is carried out.Based on the development status and technical analysis of 100 G,combined with the broadcasting network status of Hebei,the design and implementation of the backbone transport network 100 G OTN system are carried out.This thesis firstly introduces the basic theory of 100 G OTN system,the standard and application status,through the analysis of the key technology of 100 G network and contrast analysis of the 100 G OTN construction mode.Then according to the basic situation and network architecture of Hebei photoelectric network,this thesis focuses on the current network needs and bandwidth bottlenecks analysis.The upgrade capacity is allocated in the network design through the reasonable relay allocation and the incorporation of channel capacity planning what greatly improves the utilization of the network and makes network bandwidth bottlenecks avoided.After that,according to the network characteristics and current network situation of 100 G,the network structure diagram,the channel allocation map,the node configuration diagram of city bus and the network management system diagram are given for the scheme design and system implementation of the network of 100 G OTN system in Hebei trunk network.Meanwhile,this thesis makes the 100 channel OTN system run in the central and the south outer ring of the Hebei provincial radio and television trunk network.The use of double independent loop system in the north outer ring alleviates the network pressure and improves the network utilization.Finally,this thesis introduces the network situation and the configuration of some specific business after the network upgrade.The feasibility and reliability of the design were verified through the application and test of the upgraded 100 G system in this thesis.
