The Design And Implementation Of IP Based Bearer Network

With the rapid development of LTE,5G business and Internet industry,communication network has become inseparable with human beings,and information interaction between people,people and things,things and things has increased convenience.Different kinds of communication services and the needs of users are springing up.The proportion of traditional voice services is becoming smaller and smaller,and data services are gradually becoming the mainstream.The rapid development of data traffic has brought unlimited business opportunities to operators,but also put forward higher requirements for mobile networks.The new IP based bearer network can carry a wealth of services,and has strong bandwidth expansion ability and excellent business support ability,so it has become the main line of the current operators' transmission network evolution and the best choice of the operators' transmission network.With the development of transmission network,IP based bearer technology has gradually replaced SDH / MSTP technology.IPRAN technology based on IP message three-layer forwarding system has emerged as the preferred IP Bearer Network of China Unicom.Firstly,the paper introduces the basic concepts,key technologies and common devices of IPRAN network,and sums up the overall idea of current IP Bearer Network.Then the network is designed from the physical topology,IP address,network protocol and other aspects,and the IPRAN network is built and tested with Huawei ENSP software.In the built IPRAN network,two sets of rectification schemes are proposed in combination with the current network situation of Xining Telecom's IPRAN.The first scheme is to improve the network security and ring rate operation scheme.The second scheme is to improve the current network IPRAN with the introduction of 5g technology The equipment rectification and replacement operation has realized the characteristics of large bandwidth and low delay.At last,it makes a simple prediction of the technology development of IPRAN with SDN technology and OTN technology.
