The Application Of IP RAN In The Carrying Network Of Nanjing Telecom Integrated Service

With the fast increasement of various data services(i.e.3G)there has been an obvious trend for full IP centered service in future networks.IP Radio Access.Network(IP RAN)technologies present good solution for packet service transporting and carriergrade quality of service which focus on the study of IP RAN.This thesis presents a comprehensive on IP RAN technologies.To adapt to the needs of the change of the mobile network,it is tend to IP and broadband,the radio access network transformation to IP RAN has become the inevitable trend.As the base support network of the telecommunication industry,inorder to meet the demand of bearer services,the transmission network is developmented to priorer to services.It must have the features,such as multi service bearer?highspeed?high quality QoS?scalability,and so on.It makes the domestic telecom operators pay more attention to the reliability and the flexibility of the network,because of the full service operateing and the competition.This paper puts forward an integration scheme of multi-service carrying network based on the introduction of the technical principle and index of IP RAN.By forming an integrated multi-service test platform,the paper aims to evaluate the feasibility of using it to carry the targeted network in the future.The test results show that the scheme of L2VPN+L3VPN in this paper maintains high rate,fine Qos and high reliability,which to some extent enriches the experience in multi-service carrying network and metropolitan area network,and provides technical reference for future network development.
