Ason Technology In The Transmission Network Planning Applications And Key Technologies

With the advent of the information age, communications business types are increasingly rich, one can automatically complete network connecting the new network concepts-automatic switching optical network (ITU-T SG15 named ASON) came into being.ASON technology learned the intelligent IP network features through existing optical transmission online increase control plane, make optical transmission network have more flexible network dominate, strengthened the Internet use efficiency and fast network protection restore ability, and have MESH networking, main business provides SLA function characteristics, This thesis mainly discusses the key technologies ASON research, based on the GMPLS RSVP-TE and CR-LDP signaling protocol analysis and comparison, routing technology and automatic detection technology etc undertake careful study.Shaanxi unicom company transmission network is for mobile network, data networks, telecom support network, value-added service network and various broadband business etc. This series of circulation, provide transmission service network of network platform, For growing various business still exists dynamic bandwidth allocation, difficulties, the establishment of need artificial link finish, network maintenance workload big, business scheduling complex series of problems.Combining with shaanxi unicorn xian transmission network current ring network capacity, safety, expansibility analysis, according to the new business needs through calculation, analysis and prediction result reasonable planning design, select the appropriate nodes, and complete network modeling result of reconstruction for measuring analysis; Then through ASON intelligent characteristics for business planning, business strategy simulation planning, business routing planning simulation, Finally from the network capacity, network structure, network resources, operation and maintenance management result is analyzed. Through the planning design and optimize the work aspect indicators have greatly enhance, for ASON technology in transmission network planning application provides new ideas and methods.
