The Project Design For CMCC Of A Certain City In GUANGDONG IP Metropolitan Area Network Optimization

On May 20,2015,China issued by the general office of the state council "about to speed up the high-speed broadband network construction promote policies prevailing worldwide network speed instruction opinion",speed up the high-speed broadband network construction to promote policies prevailing worldwide network speed targets and measures,three years to complete 10 times the bandwidth speed for the multiplication.Thus,throughout the country communication operators began to the IP metropolitan area network optimization reconstruction boom.To accelerate the construction of high-speed broadband network to promote the goal of,IP metropolitan area network communication operators across the country in 2016 the overall speed upgrade is imminent.Communication operators in IP metropolitan area network optimization reformation,however,generally faces many limitations and difficulties in the future,such as: comprehensive construction cost control,electric capacity limits convergence node computer room,business cut over risk control,etc.In this paper fully studies the domestic telecommunication operators IP metropolitan area network is typical network under the premise of network architecture,combining with the characteristics of guangdong mobile IP metropolitan area network business needs a branch and the main limitations and difficulties,a three layer structure is put forward the "core layer-control layer-business convergence layer",the structure of the second floor "core layercontrol layer " two combining IP metropolitan area network IP metropolitan area network topology optimization.In addition,this paper also carried out some branch of guangdong mobile IP metropolitan area network optimization retrofit scheme to realize network indicators before and after contrast,shows some branch of guangdong mobile IP metropolitan area network optimization to speed up construction had the family network bandwidth 10 double long after the completion of the effect of processing capacity,and made comprehensive evaluation.Finally the future development of IP metropolitan area network optimization transformation makes a brief analysis and outlook.
