Application of integrating VC cross-connecting function with OTN system by Heping LIN, Cheng WANG, Jinliang ZHANG, Jixian CAO, Zhiying GAO, Shuai KANG

“…Due to the advantage of rigidity pipeline,SDH is irreplaceable in carrying high priority service circuit.However,it will withdraw because of equipment ageing.A solution of OTN system with VC cross-connecting function was proposed for the situation which SDH network faced,which could minimize space requirements,conserve energy,save the resource of optical fiber and reduce the operational risk while keeping the advantage of OTN high bandwidth transmission.Pilot testing proves that the system works well and accords with correlative criterion.…”

A method of planning and designing transmission networks for government and enterprises based on a rectangle-like distribution model combined with heat maps by Shuchong NAN, Cheng CHEN, Xunbiao LIAN, Han WANG

“…The circuit direction and service access point of the special line service for government enterprise group customers are decided by the customers themselves, and the service opening is extremely unpredictable.In order to effectively solve the problems of strong subjectivity, difficult adjustment, long cycle and low efficiency in the service opening of government and enterprise customers, a typical simulation environment and a quasi rectangular distribution model was built, and two deployment strategies combined with the thermal map were proposed.The simulation analysis shows that under the same conditions, the number of VC-OTN (VC cross connecting function with optical transport network) points meeting the coverage requirements decreases with the increase of the maximum access distance, the client point coverage increases with the increase of the deployed VC-OTN points, and the deployment benefit of strategy 2 (group coverage by maturity) is higher than that of strategy 1 (priority coverage of hot spots).When the coverage requirements are met, the number of VC points required by the theoretical minimum, strategy 1 and strategy 2 are 26, 58 and 50, respectively.This method provides reliable theoretical guidance for the accurate and rapid construction of network system, avoids blind deployment, improves the accuracy of deployment planning, and provides construction reference ideas for the subsequent construction of urban VC-OTN nodes.…”
