摘要
政企集团客户专线业务的电路局向、业务接入点均为客户自行决定,业务开通存在极大的不可预见性。为有效解决政企客户业务开通的主观性强、调整难度大、周期长及效率低等问题,搭建典型仿真环境,构筑类矩形分布模型,结合热力图提出两种部署策略。仿真分析可知,相同条件下,满足覆盖的需求VC-OTN(VC cross-connecting function with optical transport network)点数随最大接入距离增大而减小,客户点覆盖率随部署VC-OTN点位增大而增大,策略2(根据成熟度分组覆盖)部署效益高于策略1(优先覆盖热点区域)。满足覆盖率需求时,理论最小、策略1和策略2所需VC点位数分别为26个、58个和50个。为网络系统精准快速建设提供可靠理论指导,避免盲目部署,提升部署规划精度,为后续搭建市区VC-OTN节点提供建设参考思路。
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.
