摘要
提出了一个下一代网络(NGN)定价知识支撑系统(KSS)构架,通过采集和分析SLA决策、SLA检测和评估过程数据,确定ISP运营环境中的网络、市场和政策关键性能指标(KPI),通过对KPI的分析,定义网络、市场和政策关键定量指标(KQI),基于KQI的评估,定义利润和进行价格影响预测。开发了一个KSS的基于XML的SOA实现构架,在基于SLA的NGOSS原型系统平台上进行了仿真实验,并和获得IST奖的ITDSS/TelPrice进行了比较,实验结果很好验证了它的优点。
A pricing knowledge support system (KSS) architecture on next generation network (NGN) was proposed, by collecting and analyzing the process data of service level agreement (SLA) decision, SLA detection and SLA evaluation. It obtained network key performance indexes (KPIs), market KPIs and policy KPIs of ISP. By analyzing these KPIs, each key quality index (KQI) was got, and by evaluating these KQIs, the ISP made profit margin decision and forecasted the price impact on operation environment. An XML-based SOA implementing architecture of it was developed. Simulation result on the SLA-based NGOSS primitive platform verifies its merits in the comparison with ITDSS/TelPrice which won IST award.
