摘要
为了实现对下一代互联网IPVPN(虚拟专用网)业务服务质量管理和评价的规范化,保证业务正常、可靠、高质量的提供,本文定义了6个IPVPN业务等级,提出了下一代互联网支持多业务等级的IPVPN业务质量评价体系框架,并详细论述了质量评价指标的计算方法.该质量评价体系为IP虚拟专用网业务提供了一种实用有效的评价方案和评价算法.
To guarantee the well-balanced, reliable and high-quality service, the specification of service quality evaluation challenges the quality management of NGI (next generation Internet) IP VPN (IP-virtual private network) service. Six IP-VPN service grades are defined and the quality evaluation architecture of NGI IP-VPN service supporting multi-grades is proposed. Then the calculation methods and mathematics formulations are presented in detail. The quality evaluation architecture is applied to the IP-VPN service practically and effectively on solutions and algorithms.
