    • High-level requirements specifying bandwidth, degree of featurization and quality of service are input to a network management system (NMS) in an elementary, high-level language. The NMS translates the set of high-level requirements into a set of low-level requirements using a first subroutine. A second subroutine then generates one or more options on the basis of the set of low-level requirements. Each option consists of a detailed technical specification for various elements of the underlying main network. In response to user selection of an option, the NMS converts the option to a set of graphical elements for display using a third subroutine. A cost breakdown is also provided for the selected option. The user may then commit the option to the NMS or reduce the high-level requirements if the cost is deemed too high. Subsequent to the selected option being committed, the NMS sends out the detailed technical specification to the appropriate network elements, resulting in the building of a VPN in accordance with the high level requirements. The high degree of automation enables faster service provisioning, less frequent errors and reduced training costs.
    • 指定带宽,特征度和服务质量的高级要求以基本的高级语言输入到网络管理系统(NMS)。 NMS使用第一个子程序将一组高级别要求转换为一组低级要求。 然后,第二个子程序基于一组低级要求生成一个或多个选项。 每个选项包括底层主要网络的各种元素的详细技术规范。 响应于用户选择选项,NMS将选项转换为一组图形元素,以使用第三个子程序进行显示。 还为选定的选项提供费用明细。 然后,如果成本被认为太高,用户可以向NMS提交选项或降低高级别要求。 在所选择的选项被提交之后,NMS将详细的技术规范发送到适当的网络元件,从而根据高级别的要求构建VPN。 自动化程度高可实现更快的服务配置,更少的错误和降低的培训成本。
