基于业务感知的下一代网络服务质量管理模型

下一代网络(NGN)是基于软交换、业务网与承载网分离的多业务融合网络。由于其多业务特性,出现了对业务流进行区分的业务感知技术,并将在NGN中起重要作用。NGN结构及特性的革命性变化,也对NGN的网管技术提出了新的要求,带来了新的挑战。NGN的多业务特性要求其网管技术能够实现对业务层面的管理和监测,从而为NGN提供高品质业务打下基础。文中提出了一种能动态业务感知的网管监测系统的智能代理结构模型。

Next Generation Network(NGN) is a multi-service integrated network bas ed on soft-switching and the separation of service network and carrier network. Due to its multi-service feature service-aware technology that differentiates th e service stream has emerged and will play an important part in NGN. Revolutiona ry changes in NGN architecture and its features also put forward new requirement s for NGN network management technology and bring about new challenges. The mult i-service feature of NGN requires that its network management technology is capa ble of monitoring and managing the service layer so as to lay the foundation for high quality NGN service. In this paper a service-aware-based model with intell igent agent architecture for network monitoring and management system that can s ense the service dynamically is presented.
