摘要
NGN(下一代网络)是以基于IP的分组交换为核心的网络,QoS(服务质量)性能至关重要。NGN通过引入控制机制、加强控制功能来为网络提供严格的QoS保证。文中分析和论述了NGN的QoS控制技术和策略,并基于ITU-T标准,对下一代网络QoS控制策略和实施方式的思路、优缺点及可行性进行了分析和比较。
OoS guarantee is a critical challenge to NGN based on packet-switched network. It is possible for NGN to provide more effective OoS guarantee by using the control mechanism. The OoS control strategies and implementations strong and weak points of NGN, including their feasibilities, are analyzed and compared in this paper.
