新一代网络QoS研究

Research on QoS in Next Generation Network

随着网络技术和应用的飞速发展,互联网的接入形式以及网络应用日益呈现出复杂、异构和泛在等特点,当前的网络已经暴露出诸多不足,在很多方面无法满足用户对服务质量(QoS)的要求.当前互联网的QoS体系结构及相关技术已经不能适应新一代网络应用的进一步发展.文章着眼于未来互联网的发展方向,从网络QoS体系结构、实时QoS保证、融合QoP的QoS控制以及QoS性能评价理论等几个方面论述新一代网络QoS面临的挑战和解决思路,探讨了新一代网络QoS的发展方向.

With rapid development of the network technology and application, Internet access and network application form become increasingly complex, heterogeneous and ubiquitous. The current network has revealed many inadequacies. And it is unable to satisfy Quality of Service （QoS） requirements. The current QoS architecture of Internet and related technologies can not adapt to the further development of the next generation of network applications. This paper focu- ses on the future direction of development of Internet, researches the challenges and the solving ideas of next generation network QoS from the network QoS architecture, real-time QoS, the integration Quality of Protection（QoP） and QoS, and the theory of QoS performance evaluation.
