摘要:

网络流量规模高速增长且视频化趋势日益严重,使得传统网络为了数据传输而设计的体系架构在服务质量(QoS)保障、灵活性、可扩展性等方面经受着严峻的考验。工业界和学术界提出了很多新型网络体系结构,力求在体系结构层面增强网络的QoS保障能力。从“改良式”和“革命式”两种思路对互联网新型服务质量保障技术进行了详细分析,并介绍了可重构网络的宏电路技术且给出了部署考虑。可重构网络体系结构能以其对业务的适应性、功能的可扩展性等特点,适应未来网络业务发展,满足现有网络兼容融合演进的需求,为未来网络的QoS保障设计提供了一个解决途径。

Abstract:

The scale of network traffic grows rapidly and the video trend of network traffic is becoming more and more serious, which make the traditional network architecture designed for data transmission can hardly satisfy current demands in quality of service(QoS)guarantee,flexibility,scalability,and other aspects.Industry and academia made a lot of new network architecture, aimed at enhancing the QoS capability at the architecture level. New internet QoS guarantee technology in both“incremental”and“clean slate”aspects was analyzed explicitly. In addition, wide-sense circuit and its deployment were introduced. Reconfigurable network architecture can adapt to future application development network and meet the compatible integration of evolution needs of existing network, with the characteristics of its adaptability to applications and functions scalability, providing a solution for the QoS guarantee of future network.

Key words: network architecture, quality of service, programmable network, reconfigurable network, wide-sense circuit
