网络发展趋势:从普适通用到场景专用的网络定制

Computer networking trends:from generalizing to scenario specific customizing

传统的IP网络体制具有互联互通互操作等优点,得到了广泛的部署应用。然而,随着许多领域的用户对网络的可管可控性、安全性、服务质量、移动性、生存性、确定性、灵活性等诸方面要求的不断增长,传统的IP网络体制越来越难以满足需求。通过对领域网络差异化需求以及差异化特点的分析,结合新型网络、网络软件化等技术的发展积累,可以认为,基于领域网络特点进行网络定制将成为未来领域网络的重要发展趋势。论述了领域网络定制的必要性和可行性,首次提出了一个领域网络定制模型,即基于多维属性的领域网络定制模型,并从3个方面、6个维度探讨了基于多维属性的领域网络机制化方法,可以为领域网络定制提供参考借鉴和技术支撑。

The traditional IP network has the advantages of interconnection and interoperability,so it has been widely deployed and applied in many fields.However,for domain specific networks,it is increasingly difficult to meet the increasing requirements for network controllability,security,quality of service,mobility,survivability,determinability,flexibility,and so on.Through the analysis of different requirements and characteristics of domain specific networks,and the consideration of the development and accumulation of new network architectures,network softwarization and other technologies,we believe that the network customization based on the characteristics of domain specific networks will become an important development trend in the future.This paper discussed the necessity and feasibility of domain specific network customization,proposed a domain specific network customization model(DSN-CM)based on multi-dimensional attributes of domain specific networks,and discussed the mechanism of domain specific networks based on multi-dimensional attributes from three quadrants and six dimensions,which can be used to conduct the customization for domain specific networks.
