摘要:

回顾了数据网的发展史和标准化史,提出未来网络的分代发展理念。指出网络设计存在两条技术路线:以用户和业务应用为核心的发展技术路线,根据用户和应用需求逐步增加网络能力;以网络为核心和能力责任主体的发展技术路线,网络分代研究,网络能力“代”内稳定,无须频繁修改和增添。网络5.0(即第五代网络)采用的是“以网络为核心的设计理念”,给出了网络5.0的3项重要能力详细论述,分别是:内生可信和安全,内生的网络资源感知、调配和管控,内生网络性能和能力确定性。

关键词: 传送网, 数据网, 下一代网络

Abstract:

The history of data network development and standardization was reviewed,and the idea ofsub-generational development concept for future network was put forward.It was pointed out that there were two technical routes in network design:the development technology route with users and business applications as the core,the gradual increase of network capabilities according to the needs of users and applications,and the development technology route with network as the core and the main body of capacity responsibility.Network 5.0 adopts “network as the core design concept”.A detailed description of three important capabilities of network 5.0 was given:endogenous credibility and security,endogenous network resource perception,deployment and control,and endogenous network certainty.

Key words: transport network, data network, next generation network
