互联网的设计理念与网络5.0技术

Internet design concepts and network 5.0 technologies

互联网发展了50年,其设计理念从未改变,业务网完全采用OTT方式,IP网至今还是“尽力而为”,制约了互联网的发展。要不断满足社会发展的需要,互联网设计理念需要变革,可行的方向是由“以应用为中心”变为“以网络为中心”。网络5.0是第5代数据网,与第4代数据网(IP网)相比,保留IP网的全部优点,填补了IP网在网络性能和能力上的不足,性能和能力上有质的进步。具体讨论了网络5.0在可扩展性、内生可信安全、确定性等多方面的关键技术。

The internet has been developed for more than 50 years,but its design concept has never changed.The business network is completely OTT,IP network is still“best effort”,which restricts the development of the internet.In order to continuously meet the needs of social development,the internet design idea needs to be changed,and the feasible direction is to be from“application-centered”to the“network-centered”.Network 5.0 is the fifth generation of data network,compared with the fourth generation of data network(IP network),it retains all the advantages of IP network,filling the absence of IP network in network performance and ability,with qualitative progress in performance and ability.The key technical issues on scalability,endogenous credible security,certainty and more aspects of network 5.0 were specifically discussed.
