【摘要】 越来越丰富的网络应用对网络功能和性能提出了更高的要求。车联网需要网络满足低时延和高可靠性要求;远程医疗需要网络有确定性时延和安全保证;工业互联网要求网络满足大连接要求;AR/VR应用要求低时延和高带宽;量子计算也对网络安全等方面提出了新的要求。现有的IP网络由于自身架构的局限性,只提供尽力而为的服务,无法满足未来网络应用需要。调研未来20年内的网络应用,分析未来网络应该具有的功能和性能,通过对车联网、远程医疗、工业物联网、AR/VR和量子计算应用场景的描述,分析满足这些场景分别需要的网络性能,得出未来网络的性能指标。更多还原

【Abstract】 More and more network applications place higher demands on the network functions and performance. Internet of vehicles requires the network to support low latency and high reliability, telemedicine requires it with deterministic latency and security assurance, the industrial internet requires networks to meet large connections and high reliability, AR/VR applications require low latency and high bandwidth, quantum computing also brings new challenges to network security. Due to the limitations of its own architecture, existing IP networks only provide best-effort services that cannot meet the needs of future network applications. Future network applications in the next 20 years were investigated, the functional and performance of the future network were analyzed. By describing the application scenarios of internet of vehicles, telemedicine, industrial internet AR/VR and quantum computing, the network performance to meet the needs of these scenarios was analyzed and the performance indicators of future networks were obtained.更多还原
