| 摘要: |
| 互联网端到端的设计原则没有区分端系统和网络间接口，使得用户分组处理期望无法告知网络，降低了网络效能。首次提出用户转发意图概念，端系统凭此向网络通告其意图，并借助网络边缘计算能力得以执行，实现用户意图在网络节点转发决策中的主动使能，构成新型主动表意网络i ECAN。主动表意网络可以在视频直播加速、物联网数据融合、端系统安全认证等场景中得到应用。基于CORE模拟器构建网络演示环境，对无线网络切换和基于主动表意网络的无线网络切换的延迟进行比较，证明了主动表意网络机制的合理性和可行性。主动表意网络扩展了新的端系统和网络之间的接口，为人-网协同提供了基础。 |

| Abstract: |
| The internet principle of “end-end” cannot distinguish host-network interface, so the intent of the user cannot be aware by the network, which decreases the efficiency of the transmission. The novel edge computing-based active network especially for user intent, i-ECAN, was proposed, and the concept of the user forwarding intent was designed, which was utilized to inform the network the intent directly by the end system and was executed on the basis of the resource of edge computing. The i-ECAN can embody the user′s intention in the forwarding decision of network nodes and be used in mobile communication, video broadcast, and data fusion in internet of things. In the wireless network based on CORE simulator, the switching time of normal wireless network and wireless network based on i-ECAN was compared, which proves the rationality and the feasibility of i-ECAN. The i-ECAN extends the interface between the end system and the network, which enforces the collaboration between machines and networks. |
