摘要
本文提出了智能软件定义广域网(SD-WAN)架构，该架构将传统的SD-WAN与IPv6段路由(SRv6)相结合，实现端到端的SRv6隧道连接。与传统的SD-WAN相比，智能SD-WAN可以与底层网络集成，实现底层与叠加的协同。这样，用户购买了底层网络切片服务后，就可以使用底层网络切片等许多服务。此外，智能SD-WAN还可以提供差异化、有保障的SLA (Service Level Agreement)服务，并在云端集成虚拟网元，提供SFC (Service function chain)服务。
In this paper, we propose the Smart Software-Defined Wide Area Network (SD-WAN) Architecture, which combined the traditional SD-WAN and Segment Routing over IPv6 (SRv6) to realize an end-to-end SRv6 tunnel connection. Compared to traditional SD-WAN, the Smart SD-WAN can integrate with the underlay network to realize the collaboration of underlay and overlay. In this way, many services such as the ability of underlay network slicing when subscribers have bought the underlay network slicing service can be used. Furthermore, the Smart SD-WAN can provide differentiated, guaranteed Service Level Agreement (SLA) service and integrate virtual network elements in the cloud to provide service function chain (SFC).
