Abstract

Abstract:

The basic concept of SD-WAN,application scenarios and the advantages in process of cloud network integration were introduced,and the key technologies of telecom SD-WAN solution were emphasized on,including open system architecture,rich deployment pattern,EVPN over VxLAN,traverse NAT,multicore soft-forwarding,etc.A solid foundation was established for the application of SD-WAN system.

Key words: SD-WAN, EVPN, VxLAN, IPSec, soft-forwarding

VPN技术	扩展性	易用性	支持L2/L3混合路由	支持多租户
EVPN	使用BGP作为控制层协议，扩展性好	控制层协议简单	同时支持L2和L3 VPN	支持好
IPSec VPN	点到点隧道互联，扩展性差	控制层协议复杂	只支持L3 VPN	支持差，配置复杂
L2TP VPN	点到点隧道互联，扩展性差	控制层协议复杂	只支持L2 VPN	不支持
