Analysis of SD-WAN Standard System Architecture
According to the "Key Technical Indicator System for Software-Defined Wide Area Network (SD-WAN)" issued by the Ministry of Industry and Information Technology, the standard constructs an evaluation framework from three dimensions: service capability, solution, and equipment technology:
Dimension First-level indicator Key technical characteristics Service capability Basic functions Quick activation, business elasticity, and full life cycle management Security protection Triple security mechanism (communication/data/user) Quality assurance End-to-end availability ≥ 99.9%
Details of core technical indicators
1. Service technical indicators
Automated deployment requires support for more than five deployment methods such as edge devices through DHCP/email/SMS, etc. A typical case is that an operator completed the deployment of 200 nodes in 2 hours.
2. Solution indicators
In a financial case, the dynamic routing function was used to achieve the following:
- Transaction system link switching time ≤ 50ms
- Video conferencing prioritizes bandwidth
Standard evolution and implementation recommendations
Compared with the 2019 version of the standard, this version adds:
- Mandatory support for national encryption algorithms SM2/SM4/SM9
- Controller remote disaster recovery requirements
- Multi-tenant data isolation specifications
Implementation recommendations: It is recommended that enterprises build in three stages: ① Basic network virtualization ② Intelligent traffic scheduling ③ Fully automated operation and maintenance
