• Diverse interfaces, load balancing: SD-WAN no longer enforces the exclusive use of MPLS, but allows for multiple connection types including MPLS, the Internet, Ethernet, 4G LTE, and 5G APN. It supports the rapid provisioning of dedicated line services without the need to specify a service provider, enabling cross-operator provisioning.

• Self-selecting the optimal path: SD-WAN's uCPE and vCPE can autonomously choose the best path based on the current network conditions and configuration policies.

• Simple deployment, completed in seconds: Zero-contact deployment of devices, meaning plug-and-play. Through the centralized policy management platform, uCPE can automatically obtain configurations after being powered on.

• VPN encryption, transmission security assurance: By using Ipsec or TLS/DTLS encryption to protect data in transit, integrating NFV technology; conveniently introducing NGFW firewall technology, Intrusion Prevention Systems (IPS), cloud security services.

• Intelligent routing, ensuring critical applications: Intelligent routing technology can enhance the reliability of Wide Area Network (WAN) connections and improve transmission efficiency. Real-time link quality monitoring, comprehensively and in real-time, assesses the quality of each link - packet loss/delay/jitter.

• End-to-end QoS Management: Ensuring high-priority applications, accelerating application access speed through wide area network acceleration technologies, and improving user experience.

• Link Smooth Switching: Smoothly switch traffic to other available links when a link is unavailable, with failover occurring within 2-3 packet drops, and the lost packets can be retransmitted and reordered.

SD-WAN, as an emerging networking technology, rapidly establishes SD-WAN networks by deploying u/vCPE devices, virtual gateways, and orchestration controllers, offering flexible and swift network connectivity services to enterprise customers. It has generated significant appeal and practical demand for industries such as retail, catering, education, and healthcare.

SD-WAN technology is currently mainly applied in five business scenarios: government and enterprise branch networking, multi-cloud access, WAN application directional acceleration, retail store access, and emergency activation scenarios. The management platform system needs to support functions such as the activation and operation and maintenance management of multi-tenant services.

1.1.1 Government and enterprise branch networking scenarios

Enterprise branch networking scenarios are primarily used for the application of building virtual private networks through SD-WAN technology. Enterprise users can achieve three-layer networking needs between the headquarters and branches, or among branches, both locally and across provinces, and can carry the private network routing of internal users.

1.1.2 Multi-cloud access scenarios

With the rapid popularization of the Internet, access resources have greatly enriched, increasing the demand for enterprise branch interconnection, cloud resources, and cloud application access. Connecting through the Internet has become a more economical and flexible approach. At the same time, by utilizing SDN controllers for centralized control, automatic service distribution can be effectively expedited, accelerating the business deployment cycle, increasing the flexibility for enterprise users to order and experience services, and providing users with a rich set of network monitoring and cloud connectivity services.

1.1.3 Wide Area Network Application Dedicated Acceleration Scenarios

SD-WAN services can optimize gateway forwarding behavior through application identification and link quality monitoring, achieving optimized and accelerated forwarding performance when multiple nodes are forwarding through the wide area internet.

1.1.4 Retail store access scenarios

New retail and the rapid development of supermarkets have a very high demand for the speed of network service activation. It is necessary to quickly, flexibly, and stably establish VPN connections to achieve networking between stores and institutions, and to carry the private network routing for internal users of the enterprise.

1.1.5 Emergency Activation Scenario

With the rapid advancement of urbanization, municipal construction and road renovation projects are carried out annually in different parts of the city. The implementation of these projects poses a significant threat to optical cables, which are at constant risk of being disrupted. Since the 5G network is based on wireless data transmission, utilizing 5G gateways, and through the configuration on both the base station side and the user side, it is possible to achieve wireless 5G line replacement for wired faults that are irreparable or cannot be repaired in the short term.
