In implementing an on-demand, flexible, and secure global SD-WAN networking solution, it is crucial to adhere to a set of key design principles to ensure the reliability and efficiency of the network. Through the following design principles, global SD-WAN can meet the urgent demands of enterprises for flexibility, security, and efficiency.

Flexible Overlay Network Interconnection

Global SD-WAN establishes an Overlay network between sites using IP addresses, decoupling the Overlay network from the Underlay network provided by the service provider. This allows global SD-WAN to build networks on mixed WANs, including MPLS lines, the Internet, LTE, and more. As long as the service provider’s WAN can provide IP routing reachability for the CPEs at both ends, global SD-WAN can establish Overlay tunnels between the two sites, ensuring universal and flexible interconnectivity.

Security Encryption and Isolation

To meet the security needs of different business departments within an enterprise, global SD-WAN must support encryption and isolation features. It not only supports data encryption for inter-site communication but also provides VPN isolation based on Overlay technology to meet the isolation requirements of different departments.

Support for Diverse Network Topologies

International SD-WAN should support various network topologies to meet the needs of business interactions between sites. Depending on the geographical distribution, administrative characteristics, and business requirements of enterprise users, international SD-WAN can construct various topologies, such as Hub-spoke, Full-mesh, Partial-mesh, and hierarchical networks, providing diverse business interaction experiences and meeting security requirements.

Network Business Orchestration and Automation Deployment

To enhance network agility, international SD-WAN must support network business orchestration and automation deployment. By abstracting and defining the enterprise WAN network model, customers do not need to understand technical details during network deployment. Through network business orchestration, automated configuration is achieved, reducing the complexity of enterprise WAN usage and significantly enhancing network agility.

In international SD-WAN networking design, adhering to these principles will provide enterprises with an efficient, flexible, and secure network environment. This effectively improves the network performance of enterprises, ensuring they meet the ever-changing demands of their business.
