一、With the deepening of enterprise digital transformation, traditional wide area network architecture is no longer able to meet the needs of multi cloud interconnection and flexible office. China Unicom's SD-WAN (Software Defined Wide Area Network) intelligent selection dedicated line and cloud networking products, relying on a fully SDN transformed backbone network, provide enterprises with secure, flexible, and low-cost networking solutions. This guide will guide you through the complete process from preliminary evaluation to device configuration, helping enterprises quickly achieve network upgrades.

1. Requirement assessment and scheme design

Before formally applying, it is recommended to conduct a "survey" of the existing network and clarify the core business requirements. Firstly, it is necessary to sort out the distribution of nodes and confirm the geographical locations of headquarters, branch offices, and cloud resources; Secondly, it is necessary to prioritize business, such as listing applications with high real-time requirements such as ERP systems and video conferencing as high priority, while setting normal web browsing as best effort. At the same time, the peak bandwidth and latency baseline should be evaluated, and a 20% -30% margin should be reserved for critical business.

At the architecture design level, it is recommended to adopt a hybrid link strategy to balance cost and performance. You can choose high-quality business broadband as the main link to ensure daily critical business, supplemented by regular broadband for load sharing, and configure 4G/5G wireless links as emergency backup. This combination typically saves 40% -60% of link costs. For topology structures, if branches only access headquarters resources, star topology is the most convenient; If there is frequent interaction between branches, it is recommended to use a partial mesh or full mesh topology.

2. Business application and activation process

China Unicom's SD-WAN products support full online self-service, significantly reducing delivery cycles. Users can initiate applications through the China Unicom Government Enterprise Online Portal or by contacting customer managers. Thanks to pre connection technology and SDN automation orchestration, the traditional dedicated line's opening cycle of 30-45 days has been compressed to 1-2 days, and some standard scenarios can even achieve minute level effectiveness.

In the application process, you can customize the purchase cycle according to business fluctuations, and in subsequent use, you can change the bandwidth or dynamically upgrade through the platform to truly achieve on-demand payment. In addition, the China Unicom SD-WAN control platform supports unified orchestration of controllers from various vendors, enabling automated configuration and distribution of forwarding devices, greatly reducing the complexity of manual operation and maintenance.

3. Terminal deployment and zero contact configuration

Hardware selection should be matched based on site size: headquarters or data centers recommend deploying high-end CPE with 10Gbps or more, medium-sized branches should use mid-range devices with 1-5Gbps, and small stores can use entry-level gateways.

During the deployment phase, it is recommended to use ZTP (Zero Contact Deployment) mode. Branch site personnel only need to power on the equipment and connect it to the network cable, and the headquarters administrator can enter the equipment serial number or scan the QR code on the cloud controller. The system will automatically issue configuration files and establish encrypted tunnels, and the entire online process only takes 5-10 minutes at the fastest, truly achieving "zero operation and maintenance" of branch sites.

4. Strategy configuration and operation optimization

After network connectivity, refined strategy configuration is the key to ensuring user experience. Administrators should set intelligent routing strategies in SD-WAN rules, such as specifying video conferencing traffic to automatically lower latency paths and switching large file transfers to high bandwidth links. Shigeng Communication combines Internet Service Database (ISDB) and Application Control Feature Library to achieve precise routing based on the application layer.

In daily operation and maintenance, it is recommended to make full use of visual monitoring dashboards to monitor link latency, packet loss rate, and tunnel status in real time. Regularly use tools such as iPerf for stress testing and fine tune QoS parameters based on actual traffic models. At the same time, actively carry out fault drills to verify whether the switching of primary and backup links can achieve millisecond level response, ensuring that business can still be continuously available in case of sudden network abnormalities.
