AD - WAN: Revolutionizing Wide Area Network Management

What is AD - WAN

The AD - WAN (Application - driven Wide Area Network) solution represents a cutting - edge, converged, layered, open, and intelligent network technology architecture. It integrates intelligent management, control, and analysis modules, achieving a three - dimensional integration of "management," "control," and "analysis." Moreover, it offers users a unified portal, enabling "one - time login, one - click issuance, integrated guarantee, and one - stop operation and maintenance." By combining big data analysis with AI learning capabilities, the AD - WAN solution can capture real - time network snapshots, perform offline modeling, and realize intelligent network prediction and troubleshooting.

The Need for AD - WAN Hosting

The WAN is crucial for the remote interconnection and communication of different network sites, including headquarters and branches, branches and branches, and data center interconnection. While the traditional WAN has passively "carried" business traffic, the evolution of application modes such as cloud computing and mobile Internet, along with changing traffic patterns, demands that the network actively "adapt" to business traffic and change as needed. Traditional network management, which is mainly equipment - oriented and lacks active operation and maintenance capabilities based on a business perspective, leads to complex network services, difficult upgrades and expansions, and a closed, rigid architecture. Modern WAN management requires a greater focus on business scheduling and tuning from a global perspective, rather than just the performance and operation of a single network node.

H3C, with its accumulated technology and experience in the WAN field, has developed a new - generation WAN solution - the AD - WAN solution - targeting the actual application problems and needs of users. This solution is designed to help users build an open, flexibly programmable, and easy - to - operate WAN to carry increasingly rich application traffic. Through it, applications can drive the network, and the network can dynamically adapt to applications.

What Does AD - WAN Include?

Business Simplicity

VPN Service Delivery: The AD - WAN solution supports one - click automatic delivery of VPN services. Users only need to specify the service deployment scope on the operation interface, and the service configuration will be automatically delivered to network element devices. This reduces the workload and operation and maintenance risks associated with manual configuration, achieving a quick deployment experience in just minutes.

One - click QoS Delivery

End - to - end QoS services are automatically issued to achieve traffic speed limiting and application assurance based on user services. The AD - WAN solution solves the problem of insufficient assurance capabilities in traditional networks, which relied on single - device QoS deployment, by leveraging its end - to - end QoS assurance function for applications. It enables rapid and batch delivery of service QoS configuration. When deploying QoS, users can either issue it to the entire network with one click based on a global template configuration or select local template deployment for a single link, offering greater flexibility.

Business Strategy Issuance

The AD - WAN solution supports refined business matching and automatically issues policies on bandwidth, quality, time period, bandwidth calendar, etc. It can also dynamically adjust business policies according to the real - time status of the network to ensure reliable and stable operation of the business.

Flexible Protection

• Traffic Load Balancing: The AD - WAN solution uses SRv6 TE Policy to implement multi - path load balancing for service traffic. Administrators can specify weights to define the load - sharing ratio, and AD - WAN also supports automatic calculation of weights based on the remaining bandwidth resources of the path.
• Network Traffic Optimization: The AD - WAN solution provides two key network capabilities based on single - application path tuning and full - network service tuning. It avoids forwarding deadlock in extreme cases when the network is congested, improving the resource utilization and risk - resistance capabilities of the entire network.
• Key Business Protection: The AD - WAN solution offers a rich set of traffic scheduling strategies. It supports path calculation based on bandwidth, latency, jitter, packet loss rate, time period, preferred links, excluded links, optional links, and other strategies. By performing flexible link switching for services, it ensures the user's service experience.

Intelligent Operation and Maintenance

• Multidimensional Visualization: The AD - WAN solution provides a large - screen visualization function, displaying link status, link bandwidth and quality, device status, application bandwidth and flow, node information, real - time alarms, map topology, etc. Users can easily grasp the real - time status of the current network and resources. It also supports customized large - screen visualization presentations on demand.
• Prediction Simulation: The AD - WAN solution supports intelligent analysis and can collect performance data such as device interfaces and links through Telemetry. It can actively monitor and predict network anomalies, outputting prediction results to help users understand the trend of network status changes, avoid failures, and prevent problems before they occur.
• Fast Fault Location: The AD - WAN solution supports application network transmission quality collection, including new application data flow collection technologies such as iFIT, to meet the needs of application traffic visualization and application quality analysis. Using iFIT, it implements end - to - end detection based on the service flow level to quickly delimit network faults. Based on point - by - point detection at the service flow level, it can quickly locate the fault point. Through more comprehensive, more detailed, and more real - time network equipment measurement data, the operating status, faults, and risks of the network equipment system plane, control plane, and data forwarding plane can be directly analyzed, achieving white - box diagnosis and analysis of the network.
