Solution Overview

The WAN network is primarily responsible for connectivity between different network sites, such as headquarters and branches, branch and branch, DC and DC, etc., and most of that is "passive" and bearing the application flow, but with the development of the application mode, such as cloud computing, mobile and applications, the flow method has changed. The network primarily needs to remain "active" to adapt to changes in application modes, to provide varied services for different applications. However, the current network management is primarily for devices rather than businesses and that makes the network architecture so complex, difficult to extend, unable to adapt to WAN network development.

AD-WAN (Application Driven - Wide Area Network) is a standard SDN network architecture. It is a hierarchical, open and flexible architecture, with the characteristics of intelligent traffic steering, business visualization, high reliability etc. Reduce network cost and O&M difficulty for customers.

H3C AD-WAN Architecture

Features and Benefit

Automation

Zero Touch Provision (ZTP)

The AD-WAN solution provides multiple automated deployment methods, which provide unified deployment and O&M for automatically deployment devices, reducing the difficultly of O&M and manpower cost. The currently supported zero-configuration deployment includes the following methods:

USB Driver:

Branch device automatically reads the configuration information in USB driver after powered on, and registers with the controller.

URL:

The administrator enters the branch site location and device information on the controller in advance, and send the URL link to branch site with email. The branch device is configured according to the configuration parameters in the URL and establishes a connection with the controller.

VPN Fast Deployment

Compared with traditional manual VPN deployment, AD-WAN supports graphical VPN service deployment. Users only need to select the start and end points of the tunnel to automatically build the VxLAN tunnel.

WAN-LAN Convergence

AD-WAN solution supports automatic LAN deployment. For LAN side network, if a branch needs to separate different departments according to VLAN, such as finance, R & D, and marketing department.AD-WAN supports automatic DHCP pool configuration and routing configuration.

Easy QoS

AD-WAN provides one-click deployment of QoS, to meet the differential application requirement. Cooperate with the intelligent traffic scheduling function to ensure the quality of high-priority business and improve user experience

Intelligent Traffic Steering

AD-WAN solution provides multiple steering strategies:

Link Priority: Determine the priority based on the link type. Set link priority policy for different applications, and select the link with high priority first. When the preferred link fails, select the secondary link.

Link Quality: Determine the priority by the link quality. Define the link quality requirements of the application in advance and select the required link for the application. If no link can meet the requirements, the device will choose the link, which is closest to the requirements.

Bandwidth: Define the bandwidth requirement of applications in advance and allocate links based on application demand for bandwidth to improve bandwidth utilization.

Time Period: Different strategies can be implemented according to time period to ensure key business.

High Reliability

AD-WAN solution provides high reliability, including control plane reliability, end-to-end reliability and link reliability. Reduce the risk and reduce unnecessary loss for customers.
