What’s SD-WAN
SD-WAN (Software-defined WAN), through the use of virtualization technology, application-level policies and overlay networks, achieve two purposes:
1. Comprehensively utilize multiple shared or private links to enable common links to achieve dedicated line network quality, reduce traffic costs, and increase bandwidth.
2. According to the current network situation and the configured policy, the optimal path is automatically selected to achieve load balancing and ensure network quality.
Control plane
Data level
High transmission quality
Intelligent dynamic routing automatically selects the best transmission path according to transmission requirements, and has WAN optimization, which can repair WAN packet loss
Critical application protection
Protect critical applications by setting policies to ensure that they can obtain sufficient bandwidth and meet SLAs
More secure access
use AES-256 combined with asymmetric key algorithm to encrypt control and business traffic, and have corporate firewall, IPS, URL filtering, and DNS monitoring functions to ensure that services are not attacked
Short provisioning cycle and rapid deployment
Connect each node through the Internet or 5G, and combine ZTP technology to achieve second-level provisioning
WAN autonomous and controllable
Through traffic engineering and network segmentation technology, users can organize the WAN architecture more quickly and autonomously
Centralized management of intelligent operation and maintenance
intelligent dynamic routing and routing automatically selects the best transmission path according to transmission needs
Flexible expansion
rapid expansion of new nodes, no need to configure node by node
Save corporate costs
Save WAN leased line costs and O & M costs
One-click cloud
support mobile cloud, AWS, Azure, break the traditional way to connect to the cloud
