The traditional WAN model used to prioritize traffic in site-to-site connectivity backhauls traffic from branch offices to centralized data centers for security inspection. It caused bandwidth waste, latency and impaired application performance. In addition, MPLS circuits typically used to perform this function were very costly.
SD-WAN (Software Defined Wide Area Network) automates IT traffic over your existing Internet circuits. SD-WAN is programmed to steer specific types of data to its destination with prioritization eliminating the need for MPLS and reducing overall costs.
The benefits:
- Provides consistent app performance
- Automates traffic steering
- Improves security
- Simplifies WAN architecture
What is Wrong with Traditional WAN Architecture
Traditional WAN routers are not designed for the Cloud and traffic backhauls impair app performance. SD-WAN technologies, on the other hand, can support on-premises data centers, Cloud, and SaaS services to enhance app performance.
