Top 10 Things you Should Know About SD-WAN
Software-defined wide area networking (SD-WAN) is a way of connecting remote sites, regional locations, and data centers over a wide area network (WAN).
Traditional WANs use packet routers to connect these locations to one or more public or private service provider networks. Routing protocols then dictate how application traffic is routed over these networks to reach the intended destinations.
So, what is SD-WAN? SD-WAN is considered an evolution of traditional WAN and offers the following benefits:
- Traditional WAN typically requires configuration and management of complex VPN tunnels. SD-WAN automates this process
- Traditional WAN has issues mixing different WAN circuit types in the same location. SD-WAN allows you to mix these (i.e. MPLS and broadband)
- Traditional WAN relies on complicated routing protocols. SD-WAN does not
- Traditional WAN often requires configuration of each device separately. SD-WAN generally uses a common, centralized controller for configuration
Businesses migrate from a traditional WAN to SD-WAN to:
- Leverage broadband for better performance and lower cost than MPLS
- Improve high availability in the branch office
- Integrate cloud applications into their workforce
- Simplify IT operations by moving to a top-down policy model
- Reduce branch office cost including hardware, management, and maintenance
