Software-Defined Wide Area Networking (SD-WAN) is transforming branch WAN connectivity by simplifying infrastructure, automating processes, improving application reliability and performance – while lowering costs.
SD-WAN accomplishes this by abstracting network hardware and transport properties from applications, while enabling greater control of app delivery to better meet business needs.
SD-WAN uses software defined abstractions to build a network overlay that decouples network services from the underlying hardware.
Branch WAN Challenges
Many network and application issues can disrupt branch network connectivity:
