What Is an SD-WAN?
SD-WAN stands for Software-Defined Wide Area Network. It is a technology that abstracts a company's wide area network (WAN) from its hardware infrastructure. Here are the key things to know about SD-WAN:
• It uses software to virtualize a company's WAN and give network administrators more control and flexibility.Chuwi herobook pro
• SD-WAN decouples the network controls and policies from the underlying WAN transport pipes (like MPLS, broadband internet, 4G/LTE, etc.).
• This allows companies to use multiple types of WAN connections simultaneously based on application needs.
• SD-WAN uses overlays to direct traffic across the most optimal connections in real time based on policies.
• It can improve application performance, security and reliability across distributed networks with multiple branches and offices.
• SD-WAN solutions are usually provided by networking vendors as appliances that sit at the edge of a company's network.
• These SD-WAN edge devices connect back to a centralized management console where network admins set policies and orchestrate the SD-WAN.
• Benefits of SD-WAN include lower costs by using lower-cost internet links, improved traffic steering, centralized management and visibility.
In summary, SD-WAN is a newer software-based approach to configuring and managing wide area networks that provides more flexibility, agility and choices for how to deliver applications across distributed networks.
