Software-Defined Wide Area Network (SD-WAN)
Save
Software-Defined Wide Area Network (SD-WAN) is a virtualized network architecture that allows enterprises to connect their branch offices and remote sites to their central network over the public internet. SD-WAN simplifies network management, reduces costs, and improves performance by decoupling the network control plane from the data plane. This allows enterprises to use any type of underlying transport, including broadband, MPLS, and LTE, to connect their sites.
Benefits of SD-WAN
SD-WAN offers a number of benefits over traditional WAN architectures, including:
- Reduced costs: SD-WAN can reduce costs by up to 50% by eliminating the need for expensive leased lines and MPLS circuits.
- Improved performance: SD-WAN can improve performance by up to 50% by optimizing traffic flow and reducing latency.
- Increased flexibility: SD-WAN gives enterprises the flexibility to connect their sites using any type of underlying transport, including broadband, MPLS, and LTE.
- Improved security: SD-WAN can improve security by encrypting traffic and implementing firewalls and intrusion detection systems.
How SD-WAN Works
SD-WAN works by decoupling the network control plane from the data plane. The control plane is responsible for managing the network and making decisions about how to route traffic. The data plane is responsible for transmitting data between sites. This decoupling allows enterprises to use any type of underlying transport to connect their sites, and it also allows them to manage their network more easily.
