Business locations across the world rely on connectivity to share critical company information. Software-defined WAN (SD-WAN) is an emerging technology that is gaining momentum with retailers. This solution creates a more resilient network by leveraging the most cost-effective and bandwidth-rich WAN connections allowing for improved network performance.
What is SD-WAN?
SD-WAN is an approach to designing and deploying an enterprise wide area network (WAN) that uses software-defined networking (SDN) to determine the most effective way to route traffic to remote locations. SD-WAN can be used to manage multiple types of connections - from MPLS to broadband to LTE - allowing it to be extremely versatile for company adaptation.
This technology allows the user to aggregate several different connections and have them function as one virtual overlay network that is transport-agnostic. By using any combination of connections available to an organization, businesses with branch offices, in any geographic area, are able to receive great connectivity and continuity.
Seamless Failover of Applications
SD-WAN can also provide seamless failover of applications allowing your day to day to be free of interruptions or outages. This solution avoids carrier last mile disruptions. Optional packet duplication ensures best possible performance for real-time traffic. Seamless failover for mission critical applications means essentially always being up and avoiding unnecessary downtime.
SD-WAN is redefining the traditional, costly WAN model. Increasing bandwidth at branch locations can be expensive and time consuming. SD-WAN can be composed of any combination of; 3G/4G LTE, MPLS, Internet, Ethernet, or Serial service allowing for quick installation and increased bandwidth options. By utilizing all the available resources, including inexpensive Internet services, SD-WAN dynamically selects from a more cost-efficient assortment of public Internet connections and private links. Organizations no longer need to continuously upgrade their bandwidth to ensure a reliable connection with SD-WAN.
Gartner estimates that although SD-WAN has less than 1% market share today, up to 30% of users will be managing their WAN through software within three years. SD-WAN allows organizations to expand their network capabilities without jeopardizing their connection, spending more than they need to on expensive bandwidth, or complicating their existing network infrastructure. Keep your multi-site organization connected with Software-Defined WAN.
