Research firm, Gartner, says: SD-WAN solutions employ centrally managed WAN edge devices placed into remote offices to establish logical connections with other branch edge devices across the physical WAN. These connections create secure paths across multiple WAN connections and carriers.
In simpler terms, SD-WAN is like the Waze (driving directions) app. Like SD-WAN, Waze finds the optimal route to your destination based on factors that affect your commute (traffic, construction, etc.). SD-WAN is no different; it finds the optimal link for your packets to traverse (based on factors like latency, jitter, etc.) to ensure packet delivery and routing for application at hand.
SD-WAN will significantly improve your connection speed and quality for voice, video and text based applications.
ADVANTAGES FOR SD-WAN
One Network from Multiple Carriers: With SD-WAN there may be multiple network carriers used across multiple locations. Allowing network changes to be made much easier.
Performance Monitoring: A SD-WAN’s single console and uniform software deployment makes it possible to monitor network and application performance at any point in the network.
Location Agility: Enable multiple links, devices and services to coexist and interoperate. With the use of software to make the network function, it becomes easier and faster to turn on new endpoints or change locations.
Balance Costs: With greater carrier choice and uniform hardware, SD-WAN evens out the cost differences between locations.
- Replace high cost MPLS/private bandwidth with low cost internet connections.
- Respond in real time to network performance and route around issues.
- Easy to deploy and maintain.
- MPLS-like performance of real-time and important applications (QOS).
- Application level analytics.
