SD-WAN simplifies management and operation of WAN by separating network hardware from its control mechanism. SD-WAN gives companies the option to dynamically connect branch and head office networks, for example, by utilizing shared Internet and cloud capabilities. There are many benefits of SD-WAN products being able to help network in your business become more practical than using traditional WAN. Here are 5 things about SD-WAN that you need to know about.
The most noticeable difference between SD-WAN and traditional WAN is performance improvement. On a WAN, failover time depends on how fast the routing changes on the router. Routing changes on a router last an average of 3 minutes. SD-WAN itself offers faster failover, only takes 1 second so that it provides improved performance compared to traditional WAN.
Using a traditional WAN when a company creates a new network at a branch office will take time. Although in general the duration is almost the same, SD-WAN network products installation can be done faster thanks to Zero Touch Provision technology. Failover time when there is a move from one link to another becomes almost imperceptible with the support of Link Steering / Dynamic Multipath Optimization (DMPO) technology.
Traditional WAN is very dependent on the data center. This requires that network traffic be backed up through the data center so that it can be blocked. Meanwhile SD-WAN has a collection of integrated bandwidth provided by several service providers. This allows greater utilization of network resources when data migrates across offices.
Data centers that are the foundation of traditional WANs have limited capacity. Specifically to handle connections that enter multiple cloud platforms. This will not happen on SD-WAN because it is not limited to hardware that accommodates the network.
The configuration policy for traditional WAN supporting devices must be carried out independently, according to a per device basis. This is done so that the configuration can be applied properly. In SD-WAN, WAN applications are prioritized as a whole. Besides, companies can monitor traffic in real-time when brownouts occur.
Based on the explanation above, it can be concluded that the software approach by utilizing the capabilities of the Internet and the cloud cannot be done by traditional networks. Also, SD-WAN promises flexibility, security, and cuts network complexity.
