Traditional WAN solutions often have simpler network architectures and fewer components compared to SD-WAN. This can result in faster fault detection as there are fewer potential points of failure and network issues can be more easily identified.
Simplified troubleshooting: With a traditional WAN, the network topology and configuration are typically more straightforward and standardized. This can simplify troubleshooting processes as network administrators can have a clearer understanding of the network design and can more easily identify and resolve issues.
SD-WAN offers benefits such as lower control plane abstraction, comprehensive configuration standardization, and lower data plane overhead.
A traditional WAN might have lower control plane abstraction and lower data plane overhead than an SD-WAN solution.
Traditional WANs typically have a simpler architecture where the control plane (which is responsible for routing decisions) and the data plane (which carries the user data) are not separated. This results in lower control plane abstraction.
Also, since traditional WANs are not overlay networks like SD-WANs, they generally incur less data plane overhead. Overlay networks add extra information (headers) to the original packets, which results in increased overhead and potentially less efficient use of the available bandwidth.
It's important to note that while these may be perceived as benefits in certain cases, the trade-offs include less flexibility, more complex configuration and management, and lack of some features like centralized control, easy scalability, and advanced traffic management that are typically found in SD-WAN solutions.
