SD-WAN Practice
The best practice for SD-WAN design requires new logic leveraged for what seems to be an old task. With legacy WAN projects, the greatest network engineers and architects spent months planning every detail, which resulted in a forced compliance model for success. PBR enforced behaviors for traffic across the network to attempt to guarantee performance. With SD-WAN, any forced behavior will lead to failure, as the software continually evolves every few weeks. Network conditions are always changing, which caused the legacy design to consider every lesson learned to that point. The point of software-defined networking is that all possible conditions cannot be known, therefore, the software has to be dynamic and somewhat autonomous in the way it self-heals and self-tunes.
Best practice rules for success are as follows:
- First rule: Keep the design as simple as possible. The SD-WAN edge device gets an MVP configuration that basically connects it to the network...
