One of the most common reasons for moving to a Software-Defined Wide Area Network (SD-WAN) is its vastly more flexible, scalable and adaptable nature, as compared with the fixed, immutable nature of the traditional WAN built on leased lines and MPLS.

At the same time, though, this fixed, immutable nature can make moving away from the older technologies a difficult process, fraught with expense, contractual issues and logistical complexity.

This difficulty is one of the principal reasons these fixed circuit technologies tend to remain in play for significant periods of time, often long after they have ceased to be the best option, and despite the significant operational and financial benefits of SD-WAN. Unsurprisingly, incumbent providers exploit this inertia, enjoying the recurring revenues as they roll in, year after year.
