Enterprises have well realized the fact that static MPLS connections and legacy routers that connected branch offices to business-critical applications, data, and services were a major bottleneck to digital transformation.
Traditional routers could not bond MPLS and Broadband links. You required high-end broadband bonding routers to bond MPLS and several other broadband modems. In case the MPLS link failed, broadband lines carried the internet traffic over the public internet. However, this was one of many limitations.
Traditional routers lacked the ability to scale. Enterprises couldn’t extend networks to new sites and deploying applications and services required on-site configuration. Besides, routers lacked the ability to steer traffic dynamically. Although the traffic was moved to the best path available, routers couldn’t steer the traffic, which ultimately resulted in connection loss. Cost of the hardware (router) and its complicated setup process compelled enterprises to rethink beyond traditional routers.
Enterprises Slowing Down Router investments
Enterprises worldwide are on the verge of replacing traditional routers with SD-WAN. Although this shift has been trending worldwide for quite some time now since the disruption of SD-WAN, Indian enterprises too, are fast catching up with the wave.
“In our discussions with vendors, it has become apparent that most recognize SD-WAN as a mainstream technology,” said IHS Markit analyst Josh Bancroft. “As a result, larger enterprises have begun to refresh their legacy, router-centric WANs with SD-WAN. Vendors are capitalizing on the refresh opportunities with customers that have large bases of aging router equipment.”
