Failsafe Network/Failsafe WAN
A failsafe network is a network that delivers both high availability and reliable, predictable application performance (a.k.a. Quality of Experience, or QoE). Usually used in the context of a wide area Network (WAN), where delivering consistent QoE is not always easy to do, especially when Internet connections are involved.
Value of Failsafe Network/Failsafe WAN
Failsafe WANs means both high network availability and reliable, predictable application QoE. Given the high cost of downtime, limited IT resources available at most remote locations, and limited enterprise visibility into the WAN, even the most aggressive, leading-edge enterprises want failsafe WANs if they are going to augment or replace their time-tested MPLS-based solution. Unaided Internet connections merely work pretty well most of the time, and that’s not good enough for most enterprise WAN Managers of CIOs. The tantalizing benefits the cloud and SD-WANs offer notwithstanding, enterprise IT folks disdain “two steps forward, one step back” solutions for good reason.
Examples of Failsafe WANs are MPLS, or SD-WANs from vendors like Talari Networks that have the right set of Failsafe Technologies to “tame” a set of otherwise insufficiently reliable and predictable Internet connections.
