👻Debunking SD-WAN Myths | Are Time-Delayed Session Failovers Sufficient?⛔

Lets admit it, applications and services are not the resilient. You have to step through multiple screens and when the connections drops somewhere before you have finished you have to go back. Much like a networking version of the game of snakes and ladders. The couple of minutes can easily result in rework of 20 minutes.

However, corruption of data can have the adverse impact of a couple of days worth of downtime. Imagine having to close your shop, restaurant or fuel station down because a link failure corrupted your data?

Another problem is that of voice. Session based failovers result in dropped calls. This is debilitating and the goto solution for the significant majority of firewall based solutions.

Any serious network failover cannot rely on session based failover so this myth is well and truly busted. The secret sauce is per packet based load balancing using a hub and spoke architecture.

Watch the video below that explains it well (and Fusion Broadband South Africa uses similar techniques):
