Abstract
A system and method for adaptive encryption for SD-WAN includes identifying an encrypted conversational flow and determining whether a duration of the encrypted conversational flow exceeds a threshold. The method also includes selecting a header-less tunnel for the encrypted conversational flow when the duration is more than the threshold. The method further includes transmitting the encrypted conversational flow to an egress router over the selected header-less tunnel.
