  "abstract_en": "This document describes an experimental optimization to Bidirectional Forwarding Detection (BFD) Authentication. This optimization enables BFD to scale better when there is a desire to use authentication where applying the same authentication mechanism to every BFD Control Packet may adversely impact performance. This optimization partitions BFD Authentication into a more computationally intensive (MCI) mechanism that is applied to BFD significant changes and a less computationally intensive (LCI) mechanism that is applied to the majority of BFD Control Packets.",
