Bidirectional Forwarding Detection (BFD), as described in [RFC5880] and related documents, has efficiently generalized the failure detection mechanism for multiple protocols and applications. There are some improvements that can be made to better fit existing technologies. There is a possibility of evolving BFD to better fit new technologies. This document focuses on several aspects of BFD in order to further improve efficiency, expand failure detection coverage, and allow BFD usage for wider scenarios. Additional use cases are listed in [RFC7882].

           Seamless Bidirectional Forwarding Detection (S-BFD)


   This document defines Seamless Bidirectional Forwarding Detection    (S-BFD), a simplified mechanism for using BFD with a large proportion    of negotiation aspects eliminated, thus providing benefits such as    quick provisioning, as well as improved control and flexibility for    network nodes initiating path monitoring.

   This document updates RFC 5880.
