Abstract:
   CoAP, the Constrained Application Protocol, needs to be implemented
   in such a way that it does not cause persistent congestion on the
   network it uses.  The CoRE CoAP specification defines basic behavior
   that exhibits low risk of congestion with minimal implementation
   requirements.  It also leaves room for combining the base
   specification with advanced congestion control mechanisms with higher
   performance.

   This specification defines more advanced, but still simple CoRE
   Congestion Control mechanisms, called CoCoA.  The core of these
   mechanisms is a Retransmission TimeOut (RTO) algorithm that makes use
   of Round-Trip Time (RTT) estimates, in contrast with how the RTO is
   determined as per the base CoAP specification (RFC 7252).  The
   mechanisms defined in this document have relatively low complexity,
   yet they improve the default CoAP RTO algorithm.  The design of the
   mechanisms in this specification has made use of input from
   simulations and experiments in real networks.
