Title : CoAP Simple Congestion Control/Advanced

Filename : draft-ietf-core-cocoa-03.txt
Pages : 18

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.
