    abstract =  {This document specifies an alternative retransmission timeout and congestion control back off algorithm for the CoAP protocol, called Fast-Slow RTO (FASOR). The algorithm specified in this document employs an appropriate and large enough back off of Retransmission Timeout (RTO) as the major congestion control mechanism to allow acquiring unambiguous RTT samples with high probability and to prevent building a persistent queue when retransmitting. The algorithm also aims to retransmit quickly using an accurately managed retransmission timeout when link- errors are occuring, basing RTO calculation on unambiguous round-trip time (RTT) samples.},
