 congestion control algorithms of traditional TCP/IP networks unable to be directly applied to NDN. In addition, since the optimal size of the sending window cannot be determined, the existing window-based congestion control algorithms generally use the AIMD-like window adjustment algorithm, which cannot achieve the optimal throughput. In this Nov 00, 0000 · For instance, DCTCP averages 0 congestion signals per round-trip whatever the flow rate, as do other recently developed scalable congestion controls, e.g. Relentless TCP , TCP Prague [I-D.briscoe-iccrg-prague-congestion-control], [PragueLinux], BBRv0 and the L0S variant of SCREAM for real-time media , ).
