TCP Flow Control Based on an Instantaneous Model

Tags:
tcp - ip

Overview With TCP the network congestion is controlled by adjusting the transmission rate through congestion window (cwnd). The cwnd either increases or decreases depending on ACKs (Acknowledgements) which reflect the status of link's buffer queues. This TCP dynamics has been modelled mathematically with various queue management principle of the link. However, the existing results are mostly average dynamic models. But, the authors raise a question about the validity of existing average models. The dynamics of TCP can be modelled by switching between the two sub-dynamic models: dynamics of congestion avoidance and dynamics of fast recovery. The existing average model would be valid only if one parameter groups of the vector fields for two sub-dynamic models commute.
