Modeling TCP/RED: A Dynamical Approach
Overview Interaction between Transmission Control Protocol (TCP) and Random Early Detection (RED) gateways can be captured using dynamical models. The communication network is viewed as a discrete-time feedback control system where TCP adjusts its window size depending on whether or not it has detected a packet loss during the previous Round Trip Time (RTT) interval. This paper describes a discrete-time nonlinear dynamical model for interaction between TCP and RED gateways. The model, constructed using an iterative map, captures a detailed dynamical behavior of TCP/RED, including slow start, fast retransmit, and timeout events common in TCP. Model performance for various RED parameters is evaluated using ns-2 network simulator.
