Synchronization of TCP Flows in Networks With Small DropTail Buffers
Overview A recent fluid-model formulation of an Internet congestion-control problem considers routers with small Droptail buffers. This paper is interested in the oscillatory regime of such networks and considers a topology where two TCP-controlled flows (each regulated by separate (edge) routers) merge to compete for bandwidth at a common (core) router. This paper describes this dynamic using a weakly-coupled oscillator model and analyzes the coherence of oscillation as a function of coupling strength. The paper shows that increased coupling leads to increased coherence and to larger variations in the arrival flow at the core router. The coupling strength can be expressed in terms of network parameters.
