- Synchronization of TCP Flows in Networks With Small DropTail Buffers
- 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....
