We study the behavior of a communication link that divides its capacity fairly among file transfers and streaming flows. We identify appropriate asymptotic regimes and obtain fluid and diffusion limits. The non-trivial, yet tractable, limits can be used for performance analysis and policy design. Furthermore, the scalings used to obtain these limits are themselves of interest and help explain phenomena observed in previous simulation studies.
