Abstract

TCP over bandwidth asymmetric networks such as cable TV, asymmetric digital subscriber loop (ADSL) and wireless networks exhibit different characteristics from TCP on symmetric links. A number of techniques have been proposed to address this problem. However, previous research has been largely focused on bulk transfers. This paper investigates the effects of bandwidth asymmetry on Web-like short-lived transfers. A close-form prediction model is presented for TCP transfers over asymmetric links. The Web transfer model is then derived from it. Simulations based on ns-2 show that the model can give predictions for TCP transfers with a high degree of accuracy
