As the DiffServ architecture is gaining ground, traffic engineering requires major adjustments. In addition, the measurement-based strategy has been widely adopted owing to its advantages of flexibility and easy adaptation. This article reviews measurement-based dropping schemes. Based on the definition and investigation of the "packet shortage" phenomenon, an enhanced dropping scheme for the proportional differentiated packet loss, referred to as "debt-aware," is proposed. Simulation results show that the scheme partially curbs negative effects of "packet shortage" and closely approximates loss differentiation parameters, as compared to a typical proportional dropping mechanism. More simulations have been applied to demonstrate the merits of this improved method.
