%X A rate-based enhanced adaptive virtual queue(EAVQ) algorithm is proposed, in which the concepts of the principal and subordinate measures of congestion, as well as the desired link-utilization ratio are introduced. The input-rate of network link is considered the principal measure of congestion to hold the advantages of fast dynamic response, short queue delay time, and high link-utilization in adaptive virtual queue(AVQ). Meanwhile, the desired link-utilization ratio is used as the subordinate measure, for which a rate-based adaptive system is designed to solve the AVQ-related problems, such as parameter adjusting, disturbance rejection, and link-capacity loss. The EAVQ algorithm improves the transient performance of the system and ensures the entire utilization of link capacity. Based on the linearization, the local stability conditions of the TCP/EAVQ system in the general network structure are also given. Simulation results show the excellent performances of EAVQ.
