SHAO Wei, ZHANG Yao-xue, CHEN Hua. The Design and Implementation of IPhone System Based on QoS Control[J]. Acta Electronica Sinica, 2000, 28(9): 5-9.DOI:
We propose a QoS (quality of service) control mechanism which is end-to-end to improve quality of voice in IPhone system.This control system creates/maintains the flow states for time-sensitive voice streams to reserve the network resources and guarantees the statistical traffic characteristics through the virtual round robin algorithm during data transmission according to the result of admission control.This paper firstly describes the architecture of QoS control system
secondly gives the admission control algorithm and traffic control algorithm
finally discusses the effect of QoS control according the analysis of the test data.
