摘要：
A quality of Service (QoS) mapping problem arises when different encapsulation formats are employed to support the QoS over different transport technologies. For example when IP packets are transferred over ATM or MPLS core networks. The paper faces this problem in terms of bandwidth management, by investigating the sensitivity Of bandwidth needs due to the change of encapsulation format. We study a novel control algorithm to estimate the bandwidth shift required to keep the same performance guarantees, independently of the technology change. The proposed algorithm is based on the Infinitesimal Perturbation Analysis, which is a sensitivity estimation technique for Discrete Event Systems. Simulation results concern a comparison with an heuristic much used in industrial applications as well as some experimental tests concerning Voice over IP to highlight the fast convergence of the algrorithm in variable system conditions.
