The basic purpose of QoS management is to provide differentiated services and quality guarantee for users. Then how to evaluate the services provided by the system is very important. In the paper, a multi-level QoS management and evaluation architecture for network services is proposed, which supported adjustable selection and reconfiguration of QoS evaluation indexes. With the number of evaluation indexes increasing, eliminating the correlation between indexes is a key issue before QoS evaluation. Reference to Dijkstra shortest path algorithm, a dynamic index reduction algorithm is proposed. To eliminate the correlation of synthetic indexes is to get a set of indexes which the correlation degree is minimum. Examples show that the more indexes, the more efficient the dynamic algorithm can be.
