摘      要：This paper presents a scheme to perform QoS management and assure network security by using the trustedrouter based on the Trust Management System. In this trustedrouter, every IP packet is forwarded and queued by its trust value, which is the quantification of the networks expectation for this packets and its owners behavior in the network. We outline the algorithms to calculate the trust value of the trustedrouter and the IP packet. We also introduce the trustbased QoS management algorithm and the deployment of the trustedrouters which carry out this algorithm. The simulation results show that the least trusted IP packets will be dropped to save resources for those highly trusted IP packets. This will ecourage all the elements in the network to keep a good trust record.
