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 *** 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 *** outline the algorithms to calculate the trust value of the trusted-router and the IP *** also introduce the trust-based QoS management algorithm and the deployment of the trusted-routers which carry out this *** simulation results show that the least trusted IP packets will be dropped to save resources for those highly trusted IP *** will ecourage all the elements in the network to keep a good trust record.
