To provide better QoS management, we investigated network-level dynamic priority methods. We propose methods in which packets of the same type of application receive different treatment in the network, depending on the route information. They feature a simple mechanism, which enables the methods to be executed easily with a small processing load at the routers as well as a small amount of information stored in the packet header. The effectiveness of these methods is shown by numerical comparison with the existing static priority method as well as the dynamic priority method.
