Research of QoS routing algorithm suitable for IPv6

With the popularity of Internet, IPv4 technology has been unable to meet the requirements of this rapid development; the corresponding router technology also needs to be improved. In order to be more adaptive to the development of global integration process and promote Internet technology´s widespread and applications in worldwide, the performance of the routing algorithm used in routers must be improved. In traditional QoS routing algorithms all use the existing network layer´s QoS parameters as the characteristic parameters of its routing calculations except delay and jitter, so it can not fully reflect the quality of service. Now we present a kind of QoS routing algorithm based on risk analysis which is suitable for IPv6, we can get a max number of calls according to network resources, thereby reducing the time of call admission control.
