Abstract: According to the characteristics of the QoS (quality of service) rerouting in trustworthy network, this paper proposes a vaccination immune genetic QoS rerouting scheme. Then, this paper presents the network model, the description of users’ requirements and the calculation methods of users’ satisfaction. In order to resolve the trustworthy problem of QoS routing, this paper establishes a trustworthy evaluation model. On this basis, considering the users’ QoS requirements, the users’ trustworthy requirements and the reuse of links on the original path, this paper also proposes the QoS rerouting algorithm. The simulation results show that the proposed scheme has better performance than existing algorithms, and can satisfy users’ demands with the rerouting success rate and the user satisfaction increased.
