Abstract:

With the emergence of a large number of new network applications, traditional network technologies cannot meet the requirements of current applications on bandwidth, latency, error rate and etc. In this case, IP over DWDM optical Internet has become a research hotspot with unique characteristics and advantages. In this paper, we put forward a heterogeneous multicast routing mechanism for IP over DWDM optical Internet based on the species evolutionary algorithm. The scheme employs the theory of probability to solve the uncertainty problem of  networks’state parameters information. We adopt the fuzzy method to support flexible QoS and design a bandwidth pricing method which considers the benefits of both users and network service providers. Simulation results show that the proposed mechanism can achieve good comprehensive performance indexes and effectively solve the QoS heterogeneous multicast routing problem in the IP over DWDM optical Internet.
