Description
Summary:Aiming at the calculation of secure multicast routing in multi-domain optical network, a new secure multicast routing algorithm based on distributed path calculation element was proposed. Firstly, the distributed PCE multicast routing model was constructed, and the intra-domain cost, inter-domain cost, maximum available wavelength and related constraints were defined. Secondly, the pheromone update strategy of ant colony algorithm with ant queen was locally simplified and modified to make it suitable for the distributed PCE architecture of multi-domain optical network. At the same time, by optimizing the trust value calculation method in the lightweight cross domain trust model, the algorithm can be applied to the calculation of trust value of multicast routing in multi domain optical networks. Finally, the specific implementation steps of the algorithm were given. The analysis and experimental results show that the algorithm can not only ensure the security of cross domain multicast routing, but also prevent the malicious nodes from destroying. Compared with the typical multicast routing algorithm, it has better performance in multicast tree cost and blocking rate in malicious node environment.
