Resilient and efficient multipoint mechanisms are required in optical networks. In this study, we propose a risk-sharing primary tree selection algorithm to enhance the redundant tree recovery method in multipoint optical networks. The mechanism not only can ensure the minimum hop distance from the source to every destination, but also can make nodes in the network share the risk of failure and degradation by averaging the number of messages triggered. Simulations demonstrate that the proposed mechanism ensures a better network environment after failure or degradation of multipoint optical networks.
