Abstract：In this paper, the model of limited radius, residual balanced multicast routing problem is improved. Considering the degree-constraints, minimal radius and load balance simultaneously, we present the concepts of deficient degree and the saturate degree of the nodes, and then propose subtle measurements on load balance in the multicast routing from two evaluation models: one is the evaluation model based on the variance of absolute deficient degree; and the other is the evaluation model based on the variance of relative deficient degree. An elaborately designed example manifests that the concepts and models are significant and practical.
