摘要：
In order to estimate the reliability performance of multicast communication under multiple constraint conditions, the weight of service rate and the reliability index are defined, accompanying the calculation method. Firstly, according to the Quality of Service requirements, the appropriate routings between the central node and target nodes that meet the requirements are calculated using the iterative method in the weighted internet. Then, the disjoint set of network state and the coefficients of weighted service rate are calculated by decomposition and merge methods. Lastly, the formula for calculating the service rate is obtained based on the disjoint set of network state and the calculation of the reliability index will be completed. The simulation result shows that the reliability of multicast communication can be appropriately reflected by the weight of service rate and the calculation method, which can provide the theoretical basis for the reliability evaluation of multicast communication.
