PROBLEM TO BE SOLVED: To output multicast routing where no branch takes place for a unicast transmission apparatus while reducing a link cost from a transmission side transmitter to each reception side apparatus even in a communication network where multicast transmission apparatuses and unicast transmission apparatuses intermingly exist.;SOLUTION: When a transmitter or relay node is a unicast transmission apparatus in the calculation of multicast routing, priority is placed on a candidate apparatus and transmission apparatuses adjacent to the candidate apparatus except the searched adjacent apparatuses by using conditions such as the number of physical links, multicast transmission capability and a link cost or the like, and a succeeding transmission apparatus is determined and searched on the basis of the priority.;COPYRIGHT: (C)2006,JPO&NCIPI
