Abstract

See full text

An RB includes a grouping unit that groups VLANs in a TRILL network into patterns by using the low 3 bit sequence of a VLANID; a calculating unit that calculates the number of redundant paths with equal costs among physical paths in the TRILL network; and a sorting unit that sorts the patterns of VLANs, which are to be assigned to the physical paths, into the groups that are equivalent to the number of redundant paths according to a predetermined order. The RB includes an assignment table for managing, with respect to each of the groups, an assignable output destination path among the physical paths. The RB includes a control unit that refers to the assignment table, determines the output destination path for each of the groups, and collectively assigns all the VLANs of all the patterns of an appropriate group to the output destination path of the group.
