ABSTRACT:
A path controller10creates a logical tree LT having a plurality of member trees MT1and MT2within a routing table52at the time of initial setting. Direct tables DT1and DT2for the member trees MT1and MT2have the same DT entries (root). Unlike a conventional tree in which a single tree is constructed for the same root, since the present invention is such that the plurality of member trees are constructed for the same root, the number of nodes N passed through before reaching leaves L is reduced. At the time of path search, a plurality of search engines SE1and SE2search the member trees MT1and MT2, respectively.
