Path controller, path control method, and program therefor |
摘要 |
To provide a path controller capable of reducing path search time. A path controller 10 creates a logical tree LT having a plurality of member trees MT1 and MT2 within a routing table 52 at the time of initial setting. Direct tables DT1 and DT2 for the member trees MT1 and MT2 have 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 SE1 and SE2 search the member trees MT1 and MT2, respectively.
