ABSTRACT:
In respective leaf tables (LT(1) to LT(m)) of a coupling management table (20), there are provided delete operation identifiers (D(1) to D(m)) indicating that leaf queues (LQ) respectively next to them toward the upstream direction are under delete operation. When one of the leaf queues (LQ(n)) should be deleted, if the leaf queue (LQ(n)) to be deleted stores any element, the delete operation identifier (D(n+1)) is set to 1. Thereby, the leaf table (LT(n−1)) can acknowledge that the leaf queue (LQ(n)) is currently under delete operation. Therefore, the coupled packet queue after deletion of the leaf queue and the coupling management table can be maintained consistent.
