Abstract:
An information processing apparatus includes a first memory, a second memory, and a control circuit. The first memory stores a first table where entries, which indicate forwarding methods for packets, are stored at positions corresponding to hash values calculated from header information of the packets. The second memory stores a second table that is larger than the first table. The control circuit detects, when the first table is updated, a conflict state where there is conflict between storage positions of different entries in the first table. The control circuit moves entries stored in the first table to the second table in response to the detecting of the conflict state. The control circuit detects resolution of the conflict state when the second table is updated. In response to the detecting of the resolution, the control circuit moves the entries stored in the second table to the first table.
