Abstract: An information processing apparatus includes a processor that obtains a flow table from a switch apparatus that processes packets by using the flow table. The processor creates, for each flow registered with the flow table, a verification packet based on identification information that identifies each flow. The processor determines a number of verification packets based on a count value that represents a number of actual packets that have arrived at the switch apparatus. The processor generates the number of verification packets for each flow by copying the verification packet created for each flow. The processor determines transmission order of the generated verification packets based on the count value for each flow and time information that represents a time when a final actual packet of each flow has arrived at the switch apparatus.

Abstract: A managing unit adds update information to an entry to be updated of a table updated prior to a change of a network configuration, and deletes the update information when the update of the table caused by the change of the network configuration is completed. A packet processing unit executes a plurality of pipeline processes using the table sequentially, and suspends executing the pipeline processes when the update information is added to any entry of the table. A reprocessing control unit stores an input packet in a reprocessing queue when the pipeline processes executed by the packet processing unit is suspended, and transfers the packet stored in the reprocessing queue to the input queue when update of the table to which the update information is added is all completed.

Abstract: A server detects an abnormality of a VM being a transfer destination of a packet; rewrites, when the VM is switched, a first relationship between a transfer destination MAC address and a port number of the VM before switching to a first relationship between the MAC address and a port number of the switched VM; decides, from the port number being matched based on the rewritten first relationship and a second relationship among a port number of the switched VM, a transfer destination MAC address, and a transfer destination IP address, the transfer destination MAC address and the transfer destination IP address of the switched VM; rewrites the transfer destination MAC address and the transfer destination IP address included in the header of the packet received from a network to the decided MAC address and the IP address; and transfers the rewritten packet to the switched VM.
