Abstract: An apparatus calculates, from information included in a packet, a first value that is used to select a path through which the packet is to be transmitted to a destination apparatus. When the packet is a detection packet used to detect a fault in a communication path to the destination apparatus, the apparatus obtains a second value by performing calculation on the first value and a variable value that is changed each time the detection packet is transmitted, and adds an outer header including the second value to the packet. The apparatus adds an outer header including the first value to the packet when the packet is not a detection packet. The apparatus transmit the packet to which the outer header has been added, to the destination apparatus.

Abstract: To provide a switch device and a control method of the switch device which reduce a burden on a manager in an FCoE communication. A switch device relays the FCoE communication between a storage and a server disposed in an internal network and a FCF disposed in an external network. A reception port receives, from the FCoE, information of an external VLAN in the external network in response to a transmission request for information of a virtual network used in the FCoE communication. A protocol processing unit selects an internal VLAN, corresponding to the external VLAN, in the internal network. A transmission port notifies an end node of information of the internal VLAN as information of the VLAN used in the FCoE communication. A packet processing unit relays the FCoE communication between the end node and the FCF based on the internal VLAN and the external VLAN.
