Abstract: Network switching arrangements including: setting an operation mode of a target switching block to a operation mode that is different from an operation mode of a first switching block while the first switching block is handling a switching process, the target switching block being one switching block selected from second switching blocks; performing a switchover process including starting the switching process using the target switching block instead of the first switching block, after completion of setting the operation mode of the target switching block; and copying the switching information held by the first switching block to the target switching block, prior to starting the switching process using the target switching block, after completion of setting the operation mode of the target switching block.

Abstract: A packet relay apparatus, which is configured to transmit from a mirror port a mirror packet copied from one of a packet to be received and a packet to be transmitted, the packet relay apparatus comprising: a packet receiving module configured to receive a packet from an input port; a security judgment module configured to judge whether or not the packet is possibly one of an attack and an attack sign; a mirror processing module configured to generate, when it is judged that the packet is possibly one of an attack and an attack sign, a replica of the packet as the mirror packet; and a transmitting module configured to transmit the mirror packet from the mirror port.

Abstract: A communication device: stores flow condition information for identifying a flow and flow counter information that indicates, for each flow, an input flow volume of a flow inputted to the communication device, and an output flow volume of a flow outputted by the communication device; identifies a flow to which data inputted to the communication device belongs, with reference to the flow condition information; updates the input flow volume of the flow in the flow counter information; identifies a flow to which data outputted by the communication device belongs, with reference to the flow condition information; updates the output flow volume of the flow in the flow counter information; and identifies a flow in which a communication anomaly has occurred on the basis of results of a comparison process for comparing the input flow volume to the output flow volume with reference to the flow counter information.
