TRANSFER DEVICE, CONTROL DEVICE, AND TRANSFER METHOD

摘要

A transfer device in a network including a plurality of control devices includes a network connection device, memory, and a processor. The network connection device communicates a target packet as a target of a transferring process. The memory stores a transfer rule received by the network connection device from a determination device as a control device for determining a transfer rule indicating a method of a process performed by the transfer device. The processor judges whether or not disable information indicating that the transfer rule is not to be acquired from the determination device when a transfer rule applicable to the target packet is not stored in the memory is included in the target packet. When the disable information is included, the processor outputs the target packet to the network connection device without requesting the transfer rule. The network connection device transmits the target packet to another transfer device.

主权项

1. A transfer device in a network provided with a plurality of control devices, the transfer device comprising:
a network connection device configured to communicate a target packet to be transferred; a memory configured to store a transfer rule which has been received by the network connection device from a determination device as a control device which determines a transfer rule indicating a method of a process performed by the transfer device; and a processor, wherein: the processor
judges whether or not disable information indicating that the transfer rule is not acquired from the determination device is included in the target packet when a transfer rule applicable to the target packet is not stored in the memory; andoutputs to the network connection device the target packet without requesting the transfer rule applicable to the target packet to the determination device when the disable information is not included, and the network connection device transmits the target packet to another transfer device.
