摘要： To improve fault tolerance of a ring network, provided is a data transfer device system belonging to a ring network system. The data transfer device system includes a plurality of data transfer devices; the plurality of data transfer devices including a first data transfer device and a second data transfer device connected with the first data transfer device; the first data transfer device having a first ring port; and the second data transfer device having a second ring port. The first data transfer device controls whether to permit the first ring port and the second ring port to transfer data based on a state of the network system, an attribute of the first data transfer device in the data transfer device system, and an attribute of the data transfer device system in the network system.

摘要： A transfer apparatus comprises: a first storage unit configured to store a whitelist for storing reliable information indicating that communication between a source address and a destination address is authorized; a second storage unit configured to store an addition list including a specific address not included in the reliable information and a valid period of the specific address; a receiving unit configured to receive data; a check unit configured to check whether either a destination address or a source address included in data within the valid period is the specific address; and a generation unit configured to generate specific reliable information indicating that communication between the destination address and the source address included in the data is authorized and register the generated specific reliable information to the whitelist in a case where the check unit confirms within the valid period that either address is the specific address.
