摘要： According to one embodiment, a receiving unit receives a frame from a first external communication device connected to a first communication port. First and second databases store destination determination information used to determine a second communication port to which a second external communication device is connected. A determination unit determines the second communication port by accessing destination determination information in the first database when the received frame is a first frame, and determines the second communication port by accessing destination determination information in the second database when the received frame is a second frame. The first database is accessible to the destination determination information at a higher speed than the second database.

摘要： According to an embodiment, a switch device includes a memory and one or more hardware processors coupled to the memory. The one or more hardware processors are configured to function as a selection unit and a determination unit. The selection unit, based on task schedule information synchronized with transmission schedule information where transmission timing of first data is determined for each priority of the first data, selects a first task of executing transfer processing of the first data and calculates an end time of transfer processing executed by the selected first task. The determination unit, from the end time and a current time, determines whether transfer processing of the first data is executable. The first task selected by the selection unit, when the transfer processing is executable, executes the transfer processing of the first data based on the transmission schedule information.

摘要： There is provided a communication device which communicates with a target communication device, including: a communication controller, a general-purpose processing unit, a data transfer processing unit and a starting unit. The general-purpose processing unit communicates with the target communication device via the communication controller. The data transfer processing unit receives data from the target communication device via the communication controller. The starting unit starts up the data transfer processing unit. The general-purpose processing unit receives a data transfer start request from the target communication device. The starting unit starts up the data transfer processing unit when the general-purpose processing unit receives the data transfer start request. The general-purpose processing unit or the data transfer processing unit notifies a data transfer start response to the target communication device after the data transfer processing unit is started up.

摘要： According to an embodiment, a communication apparatus includes a plurality of virtual machines, a storage unit, a transfer unit, and a descriptor output unit. The storage unit includes a multicast storage area specified for each multicast group and storing a multicast frame addressed to virtual machines belonging to a multicast group. The transfer unit writes the multicast frame into a multicast transfer virtual storage area mapped to the multicast storage area. The descriptor output unit outputs a descriptor of the multicast frame to the virtual machines belonging to the multicast group. The virtual machine includes a descriptor receiving unit and a reading unit. The descriptor receiving unit receives the descriptor. When the descriptor is received by the descriptor receiving unit, the reading unit reads the multicast frame from the multicast storage area specified based on the descriptor.
