Abstract
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.
