Abstract:
1. A network communication apparatus which can transmit multicast packets comprising: a communication interface unit that has a plurality of IP addresses allocated to the communication interface unit and transmits the multicast packets; and a multicast control unit that controls the communication interface unit and groups the plurality of IP addresses into a plurality of groups including a first group and a second group based on predetermined criteria, wherein the multicast control unit sequentially transmits the multicast packets using one IP address belonging to the first group as a transmission source such that after transmission of one multicast packet is complete, another multicast packet is transmitted using another IP address belonging to the first group as a transmission source address, the transmission source representing where the multicast packet is transmitted from, wherein the multicast control unit sequentially transmits the multicast packets using one IP address belonging to the second group as a transmission source address such that after transmission of one multicast packet is complete, another multicast packet is transmitted using another IP address belonging to the second group as a transmission source address, and wherein the transmission source address represents where the multicast packet is transmitted from, and wherein each of the first group and the second group include a plurality IP addresses.
