Medium for storing packet conversion program, packet conversion apparatus and packet conversion method

摘要

Upon obtaining a packet including a broadcast/multicast MAC address from a virtual machine, a packet conversion apparatus obtains, based on first association information, a subnet identifier corresponding to the MAC address of the obtained packet, also obtains, based on second association information, a packet type identifier corresponding to the MAC address of the obtained packet, converts the packet to be transmitted to a different computer via a network into a multicast packet by setting the subnet identifier obtained based on the first association information and the packet type identifier obtained based on the second association information in a field of the MAC address of the packet to be transmitted, and transmits the packet to be transmitted, which is obtained by being converted, to the different computer via the network.

主权项

1. A non-transitory computer-readable medium storing a packet conversion program for causing a computer, which has a storing unit configured to store first association information between a MAC address of a virtual machine connected to a virtual switch and a subnet identifier for identifying a subnet to which the virtual machine belongs, and second association information between a MAC address representing a broadcast address or a multicast address and a packet type identifier to perform procedures, the procedures comprising:
obtaining a packet including the MAC address representing the broadcast address or the multicast address from the virtual machine; obtaining, from the first association information, the subnet identifier corresponding to the MAC address of the obtained packet; obtaining, from the second association information, the packet type identifier corresponding to the MAC address of the obtained packet; converting the obtained packet into a multicast packet by setting the subnet identifier obtained from the first association information and the packet type identifier obtained from the second association information in a field of the MAC address of the obtained packet; and transmitting the converted packet to a different computer via a network.
