Medium for storing packet conversion program, packet conversion apparatus and packet conversion method
TLDR
In this paper, a packet conversion scheme is proposed to convert a packet including a broadcast/multicast MAC address from a virtual machine into a multicast packet by setting the subnet identifier obtained based on the first association information and the packet type identifier obtained in a field of the MAC address of the packet to be transmitted, and transmits the packet, which is obtained by being converted, to the different computer via the network.Abstract:
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.read more

Proxy methods for suppressing broadcast traffic in a network
TL;DR: In this article, the authors use proxies on host devices to suppress broadcast traffic in a network, where the proxy monitors the VM's traffic and intercepts broadcast packets when it knows how to deal with them, by connecting to the controller cluster, the proxy can obtain information that it can use to resolve broadcast requests.
Patent
Bit indexed explicit replication
TL;DR: In this paper, a neighbor node is selected based on comparing the multicast forwarding entry with forwarding information stored by the node, and forwarding the packet to the neighbor node based on the comparing.

Apparatus and method for communication processing
TL;DR: In this article, a method for determining whether or not a destination address of a received message is a predetermined address of the first virtual switch being operating is proposed. But it is not clear how to determine whether the destination address is the predetermined address.

Method and system for transparent lan services in a packet network
TL;DR: In this article, a CPE bridge is configured to determine a transparent local area network service (TLS) for a packet received from one of the internal network entities based on a media access control (MAC) address of a destination of the packet in a different separate customer network portion.
