Abstract
A communication device, a multicast control method, and a scheduling control method are disclosed. The communication device includes: a decoding buffer that stores a first multicast packet received from a first node and a second multicast packet received from a second node; an encoder that performs network coding of the first and second multicast packets; and a transmitter that transmits the network-coded packets output from the encoder to the first node and the second node.
Claims14
A communication device comprising:
- a decoding buffer that stores a first multicast packet received from a first node and a second multicast packet received from a second node;
- an encoder that performs network coding of the first and second multicast packets;
- and
- a transmitter that transmits the network-coded packets output from the encoder to the first node and the second node.
A multicast control method comprising:
- transmitting a first multicast packet to at least one neighboring node and a relay node from one of a plurality of nodes constituting a network;
- performing network coding of the first multicast packet and a second multicast packet received from a destination node and transmitting the first and second multicast packets to the node and the at least one neighboring node from the relay node;
- and
- decoding the network-coded packets by using the first multicast packet to enable the node and the at least one neighboring node to acquire the second multicast packet.
A scheduling control method comprising:
- scheduling a transmission priority of a first multicast packet by one of a plurality of nodes constituting a network;
- scheduling a transmission priority of a second multicast packet;
- and
- scheduling a transmission priority of the first and second multicast packets, which are network-coded, according to the scheduling of the first multicast packet and the scheduling of the second multicast packet.
