Abstract
A radio communication apparatus including: a radio communication interface; and a processor; the processor being configured to detect a first radio communication apparatus and a second radio communication apparatus based on a piece of address information received by the radio communication interface; and to select one of a first layer and a second layer as a forwarding layer, in which a packet is forwarded to a next forwarding address according to the radio communication apparatus of the next forwarding address corresponding to a destination address of the packet.
Claims7
A radio communication apparatus comprising:
- a radio communication interface configured to transmit or receive radio signals;
- and
- a processor configured
- to control the radio communication interface to forward a packet to a next forwarding destination in a first layer;
- to control the radio communication interface to forward the packet to the next forwarding destination in a second layer which is higher than the first layer;
- to control the radio communication interface to receive a piece of address information of another radio communication apparatus in the first layer from a first radio communication apparatus as the other radio communication apparatus which forwards the packet in the first layer;
- to control the radio communication interface to receive the piece of address information of the other radio communication apparatus in the second layer from the first radio communication apparatus and receives the piece of the address information of the radio communication apparatus of a second type in the second layer from a second radio communication apparatus which forwards the packet in the second layer;
- to detect the first radio communication apparatus and the second radio communication apparatus based on the piece of address information received by the radio communication interface;
- and
- to select one of the first layer and the second layer as a forwarding layer, in which the packet is forwarded to a next forwarding address according to the radio communication apparatus of the next forwarding address corresponding to a destination address of the packet.
A forwarding method of a packet which is performed by a radio communication apparatus, comprising:
- receiving a piece of address information of the first radio communication apparatus in the first layer from the first radio communication apparatus as another radio communication apparatus which selects one of the first layer and the second layer which is higher than the first layer as a layer in which the packet is forwarded;
- receiving the piece of address information, from the first radio communication apparatus, of the other radio communication apparatus in the second layer, and the piece of address information, from the second radio communication apparatus which forwards a packet in the second layer, of the second radio communication apparatus in the second layer;
- detecting the first radio communication apparatus and the second radio communication apparatus based on the received piece of address information;
- selecting one of the first layer and the second layer as the layer in which the packet is forwarded to the next forwarding address according to the radio communication apparatus of the next forwarding address which is specified for the destination address of the packet;
- and
- forwarding the packet in the selected layer to the next forwarding address.
