Abstract
A communication device includes: a first transmission-reception unit connected with a first optical line terminal; a second transmission-reception unit connected with a second optical line terminal; and a control unit, the first transmission-reception unit acquires a control signal having a destination at the second or third optical line terminal from the first optical line terminal, the control unit forwards the control signal toward the second transmission-reception unit connected with the second or third optical line terminal, and the second transmission-reception unit forwards the control signal to the second or third optical line terminal.
Claims12
A communication device comprising:
- a first transmission-reception unit connected with a first optical line terminal;
- a second transmission-reception unit being connected with a second optical line terminal replaceable with a third optical line terminal;
- and
- a control unit, wherein the communication device executes any of processing in which
- the first transmission-reception unit acquires a control signal having a destination at the second or third optical line terminal from the first optical line terminal,
- the control unit forwards the control signal toward the second transmission-reception unit connected with the second or third optical line terminal, where the second transmission-reception unit to which a virtual local area network (VLAN) is same as a VLAN allocated to the first transmission-reception unit having acquired the control signal is allocated, and
- the second transmission-reception unit forwards the control signal toward the second or third optical line terminal, and
- processing in which
- the second transmission-reception unit acquires a control signal having a destination at the first optical line terminal from the second or third optical line terminal,
- the control unit forwards the control signal toward the first transmission-reception unit connected with the first optical line terminal, where the first transmission-reception unit to which a VLAN is same as a VLAN allocated to the second transmission-reception unit having acquired the control signal is allocated, and
- the first transmission-reception unit forwards the control signal toward the first optical line terminal.
A communication method executed by a communication device including a first transmission-reception unit, a second transmission-reception unit, and a control unit, the first transmission-reception unit being connected with a first optical line terminal, the second transmission-reception unit being connected with a second optical line terminal replaceable with a third optical line terminal, the communication method comprising:
- a step of acquiring, by the first transmission-reception unit, a control signal having a destination at the second or third optical line terminal from the first optical line terminal;
- a step of forwarding, by the control unit, the control signal toward the second transmission-reception unit connected with the second or third optical line terminal, where the second transmission-reception unit to which a virtual local area network (VLAN) is same as a VLAN allocated to the first transmission-reception unit having acquired the control signal is allocated;
- and
- a step of forwarding, by the second transmission-reception unit, the control signal to the second or third optical line terminal,
- or the communication method comprising:
- a step of acquiring, by the second transmission-reception unit, a control signal having a destination at the first optical line terminal from the second or third optical line terminal;
- a step of forwarding, by the control unit, the control signal toward the first transmission-reception unit connected with the first optical line terminal, where the first transmission-reception unit to which a VLAN is same as a VLAN allocated to the second transmission-reception unit having acquired the control signal is allocated;
- and
- a step of forwarding, by the first transmission-reception unit, the control signal to the first optical line terminal.
