Abstract
Transmission equipment includes: a first interface unit configured to receive a frame; and a second interface unit configured to transmit the received frame received by the first interface unit. The second interface unit includes a transmission circuit configured to transmit path information that represents a state of a logical path pair including a work path and a protection path provided for the received frame to the first interface unit. The first interface unit includes a destination determination circuit configured to determine a destination of the received frame based on the state of the logical path pair represented by the path information received from the second interface unit.
Claims15
Transmission equipment comprising:
- a first interface unit configured to receive a frame;
- and
- a second interface unit configured to transmit the received frame received by the first interface unit, wherein
- the second interface unit includes a transmission circuit configured to transmit path information that represents a state of a logical path pair including a work path and a protection path provided for the received frame to the first interface unit, and
- the first interface unit includes a destination determination circuit configured to determine a destination of the received frame based on the state of the logical path pair represented by the path information received from the second interface unit.
A transmission method used in transmission equipment including a first interface unit that receives a frame and a second interface unit that transmits the received frame received by the first interface unit, the transmission method comprising:
- collecting, in the second interface unit, path information that represents a state of a logical path pair including a work path and a protection path provided for the received frame;
- transmitting the path information from the second interface unit to the first interface unit;
- and
- determining, in the first interface unit, a destination of the received frame based on the state of the logical path pair represented by the path information received from the second interface.
Transmission equipment comprising:
- a first interface unit configured to process a received frame of a work path;
- a second interface unit configured to process a received frame of a protection path corresponding to the work path;
- and
- a third interface unit configured to select one of the received frame of the first interface unit and the received frame of the second interface, wherein
- the first interface unit includes a first transmission circuit configured to transmit first path information representing a state of the work path to the third interface unit,
- the second interface unit includes a second transmission circuit configured to transmit second path information representing a state of the protection path to the third interface unit, and
- the third interface unit includes a selector configured to select one of the received frame of the first interface unit and the received frame of the second interface unit based on the first and second path information.
