Abstract
An optical communication device that communicates with another optical communication device using at least a time division multiplexing method, the optical communication device includes: a band request unit that requests a band for transmitting a management control signal used for management and control; and a transmitting unit that transmits the management control signal as a burst signal using a band assigned to be able to transmit data having a data length or more obtained based on a transmission rate of the management control signal, a transmission rate of a main signal, and a data length of the management control signal.
Claims7
An optical communication device that communicates with another optical communication device using at least a time division multiplexing method, the optical communication device comprising:
- a processor;
- and
- a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
- request a band for transmitting a AMCC signal used for management and control;
- and generate the AMCC signal;
- and
- a transmitter configured to transmit the AMCC signal as a burst signal using a band assigned to be able to transmit data having a data length or more obtained based on a transmission rate of the AMCC signal, a transmission rate of a main signal, and a data length of the AMCC signal.
An optical communication device that communicates with another optical communication device using at least a time division multiplexing method, the optical communication device comprising:
- a processor;
- and
- a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
- calculate a converted data length based on a following formula (1) using AMCC signal transmission rate indicating a transmission rate of an AMCC signal used for management and control, main signal transmission rate indicating a transmission rate of a main signal, and AMCC signal data length indicating a data length of the AMCC signal notified from the another optical communication device;
- compare the data length of the converted data length with a data length of the main signal accumulated in a buffer of the other optical communication device;
- and
- determine a band to be assigned to the other optical communication device according to a comparison result of the comparator, and transmits a gate frame including information of an assigned amount of the determined band to the other optical communication device
