Abstract
An optical communication system connects one to a plurality subscriber-side apparatuses having one to a plurality of subscriber terminals and a station-side apparatus that covers the subscriber-side apparatuses with an optical transmission medium, sets one to a plurality of logical links between the station-side apparatus and each subscriber-side apparatus, and performs a data transfer with an MAC frame using a set logical link. The station-side apparatus and the subscriber-side apparatus transmit control information of a plurality of set logical links by storing the control information in a single MAC frame.

An optical communication system comprising:
- one to a plurality of subscriber-side apparatuses having one to a plurality of subscriber terminals;
- a station-side apparatus that covers the subscriber-side apparatuses;
- and
- an optical transmission medium that connects the subscriber-side apparatuses and the station-side apparatus, wherein
- one to a plurality of logical links is set between the station-side apparatus and each subscriber-side apparatus,
- a data transfer is performed between the station-side apparatus and the subscriber-side apparatus with a media access control frame through a set logical link, and
- the station-side apparatus and the subscriber-side apparatus transmit control information of a plurality of set logical links by storing the control information in a single media access control frame.
An optical communication system comprising:
- one to a plurality of subscriber-side apparatuses having one to a plurality of subscriber terminals;
- a station-side apparatus that covers the subscriber-side apparatuses;
- and
- an optical transmission medium that connects the subscriber-side apparatuses and the station-side apparatus, wherein
- one to a plurality of logical links is set between the station-side apparatus and each subscriber-side apparatus,
- a data transfer is performed between the station-side apparatus and the subscriber-side apparatus with a media access control frame through a set logical link, and
- the station-side apparatus and the subscriber-side apparatus equate a media access control layer and a multi-point control protocol layer with each other in a protocol stack, and transmit control information of a plurality of set logical links to a counterparty by attaching the control information following a delimiter of a physical layer.
A station-side apparatus configured to be connected to one to a plurality of subscriber-side apparatuses having one to a plurality of subscriber terminals via an optical transmission medium in an optical communication system, sets one to a plurality of logical links with each subscriber-side apparatus, and performs a data transfer with the subscriber-side apparatus with a media access control frame using a set logical link, the station-side apparatus comprising:
- a GATE generating unit that transmits control information of a plurality of set logical links to the subscriber-side apparatus by storing the control information in a single media access control frame.
A subscriber-side apparatus that has one to a plurality of subscriber terminals, is configured to be connected to a station-side apparatus via an optical transmission medium in an optical communication system, sets one to a plurality of logical links with the station-side apparatus, and performs a data transfer with the station-side apparatus with a media access control frame using a set logical link, the subscriber-side apparatus comprising:
- a REPORT generating unit transmits control information of a plurality of set logical links to the station-side apparatus by storing the control information in a single media access control frame.
An optical communication system comprising:
- one to a plurality of subscriber-side apparatuses having one to a plurality of subscriber terminals;
- a station-side apparatus that covers the subscriber-side apparatuses;
- and
- an optical transmission medium that connects the subscriber-side apparatuses and the station-side apparatus, wherein
- one to a plurality of logical links is set between the station-side apparatus and each subscriber-side apparatus,
- a data transfer is performed between the station-side apparatus and the subscriber-side apparatus with a media access control frame through a set logical link, and
- the station-side apparatus and the subscriber-side apparatus equate a media access control layer and a multi-point control protocol layer with each other in a protocol stack, and transmit control information of a plurality of set logical links to a counterparty by attaching the control information following a preamble of the media access control layer.
An optical communication system comprising:
- one to a plurality of subscriber-side apparatuses having one to a plurality of subscriber terminals;
- a station-side apparatus that covers the subscriber-side apparatuses;
- and
- an optical transmission medium that connects the subscriber-side apparatuses and the station-side apparatus, wherein
- one to a plurality of logical links is set between the station-side apparatus and each subscriber-side apparatus, a data transfer is performed between the station-side
- apparatus and the subscriber-side apparatus with a media access control frame through a set logical link, and
- the station-side apparatus and the subscriber-side apparatus equate a media access control layer, a multi-point control protocol layer, and an operations-administration-maintenance layer with each other in a protocol stack, and transmit control information of a plurality of set logical links to a counterparty by attaching the control information following a preamble of the media access control layer.
