Before describing each embodiment of the present disclosure, FTTR technology will be briefly described first.

FTTR technology refers to using optical fiber instead of network cables, laying optical fiber to every room, and realizing interconnection with home gateways by deploying optical networking terminals. Combined with dual-band wireless network technology (Wireless Fidelity, Wi-Fi), it ensures the security of the whole house. Network coverage networking technology. Based on the home Gigabit all-optical networking solution based on FTTR technology, the main optical modem (Optical Network Unit (ONU)) is deployed in the home wiring box or the center of the home. With the main optical modem as the core, point-to-point The multipoint (Point-to-Multipoint, P2MP)/point-to-point (Point-to-Point, P2P) method is based on optical splitters and single-core bidirectional optical fibers to build home optical fiber networks.

Figure 1 is a schematic system structure diagram for the application of the communication method according to the embodiment of the present disclosure; as shown in Figure 1, the system to which the communication method of this embodiment is applicable may include a first device, a second device and a third device; the first device uses P2MP The optical fiber network (first physical link) connects to the second device, and the second device connects to the third device through the P2MP optical network (second physical link). In the following embodiments of the present disclosure, The first device may be an optical line terminal (Optical Line Termination, OLT), and the second device may also be called a main optical network unit (Optical Network Unit, ONU) or a first type ONU, or it may also be an FTTR main unit. Device/FTTR main gateway/FTTR main ONU/Main FTTR Unit (MFU)/main gateway/main device, etc. The third device can also be called a slave ONU or a second type ONU, or it can also be an FTTR Slave device/FTTR slave gateway/FTTR slave ONU/edge FTTR unit (Edge FTTR Unit, EFU)/slave gateway/slave device, etc. The above device names are often used interchangeably in various embodiments of the present disclosure.

In this illustration, the system may include a first-level network and a second-level network; the first-level network includes a first device and one or more second devices, and the second-level network includes one or more second devices and One or more third devices to which each second device is connected.

For example, the first-level network may be a passive optical network (Passive Optical Network, PON) or a PON system. The second-level network may be, for example, FTTR or an indoor optical fiber network (Fiber In-premises Networking, FIN). In this embodiment, the first-level network and/or the second-level network are not limited.

Wherein, the first device is connected to the second device through a first link, and the second device is connected to the third device through a second link. Optionally, the first link may also be called a first physical link, a first-level physical link, or the like. For example, the first link may also be called a PON link. In Figure 1, the column mark between the first device and the second device may represent the first link. Correspondingly, the second link may also be called a second physical link, a second-level physical link, and so on. For example, the second link may also be called an FTTR link or a FIN link, or the like. In Figure 1, the column mark between each second device and the corresponding third device may represent the second link.

The uplink communication mechanism of FTTR is based on time division multiplexing. Traditional point-to-multipoint optical communication systems are mainly used in access networks. For example, the central office side OLT connects multiple terminal side ONUs through point-to-multipoint line interfaces. The ONUs provide user-side interfaces to access user services. The network topology is level one. Tree structure. If the ONU supports point-to-multipoint line interfaces on the user side, a multi-level tree topology of point-to-multipoint system cascade can be formed to meet the needs of access and premises network/LAN networking respectively. However, traditional point-to-multipoint systems are Applied to access networks and using a single-hop topology, traditional uplink scheduling solutions can only be implemented on single-level tree networks. If the multi-level cascade can only be scheduled in segments (hop-by-hop), that is, the upstream traffic from the slave ONU needs to go through the two-level Dynamic Bandwidth Allocation (DBA) scheduling of the main ONU and OLT. Each additional level of DBA scheduling increases the upstream traffic. The communication delay will become larger, so the uplink communication delay will be greatly increased, making it impossible to achieve multi-level tree topology low-latency communication for point-to-multipoint system cascading.

17. The method of claim 15, further comprising:

    The third device receives the second information sent by the second device, and the second information is used to notify the third device to send a second cache status report;

    The third device sends the second cache status report to the second device.
18. A communication device, the device is used in a first device, and the first device is connected to one or more second devices through a first link; the device includes: a first sending unit for transmitting data through a first bandwidth The allocation process allocates the first uplink sending opportunity of the second device to the first traffic bearing entity in the second device; the first bandwidth allocation process is implemented based on at least the first cache status report of the second device, so The first cache status report includes first cache occupancy status information associated with the first traffic carrying entity, and/or, associated with the second traffic carrying entity of the third device associated with the first traffic carrying entity second cache occupancy status information, the second traffic carrying entity is used to carry uplink traffic entering the first link;

    Each second device is connected to one or more third devices through a second link.
19. A communication device, the device is used in a second device; the second device is connected to a first device through a first link, and the second device is connected to one or more third devices through a second link; the The apparatus includes a second receiving unit configured to receive a first uplink sending opportunity allocated by the first device to the first traffic bearing entity in the second device through a first bandwidth allocation process, the first bandwidth allocation being based at least on the The second device implements a first cache status report, where the first cache status report includes first cache occupancy status information associated with the first traffic bearing entity, and/or, the first cache occupancy status information associated with the first traffic bearing entity Second cache occupancy status information associated with a second traffic carrying entity of the third device, the second traffic carrying entity being used to carry uplink traffic entering the first link.
20. A communication device, the device is used in a third device, and one or more third devices are connected to a second device through a second link; the device includes a second processing unit for identifying uplink traffic, based on The identification result maps the upstream traffic to the corresponding second traffic bearing entity.
21. A computer-readable storage medium with a computer program stored thereon, wherein the steps of the method of any one of claims 1 to 4 are implemented when the program is executed by a processor; or,

    When the program is executed by the processor, the steps of the method described in any one of claims 5 to 14 are implemented; or,

    This program, when executed by a processor, implements the steps of the method described in any one of claims 15 to 17.
22. A communication device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the method of any one of claims 1 to 4 is implemented. steps; or,

    When the processor executes the program, the steps of the method described in any one of claims 5 to 14 are implemented; or,

    When the processor executes the program, the steps of the method described in any one of claims 15 to 17 are implemented.
