[0028] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] In order to facilitate understanding of the solutions of the embodiments of the present application and to make the description of the following embodiments clear and concise, a brief introduction to the relevant technologies is first given:

[0030] Passive Optical Network (PON): Passive optical network refers to an optical distribution network (ODN) between the optical line terminal (OLT) and the optical network unit (ONU), without any active communication equipment. One end of the OLT is connected to the upper network to complete the upstream access of the PON. The upper network can be an Internet protocol (IP) backbone network or a public switched telephone network (PSTN). The other end of the OLT is connected to the user-end device through the ODN to complete the downstream transmission of the PON and realize the control, management and ranging functions of the user-end device. The user-end device can be an ONU. One end of the user-end device is connected to the OLT through the ODN, and the other end of the user-end device is connected to other terminal devices, such as computers, landlines, etc. ONU works with OLT to realize Ethernet layer 2 and layer 3 functions and provide voice, data and multimedia services to users. For example, the ONU can select and receive data sent by the OLT; respond to management commands issued by the OLT and make corresponding adjustments; cache the user's Ethernet data and send it to the uplink in the sending window allocated by the OLT; and perform other user management functions.

[0031] Fiber To The Home (FTTH): is the installation and use of optical fiber from a central point directly to individual buildings such as homes, apartment buildings and businesses to provide high-speed Internet access.

[0032] Fiber to the Room (FTTR): refers to the use of fiber optic access to all home broadband, so that each room can guarantee the same Internet speed as the home broadband and will not be affected. FTTR is similar to FTTH (Fiber to the Home), using a point-to-multipoint network topology, with the main device (Main FTTR Unit, MFU) connecting multiple slave devices (Sub FTTR Unit, SFU) through the indoor optical distribution network (Indoor Fibre Distribution Network, IFDN).

[0033] See also Figure 1 , Figure 1 1 is a schematic diagram of an implementation environment of the bandwidth allocation method provided in an embodiment of the present application, wherein the implementation environment includes an OLT, at least one master device and at least one slave device. Figure 1In the example shown, one OLT is connected to multiple master devices, and each master device is respectively connected to multiple slave devices, wherein the OLT can be connected to the multiple master devices through the ODN, and the master device can be connected to the multiple slave devices through the IFDN.

[0034] Exemplarily, the master device can be connected to one or more home user devices, receive service messages sent by the home user devices, and forward the service messages. Similarly, the slave device can also be connected to one or more home user devices, receive service messages sent by the home user devices, and forward the service messages.

[0035] In the embodiment of the present application, the service messages sent by the home user equipment can be divided into east-west service messages and north-south service messages according to service attributes.

[0036] Among them, the east-west service can represent a home interconnection service, the destination address of the east-west service is the home user device address, and the east-west service message is forwarded to the home user device corresponding to the destination address through the FTTR networking device. For example, the master device receives the east-west service message from the home user device, and then forwards the service message to the corresponding slave device according to the destination address, and then the slave device forwards it to the home user device corresponding to the destination address; or, slave device 1 receives the east-west service message from the home user device, and then forwards the service message to the master device, the master device forwards the service message to slave device 2 according to the destination address, and then slave device 2 forwards it to the home user device corresponding to the destination address.

[0037] The north-south service may represent an access service, and the access service may be an Ethernet service, a Synchronous Digital Hierarchy (SDH) service, etc. For example, the Ethernet / SDH service message is first forwarded to the FTTH network device through the FTTR network device, and then enters the upper layer device through the FTTH device to achieve service access. Exemplarily, the master device receives the north-south service message from the home user device, and then forwards the service message to the OLT, and then achieves network access through the OLT; or, the slave device receives the north-south service message from the home user device, and then forwards the service message to the master device, and the master device then forwards the service message to the OLT, and then enters the upper layer device through the OLT to achieve the service access function.

[0038] Exemplarily, the home user device may be a handheld device, a wearable device or a computing device with a wireless communication function. Specifically, the home user device may be a mobile phone, a tablet computer, a smart electrical device or a computer with a wireless transceiver function. The home user device may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wired / wireless terminal in industrial control, a wired / wireless terminal in telemedicine, a wired / wireless terminal in a smart home, a wired / wireless terminal in a smart grid, a wired / wireless terminal in a smart city, and the like.

[0039] It should be noted that, in the embodiment of the present application, the transmission direction from the home user device to the OLT is referred to as the uplink direction, and the transmission direction from the OLT to the home user device is referred to as the downlink direction.

[0040] In the current networking applications of related technologies, FTTR and FTTH are two independent networks that cannot coordinate in resource allocation. Specifically, the east-west services transmitted only in the FTTR segment and the north-south services transmitted in the FTTH and FTTR segments cannot coordinate in bandwidth allocation, and the bandwidth of the north-south services in the FTTH and FTTR segments cannot be coordinated, making it difficult to achieve low-latency transmission or deterministic latency transmission of the services.

[0041] See also Figure 2 , Figure 2 Schematic diagram of an integrated FTTH and FTTR network architecture provided by an embodiment of the present application. Figure 2 As shown in the figure, when FTTH and FTTR are integrated into a network, Figure 1 The OLT in the FTTH architecture is used as the OLT in the FTTH architecture and can be called FTTH OLT; Figure 1 The main device in the FTTH architecture also serves as the ONU in the FTTH architecture and the OLT in the FTTR architecture, so the main device can be considered to consist of two modules: the FTTH ONU and the FTTR OLT; Figure 1 The slave device in the FTTR architecture is used as an ONU and can be called an FTTR ONU.

[0042] Based on the problems existing in the related art, the embodiments of the present application provide a bandwidth allocation method, a communication device and a computer-readable storage medium, which can realize the coordination of bandwidth resources of FTTR and FTTH, thereby improving the service determinism of the network. In the embodiment of the present application, the master device receives a bandwidth request for a first service sent by a slave device, then determines the service attributes of the first service, and then performs a bandwidth allocation operation according to the service attributes of the first service. The embodiment of the present application coordinates the allocation of bandwidth resources between FTTR and FTTH by performing corresponding bandwidth allocation operations according to the service attributes through the master device, and provides support for improving the service determinism of the network.

[0043] See also Figure 3 , Figure 3 FIG. 1 is another schematic diagram of an integrated FTTH and FTTR network architecture provided in an embodiment of the present application. Figure 3 In the example, the master device includes an FTTH ONU and a forwarding channel, wherein the forwarding channel is a PON layer forwarding channel located between the OLT and the slave device, and the forwarding channel is used to forward the upstream frame of the slave device to the OLT, or to forward the downstream frame from the OLT to the slave device. Exemplarily, the upstream frame can be an upstream service message, a bandwidth request, or other upstream message, and the downstream frame can be a downstream service message, a bandwidth application response, or other downstream message.

[0044] It should be noted that the equal delay forwarding described in the embodiment of the present application means that the time required for the uplink frame / downlink frame to enter the main device and leave the main device remains the same. If the standards of the FTTH and FTTR segments are the same, there is no need to convert the standards, and equal delay forwarding is sufficient. If the standards of the FTTH segment and the FTTR segment are different, the data frame needs to be converted. During the standard conversion, if the functions of the two segments are inconsistent, it is necessary to delete some content in the segment with more functions, or add some content to the segment with fewer functions.

[0045] The forwarding channel provided in the embodiment of the present application can realize deterministic forwarding of uplink frames / downlink frames, that is, the forwarding delay of the master device for the uplink frames / downlink frames is deterministic, for example, the master device is limited to complete the forwarding of the uplink frames / downlink frames within the first delay.

[0046] See also Figure 4 , Figure 4 is a flow chart of a bandwidth allocation method provided in an embodiment of the present application. The execution subject of the bandwidth allocation method may be Figure 1 or Figure 3 The main device in the implementation environment shown. Figure 4 As shown, the bandwidth allocation method may include but is not limited to the following steps S110-S120, and each step is introduced in turn below:

[0047] Step S110: Receive a bandwidth request for a first service sent from a device.

[0048] Exemplarily, the slave device receives a connection configuration request for a new service initiated by a home user device, where the new service is referred to as a first service. The slave device responds to the connection configuration request for the first service by sending a bandwidth request to the master device to apply for bandwidth for the first service.

[0049] Step S120: Execute bandwidth allocation related operations according to the service attributes of the first service.

[0050] Illustratively, the service attribute of the first service may be an east-west attribute or a north-south attribute.

[0051] Exemplarily, the service attribute of the service can be distinguished according to whether the destination address of the service is a home user device address. For example, if the destination address of the current service is a home user device address, the current service can be considered as an east-west service, otherwise the current service is considered as a north-south service.

[0052] In the embodiment of the present application, the master device performs corresponding bandwidth allocation operations according to whether the first service is an east-west service or a north-south service, so as to achieve bandwidth resource coordination between FTTR and FTTH, thereby improving the service determinism of the network.

[0053] Exemplarily, the OLT may configure multiple uplink channels with channel attributes for the slave device to establish multiple uplink channels with channel attributes between the slave device and the master device, wherein the channel attribute may be an east-west attribute or a north-south attribute.

[0054] For example, the uplink channel may be a transmission container (Transmission CONT, T-CONT). Figure 5a , Figure 5a Schematic diagram of an uplink channel construction provided in an embodiment of the present application. Figure 5a As shown, multiple T-CONTs with channel attributes are established between the slave device and the master device, namely T-CONT1 and T-CONT2, wherein the channel attribute of T-CONT1 is an east-west attribute, and the channel attribute of T-CONT2 is a north-south attribute.

[0055] For example, the uplink channel may be a GPON encapsulation mode port (GEM Port). Figure 5b , Figure 5b FIG. 1 is another schematic diagram of constructing an uplink channel provided in an embodiment of the present application. Figure 5bAs shown, T-CONT1 and T-CONT2 are established between the slave device and the master device, T-CONT1 includes GEM Port1 and GEM Port2, T-CONT2 includes GEM Port3 and GEMPort4, wherein the channel attribute of T-CONT1 is an east-west attribute, and the channel attributes of GEM Port1 and GEM Port2 included therein are also east-west attributes, and the channel attribute of T-CONT2 is a north-south attribute, and the channel attributes of GEM Port3 and GEM Port4 included therein are also north-south attributes. It can be understood that GEM Port is the smallest transmission unit of a service, and a T-CONT can include multiple GEM Ports, and the attributes of the GEM Port match the attributes of the T-CONT in which it is located.

[0056] In an embodiment of the present application, the slave device can map the bandwidth request corresponding to the service to the uplink channel with matching attributes according to the service attributes of the service, so as to obtain the uplink bandwidth through the uplink channel request, and after obtaining the bandwidth allocation, map the uplink service frame corresponding to the service to the uplink channel with matching attributes, and transmit the uplink service frame to the master device in the uplink channel using the corresponding uplink bandwidth. For example, the slave device maps the east-west service bandwidth request to the uplink channel with east-west attributes, obtains the uplink bandwidth through the uplink channel request with east-west attributes, and after obtaining the east-west bandwidth allocation, maps the uplink service frame of the east-west service to the uplink channel with east-west attributes, and transmits the uplink service frame to the master device through the uplink channel with east-west attributes. Alternatively, the slave device maps the north-south service bandwidth request to the uplink channel of the north-south attribute, obtains the uplink bandwidth through the uplink channel request of the north-south attribute, and after obtaining the north-south bandwidth allocation, the slave device maps the uplink service frame of the north-south service to the uplink channel of the north-south attribute, and transmits the uplink service frame to the master device through the uplink channel of the north-south attribute. In the above process, the master device can also determine the service attributes of the uplink service frame according to the channel attributes of the uplink channel for transmitting the uplink service frame.

[0057] It should be noted that the OLT configures multiple uplink channels with channel attributes for the slave device, and can also allocate a specific bandwidth to each uplink channel, and each uplink channel transmits an uplink frame through the allocated bandwidth. Exemplarily, the uplink frame can be a service data message, a service bandwidth request, or other service message.

[0058] Exemplarily, the slave device sends a bandwidth request for the first service to the master device through the first uplink channel. Based on this, the process of determining the service attribute of the first service may specifically include the following steps S121 and S122:

[0059] Step S121: determining a channel attribute of a first uplink channel, wherein the channel attribute includes an east-west attribute or a north-south attribute;

[0060] Step S122: Determine that the service attribute of the first service is an east-west attribute based on that the channel attribute of the first uplink channel is an east-west attribute; or, determine that the service attribute of the first service is a north-south attribute based on that the channel attribute of the first uplink channel is a north-south attribute.

[0061] Exemplarily, the master device receives a bandwidth request for a first service from a first uplink channel with an east-west attribute, determines that the service attribute of the first service is an east-west attribute based on the channel attribute of the first uplink channel being an east-west attribute, and then performs operations related to allocating east-west bandwidth for the first service.

[0062] Exemplarily, the main device receives a bandwidth request for the first service from the first uplink channel with a north-south attribute, determines that the service attribute of the first service is a north-south attribute based on the channel attribute of the first uplink channel being a north-south attribute, and then performs operations related to allocating north-south bandwidth for the first service.

[0063] In one implementation, when it is confirmed that the first service is an east-west service, in step S120, bandwidth allocation related operations are performed according to the service attributes of the first service, which may specifically include: allocating east-west bandwidth to the first service according to the service attributes of the first service being east-west attributes.

[0064] In another embodiment, when it is confirmed that the first service is an east-west service, in step S120, bandwidth allocation related operations are performed according to the service attributes of the first service, which may specifically include: according to the service attribute of the first service being an east-west attribute, the bandwidth request for the first service is forwarded to the optical line terminal OLT, so that the OLT allocates east-west bandwidth to the first service according to the bandwidth request.

[0065] In the case where the first service is an east-west service, the embodiment of the present application provides two implementation methods for allocating east-west bandwidth to the first service, the first being to allocate east-west bandwidth to the first service through the master device, and the second being to allocate east-west bandwidth to the first service through the OLT. In the second implementation method, the master device forwards the bandwidth request with equal delay to the OLT through a locally constructed forwarding channel, so that the OLT responds to the bandwidth request and allocates east-west bandwidth to the first service.

[0066] Exemplarily, allocating the east-west bandwidth to the first service specifically includes: determining the remaining bandwidth according to the total bandwidth of the main device and the used north-south bandwidth; and allocating the east-west bandwidth to the first service from the remaining bandwidth.

[0067] It is understandable that the OLT can distinguish between north-south bandwidth demands and allocate north-south bandwidth according to the total bandwidth under the OLT. It can also distinguish between east-west bandwidth demands and allocate east-west bandwidth to each master device agent. Combine the north-south bandwidth allocation, subtract the north-south bandwidth allocation related to the master device, and allocate east-west bandwidth for the remaining bandwidth under the master device.

[0068] When it is confirmed that the first service is a north-south service, in step S120, bandwidth allocation related operations are performed according to the service attributes of the first service, which may specifically include: according to the service attribute of the first service being a north-south attribute, a bandwidth request for the first service is forwarded to the OLT with equal delay, so that the OLT allocates north-south bandwidth for the first service according to the bandwidth request.

[0069] For bandwidth requests for north-south services, the master device forwards the bandwidth requests with equal delay to the OLT, and the OLT allocates north-south bandwidth for the north-south services.

[0070] Specifically, the OLT may allocate the north-south bandwidth of the FTTH segment to the first service from its own total bandwidth and allocate the north-south bandwidth of the FTTR segment to the first service from the total bandwidth of the main device according to its own total bandwidth and the total bandwidth of the main device.

[0071] It should be noted that when the OLT configures an uplink channel for the slave device, it also allocates a fixed bandwidth for the uplink channel. When the slave device transmits the bandwidth request to the master device through the first uplink channel, the master device forwards the bandwidth request to the OLT through the forwarding channel with equal delay. The OLT can determine which uplink channel the bandwidth request comes from based on the bandwidth used for bandwidth request transmission, and then determine whether the service currently requesting bandwidth is an east-west service or a north-south service based on the channel attributes of the uplink channel.

[0072] In a possible embodiment of the present application, in step S120, performing bandwidth allocation related operations according to the service attributes of the first service may also include: when the connection with the OLT fails, stopping forwarding the bandwidth request for the first service to the OLT, and allocating bandwidth to the first service according to a preset bandwidth allocation rule.

[0073] In the case where the connection between the master device and the OLT fails, that is, the master device loses connection with the OLT, in this case, the master device can allocate bandwidth for the first service according to a preset bandwidth allocation rule, such as simple allocation, fixed allocation, or user participation, and the master device stops forwarding bandwidth requests to the OLT.

[0074] Exemplarily, the embodiment of the present application further includes: the master device forwards the bandwidth allocation result returned by the OLT to the slave device, so that the slave device obtains the allocated bandwidth.

[0075] The method provided in the embodiment of the present application may further include the following steps S210-S230:

[0076] Step S210: receiving a service message of a second service sent by a home user device;

[0077] Step S220: Obtain the destination address of the service message;

[0078] Step S230: When the destination address of the service message belongs to the address of a stored home user device, determine that the service attribute of the service message is an east-west attribute, determine the target slave device according to the destination address of the service message, and forward the service message to the target slave device through the first downlink channel, wherein the channel attribute of the first downlink channel is an east-west attribute.

[0079] Exemplarily, the first downlink channel may be a GEM Port.

[0080] The OLT can configure one or more downstream channels for the master device to establish one or more east-west downstream channels between the master device and the slave device. These downstream channels can be GEM ports. The master device maps the downstream service frame to the downstream channel with matching attributes to transmit the downstream service frame to the slave device through the downstream channel.

[0081] Exemplarily, after step S220, the method of the embodiment of the present application may further include the following step S240:

[0082] Step S240: When the destination address of the service message does not belong to the stored address of the home user device, determine that the service attribute of the service message is a north-south attribute, and forward the service message to the OLT with equal delay.

[0083] Exemplarily, the master device may construct a user device address list locally to store the addresses of home user devices. When receiving a service message from a user device, the service attribute of the service message may be determined based on whether the destination address in the service message is stored in the home user device address list. Specifically, if the master device can find the destination address in the local home user device address list, the service attribute is determined to be an east-west attribute, otherwise it is a north-south attribute.

[0084] Before step S210, the method of the embodiment of the present application may further include the following steps S201 and S202:

[0085] Step S201, obtaining and storing the address of at least one home user device with which a connection has been established;

[0086] Step S202: Send the address of the home user equipment to the slave device via a downlink notification message, so that the slave device stores the address of the home user equipment.

[0087] The master device can request an address from a home user device with which a connection has been established, store the acquired address locally, and send the address of the home user device to the corresponding slave device via a downlink notification message to share the learned home user device address with the slave device.

[0088] The following is explained by an example. In one example of the present application, the following steps S301-S305 are included:

[0089] Step S301, the main device 1 receives a connection request from the home user device 1, establishes a connection with the home user device 1, and obtains the address address1 of the home user device 1;

[0090] Step S302: the master device 1 stores the address address1 of the home user device 1 in the local home user device address list;

[0091] Step S303: The master device 1 generates a downlink notification message "Device_Address_Share_d", and the downlink notification message "Device_Address_Share_d" carries the address address1 of the home user device 1;

[0092] Step S304, the master device 1 sends a downlink notification message "Device_Address_Share_d" to the slave devices 1, 2 and 3, and correspondingly, the slave devices 1, 2 and 3 receive the downlink notification message "Device_Address_Share_d" sent by the master device 1 respectively;

[0093] Step S305, slave device 1, slave device 2 and slave device 3 respectively obtain the address address1 of home user device 1 from "Device_Address_Share_d", and store the address address1 of home user device 1 in the local home user device address list.

[0094] Exemplarily, the format of the downlink notification message "Device_Address_Share_d" may refer to the following Table 1.

[0095] Table 1

[0096] byte Fields illustrate 1-2 ONU-ID Indicates the ONU-ID of all receivers of the broadcast message 3 Message Type ID The value is 0x20, indicating the "Device_Address_Share_d" message 4 SeqNo 8-bit broadcast PLOAM message sequence number 5-10 address 6-byte MAC address 11 Source ONU-ID When the value is 0xFF, it indicates the master device. Other values ​​indicate the ONU-ID of the slave device. 12-40 Padding Set to 0x00 by the transmitter and regarded as "don't care" by the receiver 41-48 MIC Indicates that the default PLOAM integrity key is used for message integrity check

[0097] Before step S210, the method of the embodiment of the present application may further include the following steps S203 and S204:

[0098] Step S203: receiving an uplink notification message sent by the slave device, wherein the uplink notification message carries an address of a home user device connected to the slave device;

[0099] Step S204: storing the address of the home user equipment carried in the uplink notification message;

[0100] Step S205: Send the address of the home user device to other slave devices except the slave device that sends the uplink notification message through a downlink notification message, so that the other slave devices store the address of the home user device.

[0101] The master device may receive the home user device address shared by the slave device through an uplink notification message, and share the home user device address with other slave devices through a downlink notification message.
