This application claims the priority of the Chinese patent application submitted to the State Intellectual Property Office of China on November 30, 2021, with the application number 202111453392.3, and the application name is "A data transmission method, optical sending device and optical receiving device", all of which The contents are incorporated by reference in this application.

technical field

Background technique

As shown in Figure 1, the existing computing power system includes a global server load balancing (GSLB) server 101 and multiple service nodes. Each service node is registered with the GSLB server 101 . For example, if the requesting terminal 102 requests the GSLB server 101 to acquire resources. Then, the request terminal 102 sends a request message to the GSLB server 101 . According to the request message, the GSLB server 101 can determine that the service node 103 has stored the resource requested by the requesting terminal 102 . The GSLB server 101 sends the address of the service node 103 to the requesting terminal 102 . The requesting terminal 102 can obtain the resource from the service node 103 according to the address of the service node 103 .

However, the transmission bandwidth for the service node 103 to send the resource to the requesting terminal 102 is fixed. If the transmission bandwidth is too small, the service node 103 cannot successfully transmit the resource, and if the transmission bandwidth is too large, there is a disadvantage of wasting transmission bandwidth resources.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

The present application provides a data transmission method, and the structure of the computing power system applied to the data transmission method provided in the present application will be described below in conjunction with FIG. 2 . Among them, FIG. 2 is a structural example diagram of an embodiment of the computing power system provided by the present application.

The computing power system shown in this embodiment is applied to a passive optical network (passive optical network, PON). The PON shown in this embodiment may adopt a gigabit-capable passive optical network (GPON) network type, a 10GPON network type, a 40GPON network type, or a 100GPON network type, etc.

The computing power system shown in this embodiment includes a GSLB server 201 . The GSLB server 201 is connected to multiple computing domains. This embodiment does not limit the number of computing power domains connected to the GSLB server 201. This embodiment uses the GSLB server 201 to connect two computing power domains as an example for illustration, that is, the connection between the GSLB server 201 shown in this embodiment Computing power domain 210 and computing power domain 220 . Taking the computing power domain 210 as an example, the computing power domain 210 includes an optical line terminal (optical line terminal, OLT) 211. The computing power domain 210 also includes a plurality of optical network units (optical network units, ONUs) connected to the OLT. The OLT 211 included in the computing power domain 210 and a plurality of ONUs can be connected through an optical splitter. Among them, ONU is also called optical network termination (ONT) in some scenarios, and ONU in this article also includes ONT.

For example, the computing power domain 210 shown in this embodiment includes ONU212, ONU213, etc. connected to the OLT211, and this embodiment does not limit the number of ONUs connected to the OLT211. The computing power domain 220 connected to the GSLB server 201 includes OLT221, and ONU222 and ONU223 connected to the OLT221. For the description of the specific structure of the computing power domain 220, please refer to the description of the specific structure of the computing power domain 210, and details will not be repeated. .

Based on the computing power system shown in Figure 2, the following describes the process of realizing data transmission based on the computing power system in conjunction with the embodiment shown in Figure 3, wherein Figure 3 is the first step of the data transmission method provided by the embodiment of the present application A flow chart of the steps of an embodiment.

Step 301, the ONU sends the first OMCI to the OLT.

Step 302, the OLT receives the first OMCI message from the ONU.

In a computing power domain, for example, taking the computing power domain 210 as an example, the OLT 211 acts as a secondary computing power gateway to manage resources of each ONU in the computing power domain 210 . For this reason, after the ONU in the computing power domain 210 is powered on, it needs to register with the OLT. The ONU sends registration information to the OLT. The registration information carries the media access control layer (media access control, mac) address of the ONU. In order to realize data transmission between the OLT and the ONU, the OLT needs to allocate a first uplink transmission bandwidth to the ONU, and the first uplink transmission bandwidth corresponds to the computing resources that can be allocated by the ONU.

In order to achieve the purpose of the OLT assigning the first uplink transmission bandwidth corresponding to the ONU's computing resources for the ONU, the ONU needs to send a first optical network unit management control interface (ONU management and control interface, OMCI) message to the OLT, the first OMCI The message is used to indicate the allocated computing power resources of the ONU. Wherein, the computing resources that can be deployed by the ONU are generally all or part of the remaining computing resources after subtracting the occupied computing resources from the total computing resources of the ONU; the computing resources can be computing resources or storage resources. Taking the application of ONU to computing tasks as an example, the computing resources that can be deployed in the ONU are not used to execute any computing tasks. Taking the application of ONU to the storage of audio and video files as an example, the storage resources that can be allocated in the ONU have not yet stored any audio and video files. Specifically, the calculation resource is the number of cores and main frequency of the processor of the ONU. ONU storage resources include ONU disk storage capacity, memory capacity, and external storage capacity. The computing power resources may also include chip types included in the ONU. For example, the ONU includes an artificial intelligence (artificial intelligence, AI) chip, a graphics processing unit (graphics processing unit, GPU) chip or a video codec chip, and the like. Taking a GPU chip as an example, due to the unique properties of the GPU chip, the GPU chip is suitable for processing various types of computing tasks. These computing tasks include tasks such as machine learning, deep learning, data mining, and high performance computing.

The way for the ONU to send the first OMCI to the OLT is as follows: first, the ONU establishes an OMCI channel during the process of registering with the OLT. The OLT manages and controls the ONU through the OMCI channel between the OLT and the ONU. For example, in the registration phase, the ONU sends configuration information for requesting establishment of an OMCI channel to the OLT, and the configuration information includes the identification (ONU-ID) and port identification of the ONU, and the like. The OLT creates an OMCI channel between the OLT and the ONU according to the configuration information. After the OMCI channel between the OLT and the ONU is successfully created, the ONU sends the first OMCI message based on the OMCI channel.

It can be known that the OLT shown in this embodiment can receive the first OMCI message from the ONU through the OMCI channel. The format of the OMCI message transmitted by the OMCI channel shown in this embodiment is described below in conjunction with Table 1:

Table 1

The first OMCI message shown in this embodiment may contain N bytes. Among them, the first and second bytes of the OMCI message are the transaction correlation identifier (transaction correlation identifier) field, and the highest bit of this field indicates the priority level of the OMCI. For example, the value of the field transaction correlation identifier is 1, indicating High priority, value 0 means low priority. The third byte of the OMCI message is the message type field, which is used to indicate the message type. The fourth byte of the OMCI message is the device identifier (device identifier) used to indicate the device type of the ONU. The 5th to 8th bytes of the OMCI message are managed entity identifier (managed entity identifier) fields. The 9th to 10th bytes of the OMCI message are the message contents length (message contents length) field. The 11th to (N-4) bytes of the OMCI message are the message contents field. The (N-3) to Nth bytes of the OMCI message are message integrity check (message integrity check) fields. This embodiment does not limit the value of N. For example, N is a positive integer greater than or equal to 16. The value of N can be determined according to the message carried by OMCI.

In this embodiment, an extended message can be set in the message contents field, and the extended message is used to carry the computing resources that can be allocated by the ONU. For example, the extended message includes "DISK: 100GB", and the extended message is used to indicate that the allocated storage space in the disk storage space of the ONU is 100 gigabytes (gigabyte, GB). The extended message includes "AI: 8T@fp16", and the extended message is used to indicate that the 16-bit half-precision floating-point computing power of the AI chip that can be deployed is 8T.

The format of the extended message shown in this embodiment is any format such as javascript object notation (JSON) format or tag length value (tag length value, TLV) format.

Step 303, the OLT allocates the first uplink transmission bandwidth according to the first OMCI message.

In this embodiment, when the OLT receives the first OMCI message from the ONU, the OLT can allocate the first uplink transmission bandwidth according to the first OMCI message. The first uplink transmission bandwidth shown in this embodiment is the uplink transmission bandwidth.

Wherein, the first uplink transmission bandwidth corresponds to the computing resources indicated by the first OMCI message. Specifically, there is a positive correlation between the first uplink transmission bandwidth allocated by the OLT and the size of the computing resources indicated by the first OMCI message. If the computing resources of the ONU indicated by the first OMCI message are greater, then the first uplink transmission bandwidth allocated by the OLT to the ONU is greater. If the computing resource of the ONU indicated by the first OMCI message is smaller, then the first uplink transmission bandwidth allocated by the OLT to the ONU is smaller.

Step 304, the OLT obtains the data volume information of the uplink target data.

The uplink target data shown in this embodiment is the data to be sent by the ONU to the OLT. For example, continue referring to FIG. 2 , the ONU 213 included in the computing power domain 210 has already stored the uplink target data. The requesting terminal needs to obtain the uplink target data stored by the ONU213. Wherein, the requesting terminal may be a device connected to the GSLB server 201 , or the requesting terminal may be an ONU included in any computing power domain connected to the GSLB server 201 . For example, the ONU 223 of the computing power domain 220 shown in FIG. 2 sends the data request message to the GSLB server 201 through the OLT 221 .

In order to obtain the uplink target data, the requesting terminal sends a data request message for requesting the uplink target data to the GSLB server 201 . The data request message carries the identifier of the uplink target data and the address of the requesting terminal. The data request message may be a hypertext transfer protocol (hyper text transfer protocol, HTTP) get message.

The GSLB server 201 has stored the first data list. The first data list includes a correspondence between data identifiers and OLT Internet Protocol (internet protocol, IP) addresses. The GSLB server 201 determines the address of the OLT 211 corresponding to the identification of the uplink target data requested by the requesting terminal according to the first data list. The GSLB server 201 determines that the upstream target data is stored on the ONU connected to the OLT 211 . The GSLB server 201 sends a redirect message to the requesting terminal, where the redirect message includes the address of the OLT 211 . When the requesting terminal receives the redirection message, it can determine that the uplink target data is stored on the ONU connected to the OLT 211 . In order to obtain the uplink target data, the requesting terminal sends the data request message to the OLT211.

OLT 211 has stored the second data list. The second data list includes the corresponding relationship between the identifier of the data and the mac address of the ONU. The OLT 211 determines the mac address of the ONU 213 corresponding to the identification of the uplink target data according to the second data list. The OLT determines that the ONU 213 is the ONU that has stored the upstream target data. The OLT211 sends the data request message to the ONU213, and the ONU213 determines that the uplink target data needs to be sent to the OLT211 according to the identification of the uplink target data included in the data request message.

It should be clear that this embodiment does not limit the type of uplink target data. For example, if the method shown in this embodiment is applied to an audio and video file storage service, then the uplink target data is an audio and video file. As another example, if the method shown in this embodiment is applied to computing services, then the uplink target data is the calculation result obtained after calculation by the computing chip included in the ONU, and the computing chip can be the above-mentioned AI chip, GPU chips etc.

Before the OLT shown in this embodiment receives the uplink target data stored by the ONU, the OLT first needs to obtain the data volume information of the uplink target data. Specifically, during the process of ONU213 registering with OLT211, an OMCI channel has been established between ONU213 and OLT211. When the ONU213 receives the data request message from the OLT211, the ONU213 may send a second OMCI message to the OLT211 through the OMCI channel, and the second OMCI message carries the data volume information of the uplink target data. The data volume information of the uplink target data is related to the data volume of the uplink target data. For example, the data amount information of the uplink target data can be at least one of the flow rate, frame rate, code rate, resolution, rate, peak flow rate, and average flow rate of the uplink target data.

The data volume information of the uplink target data carried in the second OMCI message shown in this embodiment may also include the service type of the uplink target data. For example, the service type of the uplink target data may be a computing service or a video file storage service.

Step 305, the OLT adjusts the first uplink transmission bandwidth to the second uplink transmission bandwidth according to the data volume information of the uplink target data.

The second uplink transmission bandwidth is the transmission bandwidth used by the ONU to send the uplink target data to the OLT. It can be seen from the above that, at the stage when the ONU registers with the OLT, the OLT has allocated the first uplink transmission bandwidth to the ONU. In this embodiment, the OLT can dynamically adjust the first uplink transmission bandwidth to the second uplink transmission bandwidth according to the data volume information of the uplink target data, so that the second uplink transmission bandwidth readjusted by the OLT is more suitable for the transmission of the uplink target data , realizing the flexible adjustment of the second uplink transmission bandwidth between the ONU and the OLT, and effectively improving the utilization rate of the second uplink transmission bandwidth.

A manner in which the OLT determines the second uplink transmission bandwidth may be that the OLT pre-stores an uplink bandwidth allocation list. The uplink bandwidth allocation list includes correspondence between different data amount information and transmission bandwidth. The OLT determines the data volume information of the uplink target data according to the second OMCI message. The OLT can then determine that the transmission bandwidth corresponding to the data volume information of the uplink target data is the second uplink transmission bandwidth by querying the uplink bandwidth allocation list.

Alternatively, the OLT may dynamically determine the second uplink transmission bandwidth according to the data volume information of the uplink target data. The size of the second uplink transmission bandwidth determined by the OLT is positively correlated with the size of the parameters included in the data volume information of the uplink target data, and the parameters included in the data volume information include at least one of the following:

The rate of the target uplink data, the code rate of the target uplink data, the flow rate of the target uplink data, the frame rate of the target uplink data, the peak flow rate of the target uplink data, the average value of the target uplink data flow.

For example, if the OLT determines that the code rate of the upstream target data is relatively large, it means that during the process of transmitting the upstream target data by the ONU, the number of data bits transmitted per unit time is relatively large. Therefore, the OLT can allocate a larger code rate for the upstream target data. The second uplink transmission bandwidth. For another example, if the OLT determines that the frame rate of the uplink target data is relatively high, it means that the ONU needs to transmit the uplink target data through a relatively large transmission bandwidth to ensure the frame rate of the uplink target data and ensure the clarity of the uplink target data.

For another example, if the data volume information of the uplink target data is the service type of the uplink target data. The OLT may allocate a smaller second uplink transmission bandwidth for the uplink target data with the AI type. For another example, the OLT may allocate a larger second uplink transmission bandwidth for audio and video storage services.

In the method shown in this embodiment, the OLT obtains the first OMCI message used to indicate the computing power resources of the ONU through the OMCI channel, which effectively improves the security and efficiency of the ONU reporting the computing power resources to the OLT. This embodiment does not limit the size relationship between the first uplink transmission bandwidth and the second uplink transmission bandwidth. For example, if the first uplink transmission bandwidth allocated by the OLT according to the computing resources of the ONU is relatively small, the uplink target data cannot be satisfied. In order to obtain the second uplink transmission bandwidth, the OLT may expand the first uplink transmission bandwidth according to the requirement of the data volume information. For another example, if the first uplink transmission bandwidth allocated by the OLT according to the ONU's computing resources is relatively large, and the first uplink transmission bandwidth meets the requirements of the data volume information of the uplink target data, there may still be remaining uplink transmission bandwidth , in order to improve the utilization efficiency of the uplink transmission bandwidth resources between the OLT and the ONU, the OLT can reduce the first uplink transmission bandwidth to the second uplink transmission bandwidth, and the reduced second uplink transmission bandwidth can meet the transmission requirements of uplink target data , and can also effectively improve the utilization efficiency of uplink bandwidth resources between the OLT and the ONU. The OLT shown in this embodiment adjusts on the basis of the first uplink transmission bandwidth to obtain the second uplink transmission bandwidth, which improves the efficiency of the OLT in allocating the second uplink transmission bandwidth to the ONU.

The following is an exemplary description of the process in which the OLT allocates the second uplink transmission bandwidth to the ONU:

The OLT can allocate a transmission container (transmission CONT, T-CONT) frame for the ONU according to the data amount information of the upstream target data and the first upstream transmission bandwidth, so as to realize the purpose of the OLT to allocate the second upstream transmission bandwidth to the ONU. The T-CONT is used to carry uplink target data from the ONU. The second uplink transmission bandwidth refers to the frame length of the T-CONT frame allocated by the OLT to the ONU for transmitting uplink target data.

Specifically, if the OLT allocates the T-CONT frame for the ONU according to the computing resources of the ONU, the T-CONT frame has the first frame length (ie, the first uplink transmission bandwidth). According to the data volume information of the uplink target data, the OLT determines that the first uplink transmission bandwidth needs to be expanded, and then the OLT expands the T-CONT frame from the first frame length to the second frame length. It can be seen that the second frame length is greater than the first frame length. Similarly, if the OLT determines that the first uplink transmission bandwidth needs to be reduced according to the data volume information of the uplink target data, then the OLT reduces the T-CONT frame from the first frame length to the third frame length. It can be seen that the length of the third frame is smaller than the length of the first frame. It should be clear that, in this embodiment, the description that the OLT implements the adjustment of the second uplink transmission bandwidth by allocating the frame length of the T-CONT frame is an optional example without limitation. In other examples, the OLT may also use The GPON encapsulation method (G-PON encapsulation method port, GEM) is used as a unit to allocate the second uplink transmission bandwidth, and the OLT can also use the logical link number (logical link identifier, LLID) as a unit to allocate the second uplink transmission bandwidth. For the specific allocation method, refer to the description of the process of the OLT allocating the second uplink transmission bandwidth according to the T-CONT frame, and details are not repeated here.

Step 306, the OLT sends bandwidth allocation information to the ONU.

When the OLT determines to adjust the first uplink transmission bandwidth to the second uplink transmission bandwidth, the OLT sends the bandwidth allocation information to the ONU, where the bandwidth allocation information is used to indicate the second uplink transmission bandwidth. Taking the OLT as an example to adjust the second uplink transmission bandwidth in units of T-CONT frames, the bandwidth allocation information is used to indicate the start time slot and end time slot of the T-CONT frame allocated to the ONU. The bandwidth between the start time slot and the end time slot in the data frame is the second uplink transmission bandwidth allocated by the OLT to the ONU.

Step 307, the ONU sends the uplink target data to the OLT through the second uplink transmission bandwidth.

The OLT can send the uplink target data to the OLT according to the bandwidth between the start time slot and the end time slot (that is, the second uplink transmission bandwidth) indicated by the bandwidth allocation information. When the OLT receives the uplink target data, it can forward the uplink target data to the requesting terminal.

By adopting the method shown in this embodiment, the OLT obtains the first OMCI message used to indicate the computing power resources of the ONU through the OMCI channel, which effectively improves the security and efficiency of the ONU reporting the computing power resources to the OLT. The OLT can dynamically allocate the second uplink transmission bandwidth for the ONU according to the computing resources of the ONU and the data volume information of the uplink target data to be transmitted, effectively improving the flexibility of adjusting the second uplink transmission bandwidth for transmitting uplink target data sex. In the case where the second uplink transmission bandwidth shown in this embodiment can match the computing resources of the ONU, it can also match the transmission of uplink target data. Under the condition that the transmission of the uplink target data is guaranteed, the utilization rate of the uplink bandwidth resource between the OLT and the ONU can also be improved. Moreover, the OLT shown in this embodiment adjusts on the basis of the first uplink transmission bandwidth to obtain the second uplink transmission bandwidth, which improves the efficiency of the OLT in allocating the second uplink transmission bandwidth to the ONU. The second uplink transmission bandwidth dynamically adjusted by the OLT can improve the reliability of uplink target data transmission, and the adjusted second uplink transmission bandwidth can ensure the quality of service (quality of service, QoS) of the transmitted uplink target data.

The embodiment shown in Fig. 3 illustrates the process that the OLT dynamically allocates the second uplink transmission bandwidth for the ONU, so as to realize the process that the ONU realizes uplink target data transmission based on the second uplink transmission bandwidth. A process of allocating the second downlink transmission bandwidth, so as to realize the process of the OLT sending downlink target data to the ONU based on the second downlink transmission bandwidth.

Step 401, the ONU sends the first OMCI to the OLT.

Step 402, the OLT receives the first OMCI message from the ONU.

For the description of the execution process of step 401 to step 402 shown in this embodiment, please refer to step 301 to step 302 in the embodiment corresponding to FIG. 3 , and the specific execution process will not be repeated.

Step 403, the OLT allocates the first downlink transmission bandwidth according to the first OMCI message.

In this embodiment, when the OLT receives the first OMCI message from the ONU, the OLT can allocate the first downlink transmission bandwidth according to the first OMCI message. The first downlink transmission bandwidth shown in this embodiment is the downlink transmission bandwidth.

Wherein, the first downlink transmission bandwidth corresponds to the computing resource indicated by the first OMCI message. Specifically, there is a positive correlation between the first downlink transmission bandwidth allocated by the OLT and the computing resources indicated by the first OMCI message. If the computing resources of the ONU indicated by the first OMCI message are greater, then the first downlink transmission bandwidth allocated by the OLT to the ONU is greater. If the computing resource of the ONU indicated by the first OMCI message is smaller, then the first downlink transmission bandwidth allocated by the OLT to the ONU is smaller.

Step 404, the OLT obtains the data volume information of the downlink target data.

The downlink target data shown in this embodiment is the data to be sent by the OLT to the ONU. The requesting terminal requests the GSLB server 201 to store downlink target data. For this reason, the requesting terminal sends the data storage request message to the GSLB server 201. For the description of the requesting terminal, refer to the description of the corresponding embodiment in FIG. 2 , specifically in this embodiment I won't go into details.

After the GSLB server 201 receives the data storage request message from the requesting terminal, if the GSLB server 201 determines to store the downlink target data through the computing power domain 210 , the GSLB server 201 forwards the data storage request message to the OLT 211 . According to the data storage request message, the OLT 211 can determine the ONU for storing the downlink target data according to the computing resources of the connected ONUs. For example, the OLT 211 can determine the storage space of each ONU according to the first OMCI message from each ONU. If it is determined that the storage space required by the downlink target data is 50 GB, then the remaining storage space of the ONU selected by the OLT 211 in the computing power domain 210 for storing the downlink target data is greater than 50 GB. Optionally, the OLT 211 may be configured with a storage priority list, and the storage priority list may sort the remaining storage space of each ONU included in the computing power domain 210 in descending order. The OLT 211 selects the ONU with the highest priority in the storage priority list as the ONU for storing the downlink target data. For example, the OLT 211 shown in this embodiment selects the ONU 212 for storing the downlink target data.

The manner in which the OLT acquires the data amount information of the downlink target data can be two optional manners as shown below:

Optional method 1. After the OLT receives the downlink target data from the GSLB server, the OLT can obtain the data volume information of the downlink target data according to the downlink target data. For the specific description of the downlink target data data volume information, please refer to Fig. The description of the data amount information of the uplink target data in the embodiment corresponding to 3 will not be described in detail.

Optional way 2, after the GSLB server receives the downlink target data, the GSLB server acquires the data volume information of the downlink target data according to the downlink target data. The GSLB server sends the data volume information of the downlink target data to the OLT.

Step 405, the OLT adjusts the first downlink transmission bandwidth to the second downlink transmission bandwidth according to the data volume information of the downlink target data.

The second downlink transmission bandwidth is the downlink transmission bandwidth used by the OLT to send the downlink target data to the ONU. It can be seen from the above that, at the stage when the ONU registers with the OLT, the OLT has allocated the first downlink transmission bandwidth to the ONU. In this embodiment, the OLT can dynamically adjust the first downlink transmission bandwidth to the second downlink transmission bandwidth according to the data amount information of the downlink target data, so that the second downlink transmission bandwidth readjusted by the OLT can be more suitable for the downlink target data The transmission effectively improves the rate of downlink target data transmission to the ONU, and effectively improves the utilization rate of the bandwidth in the process of the OLT sending the downlink target data to the ONU.

A manner for the OLT to determine the second downlink transmission bandwidth may be that the OLT pre-stores a downlink bandwidth allocation list. The downlink bandwidth allocation list includes correspondence between different data amount information and downlink transmission bandwidth. The OLT determines the data volume information of the downlink target data according to the second OMCI message. The OLT can determine that the transmission bandwidth corresponding to the data volume information of the downlink target data is the second downlink transmission bandwidth by querying the downlink bandwidth allocation list. Alternatively, the OLT may dynamically determine the second downlink transmission bandwidth according to the data volume information of the downlink target data. The size of the second downlink transmission bandwidth determined by the OLT is positively correlated with the size of the parameters included in the data amount information of the downlink target data. For specific instructions, refer to the OLT shown in step 305 corresponding to FIG. The description of the process of information determining the second uplink transmission bandwidth will not be described in detail.

This embodiment does not limit the size relationship between the first downlink transmission bandwidth and the second downlink transmission bandwidth. The data volume information of the target data is required. Therefore, the OLT may expand the first downlink transmission bandwidth to obtain the second downlink transmission bandwidth. For another example, if the first downlink transmission bandwidth allocated by the OLT according to the computing resources of the ONU is relatively large, and the first downlink transmission bandwidth meets the requirements of the data volume information of the downlink target data, there may also be transmission bandwidth In addition, in order to improve the utilization efficiency of downlink bandwidth resources between the OLT and the ONU, the OLT can reduce the first downlink transmission bandwidth to the second downlink transmission bandwidth, and the reduced second downlink transmission bandwidth can meet the transmission of downlink target data It can also effectively improve the utilization efficiency of downlink bandwidth resources between the OLT and the ONU. Moreover, the OLT shown in this embodiment adjusts on the basis of the first downlink transmission bandwidth to obtain the second downlink transmission bandwidth, which improves the efficiency of the OLT in allocating the second downlink transmission bandwidth.

Specifically, in order to realize the adjustment of the second downlink transmission bandwidth, the OLT may allocate a GEM frame for transmitting the downlink target data to the ONU according to the data volume information of the downlink target data and the first downlink transmission bandwidth. The quantity and length of the GEM frames allocated by the OLT are the second downlink transmission bandwidth.

Step 406, the OLT sends downlink target data to the ONU through the second downlink transmission bandwidth.

Continuing to refer to FIG. 2 , the OLT 211 sends the GEM frame carrying the downlink target data to all ONUs connected to the OLT 211 such as the ONU 212 and the ONU 213 by broadcasting. When OLT211 determines that ONU212 is the ONU used to store the downlink target data, then OLT211 sends the target GEM frame mark to ONU212, and the target GEM frame mark is used to indicate the start time slot and the end time slot of the GEM frame carrying the downlink target data . According to the target GEM frame ID, the ONU 212 decapsulates the downlink target data from the GEM frame at the start time slot and the end time slot indicated by the target GEM frame ID.

By adopting the method shown in this embodiment, the OLT obtains the first OMCI message used to indicate the computing power resources of the ONU through the OMCI channel, which effectively improves the security and efficiency of the ONU reporting the computing power resources to the OLT. The OLT can dynamically allocate the second downlink transmission bandwidth according to the computing resources of the ONU and the data volume information of the downlink target data to be transmitted. It can be seen that, when the second downlink transmission bandwidth shown in this embodiment can match the computing power resources of the ONU, it can also match the transmission of downlink target data. Under the condition that the transmission of downlink target data is guaranteed, the utilization rate of downlink bandwidth resources between the OLT and the ONU can also be improved. Moreover, the OLT shown in this embodiment adjusts on the basis of the first downlink transmission bandwidth to obtain the second downlink transmission bandwidth, which improves the efficiency of the second downlink transmission bandwidth allocated by the OLT. The second downlink transmission bandwidth dynamically adjusted by the OLT can improve the reliability of downlink target data transmission, and the adjusted second downlink transmission bandwidth can guarantee the QoS of the transmitted downlink target data.
