[0002] This application claims priority to Chinese patent application filed on August 1, 2024, application number 2024110517164, entitled "Network Communication Method, Apparatus, Computer Equipment and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of optical communication technology, specifically to a network communication method, apparatus, computer equipment, and storage medium. Background Technology

[0004] In the high-bandwidth, non-blocking transmission mode of PON (Passive Optical Network), the forwarding time of OLT (Optical Line Terminal) and ONU (Optical Network Unit) devices, as well as the downlink (broadcast) forwarding delay jitter, are relatively small and essentially constant. Therefore, timeliness guarantees in PON networks mainly focus on the uplink. Existing uplink communication primarily employs the TDMA (Time Division Multiple Access) multiplexing mechanism. The OLT device is responsible for allocating uplink time slots for service bursts in the logical channels (Traffic Containers, TCONTs) of the ONU devices. The ONU devices can only send uplink data within the uplink time slots allocated by the OLT device, and the length of the uplink time slot is directly related to the bandwidth configured for that logical channel.

[0005] The existing methods for reducing uplink latency in PON networks are as follows: Since the standard defines each uplink time slot allocation frame as 125 microseconds, to reduce uplink latency, the uplink time slot allocation frequency of each uplink time slot allocation frame is generally increased. Theoretically, each uplink time slot allocation frame can allocate 16 bursts, which means 16 uplink time slots can be allocated. In this case, the minimum latency between bursts can reach 125 / 16 = 7.8125 microseconds.

[0006] However, due to various factors (e.g., each service burst requires a preamble, introducing a certain fixed overhead time, and the uplink time slots allocated to service bursts on different logical channels may differ, as well as varying service volumes), the number of bursts in the uplink time slot allocation frame may be less than 16. Limited by the current time slot allocation mechanism of PON networks (as shown in Figure 1), service bursts are generally configured at the front end of the uplink time slot allocation frame, resulting in the uplink time slots allocated to service bursts not filling the entire 125 microsecond period; even if N bursts are allocated, the latency will be greater than 125 / N microseconds. This leads to the problem of large uplink communication latency and an undetermined upper limit for latency. Summary of the Invention

[0028] If the required time slot for a single operation is less than the duration of a single operation, then the required time slot for a single operation is configured in each operation time slot, and the duration of a single operation is updated.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] As shown in Figure 1, in the uplink of existing PON networks, service bursts in each uplink time slot allocation frame are generally configured at the front end of the uplink time slot allocation frame. The single-frame latency is determined based on the maximum latency in that uplink time slot allocation frame. For example, taking a frame containing 4 bursts, the theoretically optimal single-frame latency should be 125µs / 4 = 31.25µs. However, due to the existing service burst allocation mechanism, service bursts are concentrated at the front end of the uplink time slot allocation frame, resulting in a maximum single-frame latency much greater than 31.25µs. In other words, when the uplink time slots allocated for a service burst cannot fill the entire 125-microsecond period, even with N bursts, the latency will still be greater than 125 / N microseconds. This leads to a large uplink communication latency and an undetermined upper limit for latency in the existing network. In Figure 1, A in the uplink time slot allocation frame represents a service burst generated by an existing service based on the corresponding logical channel within the uplink time slot allocation frame. B represents a service burst generated in the uplink timeslot allocation frame based on the corresponding logical channel of another existing service. Each existing service has a corresponding logical channel.

[0058] The network communication method provided in this application embodiment can be applied to the application environment shown in Figure 2. It is mainly applied in the PON network shown in Figure 2, and can be executed by the OLT device in the PON network, or by the OLT device interacting with the control device in the PON network. This application does not specifically limit the executing entity of the network communication method. Specifically, when the PON network performs network communication, especially in uplink communication, it determines the placeholder time slot information corresponding to the uplink time slot allocation frame based on the number of service bursts and the single burst time slot in the existing service in the uplink time slot allocation frame. The placeholder time slot information includes the number of placeholder time slots and the single placeholder duration. Based on the placeholder time slot information, placeholder time slots are added between service bursts in the uplink time slot allocation frame. The uplink time slot allocation frame after adding placeholder time slots is used for network communication.

[0059] PON (Passive Optical Network) is a single-fiber bidirectional optical access network that adopts a point-to-multipoint (P2MP) structure. It consists of an optical line terminal (OLT equipment) at the central office, an optical distribution network (ODN equipment), and an optical network unit (ONU equipment) at the user side.

[0060] OLT (Optical Line Terminal) equipment is a terminal device used to connect optical fiber trunk lines.

[0061] ONU (Optical Network Unit) devices are mainly divided into active optical network units and passive optical network units. Generally, a device containing an optical receiver, uplink optical transmitter, multiple bridging amplifiers, and network monitoring is called an optical node.

[0062] In one embodiment, FIG3 is a schematic flowchart of a network communication method according to an embodiment of the present application. Taking the application of the method to the OLT device in FIG2 as an example, the method includes the following steps:

[0063] S301, based on the number of service bursts and the single burst time slot of existing services in the uplink time slot allocation frame, determine the occupancy time slot information corresponding to the uplink time slot allocation frame.

[0064] The occupancy time slot information includes the number of occupancy time slots and the duration of a single occupancy. The uplink time slot allocation frame refers to the time-based frame structure in the uplink communication link. Existing services refer to services that have already been configured with logical channels and have had corresponding upper-level time slots allocated in the uplink time slot allocation frame for their respective service bursts. A service burst refers to a high-speed data transmission method generated by an existing service. The OLT device allocates uplink time slots (i.e., single burst time slots) in the uplink time slot allocation frame for service bursts generated by existing services. The burst count refers to the number of service bursts pre-configured in each uplink time slot allocation frame for existing services, such as 4 bursts per frame, 6 bursts per frame, etc. It should be noted that after configuring the burst count, the number of service bursts generated by each existing service in each uplink time slot allocation frame is the same as the burst count. A single burst time slot refers to the duration of the uplink time slot allocated for a service burst. It should be noted that the single burst time slot is the same for each service burst generated by an existing service, and the duration of the single burst time slot is proportional to the bandwidth of the logical channel corresponding to the existing service. The number of placeholder time slots refers to the number of placeholder time slots allocated in the uplink time slot allocation frame. The duration of a single placeholder time slot refers to the duration of each placeholder time slot. A logical channel, also called a traffic container (T-CONT), corresponds to at least one logical channel for each existing service. Logical channels are used to manage and describe the data streams sent and received by each ONU device.

[0065] As an optional implementation of this application, the duration of service bursts generated by existing services in the uplink time slot allocation frame is determined based on the number of bursts and the single burst time slot of existing services. The difference between the allocation frame duration and the duration of occupation in the uplink time slot allocation frame is used as the reserve duration of the placeholder time slot. The placeholder time slot information corresponding to the uplink time slot allocation frame is determined based on the reserve duration of the placeholder time slot and the number of bursts. For example, as shown in Figure 1, the number of bursts generated by existing services (the sum of A and B) is 8. Assuming that the single burst time slot corresponding to each service burst is 8µs, the reserve duration of the placeholder time slot is 125 - 8 * 8 = 61µs. The number of bursts is used as the number of placeholder time slots, that is, the number of placeholder time slots is 8, and the single placeholder duration corresponding to the placeholder time slot is 61 / 8 = 7.6µs.

[0066] Another optional implementation of this application involves determining the duration of service bursts generated by existing services in the uplink time slot allocation frame based on the number of bursts and the time slot of each burst. The difference between the allocation frame duration and the duration of occupation in the uplink time slot allocation frame is used as the reserve duration for the placeholder time slot. The placeholder time slot information corresponding to the uplink time slot allocation frame is determined based on the pre-configured number of placeholder time slots and the reserve duration for the placeholder time slots. For example, as shown in Figure 1, if the number of bursts generated by existing services (the sum of A and B) is 8, and assuming that the time slot of each burst is 8µs, then the reserve duration for the placeholder time slot is 125 - 8 * 8 = 61µs. If the pre-configured number of placeholder time slots is 4, then the single placeholder duration for each placeholder time slot is 61 / 4 = 15.2µs.

[0067] S302, based on the placeholder time slot information, add placeholder time slots between service bursts in the uplink time slot allocation frame. The uplink time slot allocation frame after adding the placeholder time slot is used for network communication.

[0068] As an optional implementation of this application, based on the scheme described in the above embodiments, if the number of occupancy time slots is the same as the number of bursts, then a single-occupancy time slot is added between adjacent service bursts in the uplink time slot allocation frame, and a single-occupancy time slot is added at the end of the service burst that is at the end of the uplink time slot allocation frame.

[0069] As another optional implementation of this application, based on the scheme described in the above embodiments, if the number of occupancy time slots is the same as the number of bursts, then occupancy time slots of a single occupancy duration are added to the front or back of each service burst of the uplink time slot allocation frame.

[0070] As another optional implementation of this application, based on the scheme described in the above embodiments, if the number of occupancy time slots is a preset fixed value, then occupancy time slots of a single occupancy duration are randomly added between adjacent service bursts of the uplink time slot allocation frame until the number of occupancy time slots is fully added.

[0071] The aforementioned network communication method determines the placeholder time slot information corresponding to the uplink time slot allocation frame based on the number of service bursts and the single burst time slot of existing services in the uplink time slot allocation frame. Based on the placeholder time slot information, placeholder time slots are added between service bursts in the uplink time slot allocation frame; the uplink time slot allocation frame with added placeholder time slots is used for network communication. This application determines the placeholder time slot information corresponding to the uplink time slot allocation frame based on the number of service bursts and the single burst time slot of existing services in the uplink time slot allocation frame, and adds placeholder time slots between service bursts in the uplink time slot allocation frame based on the placeholder time slot information. By adding placeholder time slots between service bursts, the latency of each uplink time slot allocation frame can be effectively reduced, thereby significantly reducing the communication latency of the network. Furthermore, based on the placeholder time slot information (i.e., the number of placeholder time slots and the single placeholder duration), the upper bound of the latency can be controlled.

[0072] In one embodiment, the occupancy time slot information corresponding to the uplink time slot allocation frame is determined based on the number of service bursts and the time slot of each burst in the existing service in the uplink time slot allocation frame, including:

[0073] Based on the number of bursts and the logical channel for each existing service to generate a service burst in the uplink time slot allocation frame, each burst group is determined; for each burst group, the group-occupied time slot of the burst group is determined based on the preamble time slot and single burst time slot corresponding to each service burst in the burst group; the occupancy time slot information is determined based on the number of burst groups and the group-occupied time slot of each burst group.

[0074] In one embodiment, each burst group is determined based on the logical channel that generates a service burst in each existing service in the uplink time slot allocation frame according to the burst count and uplink time slot allocation frame, including:

[0075] Based on the logical channel through which each existing service generates a service burst in the uplink time slot allocation frame, and the time sequence between the service bursts, service bursts that are adjacent in time sequence but belong to different logical channels are divided into the same burst group; wherein, the number of service bursts in each burst group is the same as the number of logical channels contained in the uplink time slot allocation frame.

[0076] In one embodiment, the occupancy time slot information includes the number of occupancy time slots and the duration of a single occupancy; the occupancy time slot information is determined based on the number of burst groups and the time slots occupied by each burst group, including:

[0077] The number of groups in the sudden outbreak group is used as the number of time slots for occupancy;

[0078] The duration of a single occupation is determined based on the number of occupation time slots and the time slots occupied by each emergency group.

[0079] In one embodiment, to accurately determine the occupancy time slot information, as shown in FIG4, an optional implementation of S201 includes:

[0080] S401, based on the logical channel of each existing service in the uplink time slot allocation frame that generates a service burst, and the time order between each service burst, service bursts that are adjacent in time order and belong to different logical channels are divided into the same burst group.

[0081] The number of service bursts in each burst group is the same as the number of logical channels contained in the uplink time slot allocation frame.

[0082] Optionally, in this embodiment, based on the logical channel through which each existing service generates a service burst in the uplink time slot allocation frame, and the time sequence between the service bursts, service bursts that are adjacent in time sequence but belong to different logical channels are grouped into the same burst group. For example, as shown in Figure 5, service burst A and service burst B in the uplink time slot allocation frame belong to different logical channels, and service burst A and service burst B are arranged sequentially. Therefore, according to the time sequence, one service burst A and one service burst B are grouped into one burst group.

[0083] S402 uses the number of burst groups as the number of occupancy time slots.

[0084] The number of groups refers to the number of burst groups contained in the uplink time slot allocation frame.

[0085] S403, determine the duration of a single occupation based on the number of occupation time slots and the group occupation time slots of each burst group.

[0086] Among them, the group-occupied time slot refers to the duration of the uplink time slot allocated to each service burst group.

[0087] Optionally, in this embodiment, for each burst group, the group-occupied time slots of the burst group are determined based on the preamble time slots and single burst time slots corresponding to each service burst in the burst group. The total occupied time slots in the uplink time slot allocation frame are determined based on the number of occupied time slots and the group-occupied time slots. The difference between the allocation frame duration of the uplink time slot allocation frame and the total occupied time slots is taken as the total occupation duration. The ratio of the total occupation duration to the number of occupied time slots is taken as the single occupation duration.

[0088] Optionally, in this embodiment, for each burst group, the optional implementation method for determining the group-occupied time slot of the burst group based on the preamble time slot and single burst time slot corresponding to each service burst in the burst group is as follows: since each service burst has a corresponding preamble time slot, the preamble time slot corresponding to each service burst and the single service burst corresponding to each service burst are summed, and the summation result is used as the group-occupied time slot of the burst group.

[0089] Optionally, in this embodiment, the total occupied time slots in the uplink time slot allocation frame are determined based on the number of occupied time slots and the group occupied time slots. As can be seen from the above embodiment, the number of occupied time slots is the same as the number of burst groups. Therefore, the product of the number of occupied time slots and the group occupied time slots is used as the total occupied time slots in the uplink time slot allocation frame.

[0090] In this embodiment, based on the logical channel through which each existing service generates a service burst in the uplink time slot allocation frame, and the time order among the service bursts, service bursts with adjacent time orders but belonging to different logical channels are grouped into the same burst group. The number of burst groups is used as the number of pre-emptive time slots. The duration of a single pre-emptive time slot is determined based on the number of pre-emptive time slots and the time slots occupied by each burst group. This embodiment allows for accurate determination of pre-emptive time slot information.

[0091] Based on the above embodiments, in order to facilitate the addition of placeholder time slots between service bursts in the uplink time slot allocation frame, as shown in Figure 5, an optional implementation of S202 includes:

[0092] As shown in Figure 5, a single-occupancy time slot is added between adjacent burst groups, and a single-occupancy time slot is added at the end of the burst group that is at the end of the uplink time slot allocation frame.

[0093] In this embodiment, by adding a single-time placeholder time slot between adjacent burst groups and adding a single-time placeholder time slot at the end of the burst group at the end of the uplink time slot allocation frame, not only is the single-frame latency effectively reduced, but the upper limit of latency is also partially controllable. For example, if the number of placeholder time slots is N, the upper limit of latency can be controlled to 125µs / N. This method of adding placeholder time slots also facilitates the allocation of corresponding time slots for new services.

[0094] In one embodiment, when new services are added and time slots need to be allocated for the new services, as shown in Figure 6, an optional implementation of a network communication method includes:

[0095] S601, in response to a request to add a service burst for a new service, obtains the time slot required for a single burst of service generated by the new service.

[0096] Among them, "new service" refers to newly added services that require uploading. "Single burst time slot" refers to the single burst duration allocated in the uplink time slot allocation frame for the new service. The single burst time slot is mainly proportional to the bandwidth of the logical channel corresponding to the new service.

[0097] Optionally, in this embodiment, in response to a service burst addition request for a new service, the channel bandwidth of the logical channel corresponding to the new service is obtained. Based on the channel bandwidth, the time slot required for a single service burst generated by the new service is determined. An optional implementation of determining the required time slot for a single service burst based on this bandwidth in this embodiment is to determine the required time slot based on the channel bandwidth and a bandwidth list. The bandwidth list records the mapping relationship between channel bandwidth and the required time slot.

[0098] S602, if the single required time slot is less than the single occupation duration, then configure the single required time slot in each occupation time slot and update the single occupation duration.

[0099] Optionally, as shown in Figure 7 in this embodiment, if the single required time slot is less than the single occupancy duration, then the single required time slot is configured in each occupancy time slot. That is, by reconfiguring each occupancy time slot, the single required time slot for a new service burst can be allocated from each occupancy time slot. In Figure 7, "occupancy" refers to the occupancy time slot. "C" represents the service burst generated by the new service.

[0100] Optionally, in this embodiment, an alternative implementation for updating the single-occupancy duration is to use the difference between the single-occupancy duration and the single-required time slot as the updated single-occupancy duration.

[0101] Optionally, in this embodiment, if the required time slot for a single instance is greater than or equal to the single occupancy duration, a burst add response message is sent to indicate that the service cannot be provided.

[0102] In this embodiment, in response to a service burst addition request for a new service, the single-time slot required for the service burst generated by the new service is obtained. If the single-time slot required is less than the single-time placeholder duration, the single-time slot required is configured in each placeholder time slot, and the single-time placeholder duration is updated. If the single-time slot required is greater than or equal to the single-time placeholder duration, a burst addition response message indicating that service cannot be provided is sent. In this embodiment, based on the placeholder time slots and judgment logic, it can be determined whether service can be provided to the new service. If service can be provided, the corresponding single-time slot required for the service burst generated by the new service can be allocated by configuring the placeholder time slots.

[0103] In one embodiment, as shown in FIG8, another alternative implementation of a network communication method includes:

[0104] S801, based on the logical channel through which each existing service generates a service burst in the uplink time slot allocation frame, and the time order among the service bursts, service bursts that are adjacent in time order but belong to different logical channels are grouped into the same burst group. The number of service bursts in each burst group is the same as the number of logical channels included in the uplink time slot allocation frame.

[0105] S802 uses the number of burst groups as the number of occupancy time slots.

[0106] S803: For each burst group, determine the group-occupied time slot of the burst group based on the preamble time slot and single burst time slot corresponding to each service burst in the burst group.

[0107] S804 determines the total number of occupied time slots in the uplink time slot allocation frame based on the number of occupied time slots and the group occupied time slots.

[0108] S805 uses the difference between the allocation frame duration of the uplink time slot allocation frame and the total occupied time slots as the total occupation duration.

[0109] S806 uses the ratio of the total occupation time to the number of occupation time slots as the single occupation time duration.

[0110] S807 adds a single-occupancy time slot between adjacent burst groups, and adds a single-occupancy time slot at the end of the burst group that is at the end of the uplink time slot allocation frame.

[0111] S808, in response to a request to add a business burst for a new business, obtains the time slot required for a single business burst caused by the new business.

[0112] S809, if the single required time slot is less than the single occupation duration, then configure the single required time slot in each occupation time slot and update the single occupation duration.

[0113] S810 uses the difference between the single-time occupation duration and the single-time required time slot as the updated single-time occupation duration.

[0114] S811 If the time slot required for a single instance is greater than or equal to the single time slot duration, a burst add response message is sent to indicate that service cannot be provided.

[0115] In this embodiment, the placeholder time slot information corresponding to the uplink time slot allocation frame is determined based on the number of service bursts generated by existing services and the time slot of each burst in the uplink time slot allocation frame. Based on the placeholder time slot information, placeholder time slots are added between service bursts in the uplink time slot allocation frame; the uplink time slot allocation frame with added placeholder time slots is used for network communication.
