Description

Technical Field

[0001] This invention relates to the field of information technology, and in particular to a PON port rate configuration method, apparatus, and electronic device. Background Technology

[0002] Currently, PON (Passive Optical Network) technology has become the mainstream technology for home broadband and is increasingly being applied in industrial control and vehicle communication. However, in these emerging application areas, with the increasing complexity of communication scenarios, users' requirements for high bandwidth, low latency, and low latency jitter are also becoming more stringent. To meet the demand for high bandwidth, the industry generally upgrades PON networks, such as from GPON (Gigabit Passive Optical Network) to XGPON (10-Gigabit-capable Passive Optical Network) or XGSPON (10-Gigabit-capable Symmetric Passive Optical Network), or, in future applications, using even higher-speed passive optical networks. In this context, PON networks will exhibit various networking scenarios with different speeds, especially in vehicle networks, where uplink and downlink speeds need to be configured differently for different usage scenarios.

[0003] With the rapid development of PON network technology, supporting various uplink and downlink speeds in diverse application scenarios such as home broadband, local area networks (LANs), industrial control, and vehicle networks remains a challenge. For example, in a LAN PON network, the upstream and downstream connections may have different bandwidth requirements, resulting in different uplink and downlink speeds.

[0058] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0059] The following is in conjunction with the appendix Figure 1-8 Exemplary embodiments of the invention will be described more fully here.

Rather, these exemplary embodiments are provided to make the invention more comprehensive and complete, and to facilitate a full communication of the inventive concept to those skilled in the art.

[0060] Subject to the technical concept of this invention, the features, structures, characteristics or other details described in a particular embodiment may be combined in one or more other embodiments in a suitable manner.

[0061] In the description of specific embodiments, the features, structures, characteristics, or other details described in this invention are intended to enable those skilled in the art to fully understand the embodiments.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0063] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0064] The terms “and / or” or “and / or” include all combinations of any one or more of the listed items.

[0065] Figure 2 This is a schematic diagram illustrating the principle of a PON port rate configuration method provided in an embodiment of this specification. The method may include:

[0066] S110: Obtain the PON port rate;

[0067] S120: Configure different optical signal encoding modes for the PON port based on the PON port rate;

[0068] In the specific implementation of this specification, for PON ports, the physical characteristic of optical rate is essentially uniform; that is, the basic rate of the optical signal is constant during actual operation of each port. Therefore, the data transmission and reception rate of the PON port can be modified by using different optical signal encoding modes, meaning that the amount of data information carried at the same optical signal rate can vary. Specifically, assuming the actual rate of the PON port is 1.244g, its optical signal encoding mode is PAM0; then, according to the proportional relationship, the optical signal encoding mode at an actual rate of 4.97664g should be PAM4.

[0069] S130: Based on the high-speed serial communication interface model, the serial data of the PON port with different optical signal encoding modes is converted into parallel data, and the bit width of the parallel data is adjusted based on the PON port rate.

[0070] Optionally, the high-speed serial communication interface model includes the SerDes model.

[0071] In the specific implementation described in this specification, SerDes (Serializer / Deserializer) is a mature communication technology that converts parallel data into serial data for transmission and restores the serial data to parallel data at the receiving end. It is primarily used to reduce the number of physical connections required for transmission, thereby improving data transmission speed and efficiency.

[0072] Optionally, the conversion of serial data from the PON port with different optical signal encoding modes into parallel data based on the high-speed serial communication interface model includes:

[0073] The SerDes model includes a serializer and a deserializer;

[0074] At the transmitting end, the parallel data is converted into serial data by the serializer;

[0075] At the receiving end, the serial data is converted into new parallel data by the deserializer.

[0076] In the specific implementation of this specification, at the transmitting end, parallel data is precisely converted into a corresponding serial data stream according to a predetermined rate mode using advanced serializer technology. The different rate settings directly affect the bit width configuration of the parallel data during serialization, ensuring data integrity and efficient transmission. Correspondingly, at the receiving end, the deserializer accurately converts the received serial data back into parallel format according to preset rate and bit width parameters to meet the needs of the backend processing system.

[0077] S140: Based on the bit width of the parallel data, the corresponding identification delimiter is identified by the sliding code, thereby determining the position of the payload;

[0078] In the specific implementation of this specification, the identification logic is dynamically adjusted according to the currently configured data bit width to ensure that the delimiter identification can be completed accurately under different rates and bit widths. This greatly enhances the system's compatibility and scalability, enabling the PON network to easily cope with various rate and bandwidth requirements that may arise in the future.

[0079] After successfully identifying and delimiting the data, the system further realizes intelligent splicing of multiple data with different bit widths. This is done to integrate data segments from different rate channels with different bit widths into a unified data stream, so that subsequent processing modules can parse and process them according to a hierarchical structure similar to the traditional PON protocol. This not only simplifies the data processing flow, but also improves the overall efficiency and stability of the system.

[0080] S150: The parallel data with different bit widths are spliced ​​and parsed to complete the configuration of the PON port rate.

[0081] In the specific implementation of this specification

[0082] Optionally, the step of concatenating and parsing the parallel data with different bit widths to complete the configuration of the PON port rate includes:

[0083] The bus information is determined according to the new parallel data using a dynamic bandwidth allocation model, thereby ensuring that the delay of the bandwidth allocation for the new parallel data is the same.

[0084] In the specific implementation of this specification, given that a PON port needs to support flexible configuration of different uplink and downlink rates, and these different rates may involve multiple protocol standards such as GPON, XGPON, and 50G-PON, a common protocol format is required to ensure that the device can successfully register, interact with services, and communicate data under various configurable rate environments. Specifically, a protocol encapsulation layer is designed, located between the physical layer and higher-layer protocols, responsible for uniformly encapsulating data frames under different PON protocol standards. During the encapsulation process, the original data frame (whether in GPON, XGPON, or 50G-PON format) is converted into an intermediate representation containing necessary metadata (such as protocol type, rate identifier, frame length, etc.) to ensure that subsequent processing modules can recognize and correctly process this data. The protocol encapsulation layer decouples the rate from the protocol standard. This means that regardless of the uplink and downlink rates of the PON port, the encapsulation layer can adjust the encapsulation strategy according to the current rate setting without changing the internal protocol format. Thus, even if the rate changes, the system can maintain compatibility with multiple protocol standards. Standardized message formats and interaction protocols are employed to ensure that devices with different speeds and protocol standards can communicate according to the same rules. A dynamic protocol adaptation mechanism allows the system to dynamically select the appropriate parser and processor to process data based on the protocol type identifier and speed information in the received data frames. This ensures that even when new protocol standards or speed configurations are encountered during network operation, the system can quickly adapt and handle them correctly.

[0085] The parallel data converted by SerDes is treated as a bus signal with flexibly configurable bit width. This elevates the flexibility of the data flow to a new level, enabling the system to dynamically adjust the data bit width according to actual needs, thereby maximizing the utilization of available bandwidth resources while ensuring consistency in bandwidth allocation latency.

[0086] Optional, also includes:

[0087] When the uplink bandwidth requirement is less than the downlink bandwidth requirement, configure the uplink PON port rate to 2.488g and the downlink PON port rate to 9.976g.

[0088] In the specific implementation of this specification, such as Figure 3 As shown, in an in-vehicle network environment, when passengers engage in entertainment activities such as watching videos and listening to music, network traffic exhibits characteristics of relatively low uplink bandwidth demand and significantly increased downlink bandwidth demand. For this specific application scenario, PON (Passive Optical Network) technology can be adopted, and by rationally configuring the PON port rates of the OLT (Optical Line Terminal) and ONU (Optical Network Unit), this difference in bandwidth demand can be efficiently met. Assuming the uplink rate is configured to 2.488Gbps (i.e., 2.488Gbit / s, or an approximation of 2.5Gbps, commonly found in Ethernet standards), and the downlink rate is configured to 9.976Gbps, this configuration strategy directly addresses the characteristics of low uplink bandwidth demand and high downlink bandwidth demand. Under this configuration, the PON ports of the OLT and ONU will transmit data at the set rates, ensuring that a large amount of downlink data, such as video and audio streams, can be smoothly transmitted to the in-vehicle equipment, while maintaining low-latency transmission of uplink control signals and a small amount of uplink data.

[0089] Optional, also includes:

[0090] When the uplink bandwidth requirement equals the downlink bandwidth requirement, both the uplink PON port rate and the downlink PON port rate are configured to 2.488g.

[0091] In the specific implementation of this specification, such as Figure 4As shown, in an in-vehicle network environment, when passengers engage in activities such as gaming and video calls, network traffic typically exhibits characteristics where uplink and downlink bandwidth requirements are roughly equal. This necessitates a symmetrical bandwidth configuration to support these real-time interactive applications. For this scenario, the uplink and downlink rates of the PON ports of both the OLT and ONU in the PON network are configured to 2.488Gbps (or approximately 2.5Gbps). With this symmetrical rate configuration, the network can efficiently handle both uplink and downlink data streams simultaneously, ensuring real-time transmission of game data, smooth video calls, and potential file sharing needs. Because the uplink and downlink bandwidths are identical, the network will not experience data transmission obstruction in one direction due to excessive data traffic in the other, thereby improving overall network performance and user experience.

[0092] Optional, also includes:

[0093] When the uplink bandwidth requirement is greater than the downlink bandwidth requirement, configure the uplink PON port rate to 9.976g and the downlink PON port rate to 2.488g.

[0094] In the specific implementation of this specification, such as Figure 5 As shown, in vehicular networks, when cameras are operating, especially when high-definition or ultra-high-definition cameras are transmitting video streams, there is a working mode with high uplink bandwidth requirements and low downlink bandwidth requirements. This is because cameras need to upload captured video data to servers or processing centers in real time, while downlink data may mainly consist of control signals or a small amount of feedback information. To address this scenario, the PON ports of the OLT and ONU in the PON network are configured with an uplink rate of 9.976Gbps and a downlink rate of 2.488Gbps. This configuration ensures that cameras can efficiently transmit large amounts of video data to other parts of the network while maintaining low downlink bandwidth requirements, thus saving bandwidth resources and reducing the risk of network congestion.

[0095] In this invention, the uplink and downlink rates of the PON port are flexibly configured according to the bandwidth requirements of different application scenarios; the bit width of parallel data is adjusted by adjusting the PON port rate, and dynamic bandwidth allocation is used to ensure efficient use of bandwidth resources; a high-speed serial communication interface model is used to convert data between serial and parallel modes, which enables fast data transmission and processing. This helps to reduce data transmission latency and improve real-time performance, which is especially important for applications that require low latency, such as video calls and games.
