Description

Technical Field

[0001] This invention relates to the field of wireless communication network technology, and in particular to an FTTR wireless network system and a method for dynamic bandwidth adjustment. Background Technology

[0002] With the popularization of digital life, home users have an increasing demand for high-speed, stable, and fully covered wireless networks. Traditional wireless networking methods often encounter problems such as signal dead zones and speed attenuation when dealing with large houses and houses with complex structures.

[0003] Currently, existing FTTR networking solutions mainly adopt a two-level structure of master and slave optical modems. The master optical modem is connected to the operator's network through the fiber optic cable to the home, and then connected to the slave optical modems deployed in each room through the fiber optic cable laid indoors, thereby achieving wired fiber optic coverage throughout the house. The slave optical modems usually also function as wireless Wi-Fi access points, providing users with room-level wireless access services. This architecture constitutes the mainstream technical solution for achieving gigabit coverage throughout the house.

[0004] However, existing FTTR systems still have significant shortcomings. First, the system lacks intelligent management capabilities. The fiber optic link between the main optical modem and the slave optical modems serves only as a static data channel, unable to monitor and dynamically allocate bandwidth usage in each room in real time, making it difficult to cope with the dynamic bandwidth demands of different rooms and services within a home. Second, the Wi-Fi signal coverage of the slave optical modems is limited. In remote areas such as bathrooms and balconies, or in corners with severe wall obstructions, the signal remains weak, failing to achieve truly seamless coverage. Third, the entire network lacks a unified control core. The main optical modem has limited management functions over the slave optical modems and the wireless network, making it difficult to achieve efficient centralized configuration, status monitoring, and intelligent roaming, thus impacting the user's end-user experience. Summary of the Invention

[0005] This invention provides an FTTR wireless network system to solve the problem that existing technologies lack the ability to perceive and dynamically allocate room channel bandwidth in real time, resulting in large wireless coverage blind spots, which makes it difficult to meet the dynamic service needs of the whole house and achieve a truly seamless roaming experience.

[0006] The first aspect of this invention provides an FTTR wireless network system, comprising: a main optical modem, whose uplink interface is connected to an OLT on the network side via a fiber optic cable; an intelligent optical splitter, whose input is connected to the downlink optical port of the main optical modem; multiple slave optical modems, whose uplink optical ports are connected to the respective outputs of the intelligent optical splitter via split optical fibers; at least one end wireless access point (AP), whose uplink Ethernet port is connected to the downlink Ethernet port of the slave optical modem via a Category 6 Ethernet cable; the intelligent optical splitter is used to monitor the transmission status of each split optical fiber in real time and dynamically allocate bandwidth; the main optical modem performs unified configuration management and status monitoring of all slave optical modems and end wireless APs through its built-in intelligent control unit.

[0007] In one feasible implementation, the intelligent optical splitter includes: an optical splitter whose input end is connected to the downlink optical port of the main optical modem, for distributing downlink optical signals from the main optical modem to multiple output ends; an optical fiber detector disposed on the splitting optical fiber of each output end of the optical splitter, for real-time monitoring of the transmission parameters of each branch optical path; a signal detection unit connected to the optical fiber detector, for collecting and processing the monitoring data of each optical path; and a central control unit connected to the signal detection unit, for generating bandwidth allocation and switching strategies based on the monitoring data.

[0008] A second aspect of the present invention provides a method for dynamic bandwidth adjustment, comprising: acquiring channel data information of each sub-fiber channel, the channel data information including data flow rate, number of connections and service type; calculating the dynamic demand score of each channel based on the channel data information; and sending a configuration command to the OLT through a management interface according to the dynamic demand score, so as to dynamically adjust the bandwidth configuration parameters of the corresponding sub-optical modem.

[0009] In one feasible implementation, the calculation of the dynamic demand score for each channel based on channel data information includes: collecting the historical peak and average traffic values ​​of each channel within a preset time period; identifying the service type corresponding to the currently active connection of each channel and assigning priority weights; and weighting and fusing real-time traffic, historical patterns, and service priorities to output the dynamic demand score.

[0010] In one feasible implementation, the step of sending a configuration instruction to the OLT through a management interface based on the dynamic demand score includes: comparing the dynamic demand score with multiple preset bandwidth level thresholds; determining the guaranteed bandwidth and maximum bandwidth value that the target needs to be allocated from the optical modem based on the comparison results; generating a configuration instruction containing the optical modem identifier and the target bandwidth parameter based on the guaranteed bandwidth and maximum bandwidth value that the target needs to be allocated from the optical modem; and sending the configuration instruction to the OLT through the management interface.

[0011] In one feasible implementation, the method further includes: periodically acquiring the wireless rate and signal strength parameters of each terminal connected from the optical modem; triggering a handover feasibility assessment when the wireless rate of the terminal is detected to be below the experience threshold for a continuous preset time; selecting the target access point with the best signal quality from the candidate access points and guiding the terminal to perform seamless roaming handover.

[0012] In one feasible implementation, guiding the terminal to perform seamless roaming handover includes: coordinating the current service access point and the target access point; sending network-assisted roaming guidance information to the terminal through the current service access point; and the terminal associating with the target access point based on the roaming guidance information to complete the handover.

[0013] In one feasible implementation, the acquisition of channel data information for each sub-fiber channel includes: monitoring the physical layer transmission parameters and data flow rate of each sub-fiber; counting the number of active connections or sessions for each sub-fiber channel; and performing deep packet inspection on the data stream of each sub-fiber channel to identify the service type and assign priority weights.

[0014] In one feasible implementation, the method further includes: monitoring the number of network-connected devices and changes in their MAC addresses throughout the house; generating a security alarm and reporting it to the user terminal when an unknown device is detected accessing the network or the number of connections increases abnormally; and receiving instructions from the user terminal to perform network disconnection or speed limiting on designated devices.

[0015] In one feasible implementation, the method further includes: learning and recording the historical usage patterns of users on the network of each room at different times of the day; pre-allocating higher bandwidth to the optical modem channel of the corresponding room before the start of a specific time period; and automatically reverting to a dynamic allocation mode based on real-time demand after the end of the specific time period.

[0016] The technical solution provided by this invention includes a main optical modem, an intelligent optical splitter, multiple slave optical modems, and at least one end wireless AP. The uplink interface of the main optical modem is connected to the OLT on the network side via the incoming optical fiber. The input end of the intelligent optical splitter is connected to the downlink optical port of the main optical modem. The uplink optical ports of the slave optical modems are connected to the respective output ends of the intelligent optical splitter via split optical fibers. The uplink Ethernet port of the end wireless AP is connected to the downlink Ethernet port of the slave optical modem via a Category 6 Ethernet cable. The intelligent optical splitter is used to monitor the transmission status of each split optical fiber in real time and dynamically allocate bandwidth. The main optical modem performs unified configuration management and status monitoring of all slave optical modems and end wireless APs through its built-in intelligent control unit. In this embodiment of the invention, a hierarchical FTTR system is constructed, consisting of a main optical modem, an intelligent splitter, slave optical modems, and end wireless access points. The intelligent splitter, as the core hub, not only physically distributes the fiber optic signal but also dynamically allocates bandwidth by monitoring the transmission status of each split fiber in real time. This ensures that network resources are accurately and efficiently distributed to different rooms on demand, effectively solving network congestion and lag issues in long-distance rooms and when multiple users simultaneously access high-traffic services. Simultaneously, the main optical modem, as the unified control center, centrally configures and monitors the status of all slave optical modems and end access points flexibly deployed in weak signal areas, forming a unified wireless network that supports seamless roaming and enhancing wireless signal coverage in corner areas of the house. Thus, the system achieves more comprehensive high-speed coverage throughout the house, intelligent bandwidth resource scheduling, and intensive operation and maintenance of network equipment, significantly improving the utilization efficiency, stability, and user experience of the entire house network.

Detailed Implementation

[0018] This invention provides an FTTR wireless network system that uses an intelligent optical splitter to achieve dynamic on-demand scheduling of optical layer bandwidth. Combined with centralized control of the main optical modem and flexible deployment of end APs, it enhances the overall coverage of wireless signals and the utilization efficiency of network resources throughout the house.

[0020] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the FTTR wireless network system in this invention includes: The system consists of a main optical modem, an intelligent optical splitter, multiple slave optical modems, and at least one end wireless access point (AP). The uplink interface of the main optical modem is connected to the OLT on the network side via the incoming fiber optic cable. The input of the intelligent optical splitter is connected to the downlink optical port of the main optical modem. The uplink optical ports of the slave optical modems are connected to the respective outputs of the intelligent optical splitter via split optical fibers. The uplink Ethernet ports of the end wireless APs are connected to the downlink Ethernet ports of the slave optical modems via Cat6 Ethernet cables. The intelligent optical splitter is used to monitor the transmission status of each split optical fiber in real time and dynamically allocate bandwidth. The main optical modem uses its built-in intelligent control unit to perform unified configuration management and status monitoring of all slave optical modems and end wireless APs.

[0021] In this embodiment, a hierarchical FTTR system is constructed, consisting of a main optical modem, an intelligent optical splitter, slave optical modems, and end wireless access points. The intelligent optical splitter, as the core hub, not only physically distributes the fiber optic signal but also dynamically allocates bandwidth by monitoring the transmission status of each split fiber in real time. This ensures that network resources are accurately and efficiently distributed to different rooms on demand, effectively solving network congestion and lag issues in long-distance rooms and when multiple users simultaneously access high-traffic services. Meanwhile, the main optical modem, as the unified control center, centrally configures and monitors the status of all slave optical modems and end access points flexibly deployed in weak signal areas, forming a unified wireless network that supports seamless roaming and enhancing wireless signal coverage in corner areas of the house. Thus, the system achieves more comprehensive high-speed coverage throughout the house, intelligent bandwidth resource scheduling, and intensive operation and maintenance of network equipment, significantly improving the utilization efficiency, stability, and user experience of the entire house network.

[0022] Furthermore, such as Figure 2The image shows another embodiment of the FTTR wireless network system in this invention. The difference between this FTTR wireless network system and the aforementioned system is that the intelligent splitter further includes a splitter, an optical fiber detector, a signal inspection unit, and a central control unit. The input end of the splitter is connected to the downlink optical port of the main optical modem, used to distribute the downlink optical signal from the main optical modem to multiple output ends. The optical fiber detector is installed on the splitting optical fibers at each output end of the splitter, used to monitor the transmission parameters of each branch optical path in real time. The signal inspection unit is connected to the optical fiber detector, used to collect and process the monitoring data of each optical path. The central control unit is connected to the signal inspection unit, used to generate bandwidth allocation and switching strategies based on the monitoring data.

[0023] The core control and data exchange point of the FTTR wireless network system is located in the main optical modem, which is usually deployed in the weak current box or TV cabinet in the living room. The uplink interface of the main optical modem adopts the XG-PON or 10G-EPON standard and is bidirectionally connected to the OLT equipment on the operator's equipment room side through a single-mode fiber optic cable of G.652D or G.657.A1 standard (5) to access the Internet. Its theoretical downlink speed can reach 10Gbps. The downlink side of the main optical modem is equipped with 1 to 2 P2MP (point-to-multipoint) type downlink optical ports, which are directly connected to the input end of the intelligent optical splitter through a short jumper. The main optical modem integrates a key intelligent control unit, which is built on a SoC chip and runs an embedded network operating system. It is responsible for summarizing the status information of the entire network and serves as a unified control center to configure, manage and monitor the status of all subordinate devices. Users can remotely access this unit through a mobile APP via an encrypted channel. The intelligent optical splitter is typically installed in the low-voltage box along with the main optical modem. It contains a physical splitter responsible for evenly distributing the downlink optical signal from the main optical modem to the four output ports. Additionally, the intelligent optical splitter integrates three main functional modules: a fiber optic detector using micro-optical components to bypass and detect the splitting fibers at each output port with a splitting ratio of less than 5%, capable of real-time monitoring of physical layer transmission parameters such as received optical power, optical link loss, and bit error rate of each branch optical path; a signal detection unit that receives raw data from the fiber optic detector and processes it using its built-in processor, real-time parsing the data flow rate and active TCP / UDP session count for each channel, and integrating a deep packet inspection engine to identify the service type of the data flow (e.g., marking video conferencing traffic as high priority); and all monitoring data is aggregated to a central control unit, which is configured to run a bandwidth allocation algorithm. Based on the data provided by the signal detection unit and learned historical patterns, this algorithm calculates the "dynamic demand score" for each channel and generates bandwidth allocation and WiFi switching strategies accordingly. The multiple outputs of the intelligent optical splitter are connected to slave optical modems deployed in different functional rooms via multiple bend-insensitive splitting optical fibers of the G.657.A2 standard. For example, one slave optical modem is set up in each of the living room, master bedroom, secondary bedroom and study. The uplink optical ports of these slave optical modems use SC / APC connectors to connect to the splitting optical fibers. Each slave optical modem integrates a wireless chip that conforms to the Wi-Fi 6 standard, supports 2.4GHz and 5GHz dual-band concurrent operation, and has MU-MIMO technology. Its downlink side provides one or more gigabit / ten-gigabit downlink ports.To enhance wireless signal coverage in corner areas of the house, additional end-point wireless access points (APs) were deployed in areas prone to signal obstruction, such as the kitchen, bathroom, and balcony. The uplink ports of these APs are connected to the downlink ports of the nearest secondary optical modem (ONT) via pre-installed Cat6 cables, thus achieving wired backhaul and ensuring backplane bandwidth. All secondary ONTs and end-point APs are managed by the main ONT's intelligent control unit using a unified protocol and configured to use the same SSID. 802.11k, 802.11v, and 802.11r fast roaming protocols are enabled, collectively forming a seamless wireless roaming network. The entire system achieves end-to-end, intelligent gigabit coverage from the fiber optic entry point to the wireless edge through real-time monitoring and policy execution by the intelligent splitter and centralized management by the main ONT.

[0024] In this embodiment of the invention, a four-level collaborative architecture of "main optical modem - intelligent optical splitter - slave optical modem - end wireless AP" is constructed: the intelligent optical splitter, with the help of its internal fiber detector, signal detection unit and central control unit, monitors the transmission status of each fiber channel in real time and intelligently generates bandwidth allocation strategies, thereby realizing the leap from "static allocation" to "on-demand dynamic scheduling" at the optical layer, effectively solving the bandwidth competition and lag problems under concurrent services in multiple rooms; at the same time, the main optical modem, through its intelligent control unit, manages all slave optical modems and flexibly deployed end APs in a unified manner, forming a centralized control and seamless roaming wireless network, thus forming a unified wireless network that supports seamless roaming and enhancing wireless signal coverage in the corner areas of the house; the system thus achieves more comprehensive high-speed coverage throughout the house, intelligent scheduling of bandwidth resources and intensive operation and maintenance of network equipment, significantly improving the utilization efficiency, stability and user experience of the whole house network.

[0025] Please see Figure 3 One embodiment of the bandwidth dynamic adjustment method in this invention is applied to any of the above-mentioned FTTR wireless network systems. The method includes: 301. Obtain channel data information for each fiber optic channel, including data flow rate, number of connections, and service type; The fiber optic detector in the intelligent optical splitter, as a distributed sensing module, is physically integrated into the fiber optic link after each output port of the splitter. Using micro-optical elements, it performs bypass detection on the fiber optic links at each output port with an extremely low splitting ratio of less than 5%, capturing physical layer transmission parameters in real time, including received optical power, link loss, and bit error rate. These captured raw photoelectric signals first undergo preliminary analog-to-digital conversion and signal conditioning within the fiber optic detector to form standardized digital readings. Subsequently, these digital data are transmitted in real time and in parallel to the signal detection unit within the intelligent optical splitter via its internal data bus. The signal detection unit receives data streams from all channel fiber optic detectors, first analyzing and calibrating these physical layer parameters, and then applying specific algorithms... The data stream is converted into the real-time data traffic rate for each optical fiber. Based on this, the signal detection unit further performs in-depth analysis of the data stream, using state detection technology to count the number of concurrent active TCP / UDP connections or sessions on each channel to accurately assess the network load of that channel. Furthermore, this signal detection unit integrates a Deep Packet Inspection (DPI) engine, capable of real-time analysis of the protocol header and even payload characteristics of data packets, and quickly matching them with a pre-stored feature library of various application protocols to accurately identify the service type. Based on a preset QoS policy, different service types are assigned corresponding priority weights. All these processed data—traffic rate, connection count, service type, and weight—are packaged together into a structured "channel data information" message.

[0026] 302. Calculate the dynamic demand score for each channel based on channel data information; After receiving channel data from the signal detection unit, the central controller in the intelligent splitter calls up stored historical data to analyze the historical peak and average traffic of each channel during the same time period (e.g., 20:00-22:00 in the past week) to identify user habits. Subsequently, the algorithm uses four key dimensions as input variables: real-time data traffic rate, number of active connections, priority weight of identified service types, and historical traffic patterns. Each dimension is assigned a dynamic or static weight coefficient (e.g., the weight of the "real-time traffic" and "service priority" dimensions of an ongoing 4K video stream will be significantly increased due to its high bandwidth and real-time requirements). The data is then fused and calculated using a preset weighting formula. Finally, this calculation process outputs a quantified dynamic demand score for each channel (e.g., a value between 0 and 100). This score intuitively reflects the channel's urgency for network resources in the current and foreseeable future. The higher the score, the more bandwidth resources it needs to guarantee.

[0027] One specific implementation of the preset weighted formula is: Dynamic Demand Score = (W1 × Real-time Traffic Rate Normalized Value) + (W2 × Active Connection Count Normalized Value) + (W3 × Business Priority Weight) + (W4 × Historical Traffic Pattern Coefficient); where W1, W2, W3, and W4 are preset weight coefficients, and W1 + W2 + W3 + W4 = 1. The historical traffic pattern coefficient can be calculated based on the ratio of real-time traffic in the current time period to the historical average traffic for the same period.

[0028] 303. Based on the dynamic demand score, send configuration commands to the OLT through the management interface to dynamically adjust the bandwidth configuration parameters of the corresponding optical modem.

[0029] After calculating the dynamic demand score for each channel, the central control unit compares it with multiple bandwidth level thresholds preset in the system (for example, scores of 0-30 correspond to "Bronze Level", 31-70 to "Silver Level", 71-90 to "Gold Level", and 91-100 to "Platinum Level"). Based on the comparison results, the unit determines the target optical modem whose bandwidth needs to be adjusted and calculates specific resource allocation parameters for it, including guaranteed bandwidth (e.g., 1.2Gbps guaranteed for Platinum Level) and maximum bandwidth. Then, the central control unit generates a structured and standardized configuration instruction, which explicitly includes the device identifier of the target optical modem (such as its logical ID or MAC address) and the aforementioned target bandwidth parameters. This instruction is sent to the OLT device on the operator's equipment room side via the management interface integrated into the smart splitter through the fiber optic network. After receiving the instruction, the OLT dynamically adjusts the bandwidth configuration file of the ONU (i.e., the user-side optical modem) connected to the corresponding port of the smart splitter in its management interface. In this way, the network's total resources are dynamically and in real time allocated to the rooms and services that need them most, thereby achieving optimal resource utilization and an exceptional user experience at the global level.

[0030] Multiple bandwidth level thresholds can be initially preset based on the total network bandwidth and service guarantee requirements. Furthermore, the central control unit can automatically learn and optimize historical dynamic demand scores based on long-term operating data through cluster analysis algorithms (such as K-Means), thereby adaptively adjusting the threshold range of each level.

[0031] In this embodiment of the invention, a smart splitter is used to sense the traffic load, number of connected devices, and service type of each room channel in real time, and dynamically calculates the resource demand score of each channel accordingly. This allows for real-time sensing of network demand fluctuations in each room within the home, and intelligently and dynamically prioritizes the allocation of total bandwidth resources to rooms and services with higher demand. This effectively solves problems such as increased network latency, video stuttering, and game disconnections caused by bandwidth competition in scenarios where multiple users and devices are online simultaneously. It achieves a leap from static bandwidth allocation with a "one-size-fits-all" approach to dynamic resource scheduling that is "on demand, real-time, and precise," greatly improving the utilization efficiency, stability, and user experience of the whole-house network.

[0032] Furthermore, the calculation of dynamic demand scores for each channel based on channel data information includes: collecting historical peak and average traffic values ​​for each channel within a preset time period; identifying the service type corresponding to the currently active connection of each channel and assigning priority weights; and weighting and integrating real-time traffic, historical patterns, and service priorities to output dynamic demand scores.

[0033] Furthermore, based on the dynamic demand score, a configuration instruction is sent to the OLT through the management interface, including: comparing the dynamic demand score with multiple preset bandwidth level thresholds; determining the guaranteed bandwidth and maximum bandwidth value that the target needs to be allocated from the optical modem based on the comparison results; generating a configuration instruction containing the optical modem identifier and the target bandwidth parameter based on the guaranteed bandwidth and maximum bandwidth value that the target needs to be allocated from the optical modem, and sending the configuration instruction to the OLT through the management interface.

[0034] Furthermore, the method also includes: periodically acquiring the wireless rate and signal strength parameters of each terminal connected from the optical modem; triggering a handover feasibility assessment when the wireless rate of the terminal is detected to be below the experience threshold for a continuous preset time; selecting the target access point with the best signal quality from the candidate access points and guiding the terminal to perform seamless roaming handover.

[0035] The main optical modem's intelligent control unit is responsible for periodically acquiring the wireless performance parameters of the terminals reported by each slave optical modem and end wireless AP. When a handover is deemed necessary, the main optical modem acts as the control center, coordinating the current serving AP and the target AP, and guiding the terminal to complete a seamless handover through the standard fast roaming protocol. In addition, network security management and time-based pre-provisioning functions are also handled by the main optical modem's intelligent control unit. Through this precise division of responsibilities, all system components work collaboratively to achieve intelligent management and optimization of the whole-house network.

[0036] Furthermore, guiding the terminal to seamless roaming handover includes: coordinating the current service access point and the target access point; sending network-assisted roaming guidance information to the terminal through the current service access point; and the terminal associating with the target access point based on the roaming guidance information to complete the handover.

[0037] Furthermore, the channel data information of each sub-fiber channel is obtained, including: monitoring the physical layer transmission parameters and data traffic rate of each sub-fiber; counting the number of active connections or sessions of each sub-fiber channel; and performing deep packet inspection on the data stream of each sub-fiber channel to identify the service type and assign priority weights.

[0038] Furthermore, the method also includes: monitoring the number of network-connected devices and changes in their MAC addresses throughout the house; generating security alarms and reporting them to user terminals when unknown devices are detected or the number of connections increases abnormally; and receiving instructions from user terminals to disconnect or limit the network speed of designated devices.

[0039] The main optical modem's intelligent control unit acts as the execution entity, continuously scanning and recording the MAC addresses and connection status of all active devices in the whole-house network, building a whitelist of trusted devices. When an unknown device not on the whitelist attempts to connect, or when an abnormal surge in the total number of network connections is detected within a unit of time (such as the number of new connections exceeding 200% of the historical baseline within one minute), the main optical modem's intelligent control unit immediately generates a security alarm containing device information and risk type, and pushes it to the user's bound mobile APP in real time through an encrypted channel. Users can view alarm details through the APP interface and remotely issue control commands (such as "blacklist this device" or "limit the network speed of children's devices to 1Mbps"). After the main optical modem receives and parses the command, it directly issues control policies to the specified secondary optical modem or end wireless AP, ultimately achieving immediate network disconnection or precise speed limiting for the target device, thereby effectively preventing unauthorized network access, network attacks, and excessive use of children's devices, ensuring the network security and controllability of the home network.

[0040] Furthermore, the method also includes: learning and recording users' historical usage patterns of the network in each room at different times of the day; pre-allocating higher bandwidth to the corresponding room's optical modem channel before the start of a specific time period; and automatically reverting to a dynamic allocation mode based on real-time demand after the specific time period ends.

[0041] The main optical modem's intelligent control unit continuously learns and records the historical average traffic and service type distribution of each room's secondary optical modem channels at different times (e.g., 8:00 PM - 10:00 PM on weekdays) on a weekly basis, building a user behavior model. When the system recognizes that a specific time period (e.g., Friday night's peak gaming period) is approaching, the main optical modem sends a pre-allocation instruction to the intelligent splitter in advance. Based on this, the central control unit of the intelligent splitter pre-allocates a preset high bandwidth quota (e.g., guaranteed bandwidth increased to 1.5Gbps) to the corresponding room's secondary optical modem channels before the start of the time period (e.g., 5 minutes in advance). After the time period ends, the system automatically releases the fixed quota, allowing the bandwidth allocation strategy to seamlessly switch back to a dynamic allocation mode based on real-time traffic monitoring. This achieves zero-wait bandwidth guarantee in periodic high-load scenarios such as live streaming and online meetings, upgrading from passive response to proactive planning and significantly improving the certainty of the experience for critical services.

[0042] In this embodiment, multi-dimensional data such as traffic rate, number of connections, and service type of each fiber optic channel are collected in real time, and historical traffic patterns are integrated to dynamically calculate the demand score of each channel. This enables intelligent bandwidth scheduling and precise allocation based on service priority and actual usage scenarios. Combined with continuous monitoring of terminal wireless performance and seamless roaming guidance, a wired and wireless integrated resource optimization mechanism is formed. At the same time, network security management and predictive bandwidth pre-allocation based on user behavior learning are integrated. Ultimately, this systematically solves the pain points of rigid bandwidth allocation, wireless coverage blind spots, multi-service competition lag, and weak network security management in large residential homes on multiple levels. It achieves a leap from "single static configuration" to "whole-house dynamic intelligent optimization", significantly improving resource utilization, roaming experience, and security management level in complex home network environments.
