[0002] Currently, the opening of a dedicated line requires multiple steps, including business acceptance, resource verification, allocation and configuration, etc. When opening a dedicated line, a customer looks for a device that can open a dedicated line for the customer. The device is stored in a machine room, and the two ends of the optical cable are connected to the machine room and the optical distribution box. The customer's location is usually the machine room. If the machine room is regarded as a point, starting from this point, the device that meets the business can pass through countless machine rooms and devices, and finally a corresponding dedicated line opening scheme is generated.

[0052] Example 1:

[0053] This embodiment provides a dedicated line activation scheme output method, such as... Figure 1 As shown, the method includes:

[0054] Step S101: Receive the service information corresponding to the leased line product that the user selects and / or enters through the front-end page.

[0055] It should be noted that the service information corresponding to leased line products may include: product name, service configuration mode, installation address, order number, number of optical fiber cores, customer name, circuit speed, interface type, main header port, VLAN (Virtual Local Area Network), whether to bypass the data center, whether to bypass equipment, and whether to bypass optical fiber. The product name may include: Ethernet leased line, Internet LAN (Local Area Network) leased line, ordinary Internet leased line, UTN (Universal Transport Network) leased line, cloud leased line, Ethernet leased line (cross-domain), MPLS (Multi-Protocol Label Switching) / VPN (Virtual Private Network) (cross-domain), MPLS_VPN, cloud networking, government and enterprise premium network, OTN (Optical Transport Network) intelligent network leased line, low-latency leased line, OTN / PEOTN (Packet Enhanced Optical Transport Network) main equipment networking, voice digital trunk, SIP (Session) Initiation Protocol (IP), relay, etc.

[0056] Specifically, users input and / or select the service information corresponding to the leased line product they need to activate through the front-end operation page, and the system receives the service information corresponding to the leased line product they need to activate.

[0057] Step S102: Based on the business information, multiple processors in the chain of responsibility mode sequentially verify and filter the data center, equipment, ports, and fiber optic resources, starting from the initial data center for leased line activation, and output a leased line activation scheme that includes the path for leased line activation and / or equipment and port information. The chain of responsibility mode connects multiple processors into a chain, so that the leased line activation request is processed layer by layer in a preset order. The multiple processors include a data center processor, an equipment processor, a port processor, and a fiber optic processor.

[0058] In this embodiment, to address the problem that existing dedicated line activation schemes rely on manual configuration and output, resulting in low activation efficiency and a high risk of errors, a chain-of-responsibility model is used. The data center processor, equipment processor, port processor, and fiber optic processor sequentially verify and screen the data center, equipment, port, and fiber optic resources starting from the initial data center. This replaces the manual output of the corresponding dedicated line activation scheme, avoids errors that may occur when manually outputting the scheme, and improves activation efficiency.

[0059] In one optional embodiment, the service information includes the number of optical fiber cores, circuit speed, and port type. Based on the service information, multiple processors in a chain-of-responsibility model sequentially verify and filter the equipment room, equipment, ports, and optical fiber resources, starting from the initial equipment room for leased line activation, and output a leased line activation scheme that includes the path and / or equipment and port information for leased line activation. Specifically, this includes:

[0060] The data center processor searches for data centers within the local station range of the installation address that meet the preset data center network level attributes or data center type attributes as the starting data center, and determines whether there are any idle devices in the starting data center.

[0061] In response to the availability of idle equipment in the starting equipment room, the device processor and port processor select the equipment and port in the starting equipment room for dedicated line activation based on the circuit speed and port type, and output the dedicated line activation scheme.

[0062] In response to the absence of idle equipment in the starting equipment room, the fiber optic processor selects an effective path to all other equipment rooms based on the fiber optic topology information of the starting equipment room and the number of fiber cores in the fiber optic cable. The first other equipment room with idle equipment to which the effective path is connected is designated as the termination equipment room. The shortest path from the starting equipment room to the termination equipment room is obtained based on a preset shortest path algorithm. The device processor and port processor select the equipment and ports for dedicated line activation in the termination equipment room based on the circuit speed and port type, and output the dedicated line activation scheme.

[0063] Specifically, the data center processor queries the data centers within the local station range of the installation address that meet the preset data center network level attributes or data center type attributes as the starting data center. It then determines whether there is any idle equipment in the starting data center. If there is idle equipment in the starting data center, the device processor and port processor select the equipment and ports for the leased line activation in the starting data center based on the circuit speed and port type corresponding to the leased line product to be activated, and output the corresponding leased line activation scheme. For example, the output format of the above leased line activation scheme can be: [Starting Data Center] → Transmission Equipment / Interface Type in the Starting Data Center.

[0064] It should be noted that the plurality of processors also includes a station processor; the service information also includes the installation address; the station range to which the installation address belongs is the installation address corresponding to the leased line product to be opened as needed, which is located by the station processor.

[0065] Specifically, if there is no idle equipment in the starting equipment room, the fiber optic processor selects an effective path to all other equipment rooms based on the fiber optic topology information of the starting equipment room and the number of fiber cores corresponding to the leased line product to be activated. The first other equipment room with idle equipment to which the effective path is connected is designated as the termination equipment room. Then, the shortest path from the starting equipment room to the termination equipment room is obtained based on a preset shortest path algorithm, preferably Dijkstra's algorithm. The device processor and port processor select the equipment and ports for leased line activation in the termination equipment room based on the circuit rate and port type corresponding to the leased line product to be activated, and output the corresponding leased line activation scheme. For example, the output format of the above leased line activation scheme can be: [Starting equipment room → Other equipment rooms → Other equipment rooms → Termination equipment room] → Transmission equipment / interface type in the termination equipment room.

[0066] In an optional embodiment, the step of using the data center processor to find a data center that meets the preset data center network level attribute or data center type attribute from the data centers within the local station range of the installation address as the starting data center specifically includes:

[0067] The data center processor queries the data centers within the local station range of the installation address to find the data center with the network layer attribute value as the metropolitan area user terminal.

[0068] If the value of the network layer attribute is found to be the data center of the metropolitan area user terminal, then the data center processor will use the data center of the metropolitan area user terminal as the starting data center.

[0069] If no data center with a network layer attribute value of metropolitan area user terminal is found, the data center processor will search for data centers within the local station range of the installation address whose network layer attribute value is metropolitan area access data center, POP (Point of Presence) point, metropolitan area aggregation data center, metropolitan area core data center, or backbone core data center, and whose data center type attribute value is fixed network access data center, and then use the fixed network access data center as the starting data center.

[0070] Specifically, the data center processor queries the data centers within the local station range of the installation address. The data center with the network layer attribute value of "Metropolitan Area User Terminal" is used as the starting data center, which is the client data center. If no client data center is found, the data center with the network layer attribute value of "Metropolitan Area Access Data Center", "POP Point", "Metropolitan Area Aggregation Data Center", "Metropolitan Area Core Data Center", or "Backbone Core Data Center" and the data center type attribute value includes "Fixed Network Access" is used as the starting data center. Among them, the leased line service speed opened by the metropolitan area core data center and the backbone core data center must meet the preset standard range. The preset standard range is preferably greater than or equal to 100M and less than or equal to 1G.

[0071] In an optional embodiment, the step of selecting the devices and ports for the leased line in the starting equipment room based on the circuit speed and port type via the device processor and port processor specifically includes:

[0072] The equipment in the initial computer room is sorted by the equipment network element number through the equipment processor;

[0073] For each sorted device, the device processor checks whether the uplink transmission segment of the device meets the circuit rate.

[0074] In response to the uplink transmission segment of the device meeting the circuit rate, the port processor checks whether the device has a free port;

[0075] In response to the device having a free port, the port processor checks whether there is a port of the specified port type among the free ports;

[0076] If a port of the specified port type is available among the available ports, then the device and port are selected as the device and port for leased line activation.

[0077] Specifically, the device processor sorts the idle devices in the initial equipment room according to the network element number. The sorting method can be from largest to smallest or smallest to largest network element number. For each idle device in the initial equipment room after sorting, the device processor checks whether the current device's uplink transmission segment has enough transmission time slots to meet the circuit rate corresponding to the leased line product to be activated. If the current device's uplink transmission segment has enough transmission time slots to meet the circuit rate corresponding to the leased line product to be activated, the port processor checks whether the current device has any idle ports. If the current device has idle ports, the port processor checks whether any of the idle ports contain ports of the type corresponding to the leased line product to be activated. If any of the idle ports contain ports of the type corresponding to the leased line product to be activated, the current device and its corresponding port that meet the above judgment conditions are selected as the device and port for leased line activation.

[0078] It should be noted that if all devices in the initial equipment room fail to meet the above judgment conditions, the fiber optic processor will jump to the first other equipment room in the equipment room where devices meet the above judgment conditions, and select the devices and corresponding ports in that other equipment room that meet the above judgment conditions as the devices and ports for the leased line.

[0079] In one optional embodiment, the step of selecting an effective path to all other equipment rooms via an optical fiber processor based on the optical cable topology information of the originating equipment room and the number of optical fiber cores specifically includes:

[0080] The fiber optic processor selects an effective path to all other equipment rooms based on the type and core utilization of the optical cables between the starting equipment room and all other equipment rooms, as well as the number of optical fiber cores in the optical cable topology map information of the starting equipment room.

[0081] Specifically, the effective path refers to a path between the starting equipment room and other equipment rooms where the type of optical cable used is a user optical cable and there are idle optical fibers that meet the number of optical fiber cores corresponding to the leased line product that needs to be opened; or, a path between the starting equipment room and other equipment rooms where the type of optical cable used is not a user optical cable but the fiber core utilization rate is less than or equal to a preset threshold and there are idle optical fibers that meet the number of optical fiber cores corresponding to the leased line product that needs to be opened.

[0082] In one specific embodiment, the leased line activation scheme output method is applied to the leased line activation scheme output system provided in this embodiment. The present invention completes the entire process through the following content, and each part is described in detail below:

[0083] I. Core Technical Content and Features

[0084] 1. System Architecture and Key Technology Overview

[0085] The dedicated line activation solution output system needs to process large-scale data, including but not limited to information on data centers, equipment, optical cables, and transmission systems. Therefore, the dedicated line activation solution output system needs to have the ability to efficiently and quickly process large amounts of data. At the same time, the business logic is complex and diverse, requiring the handling of multiple data types and information sources, and ensuring the correctness and integrity of the data during the processing.

[0086] The dedicated line activation solution output system needs to be designed to be efficient, scalable, and stable through optimized algorithms and data structures to cope with various challenges in high-concurrency scenarios. In a high-concurrency environment, a series of technical means are required to ensure the system's security and availability, such as load balancing, fault tolerance, data backup and recovery. High-concurrency design requires comprehensive optimization of system performance, including metrics such as response time, throughput, queries per second, and concurrent users.

[0087] The dedicated line deployment solution's output system needs a well-designed architecture and carefully selected algorithms to ensure stability when handling a large number of requests and guarantee timely and accurate responses to each request. High-concurrency design also requires attention to the full utilization and management of system resources. Reasonable resource allocation and scheduling strategies can maximize system performance and efficiency while avoiding resource waste and overload. Simultaneously, the system must ensure high availability and fault tolerance, enabling rapid recovery in the event of component failures. All security risks must be fully considered, and corresponding preventative measures must be taken, such as access control, encrypted communication, and protection against malicious attacks, to ensure user data security and privacy are protected.

[0088] Specifically, the dedicated line activation solution output system is developed using a Java distributed architecture. The system's business logic is broken down into different functions, ensuring each module has a degree of independence and reusability. As business volume grows, application and data services need to be separated to achieve more efficient data processing and improve application performance. Data storage and access are also separated. To enhance system availability and scalability, data storage and access are separated, allowing multiple applications to access the same database simultaneously without interfering with each other. Common business modules are extracted and deployed on distributed servers for application servers to call, avoiding redundant development and improving development efficiency and application performance. Reusable business functions are separated and deployed independently as distributed services, so new business functions only need to call these distributed services.

[0089] The dedicated line activation solution output system corresponding to this dedicated line activation solution output method includes the following modules:

[0090] Data Center Module: This module is responsible for processing data center network hierarchy attributes, data center type attributes, and other information.

[0091] Equipment Module: This module is responsible for processing information on various equipment in the computer room, including but not limited to equipment type, equipment manufacturer, and equipment model.

[0092] Fiber Optic Module: This module is responsible for processing fiber optic cable information, including but not limited to the facilities at both ends of the fiber optic cable, the fiber optic cable grade, and the usage status of the fiber optic cable.

[0093] Port Module: This module is responsible for processing information such as device boards, device port types, port usage, and device transmission segment usage overview.

[0094] Central Station Module: This module is responsible for processing information about the central station equipment room and optical distribution cabinet.

[0095] In terms of design patterns, Singleton, Proxy, Factory, and Chain of Responsibility patterns were selected. Around the automation sub-scenario, and using network orchestration capabilities as a means, the designed automation system architecture is as follows: Figure 2 As shown in the diagram, the system model is a chain-of-responsibility pattern. The processors include six units: a central office processor, a data center processor, a device processor, a port processor, a central fiber optic processor, and an optical distribution box processor. The optical distribution box processor has no business logic. Applicable products include: ordinary / LAN leased lines for the Internet, OTN intelligent network leased lines, Ethernet leased lines, government and enterprise premium networks, UTN leased lines, cloud networking, and client OTN device networking. Applicable scenarios include: MSTP, OTN / PEOTN, PON, IPRAN, and hybrid optical path + X scenarios. The main component of this chain-of-responsibility pattern is an abstract handler role, which defines an interface for handling requests and includes a successor connection. Concrete handler roles implement the abstract handler's processing methods, determining whether the request can be processed. If it can, it is processed; otherwise, the request is forwarded to its successor. These handler objects form a chain, and requests are forwarded along this chain. Each object has a consistent interface for handling requests and forwarding them to the next object.

[0096] The algorithm employs dynamic programming, divide-and-conquer, and quicksort. Quicksort is an efficient sorting algorithm with a time complexity of O(n log n). It uses a divide-and-conquer strategy, dividing the dataset into smaller subsets, recursively sorting these subsets, and finally merging them into a single ordered array. For the data to be searched, binary search is used. Binary search is also an efficient search algorithm with a time complexity of O(log n). It also uses a divide-and-conquer strategy, dividing the dataset into smaller subsets and recursively searching for the target value within these subsets. Finally, dynamic programming is used to decompose the problem into smaller subproblems and store the solutions to these subproblems for reuse when solving larger problems. This can optimize recursive algorithms and avoid repeatedly calculating the same subproblems. In summary, this system can use quicksort to sort data, binary search to search data, and dynamic programming to process data. These algorithms can be combined to achieve more efficient data processing.

[0098] 1. Data Preparation

[0099] 1-1. Select the type of dedicated line product to activate.

[0100] like Figure 3 As shown, the fully online workbench provides a function entry point. Select the leased line product to be activated, and enter the solution creation page for each service according to different leased lines. The service categories are: Ethernet leased line, Internet LAN leased line, Internet ordinary leased line, UTN leased line, cloud leased line, Ethernet leased line (cross-domain), MPLS_VPN (cross-domain), MPLS_VPN, cloud networking, government and enterprise premium network, OTN intelligent network leased line, low latency leased line, OTN / PEOTN master equipment networking, voice digital trunk, and SIP trunk.

[0101] 1-2. Input business information

[0102] 1-2-1. The input conditions for the business information scheme are shown in Table 1:

[0103] Table 1: Input Requirements for Business Information Schemes

[0104]

[0105] 1-2-2. Select the scenario, including Scenario 1 installation address, Scenario 2 main circuit, and Scenario 3 specified device, such as... Figure 4As shown, after selecting Scenario 1, the starting data center can be located using a fuzzy search by data center name. Select the required number of fiber cores, equipment interface type, and circuit speed for the dedicated line activation, and enter the order code and customer name.

[0106] 2. Data Analysis

[0107] 2-1. Rules for Occupying Computer Room

[0108] Specifically, first, query data centers whose network layer attribute value is "Metropolitan Area User Terminal" (this is the client data center). If no client data center can be found, then query data centers whose network layer attribute value is "Metropolitan Area Access Data Center," "POP Point," "Metropolitan Area Aggregation Data Center," "Metropolitan Area Core Data Center," or "Backbone Core Data Center," and whose data center type attribute value includes "Fixed Network Access." The service speeds opened in metropolitan area core data centers and backbone core data centers must be greater than or equal to 100 Mbps and less than or equal to 1 Gbps. The chain-of-responsibility model uses multiple functional modules as a chain.

[0109] When activating dedicated line services, the first step in developing a solution is to obtain the fiber optic cable topology information for the starting site. For example, a specific fiber optic cable topology diagram for the starting site would look like this: Figure 5 As shown, data center A and data center B are connected via fiber optic cable segment 1, and data center A and data center C are connected via fiber optic cable segment 2. The installation address, typically the data center, serves as the starting point. The data center module acts as the first processor, handling network layer attributes and data center type information. The processing result is used as the basis for determining the next processing module. The first processing module in the chain of responsibility initiates a request using a specific method, which sequentially passes the request to each processing module in the chain. If the data center resources meet the business requirements, the next processing module is the equipment processing module; otherwise, the fiber optic module is invoked.

Regarding the requirements for an effective path, if the optical cable containing the local fiber is a user cable, the idle fiber only needs to meet the input requirements; if it is not a user cable, the fiber core utilization rate must be less than or equal to 90% and the required number of fiber cores must be met.

[0112] 2-2-2, such as Figure 6 As shown, when there are multiple valid paths from the starting equipment room (i.e., the initial equipment room) to the ending equipment room (i.e., the termination equipment room), fiber core utilization and optical cable length are used as a weighted algorithm for a set of schemes. Fiber core utilization can be expressed as the ratio of the number of used fiber cores in the optical cable to the total number of fiber cores, while optical cable length represents the total length of the jumper path. One weighting algorithm is to combine fiber core utilization and optical cable length in a weighted manner to obtain a comprehensive weight value.

[0113] 2-2-3. Effective route routing needs to be refined to the fiber optic cable segment. That is, assuming that there are two fiber optic cable segments between BC in the route ABC, it needs to be decomposed into the routes A-B1-C1 and A-B2-C2.

[0114] Specifically, the optimal path for fiber optic patch cords can be generated using Dijkstra's algorithm, a shortest path algorithm in graph theory. This algorithm determines the shortest path between two given nodes, enabling the selection of the best path for fiber optic patch cords.

[0115] The system uses an algorithm to generate the optimal path for fiber optic patch cords. First, the entire fiber optic network needs to be modeled as a graph, where nodes represent connection points and edges represent the paths of the patch cords. Then, a shortest path algorithm can be used to calculate the shortest path between any two nodes, thereby determining the optimal path for the patch cords.

[0116] The code implementation is as follows:

[0117]

[0118]

[0119]

[0120] In a fiber optic module, one equipment room can typically be connected to n equipment rooms. Assuming each equipment room has an average of n fiber optic cables, the first patching generates n possible solutions, the second generates n^n solutions, and so on. Quick sort is then used to select a pivot element and divide the unsorted array into two subarrays: one subarray contains elements less than the pivot, and the other subarray contains elements greater than the pivot. These subarrays are then recursively sorted until the entire array is ordered (i.e., the set of solutions is ordered). Dynamic programming is then used to decompose the problem into a series of interrelated subproblems, and the solution to each subproblem is stored for reuse when needed. In this way, dynamic programming avoids repeatedly calculating the same subproblems, thus improving system efficiency.

[0123] 2-3. Equipment Occupancy Rules

[0124] If there are devices in the data center that meet the business requirements, sort the devices from largest to smallest according to their network element numbers, check whether the uplink transmission segment of the current device has enough transmission time slots to meet the circuit rate required by the customer, check whether the device has any idle ports, and whether the idle ports include the port type selected by the customer.

[0125] 3. Sample standardized output format of the solution:

[0126] Single-core or dual-core optical path [Client equipment room → Equipment room / optical cross-connect → Equipment room / optical cross-connect → Equipment room B] → Transmission equipment / interface type within equipment room B; for example: Figure 7 As shown, the single-core optical path is [A City Phase 1 (B1F) → B-line optical distribution box → C-line business hall] → 20513-D Life Plaza / FE electrical port. The electrical module in slot 7 needs to be replaced. A City Phase 1 and B-line optical distribution box, as well as B-line optical distribution box and C-line business hall, are connected by corresponding local fiber optic cables.

[0127] It should be noted that after the plan is created, a plan number is automatically generated. The plan number encoding rule is: SHLTZYFA-Y ...

[0128] like Figure 8 As shown, the automated process for dedicated line activation includes: business acceptance, solution creation, resource allocation and scheduling, data production, external line construction, completion reporting, and rental commencement and billing. Among these, the solution creation function must have the functions of solution query, solution modification, and solution deletion.

[0129] It is worth mentioning that this embodiment first reduces manual intervention and improves data accuracy by introducing an automated data input and verification mechanism. This improves the efficiency and accuracy of the activation scheme. Specifically, this embodiment has the following advantages:

[0130] 1. Automated Process: The key to automating the dedicated line activation solution lies in the degree of automation of the entire activation process. The process needs to cover business acceptance, resource verification, configuration plan formulation, and activation implementation, while minimizing manual intervention and improving activation efficiency.

[0131] 2. Equipment Compatibility: Leased line deployment solutions involve different types of equipment and network environments, therefore, equipment compatibility needs to be considered. The key is equipment selection to ensure that the equipment used meets the requirements of the deployment solution and avoids compatibility issues that could affect data transmission quality.

[0132] 3. Unified Management of the Network Management Platform (i.e., the Leased Line Activation Solution Output System): Automated output of leased line activation solutions also requires unified management of the network management platform. By building a unified network management platform, centralized management and monitoring of the leased line activation process can be achieved, improving management efficiency and reducing maintenance and management costs. Key aspects include the network management platform's architecture design, functional modules, and user interface, ensuring the platform is easy to use and maintain while meeting various leased line activation requirements.

[0133] The dedicated line activation scheme output method provided in this embodiment of the invention first receives the service information corresponding to the dedicated line product to be activated, selected and / or input by the user through a front-end page; then, based on the service information, multiple processors in the chain-of-responsibility mode sequentially verify and filter the data center, equipment, port, and fiber optic resources, starting from the initial data center for dedicated line activation, and output a dedicated line activation scheme including the path and / or equipment and port information for dedicated line activation. The chain-of-responsibility mode connects multiple processors into a chain, so that the request for dedicated line activation is processed layer by layer in a preset order. The multiple processors include a data center processor, an equipment processor, a port processor, and a fiber optic processor. This invention utilizes a chain-of-responsibility model for data center processors, equipment processors, port processors, and fiber optic processors. Based on the service information corresponding to the leased line product selected and / or input by the user through a front-end page, it verifies and filters the data center, equipment, ports, and fiber optic resources for leased line activation, and outputs the corresponding leased line activation plan. This replaces the manual work of configuring and outputting leased line activation plans, avoids errors that may occur during manual configuration, significantly improves activation efficiency, and solves the problem that existing leased line activation plans rely on manual configuration, resulting in low activation efficiency and a high risk of errors.
