Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a BRAS equipment resource monitoring and service scheduling method, a BRAS equipment resource monitoring and service scheduling system, an electronic device and a computer-readable storage medium. Background Art

[0002] With the popularization of gigabit broadband products, the scale of broadband services is getting larger and larger. As a result, BRAS (Broadband Remote Access Server) equipment resources are prone to overload, resulting in frequent slow Internet access,

[0003] Complaints about network instability, interruption, etc. that affect users' Internet access experience. When handling these complaints, it is often necessary to manually troubleshoot the cause and manually switch services. The current OLT (optical line terminal) is dual-connected to two BRASs, and the service load is shared between the two BRASs. When one of the upstream relays of the OLT fails, the service load will be unilaterally pressed on one BRAS, which may cause BRAS resource overload (such as IP address pool overflow, BRAS upstream relay overload, etc.), thereby affecting user use. When equipment resource overload occurs, operation and maintenance personnel solve it by manually adjusting the service load. Although the current technical solution can realize monitoring of BRAS equipment and switch traffic when a BRAS session resource pool is in short supply; for example, patent CN106936729A "A terminal equipment access control method, system and broadband access network system" proposes a terminal equipment access control method, system and broadband access network, which can realize that when the BRAS resources in the broadband network are overloaded, the service is automatically switched to the BRAS with sufficient resources, thereby ensuring the normal use of Internet services. However, these solutions generally still have the following problems:

[0004] 1. Inefficiency: Only a technology for monitoring broadband services is provided, which can only detect broadband service problems and still requires operation and maintenance personnel to spend time and energy to manually switch service loads;

[0005] 2. Low accuracy: There are multiple indicator dimensions for evaluating BRAS device resource overload. The current solution only mentions monitoring device uplink traffic, license utilization, or the number of online broadband users. It cannot accurately cover the common possible scenarios of resource overload of device network elements;

[0006] 3. Poor flexibility: When the service load needs to be automatically switched to other equipment network elements, the current solution can only adjust the global broadband service of the BRAS, and cannot make on-demand adjustments based on the service of a single OLT port. Summary of the invention

[0007] In order to at least solve the problems of low accuracy in evaluating BRAS equipment resource overload, low efficiency and poor flexibility in service adjustment in the prior art, the present invention provides a BRAS equipment resource monitoring and service scheduling method, a BRAS equipment resource monitoring and service scheduling system, an electronic device and a computer-readable storage medium, which can accurately analyze and monitor common scenarios of equipment resource overload, automatically switch and schedule the service load to equipment with normal resources, and switch and adjust as needed, with high efficiency and strong flexibility.

[0060] The purpose of the embodiments of the present disclosure is to solve the problem of network failure caused by overload of equipment resources in broadband networks, to achieve automation of emergency fault handling, to realize intelligent network operation and maintenance, and to save time for manual troubleshooting.

[0061] To achieve this goal, the disclosed embodiment connects the data of the smart F5G (The 5th generation Fixed networks, the fifth generation fixed network) network management and digital operation platform; and directly collects the data of BRAS equipment. At the same time, a database is built, a new MySQL database is created, data is collected from existing systems to generate the topological relationship between the BRAS and OLT of the entire network, and various indicator data of BRAS equipment resources are collected from the equipment network elements. To ensure the real-time nature of the data, collection and processing are performed at regular intervals. The collected data table is used to analyze and judge the performance of equipment resources, and the BRAS resource table is constructed based on the equipment managed by the smart F5G network management, combined with the information collected by the digital platform and the equipment network elements. The resource table contains the topological relationship between the BRAS and OLT of the entire network, and the resource usage of each BRAS device; the generated BRAS resource table is stored in the database. It is updated according to the preset period, and the preset period sent can be consistent with the collection interval or inconsistent. When new data is collected, the BRAS resource table is updated.

[0062] Using the BRAS resource table as the data base, the resource usage of the current BRAS equipment network elements is monitored through the BRAS resource table, and BRAS equipment network elements with resource overload are analyzed in time, and the service load is automatically switched to other BRAS equipment with normal resources through the platform system robot; when making overload judgments, judgments can be made based on data features collected from multiple data sources. When a data feature is abnormal, the equipment process can be judged, and abnormal judgments in multiple indicator dimensions can be realized, such as the equipment uplink CR port traffic and downlink OLT port traffic obtained by the network management system; the number of online broadband users, license utilization, IP address pool utilization, CGN board traffic utilization, etc. obtained by directly collecting BRAS equipment. Accurately analyze and monitor common scenarios of equipment resource overload;

[0063] After detecting that the BRAS device network element resources are overloaded, the broadband services of the OLT ports are switched one by one according to the topological relationship between the devices, and their service loads are automatically switched to other BRAS devices with normal resources until the overloaded device network element returns to normal indicators. On-demand switching adjustment is achieved, and the global broadband services of a single BRAS device will not be affected at one time.

[0064] The disclosed embodiment connects the data of the smart network management and digital operation platform, and directly collects the data of BRAS equipment, analyzes and integrates it to form an equipment resource table; collects and analyzes the resource usage of BRAS equipment from multiple indicator dimensions, accurately analyzes and monitors common scenarios of equipment resource overload; when it is detected that the equipment network element resources are overloaded, the platform system sends instructions to the equipment with resource overload, and the service load is automatically switched and dispatched to the equipment with normal resources without manual intervention by operation and maintenance personnel; and by collecting the topological relationship of BRAS and OLT in the entire network to generate the association relationship between devices, when the equipment network element resources are overloaded and affect the user's Internet access, the platform system automatically switches the broadband service according to the topological relationship between the devices, which is convenient and flexible, and can realize on-demand switching adjustment, and will not affect the global broadband service of a single BRAS device at one time. It has the advantages of high accuracy, high efficiency and flexible adjustment

[0065] Furthermore,

[0066] The topological relationship between the broadband network devices and resource utilization information include:

[0067] The topological relationship between BRAS devices and OLT devices in the entire network, the uplink port information and traffic utilization rate of BRAS devices, and the downlink OLT port information and traffic utilization rate;

[0068] The resource usage information of the BRAS device includes:

[0069] Online broadband user data of BRAS equipment, IP address pool usage data, available addresses, and CGN board traffic usage data. The IP address pool includes CGN public network address pool, broadband private network address pool, iptv private network address pool, broadband public network address pool, and rms optical modem registration address pool.

[0070] Collect data from smart F5G network management, BRAS equipment, and digital operation platform. Specific data include:

[0071] Smart F5G network management: BRAS equipment manufacturer and version model, upstream CR port and traffic utilization, downstream OLT port and traffic utilization;

[0072] Digital operation platform: topological correspondence between BRAS and OLT in the whole network;

[0073] BRAS equipment: number of online broadband users, CGN public network address pool usage data, broadband private network address pool usage data, IPTV private network address pool usage data, broadband public network address pool usage data, RMS optical modem registered address pool usage data, number of available addresses, CGN board traffic usage and other data.

[0074] To ensure the real-time nature of the data, the above data are collected and updated once at a certain interval, and the BRAS resource table is updated.

[0075] Furthermore,

[0076] The preset period is 3 minutes, 5 minutes or 10 minutes;

[0077] The method further comprises:

[0078] The data in each network management system, operation platform system and BRAS equipment are collected and updated at intervals of the preset period, and updated to the BRAS resource table according to the preset period.

[0079] In order to obtain BRAS devices with resource overload more quickly, all data is collected through a preset period and updated to the BRAS resource table. This allows the system to schedule service switching for devices with resource overload as soon as possible, preventing the occurrence of faults such as slow user network or inability to access the Internet due to overloaded device resources, shortening the duration of fault impact and reducing customer complaints.

[0080] The preset period is set according to actual conditions and can be set to 3 minutes, 5 minutes or 10 minutes; 5 minutes is preferred.

[0081] Further, monitoring the resource usage of the current BRAS device through the BRAS resource table to find out the BRAS device with overloaded resources includes:

[0082] Monitor and analyze the various feature items of each BRAS device data in the BRAS resource table, including the peak utilization rate of the device's upstream CR device port traffic, the peak utilization rate of all downstream OLT port traffic of the BRAS, the IP address pool utilization rate, the number of available IPs, the license resource utilization rate, and the CGN board traffic utilization rate;

[0083] It is determined whether each characteristic item of the BRAS device exceeds its corresponding preset threshold. If any characteristic item exceeds, it is considered that the device resources are overloaded.

[0084] According to each characteristic item of each BRAS device data in the BRAS resource table, it is judged whether the BRAS device is overloaded. The preset threshold corresponding to each characteristic item can be set according to the actual situation. The following is an implementation scenario of judging whether the device is overloaded by each characteristic item.

[0085] ① Uplink CR port monitoring and analysis: The peak utilization rate R of the equipment uplink CR device port traffic during the cycle is collected every 5 minutes. When R>75%, it means that the equipment uplink traffic load is close to saturation, and it is judged as equipment resource overload, otherwise it is judged as normal.

[0086] ② Monitoring and analysis of downstream OLT ports: The peak traffic utilization rate T of all downstream OLT ports of the BRAS during the period is collected every 5 minutes. When T>75%, it means that the downstream traffic load of the equipment is close to saturation, and it is judged as equipment resource overload, otherwise it is judged as normal.

[0087] ③IP address pool monitoring and analysis: The usage of the device network element IP address pool during the period is collected every 5 minutes, including the CGN public network address pool utilization rate, broadband private network address pool utilization rate, IPTV private network address pool utilization rate, broadband public network address pool utilization rate, and RMS optical modem registered address pool utilization rate. If one of the monitoring items is >85%, it means that the IP address pool is close to overflowing and it is judged as device resource overload. Otherwise, it is judged as normal.

[0088] ④ Monitoring and analysis of the number of available IP addresses: Data is collected every 5 minutes. If the number of available IP addresses of the device is less than 2000, it is considered that the device resources are overloaded, otherwise it is considered normal.

[0089] ⑤License resource monitoring and analysis: The license resource usage rate S of the device network element during the collection period is collected every 5 minutes. When S>50%, it is judged that the device resource is overloaded, otherwise it is judged to be normal.

[0090] ⑥CGN board traffic monitoring and analysis: The CGN board traffic usage rate C of the equipment network element during the collection period is collected every 5 minutes. When C>50%, it means that the 1+1 redundant backup function of the service board fails and it is judged that the equipment resources are overloaded. Otherwise, it is judged to be normal.

[0091] When a device resource is judged to be overloaded due to one of the items, the device can be determined as a BRAS device with overloaded resources, and the business load can be automatically switched to other BRAS devices with normal resources through the robot of the platform system.

[0092] By collecting and analyzing the resource usage of BRAS equipment from multiple indicator dimensions such as device uplink traffic, number of online broadband users, license utilization, IP address pool utilization (including CGN public network, broadband private network, IPTV private network, broadband public network, RMS), and CGN board traffic utilization, we can accurately analyze and monitor common scenarios of device resource overload; make resource overload judgment more comprehensive and accurate; and make business adjustments as soon as possible to prevent complaints such as slow Internet access, network instability, and interruptions that affect users' Internet access perception.

[0093] Furthermore, the automatic switching of the service load to other BRAS devices with normal resources according to the topological relationship between the devices includes:

[0094] For BRAS devices that are judged to be resource overloaded, the topological relationship between devices is used to automatically find the BRAS-n device with normal resource status on the other side of the OLT-n device connected to the device;

[0095] Execute the service dispatch instruction to switch the service load of the OLT-n under the overloaded BRAS device to the normal BRAS-n device;

[0096] After a preset interval, determine whether the overloaded BRAS device is still overloaded. If so, repeat the above steps to continue looking for the corresponding BRAS device with normal resources to switch services until the resource status of the overloaded BRAS device in the resource table returns to normal.

[0097] When performing business switching scheduling, the platform system sends instructions to the device with overloaded resources, and the business load is automatically switched to the device with normal resources without manual intervention by operation and maintenance personnel;

[0098] When performing service switching scheduling: the platform system retrieves the analysis results corresponding to the processed BRAS resource table in the database. If it is judged that the resources are overloaded, the platform robot executes the instructions sent to the device and automatically switches the scheduling service to the BRAS device with normal resources. The process of system switching service is:

[0099] ① When a device network element in the resource table is judged to be resource overloaded, it is assumed to be BRAS-1. Through the topological relationship between devices, the first OLT-1 under the device is automatically discovered, and the other side BRAS-2 connected to the OLT-1 is found. When BRAS-2 is also judged to be resource overloaded, the platform robot will not execute the switching scheduling instruction for the service load of the OLT-1. Continue to search for the second OLT-2 under the device, and perform the above repeated steps until the resource status of the BRAS-n device on the other side connected to OLT-n is found to be normal.

[0100] ② When the OLT-n under BRAS-1 is found, the other BRAS-n connected to the OLT-n is found. When the BRAS-n is judged to have normal resources, the platform robot executes the service scheduling instruction and switches the service load of the OLT-n under the BRAS-1; after an interval of 5 minutes, if the BRAS-1 in the resource table is still judged to be overloaded, it will continue to find the OLT under the device and re-execute the above steps until the resource status of the BRAS-1 in the resource table is normal.

[0101] By collecting the topological relationship of BRAS and OLT in the whole network and generating the association relationship between devices, when the overload of device network element resources affects the user's Internet access service, the platform system switches the broadband service of the OLT port one by one according to the topological relationship between devices until the overloaded device network element returns to normal indicators. The service load can be automatically switched to the device with normal resources without manual intervention by operation and maintenance personnel; and on-demand switching adjustment is realized, which will not affect the global broadband service of a single BRAS device at one time.

[0102] The second embodiment of the present disclosure also provides a BRAS equipment resource monitoring and service scheduling method, which is implemented by constructing a BRAS equipment resource monitoring and service intelligent scheduling system in a broadband network. The system includes a data acquisition module, a data processing module, a data storage module and a service switching scheduling module.

[0103] Build a database. Create a new MySQL database, collect data from existing systems to generate the topological relationship between BRAS and OLT in the entire network, and collect various indicator data of BRAS equipment resources from equipment network elements. To ensure the real-time nature of data, collect and process it every 5 minutes. The collected data table is analyzed and judged for equipment resource performance in the processing module, and a BRAS resource table is generated for storage.

[0104] Figure 2 This is a functional structure and method implementation process diagram of the BRAS resource monitoring and service scheduling system in the broadband network, including:

[0105] 1. Data collection: The data collection module collects data from the smart F5G network management, BRAS equipment, and digital operation platform. The specific data includes:

[0106] ① Smart F5G network management: BRAS equipment manufacturer and version model, upstream CR port and traffic utilization, downstream OLT port and traffic utilization;

[0107] ②BRAS equipment: number of online broadband users, CGN public network address pool usage data, broadband private network address pool usage data, IPTV private network address pool usage data, broadband public network address pool usage data, RMS optical modem registered address pool usage data, number of available addresses, CGN board traffic usage and other data;

[0108] ③Digital operation platform: topological correspondence between BRAS and OLT in the whole network;

[0109] To ensure the real-time nature of the data, the above data are collected and updated every 5 minutes and input into the data processing module to update the BRAS resource table.

[0110] 2. Data processing: Based on the equipment managed by the smart F5G network management, the BRAS resource table is constructed by combining the information collected by the digital platform and the equipment network elements. The resource table contains the topological relationship between the BRAS and OLT in the entire network and the resource usage of each BRAS device. The data collection module polls and collects data every 5 minutes, and the data processing module uniformly processes and updates it. The following is the processing and analysis process.

[0111] ① Uplink CR port monitoring and analysis: The peak utilization rate R of the equipment uplink CR device port traffic during the cycle is collected every 5 minutes. When R>75%, it means that the equipment uplink traffic load is close to saturation, and it is judged as equipment resource overload, otherwise it is judged as normal.

[0112] ② Monitoring and analysis of downstream OLT ports: The peak traffic utilization rate T of all downstream OLT ports of the BRAS during the period is collected every 5 minutes. When T>75%, it means that the downstream traffic load of the equipment is close to saturation, and it is judged as equipment resource overload, otherwise it is judged as normal.

[0113] ③IP address pool monitoring and analysis: The usage of the device network element IP address pool during the period is collected every 5 minutes, including the CGN public network address pool utilization rate, broadband private network address pool utilization rate, IPTV private network address pool utilization rate, broadband public network address pool utilization rate, and RMS optical modem registered address pool utilization rate. If one of the monitoring items is >85%, it means that the IP address pool is close to overflowing and it is judged as device resource overload. Otherwise, it is judged as normal.

[0114] ④ Monitoring and analysis of the number of available IP addresses: Data is collected every 5 minutes. If the number of available IP addresses of the device is less than 2000, it is considered that the device resources are overloaded, otherwise it is considered normal.

[0115] ⑤License resource monitoring and analysis: The license resource usage rate S of the device network element during the collection period is collected every 5 minutes. When S>50%, it is judged that the device resource is overloaded, otherwise it is judged to be normal.

[0116] ⑥CGN board traffic monitoring and analysis: The CGN board traffic usage rate C of the equipment network element during the collection period is collected every 5 minutes. When C>50%, it means that the 1+1 redundant backup function of the service board fails and it is judged that the equipment resources are overloaded. Otherwise, it is judged to be normal.

[0117] 3. Data storage: The BRAS resource table is stored in the database and updated every 5 minutes.

[0118] 4. Service switching scheduling: The platform system retrieves the analysis results corresponding to the processed BRAS resource table in the database. If it is judged that the resources are overloaded, the platform robot will execute the instructions sent to the device and automatically switch the scheduling service to the BRAS device with normal resources. The process of system switching service is:

[0119] ① When a device network element in the resource table is judged to be resource overloaded, it is assumed to be BRAS-1. Through the topological relationship between devices, the first OLT-1 under the device is automatically discovered, and the other side BRAS-2 connected to the OLT-1 is found. When BRAS-2 is also judged to be resource overloaded, the platform robot will not execute the switching scheduling instruction for the service load of the OLT-1. Continue to search for the second OLT-2 under the device, and perform the above repeated steps until the resource status of the BRAS-n device on the other side connected to OLT-n is found to be normal.

[0120] ② When the OLT-n under BRAS-1 is found, the other BRAS-n connected to the OLT-n is found. When the BRAS-n is judged to have normal resources, the platform robot executes the service scheduling instruction and switches the service load of the OLT-n under the BRAS-1; after an interval of 5 minutes, if the BRAS-1 in the resource table is still judged to be overloaded, it will continue to find the OLT under the device and repeat the above steps until the resource status of the BRAS-1 in the resource table is normal.

[0121] The embodiments of the present disclosure can solve the problems existing in the existing methods, and have the following advantages:

[0122] 1. High efficiency: This embodiment collects the usage of BRAS equipment resources in the entire network. When it detects that the equipment network element resources are overloaded, the platform system sends instructions to the equipment with overloaded resources, and the service load is automatically switched to the equipment with normal resources without manual intervention by operation and maintenance personnel.

[0123] 2. High accuracy: The resource usage of BRAS equipment is collected and analyzed from multiple indicator dimensions such as equipment uplink traffic, number of online broadband users, license utilization, IP address pool utilization (including CGN public network, broadband private network, IPTV private network, broadband public network, RMS), and CGN board traffic utilization, so as to accurately analyze and monitor common scenarios of equipment resource overload;

[0124] 3. High flexibility: The platform system generates the relationship between devices by collecting the topological relationship of BRAS and OLT in the whole network. When the overload of device network element resources affects the user's Internet access service, the platform system switches the broadband service of the OLT port one by one according to the topological relationship between the devices until the overloaded device network element returns to normal indicators. This method realizes on-demand switching adjustment and will not affect the global broadband service of a single BRAS device at one time.
