[0026] The technical solutions of the present application will be described clearly and completely below in conjunction with embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] Taking a game-dedicated network as an example, the current game platform has various types of games, from role-playing to shooting games, to meet the needs of various players. However, for game players, problems such as game lag and slow update download have been a problem that needs to be solved urgently. Operators need to provide a stable connection and high-speed download service.

[0028] The game-dedicated network provides exclusive channel bandwidth guarantee for users to download and update games, and supports acceleration of multiple games, that is, if a game-dedicated broadband is used, players will have a good experience in speed whether they download games or play specific games. The game service is on an independent channel, and the edge node is accessed through a dedicated network, so the path is shorter, resulting in lower latency and further improving user experience.

[0029] How to ensure that the game network can run in high quality, both to improve the quality of the game-dedicated network, and to reduce the difficulty of game-dedicated network construction, the current various performance detection technologies monitor, measure, and collect network performance data, analyze, evaluate, control, and adjust the network running state to provide long-term stable and reliable network services, which is the basis of network operation.

[0030] The existing detection technologies have the following several kinds, and each has advantages and disadvantages, and the application scenarios are also different:

[0031] TWAMP (Two-Way Active Measurement Protocol, Two-Way Active Measurement Protocol) is mainly used for end-to-end IP (Internet Protocol) service flow level detection, but since it is a detection message constructed by measurement, the detection accuracy is low, and it has no hop-by-hop detection capability.

[0032] RFC 2544(Reqest for comments), Y.1564 are usually used to measure the SLA capability of the device, network (Service Level Agreement ensures high reliability and continuity of network connection.), there is a certain gap with the actual business flow SLA.

[0033] Y.1731(CFM) is only used for L2 traffic (refers to the second level of business process in the enterprise), and cannot be applied to the detection of three-layer traffic;

[0034] MPLS-TP OAM(Multi-Protocol Label Switching Transport Profile, Multi-Protocol Label Switching Transport Profile), RFC 6374 only supports MPLS pipe level testing, and does not support out-of-order, load sharing, point-to-multipoint scenarios such as link aggregation group LAG, equal cost multipath ECMP, dual homing, etc., and also does not support hop-by-hop measurement.

[0035] In-situ OAM, INT, etc. are currently popular passive measurement technologies, the main principle of which is to add OAM detection headers in the original data packet, collect data according to the detection header in the business forwarding path, and calculate the detection results through the centralized processing unit. This kind of flow detection technology has the advantages of real-time, high precision, rich detection performance, etc., but the measurement data volume is huge, and the influence on the business itself is also large, and at present more consideration is given to the use in data center scenarios.

[0036] For data networks with large data volume and high real-time requirements, operators provide dedicated networks with higher requirements in terms of bandwidth, delay, connection flexibility, etc. From the perspective of network operation and maintenance, the performance detection technology mainly has the following demands:

[0037] (1) Network daily performance monitoring: Provide real-time SLA(Service Level Agreement) monitoring based on IP traffic level, master the real-time health status of the network, and meet the daily operation and maintenance monitoring requirements.

[0038] (2) Network fast troubleshooting and demarcation capability: For external faults of the bearer network, it is necessary to provide fast and accurate measurement means to prove innocence. For internal faults of the bearer network, it is necessary to provide fast troubleshooting and demarcation means to quickly locate the fault point and isolate and repair the fault.

[0039] (3) Network automation and intelligent operation and maintenance: Network functions are becoming more flexible, and network maintenance is becoming more complex, which requires the transformation of network operation and maintenance to automation and intelligence. Relying on real-time performance detection data of the whole network, build a big data intelligent operation and maintenance system, and intervene, adjust and optimize the possible risks of the network in advance to realize automatic and intelligent operation and maintenance.

[0040] Based on the operation and maintenance demand of the delay-sensitive data network and the private network, and in combination with the advantages and disadvantages of the existing performance detection technology, an embodiment of the present application provides a network performance monitoring method, device and system for realizing intelligent operation and maintenance. The network performance monitoring is performed in a manner of in-band performance monitoring, end-to-end or hop-by-hop, so as to guarantee the stable operation of the network and improve the network performance. In order to facilitate the understanding of the embodiment, first, a network performance monitoring method for realizing intelligent operation and maintenance disclosed by the embodiment is introduced in detail.

[0041] Figure 1 A flowchart of the network performance monitoring method for realizing intelligent operation and maintenance provided by the embodiment of the present application. The method is applied to an in-band performance monitoring system, the in-band performance monitoring system is connected with a plurality of devices, including core layer devices and access layer devices (i.e. edge devices); the plurality of devices are configured with a target network; the target network can be a game private network or other network to be monitored; the method specifically includes the following steps:

[0042] Step S102, according to the in-band performance monitoring configuration information, a message monitoring instruction carrying corresponding instance configuration information is sent to each device, so that each device generates a corresponding message monitoring instance according to the corresponding instance configuration information, and performs service message monitoring based on the message monitoring instance;

[0043] Among them, the in-band performance monitoring configuration information includes: instance configuration information for message monitoring between devices based on the flow-based measurement principle and end-to-end or hop-by-hop; through the in-band performance monitoring configuration information, it can be determined which two devices perform end-to-end message monitoring, which devices perform hop-by-hop monitoring, and the corresponding instance configuration information.

[0044] Through the above instance configuration information, the device can automatically generate the corresponding message monitoring instance, thereby realizing service message monitoring to determine the packet loss rate, delay size, out-of-order detection result, jitter condition, real-time traffic and other monitoring results of the link between devices.

[0045] In the implementation process of the above step of sending a message monitoring instruction carrying corresponding instance configuration information to each device, the in-band monitoring system uses the Reflection dynamic call of JAVA to realize the plug-in of the netconf (i.e. the message monitoring instruction carrying the corresponding instance configuration information) of the newly added manufacturer device, and then uses the variable substitution characteristics of the template to realize the dynamic substitution of the message parameters. The management personnel can modify the static message template to adapt to different types of devices. Thus, the custom netconf message template management function is realized, and the configuration of the newly added manufacturer can be configured.

[0046] Step S104, receiving the message monitoring result returned by each device through network telemetry technology to determine the network performance monitoring result corresponding to the target network.

[0047] After each device performs the monitoring of the service message, the message monitoring result is automatically returned to the in-band performance monitoring system. The in-band performance monitoring system can quickly perceive network faults, accurately delimit and troubleshoot based on the message monitoring result returned by each device.

[0048] The network performance monitoring method for intelligent operation and maintenance provided by the embodiments of the present application is a service flow level-based, real-time, high-precision and accurate performance monitoring mechanism for feeding back actual traffic performance of customers, which combines IFIT (in-situ Flow Information Telemetry) technology, directly measures service messages to obtain real packet loss rate, delay and other performance indicators of a game special network, has high monitoring precision, is easy to deploy and has future expansion capability. The method provides IP service flow level end-to-end and hop-by-hop SLA (mainly including packet loss rate, delay, jitter and real-time traffic) measurement capability, can quickly perceive network faults, accurately delimit and troubleshoot, is an important means for network operation and maintenance of a delay-sensitive network such as a game special network, provides full-network delay visualization, delay anomaly monitoring and delay routing for delay-sensitive services, realizes intelligent operation and maintenance of the network and improves user experience.

[0049] The embodiments of the present application also provide a network performance monitoring method for intelligent operation and maintenance, which is implemented on the basis of the above-mentioned embodiment. The configuration process of configuration information and the overall architecture are mainly described in this embodiment.

[0050] The above-mentioned step of receiving the message monitoring result returned by each device through network telemetry technology includes: caching the real-time received message monitoring result to a message queue; and real-time consuming the message in the message queue by a flink data processing task and backfilling the network element resource data in redis to record the message monitoring result corresponding to each device respectively.

[0051] In this embodiment, the in-band performance monitoring data (i.e. the message monitoring result uploaded by each device) is integrated. Since the data volume is too large and real-time performance and accuracy are required to be relatively high, a flink is used as a data processing engine in this embodiment, and the following is used:

[0052] The whole processing architecture design of Telemetry-> Probe-> Kafka-> Flink-> mysql is reasonable and can realize real-time network log analysis.

[0053] Further, the method further comprises: visualizing the network performance monitoring result, and performing path optimization and / or network fault risk prediction based on the network performance monitoring result and the intelligent algorithm, to realize intelligent operation and maintenance.

[0054] Referring to Figure 2 As shown in the figure, the overall network performance monitoring process is as follows:

[0055] 1) The user performs monitoring strategy configuration, that is, the configuration of the aforementioned in-band performance monitoring configuration information, as shown in step 1 in the figure;

[0056] 2) The in-band performance monitoring system (configured with big data and intelligent algorithms) converts the monitoring strategy configured by the user into a command line and issues it to the device through NETCONF, that is, issues the corresponding message monitoring instruction carrying instance configuration information to each device (such as PE1, P1, and PE2), that is, the Netconf configuration issuance shown in step 2 in the figure;

[0057] 3) Each device generates end-to-end or hop-by-hop message monitoring instances according to the Netconf configuration information and performs service message monitoring, and returns statistical data (message monitoring result) to the in-band performance monitoring system through the Telemetry network telemetry technology, as shown in step 3 in the figure;

[0058] 4) The in-band performance monitoring system processes the message monitoring result uploaded by each device based on big data, and visualizes the network performance monitoring result of the target network, and further realizes risk prediction and path optimization based on the intelligent algorithm, as shown in step 4 in the figure, which optimizes the path according to the monitoring result.

[0059] In order to meet the higher requirements of users on service quality, by deploying in-band performance monitoring in the game special network, the packet loss rate and delay size of the link between PE to PE can be monitored in real time, so as to make timely adjustment when the service quality of the user decreases. The bidirectional flow monitoring function is supported on the device, and the reverse flow instance is automatically generated through the forward flow created on one end device. In the actual network, there are more access layer devices and fewer core layer devices. If bidirectional monitoring flow is created on core layer device, the configuration and maintenance workload can be greatly reduced.

[0060] Further, the configuration process of the aforementioned in-band performance monitoring configuration information is as follows: the in-band performance monitoring system provides an in-band performance monitoring configuration page; in response to a configuration operation on specified information in the in-band performance monitoring configuration page, in-band performance monitoring configuration information is generated; the specified information includes: target network identifier, flow direction, source network element and sink network element, detection mode; the flow direction includes bidirectional or unidirectional; the detection mode includes end-to-end mode or hop-by-hop mode.

[0061] Further, the specified information further includes at least one of the following: measurement period, address type, flow information, and out-of-order measurement.

[0062] Further, the response to the configuration operation of the specified information in the in-band performance monitoring configuration page generates the in-band performance monitoring configuration information, including: the in-band performance monitoring configuration page includes: a network element selection page and a monitoring configuration page; the monitoring configuration page is generated in response to the configuration operation of the target network name, flow direction, source network element and destination network element in the network element selection page; and the configuration information of the inter-device end-to-end or hop-by-hop network performance monitoring instance is generated in response to the configuration operation of the flow information, detection mode, measurement period and address type in the monitoring configuration page.

[0063] In specific implementation, refer to the network architecture diagram shown in Figure 3 , wherein the P device represents a core layer device, and the PE1 device and the PE2 device represent access layer devices, i.e., edge devices.

[0064] 1. Configure a game-specific network, i.e., the target network, on the PE device and the P device.

[0065] 2. Configure the 1588v2 basic function to realize clock synchronization between devices.

[0066] 3. Configure the packet loss and delay statistics function of the link between the PE devices to realize periodic statistics of the packet loss rate and transmission delay of the bearing network.

[0067] 4. Configure the device to upload the monitoring data to the in-band performance monitoring system through Telemetry.

[0068] 5. The in-band performance monitoring system collects and analyzes the in-band performance monitoring raw data in real time, and caches them in the message queue Kafka.

[0069] 6. The flink data processing task consumes the raw data in real time, and backfills the network element resource data in the redis.

[0070] 7. The in-band performance monitoring system presents the network performance monitoring result.

[0071] When it is necessary to monitor the special network, it is necessary to create a corresponding monitoring instance in the in-band performance monitoring system. As shown in Figure 4 , first, find the game-specific network, select “one-way” or “two-way” (two-way deployment is recommended, and there are two business flows in the positive and reverse directions), and display the end-to-end devices involved in the network in the “source network element” and “destination network element” lists.

[0072] As shown in Figure 5 , the monitoring configuration page is displayed, and the user can configure the monitoring parameters in the page.As shown, in this embodiment, IPv4 flow or IPv6 flow can be monitored, dual stack monitoring is supported, E2E monitoring or hop-by-hop monitoring can be directly issued, and E2E monitoring is recommended to be issued.

[0073] As shown, the "Status" column of the newly created instance shows "Success", indicating that the deployment is completed. Figure 6 As shown, the "Status" column of the newly created instance shows "Success", indicating that the deployment is completed.

[0074] Compared with traditional monitoring technologies, the in-band performance monitoring system is based on flow measurement principle, provides higher precision SLA measurement, supports various flexible networking scenarios such as dual homing, ECMP / LAG, etc., and has the advantages of iOAM / INT flow monitoring technology, provides better scalability, uses dyeing mechanism to reduce complexity, introduces less overhead compared with iOAM / INT, and is more suitable for application scenarios of bearer networks. The in-band performance monitoring provides IP service level end-to-end and hop-by-hop measurement, meets daily operation and maintenance monitoring and fault fast localization requirements, and is an important operation and maintenance means of game special network.

[0075] The network performance monitoring method provided by the embodiments of the present application has the following advantages:

[0076] 1. The in-band performance monitoring data is reported to the system through telemetry, the system realizes real-time collection and analysis of data, and can perform multi-instance collection, and independently realizes real-time collection and analysis of telemetry reporting data of measurement results of multi-vendor devices, and realizes high availability and load balancing scheme of collection instances.

[0077] 2. The scheme integrates in-band performance monitoring data. Since the data volume is too large and real-time and accuracy are required, the scheme takes flink as a data processing engine, and the whole processing architecture design of Telemetry-> Probe-> Kafka-> Flink-> mysql is reasonable, and can realize real-time network log analysis. Since the scheme needs to associate a large amount of real-time data to ensure the accuracy of the program, how to ensure the reliability and speed of association in the process of ensuring real-time processing of large data volume becomes very important.

[0078] 3. The system function architecture, design and development are independently researched and developed, and realize visual configuration and issuing of game special network monitoring instance tasks.

[0079] 4. The self-defined netconf message template management function is used to realize the configurable configuration issuing message of the newly added vendor. The system uses the Reflection of JAVA to dynamically call the issuing implementation class, realizes the plug-in of the netconf of the newly added vendor device, then uses the variable replacement characteristics of the template to realize the dynamic replacement of the message parameters, and the management personnel can modify the static message template to adapt to different types of devices. The management information becomes the database that can be understood by the computer, improves the processing capability of the computer on the network management data, and thus improves the network management capability.

[0080] Based on the above method embodiment, the embodiment of the application further provides another network performance monitoring method for realizing intelligent operation and maintenance. The method is applied to a device, the device is connected with an in-band performance monitoring system, and the device is configured with a target network. As shown in Figure 7 The method comprises the following steps:

[0081] In step S702, a message monitoring instruction carrying corresponding instance configuration information is received, which is sent by the in-band performance monitoring system according to in-band performance monitoring configuration information. The in-band performance monitoring configuration information comprises instance configuration information for message monitoring between devices based on the end-to-end or hop-by-hop principle of stream-based measurement.

[0082] In step S704, a message monitoring instance is generated according to the instance configuration information, and service message monitoring is performed based on the message monitoring instance.

[0083] In step S706, the network telemetry technology is used to return the message monitoring result to the in-band performance monitoring system, so that the in-band performance monitoring system determines the network performance monitoring result of the target network.
