With the development of communication networks, various emerging networks are widely used. For example, the 5th generation mobile communication technology (5G) network has the characteristics of large bandwidth, low latency, and the ability to connect people and things, and things and things, so 5G networks are widely used. In such a situation, heterogeneous networks come into being. Heterogeneous networks can combine different types of networks into one network, so that different types of networks can communicate with each other, which can facilitate better services for users. In some embodiments, different types of networks can include, for example, the 4th generation mobile communication technology (4G) network and the 5G network; different types of networks can include, for example, the network of operator #1 and the network of operator #2.

The business path optimization method provided by the present invention can be applied to public business-to-business (ToB) scenarios and campus ToB scenarios.

FIG1 is a schematic diagram of the structure of a communication system according to some embodiments. As shown in FIG1, the communication system 100 includes a communication orchestration and scheduling system 101 and multiple performance analysis systems 102, each performance analysis system 102 corresponding to a single domain. For example, the communication system 100 includes a performance analysis system 102 corresponding to the operator's 5G virtual private network, a performance analysis system 102 corresponding to an industry-specific network, and a performance analysis system 102 corresponding to the Internet.

The communication orchestration and scheduling system 101 can be constructed based on the software defined network (SDN) technology/network function virtualization (NFV) technology. The communication orchestration and scheduling system 101 provides at least one of the following functions for the communication network by opening a preset interface (for example, a northbound interface): resource management function, performance monitoring function, security control function, alarm management function, and multiple single domain topology view display functions. The applications corresponding to the above functions can be deployed in the communication orchestration and scheduling system 101 in the form of independent components, and there is a loose coupling relationship between the applications corresponding to the above functions.

The following describes each function of the communication orchestration and scheduling system 101.

The resource management function means that the communication scheduling and dispatching system 101 can uniformly manage heterogeneous network resources and uniformly allocate resources for different types of services based on the principle of on-demand allocation and the granularity of services. The resource management function realizes the global resource sharing of heterogeneous network resources and also guarantees the resource requirements of services.

In some embodiments, the communication orchestration and scheduling system 101 can also provide more refined resource management functions for services in heterogeneous networks. For example, the communication orchestration and scheduling system 101 uses the services corresponding to the network slice as the granularity to uniformly allocate resources, and its implementation process can be: the communication orchestration and scheduling system 101 determines the network performance indicator model based on the service model, and reconstructs the network performance indicator model based on the network slice as the granularity, and determines the network performance indicator model corresponding to the network slice (recorded as the network slice performance indicator model). After that, the communication orchestration and scheduling system 101 uniformly allocates resources for services corresponding to different types of network slices based on the principle of on-demand allocation and the services corresponding to the network slice as the granularity.

The performance monitoring function refers to the communication orchestration and scheduling system 101 monitoring the performance of service paths in the heterogeneous network so that timely optimization and adjustment can be made when the performance of the service path is poor.

In some embodiments, the communication orchestration and scheduling system 101 can monitor and analyze the traffic of the service path in the heterogeneous network, so that the communication orchestration and scheduling system 101 can adjust the service path, thereby optimizing the entire network traffic of the heterogeneous network and improving the carrying capacity of the heterogeneous network.

The security control function means that when the performance of the service path is poor, the communication orchestration and scheduling system 101 optimizes and adjusts the service path in a timely manner to ensure that the performance of the service path can be maintained within a good range.

The alarm management function refers to the communication orchestration and scheduling system 101 monitoring the performance of nodes in the service path with poor performance, determining the faulty nodes in the service path with poor performance, and replacing the faulty nodes in the service path.

The function of displaying topological views of multiple single domains refers to the communication orchestration and scheduling system 101 drawing topological views of multiple single domains of a heterogeneous network based on the performance analysis results of the business sub-paths of multiple single domains and the path information of multiple business sub-paths (for example, the identification of the source node, the identification of the destination node, etc.), so that the actual performance of all business sub-paths in the heterogeneous network is clearer.

In some embodiments, the topology views of multiple single domains may be topology views of multiple single domains based on traffic. At this time, the communication orchestration and scheduling system 101 may automatically or manually adjust the service path based on the topology views of multiple single domains of traffic and a preset quality of service (QoS) strategy, thereby improving the bandwidth utilization in the heterogeneous network and improving the carrying capacity of the heterogeneous network.

In the embodiment of the present disclosure, the communication orchestration and scheduling system 101 is used to determine a network performance indicator model that matches the business model of the target business, send the network performance indicator model to the performance analysis system 102 of each single domain, receive the performance analysis results of the business sub-path from the performance analysis system 102 of each single domain, determine the performance analysis results of the target business path based on the performance analysis results, and optimize and adjust the target business path based on the performance analysis results of the target business path.

It should be noted that the target service path is composed of service sub-paths in each single domain.

In some embodiments, the target service may include at least one of the following services: low-latency service, voice service, activation service, traffic adjustment service, traffic scheduling service, quality of service related service, user management service, service level agreement (SLA) related service, and video service.

It can be understood that the communication orchestration and scheduling system 101 centrally controls the service sub-paths in multiple single domains, so that the topological results of the heterogeneous network, the total bandwidth of the heterogeneous network, and the total traffic of the heterogeneous network can be obtained based on the service sub-paths in multiple single domains. On the basis of the above, the communication orchestration and scheduling system 101 can calculate the transmission path for each service based on the service sub-paths in multiple single domains, manage the topological structure in the heterogeneous network based on the service sub-paths in multiple single domains, analyze the traffic in the heterogeneous network based on the service sub-paths in multiple single domains, and optimize and guide the traffic in the heterogeneous network based on the service sub-paths in multiple single domains. Therefore, the communication orchestration and scheduling system 101 can be used as a core integrated device in the communication system.

In some embodiments, the communication orchestration and scheduling system 101 is further used to determine at least one performance indicator concerned by the business model of the target business, and establish a network performance indicator model based on the at least one performance indicator.

Exemplarily, the at least one performance indicator includes at least one of latency, bandwidth utilization, number of freezes, and device performance parameters.

In some embodiments, the communication orchestration and scheduling system 101 is also used to determine the best transmission path based on the performance analysis results of the business sub-paths in each single domain when the performance analysis results of the target business path indicate that the current transmission path does not meet the performance requirements of the business model for the target business path, and determine the best transmission path as the first candidate path; when the performance analysis results of the first candidate path meet the performance requirements of the business model for the target business path, determine the first candidate path as the new target business path.

In some embodiments, the communication orchestration and scheduling system 101 is also used to send the performance analysis results of the business sub-path in each single domain to the management and control system 30 (as shown in Figure 1) when the performance analysis results of the first candidate path do not meet the performance requirements of the business model for the target business path, and receive scheduling instructions from the management and control system 30.

The scheduling instruction is used to indicate a new target service path.

In some embodiments, the communication scheduling and dispatching system 101 is further configured to determine based on the new target service path. Specify at least one service sub-path.

Among them, one business sub-path corresponds to a single domain.

In some embodiments, the communication orchestration and scheduling system 101 is also used to locate a faulty node in a target business path and replace the faulty node in the target business path when the performance analysis result of the target business path indicates that the current transmission path does not meet the performance requirements of the business model for the target business path.

In some embodiments, the communication orchestration and scheduling system 101 is also used to obtain multiple performance analysis results of the target business path within a historical time period, predict the performance analysis results of the target business path at a future moment based on the multiple performance analysis results of the target business path within the historical time period, and predict the failure moment of the target business path based on the performance analysis results of the target business path at a future moment.

In some embodiments, the communication orchestration and scheduling system 101 is further configured to perform a protection switching operation on the target service path in response to predicting that a failure occurs on the target service path at a target time.

The performance analysis system 102 can provide at least one of the following functions for the communication network: service identification function, indicator modeling function, quality monitoring function, problem tracing function, and fault repair. The performance analysis system 102 can be deployed in a central cloud, a distributed cloud, or an edge cloud.

The service identification function means that the performance analysis system 102 can obtain multi-dimensional indicator information of the service sub-path based on deep packet inspection (DPI) technology.

Among them, DPI technology can provide deep data detection functions for different applications, so as to obtain multi-dimensional indicator information of the business. Operation personnel can add DPI by deploying software and hardware probes. DPI can be applied to built-in scenarios and external scenarios. The following describes the DPI of built-in scenarios and the DPI of external scenarios respectively:

In the built-in scenario, the implementation process of the performance analysis system 102 obtaining multi-dimensional indicator information of the business sub-path based on DPI is as follows: the performance analysis system 102 detects the data in the single domain separately through the software and hardware probes pre-deployed in the network equipment at the edge of the single domain, and determines the multi-dimensional indicator information of the end-to-end business in response to the detection of the data in the single domain.

In an external scenario, the implementation process of the performance analysis system 102 obtaining multi-dimensional indicator information of a service sub-path based on DPI is as follows: the performance analysis system 102 detects the data in a single domain separately through software and hardware probes pre-deployed in network devices at the edge of the network, and determines the multi-dimensional indicator information of the end-to-end service in response to the detection of the data in the single domain.

In some embodiments, the terminal device (or access network device, or core network device) can also identify and locate poor quality users, poor quality cells, poor quality network elements, and poor quality slice call records through the multi-dimensional performance of end-to-end services in the network, or the multi-dimensional indicator information of end-to-end services in multiple single domains.

The indicator modeling function refers to the performance analysis system 102 receiving the business model of the target business from the communication orchestration and scheduling system 101, determining the identifier of the network performance indicator model based on the correspondence between the business model and the network performance indicator model, and requesting the network performance indicator model from the communication orchestration and scheduling system 101.

The quality monitoring function means that the performance analysis system 102 can perform performance analysis on the service sub-path of the target service in the corresponding single domain based on the network performance indicator model, and output the performance analysis result of the service sub-path of the single domain.

For example, the performance analysis system 102 may monitor bandwidth utilization of the service sub-path.

It should be noted that, for service sub-paths of different QoS service levels, the performance analysis system 102 may set different preset bandwidth utilizations and different preset tuning strategies.

The problem tracing function refers to the performance analysis system 102 based on the indicator information of the business path at multiple historical moments. The performance of the service path at multiple historical moments is analyzed to obtain performance analysis results of the service path at multiple historical moments, so that the performance analysis system 102 can determine the historical failure moment of the service path based on the performance analysis results of the service path at multiple historical moments.

Fault repair means that the performance analysis system 102 determines a faulty node in a service sub-path with poor performance and replaces the faulty node in the service sub-path.

Exemplarily, fault repair refers to the performance analysis system 102 optimizing and adjusting the service sub-path, and the implementation process of fault repair is as follows: the performance analysis system 102 obtains the bandwidth utilization of the service sub-path, and determines whether the bandwidth utilization of the service sub-path is less than the preset bandwidth utilization. When the bandwidth utilization of the service sub-path is less than the preset bandwidth utilization, the performance analysis system 102 instructs the SDN controller 60 (as shown in FIG. 1 ) to optimize and adjust the service sub-path based on the preset tuning strategy.

In the present disclosure, the performance analysis system 102 is used to perform performance analysis on the service sub-path of the target service in the corresponding single domain based on the network performance indicator model, output the performance analysis results of the service sub-path of the single domain, and send the performance analysis results to the communication orchestration and scheduling system 101.

In some embodiments, as shown in Figure 1, the communication system 100 may also include: multiple nodes 20, a management and control system 30, an orchestrator 40, a network management device 50, an SDN controller 60, an operator 5G virtual private network device 70, and an industry-specific network device 80.

The node 20 is used to determine performance parameters related to the node 20 and send the performance parameters to the performance analysis system 102 , so that the performance analysis system 102 can subsequently determine the performance analysis result of the service path based on the performance parameters related to the node 20 .

Node 20 is an execution device for optimizing and adjusting the service path. In some embodiments, adding a matching northbound interface to node 20 can realize automatic reporting and automatic configuration of performance parameters and optimization and adjustment of the service path.

In some embodiments, the node 20 may be a terminal (terminal equipment) or a user equipment (user equipment, UE) or a mobile station (mobile station, MS) or a mobile terminal (mobile terminal, MT), etc. Exemplarily, the terminal device may be a mobile phone, a tablet computer or a computer with a wireless transceiver function, or a virtual reality (virtual reality, VR) terminal, an augmented reality (augmented reality, AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a smart home, a vehicle-mounted terminal, etc.

In some embodiments, the plurality of nodes 20 may include nodes 20 in different networks. For example, the plurality of nodes 20 may include nodes 20 in a 4G network and nodes 20 in a 5G network. For another example, the plurality of nodes 20 may include nodes in a network of operator #1 and nodes in a network of operator #2.

The management and control system 30 is used to receive the performance analysis results of the service sub-paths from each single domain, determine a new service path based on the performance analysis results of the service sub-paths of each single domain, and send the new service path to the communication orchestration and scheduling system 101.

The orchestrator 40 is configured to receive the service sub-paths of each single domain from the communication orchestration and scheduling system 101 , and send the service sub-paths of each single domain to the network management device 50 or the SDN controller 60 .

The network management device 50 or the SDN controller 60 is used to receive the service sub-paths of each single domain from the communication orchestration and scheduling system 101 , and can also be used to receive the service sub-paths of each single domain from the orchestrator 40 .

It should be noted that the orchestrator 40, the network management device 50, and the SDN controller 60 are all related devices, which can be understood by referring to the relevant technologies, and the present disclosure will not elaborate on them.

In some embodiments, the communication orchestration and scheduling system 101 is also used to manage SDN service paths and non-SDN service paths. For example, the communication orchestration and scheduling system 101 manages SDN service paths through the SDN controller 60 and manages non-SDN service paths through the network management device 50.

In some embodiments, the communication system can be applied to a target network. The target network can include at least one of the following: 4G network, 5G network, optical network, passive optical network (PON), Internet protocol (IP), and the Internet.

It should be noted that the communication system 100 described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. A person of ordinary skill in the art can appreciate that with the evolution of network architecture and the emergence of new communication systems, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

In the related art, since heterogeneous networks include many different types of networks, there are many types of services in heterogeneous networks, the services are very different, the services are widely distributed, and they are difficult to control, resulting in that the service paths carrying services in heterogeneous networks cannot adapt well to service needs, especially for low-latency services, which are prone to problems such as excessive latency and/or data packet loss, resulting in reduced service performance. In order to solve the problems existing in the above-mentioned related art, the embodiments of the present disclosure propose a service path optimization method, through which the service path can be optimized more accurately, so that the service path can better support service needs, thereby improving service performance.

FIG2 is a flow chart of a method for optimizing a service path according to some embodiments. As shown in FIG2 , the method includes S201 to S206 .

S201. The communication orchestration and scheduling system 101 determines a network performance indicator model that matches a service model of a target service.

In some embodiments, the implementation process of S201 may be: the communication orchestration and scheduling system 101 determines a business model and determines at least one performance indicator that the business model focuses on. The communication orchestration and scheduling system 101 performs optimization operations such as training and testing on an initial model based on at least one performance indicator until the optimized model meets the preset requirements, and determines that the optimized model is a network performance indicator model.

In some other embodiments, the implementation process of S201 may be: the communication orchestration and scheduling system 101 determines a service model and determines at least one performance indicator that the service model focuses on. The communication orchestration and scheduling system 101 determines, from the model set, a model that analyzes the performance analysis results of the service path based on at least one performance indicator as a network performance indicator model.

Exemplarily, in the process of the communication orchestration and scheduling system 101 determining the implementation of the network performance indicator model, the communication orchestration and scheduling system 101 may also restrict the input parameters of the network performance indicator model so that the input parameters can better adapt to the calculation of the network performance indicator model, thereby improving the accuracy of the performance analysis results of the service path output by the network performance indicator model.

For example, taking the input parameter including delay as an example, the communication orchestration and scheduling system 101 may limit the delay input to the network performance indicator model to be within the range of 0 seconds to 0.02 seconds. In this case, the communication orchestration and scheduling system 101 may remove the information that is not within the above range from the delay information of the service path, retain the delay information of the service path within the above range, and use the retained delay information as the input of the network performance indicator model.

In some embodiments, the communication scheduling and dispatching system 101 determines at least one performance indicator of the service model as follows: the communication scheduling and dispatching system 101 obtains multiple service models and multiple services. At least one performance indicator of concern to the model, and based on the information of multiple services and the at least one performance indicator of concern to the multiple services, a corresponding relationship between the service model and the performance indicator is established. The communication orchestration and scheduling system 101 can determine at least one performance indicator of concern to the service model based on the service model of the present disclosure and the corresponding relationship between the service model and the performance indicator.

In some embodiments, the target service may include at least one of the following: low-latency service, voice service, activation service, traffic adjustment service, traffic scheduling service, QoS-related service, user management service, service level agreement (SLA)-related service, and video service. It should be noted that the target service may also include other service models (e.g., broadcast service), which is not limited in the present disclosure.

S202. The communication orchestration and scheduling system 101 sends a network performance indicator model to each single domain.

Correspondingly, each single domain receives the network performance indicator model from the communication orchestration and scheduling system 101 .

S203 . The performance analysis system 102 corresponding to each single domain performs performance analysis on the service sub-path of the target service in the corresponding single domain based on the network performance indicator model, and outputs the performance analysis result of the service sub-path of each single domain.

In some embodiments, as shown in FIG3 , the implementation process of S203 may be: the performance analysis system 102 corresponding to a single domain associates the configuration requirements of at least one indicator (i.e., multi-dimensional data) of the service sub-path with the service model through cluster analysis or topological association, and determines the configuration requirements corresponding to the network performance indicator model based on the correspondence between the service model and the network performance indicator model. The performance analysis system 102 may obtain the indicator information of the service sub-path based on service flow detection and multi-dimensional data collection, and filter the indicator information based on the configuration requirements to obtain at least one indicator of the service sub-path. The performance analysis system 102 analyzes the performance of the service sub-path based on at least one indicator of the service sub-path and the network performance indicator model to obtain a performance analysis result of the service sub-path.

In some embodiments, the performance analysis results can be predicted based on multiple aspects such as network status, traffic flow, customer experience, customer behavior, etc. to obtain a comprehensive result.

3, the performance analysis system 102 may also determine a faulty node in a service subpath based on the performance analysis result of the service subpath. When the performance analysis system 102 determines that there is a faulty node in the service subpath, the performance analysis system 102 replaces the faulty node, thereby achieving internal optimization of the service subpath within a single domain.

S204: The communication orchestration and scheduling system 101 obtains a performance analysis result of a service sub-path of each single domain.

In some embodiments, the performance analysis result of the service sub-path is used to represent the comprehensive evaluation result of at least one performance indicator of the service sub-path. The performance analysis result is represented by a numerical value, for example, the performance analysis result of service sub-path #1 is 80.

S205 . The communication orchestration and scheduling system 101 determines a performance analysis result of the target service path based on the performance analysis result.

It should be noted that the target service path is composed of service sub-paths of each single domain.

Exemplarily, the target service path may be composed of service sub-path #1 of single domain #1, service sub-path #2 of single domain #2, and service sub-path #3 of single domain #3.

In some embodiments, the communication orchestration and scheduling system 101 may also obtain path node information of the service sub-path of each single domain, so that the communication orchestration and scheduling system may determine the target service path based on the node information of the service sub-path.

Exemplarily, the node information may include: identifications of at least two nodes 20 constituting the service sub-path. The node information may also include other information (eg, fault information of at least two nodes 20 constituting the service sub-path), which is not limited in the present disclosure.

S206 , the communication orchestration and scheduling system 101 optimizes and adjusts the target service path based on the performance analysis result of the target service path.

The optimization adjustment of the target service path by the communication orchestration and scheduling system includes: replacing the target service path, and/or replacing the faulty node in the service path.

In some embodiments, the implementation process of S206 may be: the communication orchestration and scheduling system 101 may determine the performance analysis results of the business sub-path based on each single domain, determine the performance analysis results of multiple transmission paths adapted to the business model, and determine from the multiple transmission paths the transmission path with the best performance analysis result and that meets the performance requirements of the business model for the target business path as the new target business path.

In other embodiments, the implementation process of S206 may be: the communication orchestration and scheduling system 101 determines the faulty node in the target service path, and obtains at least one node 20 that can replace the faulty node. The communication orchestration and scheduling system 101 determines a target node from the at least one node 20 as a new node 20 in the target service path. The communication orchestration and scheduling system 101 and the performance analysis system 102 may periodically perform S201 to S206, so that the target service path can be dynamically optimized to better ensure the performance of the target service path.

In the technical solution provided by the embodiment of the present disclosure, the communication orchestration and scheduling system 101 can determine a network performance indicator model that matches the business model of the target business, and send the network performance indicator model to each single domain, so that each single domain can output the performance analysis results of the business sub-path of each single domain based on the network performance indicator model. Compared with determining the network performance indicators related to the target business based on manual experience, the business model can more accurately output more comprehensive network performance indicators related to the target business. The network performance indicator model determined based on the business model can refer to the comprehensive indicators related to the target business in the process of determining the performance analysis results of the business sub-path, so that the performance analysis results determined based on the network performance indicator model can more accurately reflect the actual performance of the business sub-path.

Next, the communication orchestration and scheduling system 101 can determine the performance analysis result of the target service path based on the performance analysis result of each single domain. Based on the high accuracy of the performance analysis result of the service sub-path, the performance analysis result of the target service path can accurately reflect the real performance of the target service path.

Finally, the communication orchestration and scheduling system 101 can optimize and adjust the target service sub-path based on the performance analysis results of the target service path with higher accuracy, so that the target service path can better adapt to the service requirements in the heterogeneous network (for example, bandwidth requirements, traffic requirements, resource utilization requirements), thereby improving service performance and network performance.

In some embodiments, as shown in S201, the communication orchestration and scheduling system 101 may determine a network performance indicator model that matches the service model of the target service. The present disclosure embodiment may provide a possible implementation of S201 based on the method embodiment shown in FIG.

FIG4 is a flowchart of another method for optimizing a service path according to some embodiments. As shown in FIG4 , the implementation process of the communication orchestration and scheduling system 101 determining a network performance indicator model (ie, S201) that matches the service model of the target service may include S401 to S402.

S401. The communication orchestration and scheduling system 101 determines at least one performance indicator that a business model focuses on.

In some embodiments, at least one performance indicator includes latency, bandwidth utilization, number of freezes, and At least one of the equipment performance parameters.

The at least one performance indicator may also include at least one of the following: path type, slice information, device location information, service level agreement (SLA), and user information. It should be noted that the above is only an exemplary description of at least one performance indicator, and the at least one performance indicator may also include other performance indicators (for example, network element information), and the present disclosure does not make any limitation on this.

In some embodiments, the device performance parameter may include at least one of the following: the number of device failures, the power consumption of the device, and the throughput of the device. It should be noted that the above is only an exemplary description of the device performance parameter, and the device performance parameter may also include other parameters (for example, the concurrency of the device), and the present disclosure does not make any limitation on this.

S402: The communication orchestration and scheduling system establishes a network performance indicator model based on at least one performance indicator.

In some embodiments, the implementation process of S402 may be: the communication orchestration and scheduling system 101 obtains at least one performance indicator of each test service path in the test sample set as a training sample, and performs multiple iterative training on the initial model based on at least one performance indicator of each first service path, until the number of training times reaches a preset number, and determines that the initial model is the candidate model.

The communication scheduling and scheduling system 101 obtains at least one performance indicator of each verification service path in the verification sample set as a test sample, and tests the candidate model based on at least one performance indicator of each second service path to obtain a test result. If the test result meets the preset conditions, the communication scheduling and scheduling system 101 determines that the candidate model is a network performance indicator model.

In some embodiments, after establishing a network performance indicator model based on at least one performance indicator, the communication orchestration and scheduling system 101 may also adjust the network performance indicator model based on the slice information. At this time, the communication orchestration and scheduling system 101 may send the adjusted network performance indicator model to the performance analysis system 102.

In the technical solution provided by the embodiment of the present disclosure, the communication orchestration and scheduling system 101 determines at least one performance indicator of concern to the business model, and establishes a network performance indicator model based on the at least one performance indicator. The network performance indicator model determined in this way can be more in line with the business, so that the performance analysis results determined based on the network performance indicator model can more truly reflect the actual situation, and there is no need for operating personnel to establish the network performance indicator model based on experience, which shortens the time for establishing the network performance indicator model and improves the efficiency of establishing the network performance indicator model.

In some embodiments, as shown in S206, the communication orchestration and scheduling system 101 may optimize and adjust the target service path based on the performance analysis result of the target service path. The embodiment of the present disclosure may provide a possible implementation of S206 based on the method embodiment shown in FIG2 .

FIG5 is a flowchart of another method for optimizing a service path according to some embodiments. As shown in FIG5 , the implementation process of the communication orchestration and scheduling system 101 optimizing and adjusting the target service path (ie, S206) based on the performance analysis result of the target service path may include S501 to S505.

S501. The communication orchestration and scheduling system 101 determines whether a performance analysis result of a target service path indicates whether a current transmission path meets the performance requirements of a service model for the target service path.

In some embodiments, the performance requirement of the business model for the target business path may be that the performance analysis result is greater than or equal to a preset performance threshold. For example, when the performance analysis result of the target business path #2 is 95 and the preset performance threshold is 98, the communication orchestration and scheduling system 101 may determine that the performance analysis result of the target business path #2 indicates that the current transmission path does not meet the performance requirement of the business model for the target business path.

Exemplarily, in the case where the performance analysis result is used to characterize the analysis result of the bandwidth utilization of the service path, the communication orchestration and scheduling system 101 can determine whether the performance analysis result of the service path (e.g., 85%) is greater than or equal to the target threshold (e.g., 80%). If the performance analysis result of the bandwidth utilization of the service path is determined to be greater than or equal to the target threshold, the communication orchestration and scheduling system determines that the performance analysis result of the target service path indicates that the current transmission path meets the performance requirements of the service model for the target service path.

If it is determined that the performance analysis result of the target service path indicates that the current transmission path meets the performance requirements of the service model for the target service path, the communication orchestration and scheduling system 101 does not optimize the service path and ends the process.

If it is determined that the performance analysis result of the target service path indicates that the current transmission path does not meet the performance requirements of the service model for the target service path, the communication orchestration and scheduling system 101 executes S502.

S502: The communication orchestration and scheduling system 101 determines an optimal transmission path based on the performance analysis result of the service sub-path of each single domain.

In some embodiments, the implementation process of S502 may be: the communication orchestration and scheduling system 101 first determines each transmission path among multiple transmission paths adapted to the business model based on the business sub-path of each single domain, and determines the performance analysis result of each transmission path based on the performance analysis result of the business sub-path included in each transmission path. The communication orchestration and scheduling system 101 determines the transmission path with the best performance analysis result from the multiple transmission paths.

In some embodiments, the plurality of transmission paths may include: a transmission path of operator #1, a transmission path of operator #2, and a transmission path of operator #3.

In other embodiments, the multiple transmission paths may include: a 4G transmission path and a 5G transmission path.

S503: The communication scheduling and dispatching system 101 determines the best transmission path as the first candidate path.

The communication scheduling and dispatching system 101 can also sort the multiple transmission paths from large to small based on the performance analysis results to obtain a result sequence, and determine the second transmission path in the result sequence as the second candidate path. The second candidate path can be used as an alternative path to the first candidate path.

S504: The communication orchestration and scheduling system 101 determines whether the performance analysis result of the first candidate path meets the performance requirement of the service model for the target service path.

The performance requirements of the business model for the target business path can be understood by referring to the description of the corresponding position above, which will not be repeated here.

If it is determined that the performance analysis result of the first candidate path meets the performance requirement of the service model for the target service path, the communication orchestration and scheduling system 101 executes S505 .

S505: The communication orchestration and scheduling system 101 determines the first candidate path as a new target service path.

After determining that the first candidate path is the new target service path, the communication scheduling and dispatching system 101 replaces the original target service path with the new target service path to ensure the stability of the service.

In the technical solution provided by the embodiment of the present disclosure, when the performance analysis result of the target service path indicates that the current transmission path does not meet the performance requirements of the business model for the target service path, the communication orchestration and scheduling system 101 determines the best transmission path based on the performance analysis results of the service sub-paths of each single domain, and determines the best transmission path as the first candidate path. Then, when the performance analysis result of the first candidate path meets the performance requirements of the business model for the target service path, the communication orchestration and scheduling system 101 determines the first candidate path as the new target service path, so that the new service path determined by the communication orchestration and scheduling system 101 can be guaranteed to have better performance as much as possible, so that the service path can better support the needs of the service.

In some embodiments, as shown in S504, the communication orchestration and scheduling system 101 determines whether the performance analysis result of the first candidate path meets the performance requirements of the business model for the target business path. When it is determined that the performance analysis result of the first candidate path does not meet the performance requirements of the business model for the target business path, the communication orchestration and scheduling system 101 interacts with the management and control system 30 to determine a new target business path.

Figure 6 is a flowchart of another service path optimization method according to some embodiments. As shown in Figures 5 and 6, when the communication orchestration and scheduling system 101 determines that the performance analysis result of the first candidate path does not meet the performance requirements of the service model for the target service path, the implementation process of determining a new target service path may include S601 to S602.

S601 : The communication orchestration and scheduling system 101 sends the performance analysis result of the service sub-path of each single domain to the management control system 30 . Accordingly, the management control system 30 receives the performance analysis result of the service sub-path of each single domain from the communication orchestration and scheduling system 101 .

After receiving the performance analysis results of the service sub-paths of each single domain from the communication orchestration and scheduling system, the management and control system 30 may provide a new target service path for the target service based on the performance analysis results of the service sub-paths of each single domain.

S602 : The management and control system 30 sends a scheduling instruction to the communication orchestration and scheduling system 101 . Correspondingly, the communication orchestration and scheduling system 101 receives the scheduling instruction from the management and control system 30 .

After receiving the new target service path, the communication scheduling and dispatching system 101 replaces the original target service path with the new target service path to ensure the stability of the service.

The above technical solution brings at least the following beneficial effects: when the performance analysis result of the first candidate path does not meet the performance requirements of the business model for the target business path, the communication orchestration and scheduling system 101 sends the performance analysis results of the business sub-path of each single domain to the management and control system 30, and receives scheduling instructions from the management and control system 30. In this way, when the performance analysis result of the first candidate path does not meet the performance requirements of the business model for the target business path, it can also be guaranteed that the new business path has better performance, so that the business path can better support business needs.

In some embodiments, after the communication orchestration and scheduling system 101 determines or receives a new service path, the communication orchestration and scheduling system 101 may also send the service sub-path corresponding to the target single domain in the new service path to the target single domain, so that the target single domain can replace the original service sub-path by itself.

FIG7 is a flowchart of another method for optimizing a service path according to some embodiments. As shown in FIG6 and FIG7 , the implementation process of the communication orchestration and scheduling system 101 sending a service sub-path corresponding to a target single domain to a target single domain may include S701 to S702.

S701. The communication orchestration and scheduling system 101 determines at least one service sub-path based on a new target service path.

In some embodiments, the communication orchestration and scheduling system 101 may divide the new service path into service sub-path #1, service sub-path #2, and service sub-path #3. Service sub-path #1 corresponds to single domain #1, service sub-path #2 corresponds to single domain #2, and service sub-path #3 corresponds to single domain #3.

S702 : The communication orchestration and scheduling system 101 sends the service sub-path corresponding to the target single domain to the target single domain. Correspondingly, the target single domain receives the service sub-path corresponding to the target single domain from the communication orchestration and scheduling system 101 .

In combination with the above example, the communication orchestration and scheduling system 101 can send service subpath #1 to single domain #1, and correspondingly, single domain #1 receives service subpath #1 from the communication orchestration and scheduling system. The communication orchestration and scheduling system 101 can send service subpath #2 to single domain #2, and correspondingly, single domain #2 receives service subpath #2 from the communication orchestration and scheduling system 101. The communication orchestration and scheduling system 101 can send service subpath #3 to single domain #3, Correspondingly, single domain #3 receives service sub-path #3 from communication orchestration and scheduling system 101 .

The above technical solution brings at least the following beneficial effects: the communication orchestration and scheduling system 101 determines at least one service sub-path based on the new target service path, and sends the service sub-path corresponding to the target single domain to the target single domain, so that the target single domain can replace the original service sub-path by itself.

In some embodiments, as shown in S206, the communication orchestration and scheduling system 101 optimizes and adjusts the target service path based on the performance analysis result of the target service path. The embodiment of the present disclosure can provide another possible implementation of S206 based on the method embodiment shown in FIG.

FIG8 is a flowchart of another method for optimizing a service path according to some embodiments. As shown in FIG8 , the implementation process of optimizing and adjusting the service path (ie, S206 ) by the communication orchestration and scheduling system 101 may include S801 to S803 .

S801. The communication orchestration and scheduling system 101 determines whether a performance analysis result of a target service path indicates whether a current transmission path meets the performance requirements of a service model for the target service path.

If it is determined that the performance analysis result of the target service path indicates that the current transmission path meets the performance requirements of the service model for the target service path, the communication orchestration and scheduling system does not optimize the service path and ends the process.

If it is determined that the performance analysis result of the target service path indicates that the current transmission path does not meet the performance requirements of the service model for the target service path, the communication orchestration and scheduling system executes S802.

S802: The communication orchestration and scheduling system 101 locates a faulty node in a service path.

In some embodiments, the implementation process of S802 may be: the communication orchestration and scheduling system 101 obtains the fault indicators (for example, the number of failures) of at least two nodes 20 in the service path, and performs a second operation on each of the at least two nodes 20 to obtain the faulty node in the service path.

The second operation is explained below: the communication scheduling and dispatching system 101 determines whether the fault indicator of the target node meets the fault preset condition. If the fault indicator of the target node meets the fault preset condition, the communication scheduling and dispatching system 101 determines that the target node is a faulty node. The target node is any one of the at least two nodes 20.

S803: The communication orchestration and scheduling system 101 replaces the faulty node in the service path.

In some embodiments, the implementation process of S803 may be: the communication orchestration and scheduling system 101 determines a replaceable node for the failed node, and determines a replacement node from the replaceable nodes. The communication orchestration and scheduling system 101 replaces the failed node with a replacement node.

The above technical solution brings at least the following beneficial effects: when the performance analysis results indicate that the current transmission path does not meet the performance requirements of the business model for the business path, the communication orchestration and scheduling system 101 locates the faulty node in the business path and replaces the faulty node in the business path, thereby ensuring that the node 20 used to establish the business path is a normal node, so that the business path can better support the business needs.

In some embodiments, the communication orchestration and scheduling system 101 can also determine the performance analysis results of the business path at a future time, and based on the performance analysis results of the business path at a future time, monitor the fault conditions of the business path, so that the communication orchestration and scheduling system can optimize and adjust the business path in a timely manner, thereby improving the reliability of the business path.

FIG9 is a flowchart of another method for optimizing a service path according to some embodiments. As shown in FIG2 and FIG9 , the communication orchestration and scheduling system 101 may also determine a performance analysis result of the service path at a future time, and based on the performance analysis result of the service path at a future time, the implementation process of monitoring the fault condition of the service path may include S901 to S904.

S901. The communication orchestration and scheduling system 101 obtains multiple performance analysis results of a service path within a historical time period.

In some embodiments, the implementation process of S901 may be: the communication orchestration and scheduling system 101 obtains at least one performance indicator of the service path within a historical time period, and inputs the obtained at least one performance indicator of the service path within the historical time period into a network performance indicator model to obtain multiple performance analysis results of the service path within the historical time period.

S902 . The communication scheduling and dispatching system 101 predicts the performance analysis results of the service path at a future time based on multiple performance analysis results of the service path in a historical time period.

In some embodiments, the implementation process of S902 may be: the communication orchestration and scheduling system 101 draws a performance analysis graph for characterizing the change trend of the business path based on multiple performance analysis results of the business path in a historical time period, and predicts the performance analysis results of the business path at a future moment based on the performance analysis graph.

S903 . The communication orchestration and scheduling system 101 predicts the failure time of the target service path based on the performance analysis result of the service path at the future time.

If it is determined that the communication orchestration and scheduling system 101 has not predicted the failure time of the target service path, the communication orchestration and scheduling system ends the process.

In some embodiments, if it is determined that communication orchestration and scheduling system 101 predicts that a target service path fails at a target time, communication orchestration and scheduling system 101 executes S904 .

S904: The communication orchestration and scheduling system 101 performs a protection switching operation on the target service path.

In some embodiments, the implementation process of S904 may be: the communication orchestration and scheduling system 101 determines the performance analysis results of multiple transmission paths that can replace the service path at a future time, and uses the transmission path with the best performance analysis result at a future time among the multiple transmission paths as the protection path. The communication orchestration and scheduling system 101 updates the service path to the protection path.

It should be noted that the communication scheduling and dispatching system 101 can perform the protection switching operation before the target time, or can perform the protection switching operation at the target time.

In the technical solution provided by the embodiment of the present disclosure, the communication orchestration and scheduling system 101 obtains multiple performance analysis results of the service path in the historical time period, and predicts the performance analysis results of the service path at a future time based on the multiple performance analysis results of the service path in the historical time period. In this way, the communication orchestration and scheduling system 101 can predict the failure time of the target service path based on the performance analysis results of the service path at a future time, so that the communication orchestration and scheduling system 101 can perform protection switching operations on the target service path in a timely manner, so as to replace the new service path in a timely manner, thereby improving the stability of the service path.
