Detailed ways

The technical solution of the present disclosure will be described in further detail below through the accompanying drawings and examples.

The inventor found that the first type of OAM information reflects the overall resource consumption of the device when it carries all network services, and cannot distinguish how many resources different services consume and the impact on specific services. How big. When data packets experience severe delays and packet loss during transmission, or when data packets are dropped midway and fail to reach the end point, the server cannot obtain real-time type II OAM information.

In related technologies, the approximate status of network service operation can only be indirectly and roughly inferred based on the first type of OAM information uploaded under specified conditions, which is contrary to the original intention of using telemetry to collect OAM information in real time. The server cannot monitor the operation of both equipment and service path nodes in real time at the same time, which leads to a single and one-sided analysis of the subsequent network operating status, making it difficult to accurately locate the problem.

In response to the above problems, the present disclosure proposes an OAM information processing method to improve the timeliness and comprehensiveness of OAM information collection, thereby enabling more timely and accurate positioning of problems.

A flow chart of some embodiments of the OAM information processing method of the present disclosure is shown in Figure 1.

In step 102, the network node obtains OAM evaluation parameters. In some embodiments, the OAM evaluation parameters may be carried in the header of the NSH message and transmitted between SFC nodes. In some embodiments, the network node can extract the OAM evaluation parameters from predetermined fields in the NSH message header after obtaining the NSH message.

In some embodiments, the OAM evaluation parameters include the threshold of the service SLA, the weight distribution value of the service SLA, the OAM weight distribution value of the device, and the preset comprehensive threshold.

In some embodiments, the SFC NSH message header can be extended, and the SFC source node sets the following information in the SFC NSH message header:

Type of business SLA;

Business SLA threshold;

The weight distribution value of business SLA;

The OAM weight allocation value of the device;

Preset comprehensive threshold.

When SFC generates an NSH message, it carries the above-mentioned OAM evaluation parameters through its message header. In some embodiments, the payload field of the NSH message carries user data, and then the OAM evaluation parameters can be transmitted between SFC nodes along with the user data. .

In some embodiments, the OAM evaluation parameters carried in the SFC NSH message header are programmable parameters. Users can set and generate configuration information, set or modify the OAM evaluation parameters corresponding to the types of each service SLA, and the corresponding OAM evaluation parameters corresponding to different types of service SLAs. For example, the threshold and weight distribution values can be different, thereby improving the flexibility and controllability of OAM information reporting.

In some embodiments, the above-mentioned preset comprehensive threshold is the threshold of comprehensive information of service and device OAM.

In step 104, the network node determines the OAM comprehensive evaluation value based on the service OAM information, device OAM information and OAM evaluation parameters. In some embodiments, the service OAM evaluation value and the device OAM evaluation value can be determined separately, and then the two are combined to determine the comprehensive OAM evaluation value. The business OAM evaluation value reflects the deviation of the service status from the normal state; the equipment OAM evaluation value reflects the deviation of the service status from the normal status.

In some embodiments, the network node also collects its own device OAM information. In some embodiments, device OAM information may include multiple dimensions, such as CPU usage, memory usage, packet loss rate per second, throughput, power supply heat dissipation, etc.

In some embodiments, the service OAM evaluation value and the device OAM evaluation value can be multiplied as the OAM comprehensive evaluation value. Considering that the OAM evaluation dimensions of the service and the device are different, the result of multiplying the two is used as the OAM comprehensive evaluation. The value can reduce the excessive impact of one item and improve the accuracy of the evaluation value reflecting the business and equipment status.

In step 106, the network node determines the OAM information reporting method to be adopted based on the OAM comprehensive evaluation value, and executes the corresponding reporting method. In some embodiments, the OAM information includes reported service OAM information and device OAM information. In some embodiments, the reporting method includes directly reporting the OAM information to the server by the current network node, or forwarding the OAM information to the destination node through a data packet, and the destination node reports the OAM information to the server. In some embodiments, the OAM comprehensive evaluation value may be called ISDOEV.

Based on the method in the embodiment shown above, the status of services and equipment can be comprehensively considered, and then an appropriate OAM information reporting method can be selected to reduce the lack of OAM information, improve the accuracy of network operating status analysis, and improve the accuracy of problem location. and efficiency.

In some embodiments, the operation in step 106 above may include: comparing the OAM comprehensive evaluation value with a preset comprehensive threshold. When the OAM comprehensive evaluation value is greater than or equal to the preset comprehensive threshold, the current node reports the OAM information directly to the server. For example, a dedicated OAM packet carries the business OAM information and the device OAM information and sends it to the telemetry server.

Based on the method in the embodiment shown above, the network node can report the service OAM information and device OAM information to the server by itself when the comprehensive status of the service and the device is not good, so that the server can learn the service in time , the overall status of the equipment is poor, avoiding the loss of OAM information, improving the accuracy of network operating status analysis, and improving the accuracy and efficiency of problem location. In addition, by comparing with the preset comprehensive threshold, it also avoids large-scale reporting of OAM information under normal circumstances, avoids waste of server processing resources, and further improves server processing efficiency.

In some embodiments, the above step 106 may also include: in the case where the OAM comprehensive evaluation value is less than the preset comprehensive threshold, determining to transmit the device OAM information through the data packet. In some embodiments, the network node encapsulates the collected device OAM information in a data packet, and forwards the data packet to the end point of the SFP (Service Function Path). In some embodiments, the OAM information forwarded to the SFP along with the data packet may also include service OAM information. In some embodiments, the service OAM information and the device OAM information can be added to the original first data packet to generate a second data packet; and the second data packet is sent to the destination node through the service chain. In some embodiments, the above-mentioned first data packet is an original data packet received by the node executing the current method.

Based on the method in this embodiment, when the comprehensive status of the business and equipment is normal, the OAM information including the equipment OAM information can be forwarded with the data packet, thereby avoiding reporting OAM to the server when the equipment and business are normal. information, reducing the data processing pressure on the server and improving the effective use of server computing resources.

In some embodiments, in the above-mentioned step 104, a flow chart of some embodiments of obtaining the service OAM evaluation value is shown in Figure 2A.

In step 211, the service OAM ratio value is determined based on the service OAM information and the threshold of the service SLA.

In some embodiments, the service OAM information a can be divided by the corresponding service SLA threshold b to obtain the service OAM ratio value a'. In some embodiments, if a’>1, the current service status is good, and if a’<1, the current service status is poor.

In some embodiments, the business OAM information can be represented by multiple dimensions, including a ₁ ,... a _p , where p is the number of dimensions of the business OAM information, which is a positive integer greater than 1. Each dimension corresponds to a business SLA threshold b ₁ , ... b _p , and the OAM ratio value a ₁ ', ... a _p ' of each dimension is calculated, where a ₁ '=a ₁ /b ₁ ... ...a _p '=a _p /b _p .

In step 212, the service OAM weighted ratio value a" is determined based on the service OAM ratio value a' and the weight distribution value k of the service SLA.

In some embodiments, the weight allocation value of the service SLA includes the weight corresponding to each dimension, such as k ₁ ,...k _p , and then the service OAM ratio value of each dimension is multiplied by its corresponding weight to obtain the corresponding dimension. The OAM weighted ratio value a ₁ ″=k ₁ *a ₁ '...a _p ”=k _p *a _p '. In some embodiments, the weight corresponding to a dimension with high importance is higher than the weight corresponding to a dimension with low importance.

In step 213, the service OAM evaluation value A is determined according to the service OAM weighted ratio value of each dimension.

In some embodiments, the OAM weighted ratio values of the services in each dimension can be multiplied to obtain the service OAM evaluation value A, such as A=a ₁ "*... a _p ".

Based on the method in the above embodiment, the business OAM can be analyzed by dimensions first to obtain the business status of each dimension, and then the weighted ratio value can be obtained according to the importance of each dimension, and then the weighted ratio value of each dimension can be combined to determine the business OAM Evaluation value. The OAM evaluation value can reflect the status of business OAM from various dimensions, and then serve as the data basis for subsequent judgments on whether to directly report business OAM, thereby improving the accuracy of reporting timing.

In some embodiments, in the above-mentioned step 104, a flow chart of some embodiments of obtaining the device OAM evaluation value is shown in Figure 2B.

In step 221, the OAM weighting ratio value C of the device is determined based on the device OAM information c and the OAM weight allocation value r of the device.

In some embodiments, the device OAM information c can be divided by the corresponding device threshold d to obtain the device OAM ratio value c'. Further, the device is determined based on the device OAM ratio value c' and the device's OAM weight allocation value r. OAM weighted ratio value c”.

In some embodiments, if c'>1, the current device status is better, and if c'<1, the current device status is worse.

In some embodiments, the device OAM information can be represented by multiple dimensions, including c ₁ ,...c _q , where q is the number of dimensions of the device OAM information and is a positive integer greater than 1. Each dimension corresponds to a device threshold d ₁ ,...d _q , and the device OAM ratio value c ₁ ',...c _q ' of each dimension is calculated, where c ₁ '=c ₁ /d ₁ ... c _q '=c _q /d _q .

In some embodiments, the OAM weight allocation value of the device includes the weight corresponding to each dimension, such as r ₁ , ... r _q , and then the device OAM ratio value of each dimension is multiplied by its corresponding weight to obtain the corresponding dimension. The device OAM weighted ratio value c ₁ ”=r ₁ *c ₁ '...c _q ”=r _q *c _q '. In some embodiments, the weight corresponding to a dimension with high importance is higher than the weight corresponding to a dimension with low importance.

In step 222, the device OAM evaluation value is determined according to the OAM weighted ratio value of the device in each dimension. In some embodiments, the device OAM weighted ratio values of each dimension can be multiplied to obtain the device OAM evaluation value C, such as C=c _{1 ″} *...c _q ”.

In some embodiments, based on what is shown in Figures 2A and 2B, the OAM comprehensive evaluation value=A*C.

Based on the method in the above embodiment, the device OAM can be analyzed dimensionally first to obtain the device status of each dimension, and then the device OAM evaluation value of the device can be determined based on the device status of each dimension and its importance. The OAM evaluation value can It reflects the status of each dimension of the device and serves as the data basis for subsequent judgments on whether to directly report the device to OAM, thereby improving the accuracy of determining the reporting timing.

A schematic diagram of some embodiments of the OAM information processing method of the present disclosure is shown in Figure 3. The source node and the end device of the SFC include two VNF (Virtual Network Function, virtualized network function) nodes SF (Service Function). service function) entity as an example.

When the SFC source node 31 generates an NSH message based on the data from the source user, it extends the header of the NSH message sent to SF1 to carry OAM evaluation parameters such as the type of service SLA; in addition, the payload part of the message carries User data and classified OAM information. When the message reaches the intermediate node SF1 of the SFC, the node determines the OAM comprehensive evaluation value and compares it with the predetermined comprehensive threshold.

If SF1 determines that the OAM comprehensive evaluation value ≥ the predetermined comprehensive threshold, the OAM message is used to carry the device OAM information and service OAM information of SF1 through the payload part and report it to the server 30 .

If SF1 determines that the OAM comprehensive evaluation value is < the predetermined comprehensive threshold, the OAM information of the device is carried in the NSH message and sent to the next node on the SFC, such as SF2.

Assuming that after SF2 determines the OAM comprehensive evaluation value and determines that the OAM comprehensive evaluation value is < the predetermined comprehensive threshold, SF2's device OAM information is added to the payload part of the NSH message. When the SFC end device 34 (which may be a router) receives the NSH message, it parses the OAM information of each device in the payload and the SFC service end-to-end OAM information, carries it through the payload part of the OAM message, and reports it to the server 30 .

In the related technology, only the performance of the device is analyzed and collected along the way. The service OAM information is not uploaded to the server until the data message reaches the end point; the device OAM information collected at the intermediate node has a single dimension and no business OAM information. Available for comprehensive analysis. Compared with related technologies, the method in the embodiment of the present disclosure adopts a path-based analysis and collection method for SFC service performance and OAM information of the current node, so that in the case of poor device or service performance, the server can obtain it immediately Multi-dimensional OAM information provides conditions for multi-dimensional comprehensive analysis; through weighted calculation and comparison with thresholds, excessive increase in information received by the server is avoided, ensuring that the server processes OAM information with more analytical value as soon as possible.

In addition, the comprehensive evaluation value of business OAM and device OAM is jointly determined by the two types of OAM information. The relevant thresholds, weights, etc. can be set and modified through programming, allowing administrators to make targeted and flexible adjustments based on specific services and network status. Configure various thresholds and weights to improve the matching between evaluation values and business and device characteristics, helping the management plane locate problems more quickly and accurately.

In some embodiments, the parameter acquisition unit 411 may extract the OAM evaluation parameters from a predetermined field in the message header after the network node acquires the NSH message from the SFC upstream node.

The comprehensive evaluation value determination unit 412 can determine the OAM comprehensive evaluation value based on the service OAM information, device OAM information and OAM evaluation parameters. In some embodiments, the service OAM evaluation value and the device OAM evaluation value can be determined separately, and then the two are combined to determine the comprehensive OAM evaluation value. The business OAM evaluation value reflects the deviation of the service status from the normal state; the equipment OAM evaluation value reflects the deviation of the service status from the normal status. In some embodiments, the comprehensive evaluation value determination unit 412 may determine the OAM comprehensive evaluation value based on the above step 104 and in the manner as shown in Figures 2A and 2B.

The data reporting unit 413 can determine the OAM information reporting method to be adopted based on the OAM comprehensive evaluation value, and execute the corresponding reporting method. In some embodiments, the OAM information includes reported service OAM information and device OAM information. In some embodiments, the reporting method includes directly reporting the OAM information to the server by the current network node, or forwarding the OAM information to the destination node through a data packet, and the destination node reports the OAM information to the server.

Such network nodes can comprehensively consider the status of services and equipment, and then select appropriate OAM information reporting methods to reduce the lack of OAM information, improve the accuracy of network operating status analysis, and improve the accuracy and efficiency of problem location.

In some embodiments, the data reporting unit 413 can compare the OAM comprehensive evaluation value with the preset comprehensive threshold, and report the business OAM information and device OAM information to the server when the OAM comprehensive evaluation value is greater than or equal to the preset comprehensive threshold, Therefore, when the comprehensive status of services and equipment is not good, the network node itself can report the business OAM information and equipment OAM information to the server, so that the server can promptly learn about the poor comprehensive status of services and equipment, thereby avoiding The loss of OAM information also improves the accuracy of network operating status analysis and improves the accuracy and efficiency of problem location. In addition, by comparing with the preset comprehensive threshold, it also avoids large-scale reporting of OAM information under normal circumstances, avoids waste of server processing resources, and further improves server processing efficiency.

In some embodiments, the data reporting unit 413 can also transmit device OAM information through data packets when the OAM comprehensive evaluation value is less than the preset comprehensive threshold. In some embodiments, the data reporting unit 413 encapsulates the collected device OAM information in a data packet, and forwards it to the SFP endpoint along with the data packet. In some embodiments, the OAM information forwarded to the SFP along with the data packet also includes service OAM information.

Such network nodes can forward OAM information, including device OAM information, with data packets when the comprehensive status of services and equipment is normal, thereby avoiding reporting OAM information to the server when equipment and services are normal and reducing server costs. reduce the data processing pressure and improve the effective utilization of server computing resources.
