Detailed Description
The technical scheme of the present disclosure is described in further detail below through the accompanying drawings and examples.
In the related art, the general state of network service operation can only be inferred indirectly and roughly based on the first type of OAM information uploaded under the specified conditions, which is contrary to the purpose of implementing the real-time collection of OAM information using the telemethod. The server cannot monitor the operation conditions of both the equipment and the service path nodes in real time at the same time, so that the follow-up network operation state analysis is single and one-sided, and the problem is difficult to accurately position.
Aiming at the problems, the disclosure provides an OAM information processing method, which improves timeliness and comprehensiveness of OAM information collection, and further can solve the problems of more timely and accurate positioning.
A flowchart of some embodiments of an OAM information processing method of the present disclosure is shown in fig. 1.
In step 102, the network node obtains OAM evaluation parameters. In some embodiments, the OAM evaluation parameters may be carried by the header of the NSH message, communicated between the nodes of the SFC. In some embodiments, the network node may extract OAM evaluation parameters from a predetermined field of its header after acquiring the NSH message.
In some embodiments, the OAM evaluation parameters include a threshold value of the service SLA, a weight assignment value of the service SLA, an OAM weight assignment value of the device, and a preset integration threshold value.
In some embodiments, the SFC NSH header may be extended, where the source node of the SFC sets the following information in the SFC NSH header:
the type of service SLA;
threshold of service SLA;
the weight distribution value of the service SLA;
OAM weight allocation values of the equipment;
presetting an integrated threshold.
When the SFC generates the NSH packet, the packet header carries the OAM evaluation parameters, and in some embodiments, the payload field of the NSH packet carries the user data, so that the OAM evaluation parameters can be transmitted between nodes of the SFC along with the user data.
In some embodiments, the OAM evaluation parameters carried in the SFC NSH header are programmable parameters, and the user may set and generate configuration information, set or modify the OAM evaluation parameters corresponding to the type of each service SLA, and the threshold value and the weight allocation value corresponding to the different types of service SLAs may be different, so as to improve the flexibility and the controllable degree of reporting OAM information.
In step 104, the network node determines an OAM integrated evaluation value from the service OAM information, the device OAM information, and the OAM evaluation parameters. In some embodiments, a service OAM evaluation value and a device OAM evaluation value may be determined separately, and then combined to determine an OAM integrated evaluation value. The service OAM evaluation value reflects the deviation condition of the service state relative to the normal state; the equipment OAM evaluation value reflects the deviation of the traffic state from the normal state.
In some embodiments, the network node also collects its own device OAM information. In some embodiments, the device OAM information may include multiple dimensions such as CPU usage, memory occupancy, packet loss per second, throughput, power dissipation, etc.
In some embodiments, the service OAM evaluation value and the equipment OAM evaluation value may be multiplied to form an OAM integrated evaluation value, so that considering that the evaluation dimensions of the OAM of the service and the equipment are different, the multiplication result of the two is taken as the OAM integrated evaluation value, which can reduce the excessive influence caused by one of the two, and improve the accuracy of the evaluation value reflecting the status of the service and the equipment.
In step 106, the network node determines the reporting mode of the adopted OAM information according to the OAM integrated evaluation value, and executes the corresponding reporting mode. In some embodiments, the OAM information includes reporting service OAM information and device OAM information. In some embodiments, the reporting mode includes reporting the OAM information directly to the server by the current network node or forwarding the OAM information through a data packet to the destination node, where the OAM information is reported to the server by the destination node.
Based on the modes in the embodiment shown above, the states of the service and the equipment can be comprehensively considered, and then a proper OAM information reporting mode is selected, so that the loss of OAM information is reduced, the accuracy of network operation state analysis is improved, and the accuracy and efficiency of problem positioning are improved.
In some embodiments, the operations in step 106 above may include: and comparing the OAM comprehensive evaluation value with a preset comprehensive threshold value. And under the condition that the OAM comprehensive evaluation value is larger than or equal to a preset comprehensive threshold value, the current node directly reports the OAM information to the server.
Based on the mode in the embodiment shown above, the network node can report the service OAM information and the equipment OAM information to the server by the network node under the condition that the comprehensive state of the service and the equipment is not good, so that the server can timely acquire the condition that the comprehensive state of the service and the equipment is not good, the loss of the OAM information is avoided, the accuracy of analysis of the network running state is also improved, and the accuracy and the efficiency of problem positioning are improved. In addition, by comparing the OAM information with the preset comprehensive threshold value, a large amount of OAM information is prevented from being reported under normal conditions, waste of server processing resources is avoided, and the processing efficiency of the server is further improved.
In some embodiments, the step 106 may further include: and under the condition that the OAM comprehensive evaluation value is smaller than a preset comprehensive threshold value, determining OAM information of the data message transmission equipment. 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 ) along with the data packet. In some embodiments, the OAM information forwarded with the data packet to the SFP may also include traffic OAM information.
Based on the mode in the embodiment, OAM information including the OAM information of the equipment can be forwarded along with the data message under the condition that the comprehensive state of the service and the equipment is normal, so that the OAM information is prevented from being reported to the server under the condition that the service and the equipment are normal, the data processing pressure of the server is reduced, and the effective utilization of the operation resources of the server is improved.
In some embodiments, in step 104, a flowchart of some embodiments of obtaining the service OAM estimated value is shown in fig. 2A.
In step 211, a service OAM ratio value is determined from the service OAM information and a threshold value of the service SLA.
In some embodiments, the service OAM ratio value a' may be obtained by dividing the service OAM information a by the threshold value b of the corresponding service SLA. In some embodiments, the current traffic state is better if a '>1, and worse if a' < 1.
In some embodiments, the service OAM information may be represented in multiple dimensions, including a 1 、……a p P is the dimension number of the service OAM information and is a positive integer greater than 1. Threshold b for each dimension corresponding to a service SLA 1 、……b p The OAM ratio value a of each dimension is obtained through calculation 1 ’、……a p ' wherein a 1 ’＝a 1 /b 1 ……a p ’＝a p /b p 。
In step 212, a service OAM weighted ratio value a "is determined from the service OAM ratio value a' and the weight assignment value k of the service SLA.
In some embodiments, the weight assignment value of the service SLA includes a weight corresponding to each dimension, e.g., k 1 、……k p Further multiplying the business OAM ratio value of each dimension with the corresponding weight to obtain an OAM weighted ratio value a of the corresponding dimension 1 ”＝k 1 *a 1 ’……a p ”＝k p *a p '. In some embodiments, the high importance dimension corresponds to a higher weight than the low importance dimension.
In step 213, a service OAM evaluation value a is determined from the service OAM weighing ratio value for each dimension.
In some embodiments, the OAM weighted ratio values of the services in each dimension may be multiplied to obtain the service OAM evaluation value a, e.g., a=a 1 ”*……a p ”。
Based on the manner in the above embodiment, the service OAM can be first subjected to dimension analysis to obtain the service status condition of each dimension, and then a weighted ratio value is obtained according to the importance of each dimension, and then the weighted ratio value of each dimension is synthesized to determine a service OAM evaluation value, where the OAM evaluation value can reflect the status of the service OAM from each dimension, and then is used as a data basis for judging whether to report the service OAM directly or not, thereby improving the accuracy of the reporting timer.
In some embodiments, in the above step 104, a flowchart of some embodiments of obtaining the equipment OAM evaluation value is shown in fig. 2B.
In step 221, an OAM weighted ratio value C of the device is determined from the device OAM information C and an OAM weight assignment value r of the device.
In some embodiments, the device OAM information c may be divided by the corresponding device threshold d to obtain a device OAM ratio value c ', and further, the device OAM weighted ratio value c ' is determined according to the device OAM ratio value c ' and the OAM weight allocation value r of the device.
In some embodiments, if c '>1, the current device state is better, and if c' <1, the current device state is worse.
In some embodiments, the device OAM information may be represented in multiple dimensions, including c 1 、……c q Q is the dimension number of the OAM information of the equipment and is a positive integer greater than 1. Each dimension corresponds to a device threshold d 1 、……d q Device OAM ratio value c of each dimension is obtained through calculation 1 ’、……c q ' wherein c 1 ’＝c 1 /d 1 ……c q ’＝c q /d q 。
In some embodiments, the OAM weight allocation value of the device includes a weight corresponding to each dimension, e.g., r 1 、……r q Further multiplying the equipment OAM ratio value of each dimension by the corresponding weight to obtain an equipment OAM weighted ratio value c of the corresponding dimension 1 ”＝r 1 *c 1 ’……c q ”＝r q *c q '. In some embodiments, the corresponding weights for the high importance dimensions are higher than the corresponding weights for the low importance dimensions.
In step 222, a device OAM evaluation value is determined from OAM weighted ratio values for the devices of each dimension. In some embodiments, the device OAM weighted ratio values of the respective dimensions may be multiplied to obtain a device OAM evaluation value C, e.g., c=c 1 ”*……c q ”。
In some embodiments, based on the table shown in fig. 2A, 2B, OAM combined evaluation value=a×c.
Based on the mode in the above embodiment, the device OAM can be subjected to dimension analysis to obtain the device state condition of each dimension, and then the device OAM evaluation value is determined by integrating the device state condition of each dimension and the importance thereof, and the OAM evaluation value can reflect the state of each dimension of the device, and then is used as a data basis for judging whether to report the device OAM directly or not, so that the accuracy of reporting the device OAM determination is improved.
A schematic diagram of some embodiments of an OAM information processing method of the present disclosure is shown in fig. 3, and an example is a node SF (Service Function) entity including two VNFs (Virtual Network Function) between a source node and a destination device of an SFC.
When the SFC source node 31 generates an NSH message based on data from the source end user, a header of the NSH message sent to the SF1 is expanded, and OAM evaluation parameters such as a type of a service SLA are carried; in addition, the payload portion of the message carries user data and classified OAM information. When the message reaches the intermediate node SF1 of the SFC, the node determines an OAM integrated evaluation value and compares it with a predetermined integrated threshold.
If the SF1 determines that the OAM comprehensive evaluation value is greater than or equal to the preset comprehensive threshold value, the OAM message is utilized to carry the equipment OAM information and the service OAM information of the SF1 through the payload part, and the equipment OAM information and the service OAM information are reported to the server 30.
If the SF1 determines that the OAM synthesis evaluation value is less than the predetermined synthesis threshold, the OAM information of the device is carried by an NSH message and sent to a next node on the SFC, such as SF2.
Assuming that SF2 determines that the OAM synthesis evaluation value is < a predetermined synthesis threshold after determining the OAM synthesis evaluation value, equipment OAM information of SF2 is added to the payload portion of the NSH message. When the end point device 34 (which may be a router) of the SFC receives the NSH message, the OAM information of each device in the payload and the end-to-end OAM information of the SFC service are parsed, and the OAM information is carried by the payload portion of the OAM message, and reported to the server 30.
In the related art, only the performance of the equipment is analyzed and collected by adopting a channel associated method, and the OAM information of the service is uploaded to the server only when the data message reaches the end point; the equipment OAM information collected at the intermediate node has single dimension, and no service OAM information can be comprehensively analyzed. Compared with the related technology, the mode in the embodiment of the disclosure has the advantages that the SFC service performance and the OAM information of the current node are both analyzed and collected by the following path, so that the server can acquire multidimensional OAM information at the first time under the condition of poor equipment or service performance, and conditions are provided for multidimensional comprehensive analysis; by means of weighted calculation and comparison with a threshold value, excessive increase of information received by a server is avoided, and the first time of the server is ensured to process OAM information with more analysis value.
In addition, the comprehensive evaluation values of the service OAM and the equipment OAM are determined by the two types of OAM information together, and related thresholds, weights and the like can be set and modified through programming, so that an administrator can flexibly configure various thresholds and weights in a targeted manner according to specific service and network states, the matching degree of the evaluation values and the characteristics of the service and the equipment is improved, and the management plane is helped to locate the problem more quickly and accurately.
A schematic diagram of some embodiments of a network node 41 of the present disclosure is shown in fig. 4.
The parameter acquisition unit 411 can acquire OAM evaluation parameters. In some embodiments, the OAM evaluation parameters may be carried by the header of the NSH message, communicated between the nodes of the SFC. In some embodiments, the parameter obtaining unit 411 may extract OAM evaluation parameters from a predetermined field of the header after the network node obtains the NSH packet from the SFC upstream node.
The comprehensive evaluation value determination unit 412 can determine an OAM comprehensive evaluation value from the service OAM information, the device OAM information, and the OAM evaluation parameter. In some embodiments, a service OAM evaluation value and a device OAM evaluation value may be determined separately, and then combined to determine an OAM integrated evaluation value. The service OAM evaluation value reflects the deviation condition of the service state relative to the normal state; the equipment OAM evaluation value reflects the deviation of the traffic state from the normal state. In some embodiments, the integrated evaluation value determination unit 412 may determine the OAM integrated evaluation value based on the above-described step 104 and the manner as in fig. 2A, 2B.
The data reporting unit 413 can determine the reporting mode of the adopted OAM information according to the OAM integrated evaluation value, and execute the corresponding reporting mode. In some embodiments, the OAM information includes reporting service OAM information and device OAM information. In some embodiments, the reporting mode includes reporting the OAM information directly to the server by the current network node or forwarding the OAM information through a data packet to the destination node, where the OAM information is reported to the server by the destination node.
The network node can comprehensively consider the states of the service and the equipment, further select a proper OAM information reporting mode, reduce the loss of OAM information, improve the accuracy of network operation state analysis and improve the accuracy and efficiency of problem positioning.
In some embodiments, the data reporting unit 413 can compare the OAM integrated evaluation value with a preset integrated threshold, and report the service OAM information and the equipment OAM information to the server when the OAM integrated evaluation value is greater than or equal to the preset integrated threshold, so that the network node itself can report the service OAM information and the equipment OAM information to the server when the integrated status of the service and the equipment is not good, so that the server can timely learn the situation that the integrated status of the service and the equipment is not good, thereby avoiding loss of OAM information, improving accuracy of analysis of network operation status, and improving accuracy and efficiency of problem location. In addition, by comparing the OAM information with the preset comprehensive threshold value, a large amount of OAM information is prevented from being reported under normal conditions, waste of server processing resources is avoided, and the processing efficiency of the server is further improved.
In some embodiments, the data reporting unit 413 is further capable of transmitting the equipment OAM information through the data packet if the OAM integrated evaluation value is less than a preset integrated threshold value. In some embodiments, the data reporting unit 413 encapsulates the collected device OAM information in a data packet, and forwards the data packet to the end point of the SFP. In some embodiments, the OAM information forwarded with the data packet to the SFP also includes service OAM information.
The network node can forward the OAM information including the OAM information of the equipment along with the data message under the condition that the comprehensive states of the service and the equipment are normal, so that the OAM information is prevented from being reported to the server under the condition that the service and the equipment are normal, the data processing pressure of the server is reduced, and the effective utilization of the operation resources of the server is improved.
