Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1, a schematic step flow diagram illustrating a detection method for a transmission node cluster according to an embodiment of the present invention is shown, which may specifically include the following steps:
The detection method of the transmission node cluster provided by the embodiment of the invention is used for detecting whether each transmission node in the transmission node cluster works normally or not, and comprises a plurality of operations such as detection instruction sending, data updating detection, detection result extraction and the like, wherein the plurality of operations are completed by calling a plurality of functions. The transmission node cluster comprises a plurality of transmission nodes, wherein the transmission nodes are servers with functions of data transmission, data processing and the like.
The embodiment of the invention refers to the client sending the detection instruction to each transmission node of the transmission node cluster as the detection client. Because a plurality of operations corresponding to the detection method are completed by calling a plurality of functions and no sequential association exists between the detection instruction sending operation and the detection result extracting operation, the detection client can call the first function to send a plurality of detection instructions to each transmission node of the transmission node cluster at the same time. The first function called may be various, such as a proc _ open () function. The sent detection instructions can belong to the same detection task or belong to a plurality of detection tasks. The detection instruction may take many forms, such as a numerical calculation instruction, an operating parameter detection instruction, and the like.
The method comprises the steps that a preset array is arranged in a detection client in advance and used for storing detection results fed back by all transmission nodes, and the storage positions of the detection results of different transmission nodes in the preset array are preset. In order to add the detection results fed back by different transmission nodes to the specified storage position in the preset array, when the detection instruction is sent to each transmission node, each detection instruction can carry information indicating the storage position of the detection result in the preset array, namely a file pointer, and the transmission node can extract the file pointer from the received detection instruction and add the detection result to the specified storage position of the preset array according to the file pointer.
The method of the embodiment of the invention can be applied to different scenes, such as a scene of common data transmission and a scene of stream data transmission. When applied to a scenario of streaming data transmission, a transmission node may be a node in a Content Delivery Network (CDN), and a transmission node cluster may include multiple transmission nodes in the Content Delivery Network, for example, multiple transmission nodes located in a certain geographic area may be referred to as a transmission node cluster. The scheduling node in the content distribution network may be used to manage a plurality of transmission nodes in the transmission node cluster, and the scheduling node may call a first function to simultaneously send a detection instruction to each transmission node of the transmission node cluster to detect a working condition of each transmission node.
And 102, calling a second function to detect data updating of the preset array.
The storage positions of different transmission nodes in the preset array may have historical recorded detection results or may be vacant, and after the transmission nodes feed back new detection results, data of the storage positions corresponding to the transmission nodes in the preset array can be changed and updated to the latest detection results.
The embodiment of the invention calls the second function to detect the preset array, particularly calls the second function to detect the data of each storage position in the preset array, and detects whether the updated detection result exists in the preset array. The second function to be called may be various, such as a stream _ select () function.
And 103, calling a third function to extract the updated detection result from the preset array when the updated detection result is detected to exist.
When the second function detects that the updated detection result exists in the preset array, the embodiment of the invention calls the third function to extract the updated detection result from the preset array. Since the detection instruction may be in various forms, the detection result may also be in various forms, such as a numerical calculation result, an operation state parameter detection result, and the like. The called third function may be various, such as a stream _ get _ contents () function.
The preset array is provided with a plurality of storage positions, the second function detects data at the plurality of storage positions, and specifically, the second function can detect the data at the plurality of storage positions in sequence according to the sequence of the plurality of storage positions in the preset array. When the updated detection results exist in each storage position in the preset array, the second function detects all the updated detection results, and at this time, the second function completes the detection of all the detection results corresponding to the detection task, so that the detection of the detection result corresponding to the next detection task can be performed.
And step 104, calling the transmission nodes according to the detection results of all the transmission nodes.
After receiving the node call request, the detection client can select a proper target transmission node to be used by the request end according to the detection result of each transmission node in the transmission node cluster, and the detection result provides a basis for node allocation.
The selection condition of the target transmission node may be various, for example, when the detection result is a numerical calculation result, whether the transmission node normally works may be determined by identifying the numerical value, and after it is determined that the transmission node normally works, the transmission node which normally works and is close to the request end may be selected as the target transmission node; when the detection result is the operation state parameter of the transmission node, such as the CPU utilization rate, the content occupancy rate, and the like, the transmission node with a lighter load and a closer distance to the request end may be selected as the target transmission node, thereby ensuring load balance of each transmission node in the cluster.
When the method is applied to a scene of streaming data transmission, the scheduling node in the content distribution network can supervise and distribute a plurality of transmission nodes in the transmission node cluster by executing the method, and when the scheduling node determines that a certain transmission node works abnormally according to the detection result, the scheduling node can send a node abnormity notice so as to repair the transmission node as soon as possible. Meanwhile, the scheduling node can reallocate a proper target transmission node for the node request terminal according to the detection result.
Compared with the execution processes of sending one detection instruction, receiving a corresponding detection result, sending the next detection instruction and receiving the corresponding detection result in the background technology, the method can greatly shorten the time of detection operation, shorten the waiting time of the detection result and improve the detection execution efficiency.
In this embodiment of the present invention, preferably, before the invoking of the transmission node is performed according to the detection results of all the transmission nodes, the method further includes: receiving a calling request of a first client to a transmission node;
the detection result includes at least one operation state parameter of the transmission node, and the calling of the transmission node according to the detection results of all the transmission nodes includes: and selecting a target transmission node with the operating state parameter meeting the set condition, and feeding back the target transmission node to the first client.
The detection client is responsible for detecting a plurality of transmission nodes in the transmission node cluster and also responsible for the distribution work of the plurality of transmission nodes. After receiving the node call request sent by the first client, the detection client can determine the operating conditions of each transmission node according to the detection result of each transmission node, so that a proper target transmission node is allocated to the first client, for example, a transmission node with a short distance and a light load is allocated.
The detection result may include various contents, and when the detection result includes at least one operation state parameter of the transmission node, such as a CPU utilization rate, a memory occupancy rate, and the like, the detection client may select a target transmission node whose operation state parameter satisfies a set condition, and feed back the selected target transmission node to the first client.
Different running state parameters can correspond to different setting conditions, for example, when the running state parameters are the CPU utilization rate, the setting conditions can be that the CPU utilization rate is less than a%, wherein a is a positive number; when the operation state parameter is the memory occupancy rate, the setting condition may be that the memory occupancy rate is less than b%, where b is a positive number.
In a scenario of streaming data transmission, the detection client may be a scheduling node, the first client may be a streaming data client, and when the streaming data client pushes streaming data to the network or pulls the streaming data from the network, a call request to the transmission node is sent to the scheduling node, and accordingly the scheduling node receives the call request of the streaming data client to the transmission node. The scheduling node may select a transmission node whose operating state parameter meets the set condition as a target transmission node, and feed back the target transmission node to the streaming data client for use.
The embodiment of the invention allocates the target transmission nodes according to the running state parameters of the transmission nodes, can ensure that the target transmission nodes allocated to the first client side all work normally, can also ensure the load balance of a plurality of transmission nodes in the transmission node cluster, and avoids the phenomenon of overweight load of the transmission nodes.
According to the embodiment of the invention, the first function is called to send the detection instruction, the second function is called to detect data updating, the third function is called to extract the updated detection result, different functions are called to execute different operations, and the operations are not sequentially associated, so that the embodiment of the invention can simultaneously send a plurality of detection instructions to each transmission node, and the plurality of detection instructions can be executed by different transmission nodes in a short time, thereby shortening the sending time of the plurality of detection instructions and the receiving time of the plurality of detection results, and improving the execution efficiency of the detection operation.
Referring to fig. 2, a schematic step flow diagram illustrating a detection method for a transmission node cluster according to a second embodiment of the present invention is shown, which may specifically include the following steps:
The detection method comprises a plurality of operations such as detection instruction sending, data updating detection, detection result extraction and the like, and the plurality of operations are executed by calling a plurality of functions. The embodiment of the invention refers to the client sending the detection instruction to each transmission node of the transmission node cluster as the detection client.
To improve the detection accuracy, multiple detection tasks may be used to detect each transmission node. Specifically, the first function may be called to sequentially send the detection instructions corresponding to the plurality of detection tasks to each transmission node of the transmission node cluster. Because the carrying capacity of each transmission node to the detection result is different, the detection instructions corresponding to a plurality of detection tasks can be sent to each transmission node according to different modes. When the carrying capacity of the transmission node is weak, the sending mode of the detection instruction corresponding to the multiple detection tasks may be: and calling the first function to execute a detection task, and calling the first function to execute the next detection task after the detection results of all transmission nodes to the detection task are extracted. For example, after 100 detection instructions corresponding to the detection task 1 are sent and 100 detection results fed back by 100 transmission nodes are extracted, 100 detection instructions corresponding to the detection task 2 are sent, and the sending of the detection instructions corresponding to the multiple detection tasks is completed according to the above method.
When the carrying capacity of the transmission node is strong, the sending mode of the detection instruction corresponding to the multiple detection tasks may be: after a first function is called to send a detection instruction corresponding to one detection task to each transmission node of a transmission node cluster, a plurality of detection instructions corresponding to the next detection task are directly called to send the first function. For example, after 100 detection commands corresponding to the detection task 1 are transmitted, 100 detection commands corresponding to the detection task 2 are directly transmitted, and the detection commands corresponding to the plurality of detection tasks are transmitted according to the above-described method.
For the sending mode of the detection instructions corresponding to the multiple detection tasks when the carrying capacity of the transmission node is weak, the detection operation of the next detection task can be executed only after the execution of the current detection task is finished, and the sending time of the detection instructions corresponding to two adjacent detection tasks has a processing time interval.
In order to control the sending time of the detection instructions corresponding to the plurality of detection tasks when the sending mode is executed, in the embodiment of the present invention, before the first function is called to execute the next detection task, the recorded historical processing time may be searched for the next detection task to be executed, and the processing time interval between the one detection task and the next detection task may be set according to the searched historical processing time of the next detection task. After the execution of the detection task is started, the first function can be called to execute the next detection task according to the set processing time interval.
For example, the historical processing time of the first detection task is a seconds, the processing time of the second detection task is B seconds, the first detection task is executed first, the second detection task is executed later, the time a seconds is taken as the processing time interval between the first detection task and the second detection task, after the first detection task is started to be executed, namely the first function is called to send the detection instruction to each transmission node of the transmission node cluster, after a seconds, the second detection task is started to be executed, and the first function is called to send the detection instruction to each transmission node of the transmission node cluster.
In order to execute the above steps, the processing time interval of the two detection tasks is set according to the historical processing time of the detection task, and the embodiment of the invention can record the historical processing time of the detection task after receiving the detection results of all transmission nodes corresponding to one detection task, so as to extract the historical use time from the local record. The sending time of each detection instruction and the receiving time of the detection result corresponding to the detection instruction may be recorded, and the difference between the receiving time of the detection result and the sending time of the detection instruction may be calculated, taking the maximum time difference as the historical processing time of the detection task.
When the detection client sends the detection instructions corresponding to the multiple detection tasks, the detection client may determine the historical processing time of the currently executed current detection task according to the correspondence between the locally recorded detection task and the historical processing time after sending the detection instruction corresponding to the current detection task to each transmission node, and send the detection instruction corresponding to the next detection task after sending the historical processing time of the current detection task.
If the currently executed detection task is a new task and the detection client does not locally record the historical processing time of the task, the embodiment of the invention can use the average value of the historical processing time of other detection tasks as the historical processing time for the detection task which does not find the historical processing time. For example, if the detection client locally records that the historical processing time of the detection task 1 is 0.10s, the historical processing time of the detection task 2 is 0.12s, and the historical processing time of the detection task 3 is 0.4s, the historical processing time calculated by the new detection task is 0.12 s.
The embodiment of the invention can use the same interface to send the detection instruction and receive the detection result, and can also use different interfaces to send the detection instruction and receive the detection result. In this step, a first function may be called by a first interface to simultaneously send a plurality of detection instructions to each transmission node of the transmission node cluster, and the transmission node may send a detection result to the preset array through a second interface, where the first interface and the second interface may be the same or different. When the second interface is different from the first interface, the number of the second interfaces may be one or more, and the number of the second interfaces may be set according to the actual situation.
When the detection result that the interface received in a certain period is too much, the phenomenon that the detection result stays at the interface can appear, and the stay phenomenon can prolong the time that the detection result passes through the interface, and reduces the speed that the detection result is fed back to the detection client. In order to prevent the number of the detection results transmitted to the second interface from exceeding the number of the bearers of the interface and ensure that each detection result passes through the second interface in a short time, the embodiment of the invention can detect the current number of the bearers of the second interface on the detection results, calculate the remaining number of the bearers of the second interface on the detection results and then call the first function through the first interface to simultaneously send the detection instructions of the remaining number of the bearers to each transmission node of the transmission node cluster before calling the first function through the first interface to simultaneously send the detection instructions of the detection results to each transmission node of the transmission node cluster.
And step 204, identifying whether the transmission node normally operates according to the detection result.
The detection result may include a variety of content that may indicate the operational condition of the transmitting node. And after the detection client receives the detection result, whether the transmission node normally operates can be identified according to the detection result.
Since the detection result may include various contents, there are various ways of identifying whether the transmission node operates normally. For example, when the detection result is a numerical calculation result, that is, a numerical value, the client performing the node detection may determine whether the transmission node normally operates according to the numerical value, where if the detection instruction is "calculate 1+ 1", if the received detection result is "2", it is determined that the transmission node normally operates, and otherwise, it is determined that the transmission node abnormally operates. When the detection result is the operation state parameter of the transmission node, such as the CPU utilization rate, the memory occupancy rate, and the like, the detection client may determine whether the operation state parameter of the transmission node satisfies a set condition, and if yes, determine that the transmission node is working normally, otherwise, determine that the transmission node is working abnormally.
