Description
Technical Field
The present invention relates to the field of data transmission technologies, and in particular, to a method and an apparatus for detecting a transmission path.
Background
An application acceleration network is a network deployed between a sending end and a receiving end for accelerating data transmission. When the sending end transmits data to a destination address (namely, a receiving end address) through the application acceleration network, the sending end can send the data to an entrance acceleration node of the application acceleration network, and the entrance acceleration node can transmit the data to the receiving end through an optimal transmission path reaching the receiving end in the application acceleration network.
In the specific processing, each time the entry acceleration node receives data traffic directed to the destination address, a network detection task for the destination address may be newly added, and corresponding task parameters (including duration, detection interval, and the like) are configured, so as to obtain network states (including transmission delay, transmission packet loss rate, acceleration node load, path bandwidth utilization rate, and the like) of multiple transmission paths from the entry acceleration node to the destination address, thereby determining an optimal transmission path for subsequent data transmission. In the network detection process, if the data traffic pointing to the destination address is received again, the entry acceleration node can reset the duration of the network detection task and continue to perform network detection according to the original detection interval.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a method for detecting a transmission path, wherein an execution main body of the method can be an entrance acceleration node of an application acceleration network, a network framework of the application acceleration network can be shown in figure 1, the application acceleration network can be composed of a plurality of acceleration nodes, and the acceleration nodes can be mainly divided into an entrance acceleration node, a middle acceleration node and an exit acceleration node.
The entry acceleration node may be configured to receive a data flow sent by the sending end to the receiving end, transmit the data flow to a last-hop acceleration node (i.e., an exit acceleration node) connected to the receiving end through one or more stages of intermediate acceleration nodes (no intermediate acceleration node may exist in a transmission path) in the application acceleration network according to a preset transmission path, and send the data flow to the receiving end by the exit acceleration node.
The entrance acceleration node can also detect all transmission paths reaching a receiving end in the application acceleration network while transmitting the data traffic, and select or modify a preset transmission path according to a detection result so as to ensure that the preset transmission path is always the path with the optimal transmission quality.
The entry acceleration node may include a processor, a memory, and a transceiver, where the processor may be configured to perform a process of performing network probing on the transmission path in the following process, the memory may be configured to store data required in the process and generated data, such as the number of times of receiving data traffic, task parameters of a network probing task, and the like, and the transceiver may be configured to receive and transmit related data in the process, such as receiving data traffic, transmitting a probe message, and the like. It is understood that one acceleration node may implement the functions of an ingress acceleration node, an intermediate acceleration node, or an egress acceleration node, respectively, during different data transmission processes.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
In implementation, when the sending end sends data traffic to the receiving end through the application acceleration network, the entry acceleration node connected to the sending end in the application acceleration network may receive the data traffic pointing to the receiving end, and determine the network address (i.e., the destination address) of the receiving end based on information carried in the data traffic, and then the entry acceleration node may locally search a preset transmission path to the destination address, and may further transmit the data traffic to the receiving end through the transmission path. Meanwhile, when determining the destination address based on the data traffic, the entry acceleration node may also determine whether a network detection task for the destination address already exists locally.
Specifically, the network probing task may include probing network transmission performance such as a network transmission rate, a packet loss rate, and a bandwidth utilization rate.
And step 202, if the network probe task exists, adding one to the recorded receiving times of the data traffic pointing to the destination address, otherwise, creating the network probe task.
In an implementation, the entry acceleration node may, after creating a network probe task for a certain destination address, temporarily not immediately execute the network probe task, but first record the number of times of receiving data traffic directed to the destination address. Therefore, if the network detection task aiming at the destination address exists locally, the entrance acceleration node can add one to the recorded receiving times of the data traffic pointing to the destination address; if the network detection task aiming at the destination address does not exist locally, the network detection task aiming at the destination address can be established, corresponding task parameters such as detection interval, duration and the like are set, and meanwhile, the receiving times of the data traffic pointing to the destination address can be recorded.
And step 203, when the receiving times are larger than a preset hot address threshold value, executing the network detection task and resetting the duration of the network detection task.
In implementation, after the entry acceleration node modifies the number of times of receiving the data traffic directed to the destination address each time, the entry acceleration node may determine a size relationship between the number of times of receiving and a preset hot address threshold. When the receiving times are greater than a preset hot address threshold, it can be stated that the heat of the destination address reaches a degree worth detecting, the network probing task can be executed, and the duration of the network probing task is reset, where the duration of the network probing task refers to a duration that can exist continuously after the network probing task is created, that is, a duration from creation to logout, and during the duration, the execution of the network probing task can be triggered based on the judgment of the hot address threshold, that is, the network probing task is in a waiting execution state after being created, if the network probing task is triggered within the duration, the probing is executed, and if the network probing task is not triggered within the duration, the probing will not be executed.
It should be noted that, after triggering the execution of the network probing task, the ingress acceleration node will continue to execute the network probing task based on the probing interval that the network probing task already has, during which, when the ingress acceleration node receives the data traffic directed to the destination address, the duration of the network probing task may be reset.
For example, the entry acceleration node creates a network probe task pointing to the destination address at 10 min 00 s, and sets the duration of the network probe task to be 90 s and the probe interval to be 30 s, that is, normally, the network probe task will be logged off at 11 min 30 s.
At 10 minutes and 20 seconds, the entry acceleration node determines that the number of times of receiving the data traffic directed to the destination address is greater than a preset hot address threshold, immediately triggers the execution of the network probing task, that is, executes the network probing task once at 10 minutes and 20 seconds, wherein the time for executing the network probing task once is about 3 seconds, and executes the network probing task based on the probing interval of 30 seconds within the duration of the network probing task, that is, before 11 minutes and 30 seconds, that is, executes the network probing task once at two time points of 10 minutes and 50 seconds and 11 minutes and 20 seconds, respectively.
Before 11 minutes and 30 seconds, each time data traffic directed to the destination address is received, the ingress acceleration node may reset the duration of the network probing task, where the resetting is specifically to reset the duration of the network probing task by using the time point of receiving the data traffic directed to the destination address as a starting point and by using 90 seconds as an extension length, that is, if the ingress acceleration node receives the data traffic directed to the destination address at 10 minutes and 50 seconds, the duration of the network probing task is extended by 90 seconds, that is, the network probing task is to be cancelled at 12 minutes and 20 seconds.
Optionally, in the process of executing the network probing task, the probing interval of the network probing task may be adjusted in real time according to the heat of the destination address, and accordingly, the following processing may be performed after step 203: counting the receiving times of data flow pointing to a destination address within a single detection interval duration of a network detection task; and adjusting the detection interval of the network detection task according to the receiving times of the data flow and a preset interval adjustment threshold value.
In implementation, after the network probe task is executed, the entry acceleration node may trigger the execution of the network probe task according to an initial probe interval, and may count the number of times of receiving the data traffic directed to the destination address in each probe interval duration of the network probe task by using the probe interval as a unit. Then, when each detection interval is finished, the detection interval of the network detection task is adjusted according to the counted receiving times of the data traffic and a preset interval adjustment threshold, the network detection task is executed according to the adjusted detection interval, the receiving times are counted according to the adjusted detection interval duration, and then the detection interval is adjusted when the adjusted detection interval is finished. Therefore, the heat degree of the destination address can be judged according to the receiving times of the data flow, so that different detection intervals can be flexibly set for the destination addresses with different heat degrees. Specifically, for a destination address with high heat, the detection frequency can be increased by shortening the detection interval, so that the real-time performance of the detection result can be ensured, and for a destination address with low heat, the detection frequency can be reduced by enlarging the detection interval, so that the resource for network detection is saved.
Alternatively, the above mechanism for adjusting the sounding interval may be various, and two possible mechanisms are given as follows:
one is as follows: if the receiving times are smaller than the interval adjustment threshold, expanding the detection interval of the network detection task based on the value of the receiving times; if the receiving times are equal to the interval adjustment threshold, keeping the detection interval of the network detection task unchanged; and if the receiving times are larger than the interval adjusting threshold, reducing the detection interval of the network detection task based on the numerical value of the receiving times.
In implementation, in the process of adjusting the detection interval by the ingress acceleration node at the end of each detection interval, it may be determined that the number of times of receiving the data traffic directed to the destination address within the duration of the current detection interval is equal to the preset interval adjustment threshold. If the receiving times are smaller than the interval adjustment threshold, the detection interval of the network detection task can be expanded based on the numerical value of the receiving times; if the receiving times are equal to the interval adjustment threshold, the detection interval of the network detection task can be kept unchanged; and if the receiving times are larger than the interval adjusting threshold, reducing the detection interval of the network detection task based on the numerical value of the receiving times. For example, if the interval adjustment threshold is 5, the sounding interval is 30 seconds, and the number of receptions is 4, the sounding interval may be increased by (5-4)/5 times, and if the number of receptions is 6, the sounding interval may be decreased by (6-5)/5 times. The above description only exemplarily shows one possible scheme for adjusting the sounding interval, and the present embodiment does not limit a specific scheme for adjusting the sounding interval based on the value of the number of times of reception.
The second step is as follows: if the receiving times are smaller than the interval adjustment threshold, expanding the detection interval of the network detection task based on the value of the receiving times; and if the receiving times are not less than the interval adjustment threshold, adjusting the detection interval of the network detection task to an initial value.
In implementation, in the process of adjusting the detection interval by the ingress acceleration node at the end of each detection interval, it may be determined that the number of times of receiving the data traffic directed to the destination address within the duration of the current detection interval is equal to the preset interval adjustment threshold. If the receiving times are smaller than the interval adjustment threshold, expanding the detection interval of the network detection task based on the value of the receiving times; and if the receiving times are not less than the interval adjustment threshold, adjusting the detection interval of the network detection task to an initial value.
It is worth mentioning that, in order to avoid the detection interval of the network detection task from being infinitely increased or infinitely decreased, the detection interval is ensured to be within a controllable range, the detection interval of the network detection task may be set to a maximum value and a minimum value, that is, no matter what value the receiving times is, the adjusted detection interval is not greater than the maximum value or less than the minimum value, if the adjusted detection interval is greater than the maximum value, the value is the maximum value, and similarly, if the adjusted detection interval is less than the minimum value, the value is the minimum value.
Optionally, in the process of adjusting the detection interval, the interval adjustment threshold may be adjusted according to the counted receiving times, and the corresponding processing may be as follows: and at the starting moment of each detection interval of the network detection task, adjusting the interval adjustment threshold according to the receiving times of the data traffic pointing to the destination address counted in the plurality of historical detection interval durations.
In implementation, in the process of executing the network probing task, the entry acceleration node may obtain, at the start time of each probing interval of the network probing task, the number of times of receiving data traffic pointing to the destination address counted within a plurality of historical probing interval durations, and then adjust the interval adjustment threshold according to the number of times of receiving the data traffic.
Specifically, different historical detection intervals corresponding to different addition weights can be set, a difference obtained by subtracting the receiving times from the interval adjustment threshold in each historical detection interval is calculated, and the difference of each historical detection interval is multiplied by the addition weight and then accumulated with the default interval adjustment threshold, so that a new interval adjustment threshold can be obtained. If 3 historical detection intervals are taken, the corresponding addition weights are 0.1, 0.3 and 0.5 in sequence, the corresponding interval adjustment thresholds are 3, 4 and 3 in sequence, the corresponding receiving times are 2, 5 and 4 in sequence, the default interval adjustment threshold is 3, and then the adjusted interval adjustment threshold is 2. It is easy to understand that the receiving times of the historical statistics are combined, the cold and hot degree of the destination address is measured integrally and is embodied in the form of interval adjustment threshold, so that the situation that the detection interval is too large and the entrance acceleration node cannot update the optimal transmission path in time due to the sudden reduction of data flow in a certain detection interval can be avoided.
Optionally, when a preset optimal transmission path fails, network detection may be performed immediately, and corresponding processing may be as follows: and if the data transmission state between the local address and the destination address is detected to be abnormal, immediately triggering network detection, and resetting the duration and the detection interval of the network detection task.
In implementation, the ingress network node may continuously detect a data transmission state between the local and the destination address, that is, detect a network state of a transmission path that is preset locally and reaches the destination address. When the data transmission state is detected to be abnormal, one-time network detection can be immediately triggered, and the duration and the detection interval of the network detection task are reset, so that an available transmission path can be timely reselected, and the problem that data flow cannot be transmitted for a long time due to the fault of the optimal transmission path is avoided. It should be noted that the data transmission status referred to herein is abnormal, including the case where the transmission path to the destination address is not preset locally.
Alternatively, if the network probing task for the destination address is not executed for a long time, the hot address threshold may be appropriately reduced, and the corresponding processing may be as follows: and adjusting the hot address threshold according to the time difference between the current time and the execution time of the last network detection.
In implementation, the entry acceleration node may start timing after each network probe is executed, and after a certain time period elapses, the hot address threshold may be adjusted according to a time difference between a current time and an execution time of a last network probe. For example, if the time difference between the current time and the execution time of the last network probe is 5min, the hot address threshold may be decreased by 1, and if the time difference is 7min, the hot address threshold may be decreased by 1 again. Therefore, under the condition that the data flow is not received for a long time, the preset transmission path can be ensured to have better data transmission quality to a certain extent, and the situation that the transmission path cannot be replaced in time when the data transmission quality of the preset transmission path greatly slides down due to the fact that the thermal address threshold is set to be too high and the network detection task is not executed for a long time is avoided.
In the embodiment of the invention, when data traffic pointing to a destination address is received, whether a network detection task aiming at the destination address exists locally is judged; if yes, adding one to the recorded receiving times of the data flow pointing to the destination address, otherwise, creating a network detection task; and when the receiving times are more than the preset hot address threshold value, executing the network detection task and resetting the duration of the network detection task. Therefore, the heat degree of the destination address can be judged and identified by counting the data transmission times of the destination address, and the detection frequency of the network detection task for the destination address is adjusted based on the heat degree, so that the detection frequency of the destination address with low heat degree can be reduced, the detection frequency of the destination address with high heat degree can be increased, the occupation of bandwidth resources is reduced, and the network acceleration effect of data transmission is ensured.

if the receiving times are equal to the interval adjustment threshold, keeping the detection interval of the network detection task unchanged;

Optionally, the adjusting module 304 is further configured to:
and at the starting moment of each detection interval of the network detection task, adjusting the interval adjustment threshold according to the receiving times of the data traffic pointing to the destination address counted in the duration of a plurality of historical detection intervals.
Optionally, the executing module 303 is further configured to:
and if the data transmission state between the local address and the destination address is detected to be abnormal, immediately triggering network detection, and resetting the duration and the detection interval of the network detection task.
Optionally, as shown in fig. 4, the apparatus further includes an adjusting module 304, configured to:
and adjusting the hot address threshold according to the time difference between the current time and the execution time of the last network detection.
In the embodiment of the invention, when data traffic pointing to a destination address is received, whether a network detection task aiming at the destination address exists locally is judged; if yes, adding one to the recorded receiving times of the data flow pointing to the destination address, otherwise, creating a network detection task; and when the receiving times are more than the preset hot address threshold value, executing the network detection task and resetting the duration of the network detection task. Therefore, the heat degree of the destination address can be judged and identified by counting the data transmission times of the destination address, and the detection frequency of the network detection task for the destination address is adjusted based on the heat degree, so that the detection frequency of the destination address with low heat degree can be reduced, the detection frequency of the destination address with high heat degree can be increased, the occupation of bandwidth resources is reduced, and the network acceleration effect of data transmission is ensured.
