Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The embodiment of the invention provides the method that a kind of pair of transmission path is detected, the executing subject of this method be can be
It, can be as shown in Figure 1, application accelerates network can using the network frame of acceleration network using the entry accelerated node for accelerating network
To be made of multiple acceleration nodes, accelerates node to can be mainly divided into entry accelerated node, intermediate acceleration node and outlet and accelerate
Node.
Wherein, entry accelerated node can be used for receiving the data traffic that transmitting terminal is sent to receiving end, then according to pre-
If transmission path pass through that application accelerates in network one or more levels intermediate node is accelerated (may also to be not present in transmission path
Centre accelerates node), data traffic is transmitted to the final jump being connected with receiving end and accelerates node (i.e. outlet accelerates node)
Place, then accelerate node that data traffic is sent to receiving end by outlet.
Entry accelerated node can also accelerate the institute that receiving end is reached in network while transmitting data stream amount to application
There is transmission path to be detected, and select according to detection result or modify preset transmission path, to guarantee preset transmission road
Diameter is always the optimal path of transmission quality.
Entry accelerated node may include processor, memory, transceiver, and processor can be used for carrying out in following processes
The processing that network detection is carried out to transmission path is executed, memory can be used for storing the data and production needed in treatment process
Raw data, such as the receive number of data traffic, the task parameters etc. of network detection task, transceiver can be used for receiving and sending out
The related data in treatment process is sent, data traffic is such as received, sends probe message etc..It is appreciated that an acceleration node can
To realize entry accelerated node, the intermediate function for accelerating node or outlet acceleration node respectively in different data transmission procedures
Energy.
Below in conjunction with specific embodiment, process flow shown in Fig. 2 is described in detail, content can be as
Under:
Step 201, when receiving the data traffic for being directed toward destination address, judge local with the presence or absence of for destination address
Network detection task.
In an implementation, when transmitting terminal accelerates network to send data traffic to receiving end by application, using in acceleration network
The entry accelerated node being connected with transmitting terminal can receive the data traffic of above-mentioned direction receiving end, and based in data traffic
Entrained information determines the network address (i.e. destination address) of receiving end, and then entry accelerated node can be in local lookup
Transmission path that is preset, arriving at the destination location, and then the data traffic can be transmitted to receiving end by the transmission path.Together
When, entry accelerated node can also judge locally whether existing be directed to is somebody's turn to do when determining destination address based on data traffic
The network detection task of destination address.
The networks such as network transmission speed, packet loss, bandwidth availability ratio are passed specifically, network detection task may include
The detection of defeated performance.
Step 202, if it is present the receive number of the data traffic of the direction destination address of record is added one, otherwise
Create network detection task.
In an implementation, entry accelerated node can be after creating the network detection task for some destination address, temporarily
It is not immediately performed the network detection task, but the first receive number of the data traffic of the record direction destination address.So such as
Fruit detects the local existing network detection task for destination address, and entry accelerated node then can be by the direction mesh of record
The receive number of data traffic of address add one；And if detecting the local network detection times not existed for destination address
Business, then can create the network detection task for destination address, and the tasks such as corresponding probe interval, duration ginseng is arranged
Number, while the receive number of the data traffic of destination address can be directed toward with start recording.
Step 203, when receive number is greater than preset hot address threshold, network detection task is executed, and reset network
The duration of detection mission.
It in an implementation, can after entry accelerated node has modified the receive number for the data traffic for being directed toward destination address every time
To judge the size relation of the receive number and preset hot address threshold.When receive number is greater than preset hot address threshold
When, it can be said that the temperature of bright destination address has reached the degree for being worth being detected, then network detection task can be executed, and
The duration of the network detection task is reset, wherein the duration of network detection task refers to that network detection task is created
Afterwards, sustainable existing duration can be based on hot address threshold that is, from being created to the duration being canceled, and during this continues
Judgement, to trigger the execution of network detection task, that is to say, that network detection task after being created, can in etc. it is pending
State executes detection if being triggered in duration, if not being triggered in duration, will not execute detection.
It should be noted that entry accelerated node will be visited based on network after the execution for triggering network detection task
The existing probe interval of survey task, continues to execute network detection task, during this period, is somebody's turn to do when entry accelerated node receives direction
When the data traffic of destination address, the duration of network detection task can be reset.
For example, entry accelerated node created the network detection task for being directed toward destination address at 10 points and 00 second, and
The duration that the network detection task is arranged is 90 seconds, and probe interval is 30 seconds, that is to say, that under normal circumstances, which visits
Survey task will be canceled at 11 points and 30 seconds.
At 10 points and 20 seconds, it is default that entry accelerated node determines that the receive number for the data traffic for being directed toward destination address is greater than
Hot address threshold, immediately trigger network detection task execution, i.e., 10 points 20 seconds, execute primary network detection mission,
The middle time for executing primary network detection mission about at 3 seconds or so, and in the duration of the network detection task, i.e., 11
Before points 30 seconds, will be based on probe interval 30 seconds, and execute network detection task, that is to say, that 10 points 50 seconds, 11 points 20 seconds this two
A time point will execute primary network detection mission respectively.
And at 11 points before 30 seconds, when receiving the data traffic for being directed toward the destination address every time, entry accelerated node then may be used
To reset the duration of the network detection task, the concrete mode of resetting is to receive and be directed toward the destination address
Data traffic time point is starting point, with 90 seconds for extending length, to reset the duration of network detection task, that is,
It says, if at 10 points and 50 seconds, it, can be by the network detection after entry accelerated node receives the data traffic of the direction destination address
The duration of task extends 90 seconds, i.e. the network detection task will be canceled at 12 points and 20 seconds.
It optionally, can be according to the real-time regulating networks of temperature of destination address during executing network detection task
The probe interval of detection mission, correspondingly, can have following processing after step 203: in the single detection of network detection task
It is spaced in duration, statistics is directed toward the receive number of the data traffic of destination address；According to the receive number of data traffic and preset
Interval adjust threshold value, the probe interval of network detection task is adjusted.
In an implementation, entry accelerated node, can be according to initial probe interval after performing network detection task
The execution of network detection task is triggered, while can be as unit of probe interval, in each probe interval of network detection task
In duration, statistics is directed toward the receive number of the data traffic of destination address.Then can at the end of each probe interval, according to
The receive number of the data traffic of statistics and preset interval adjust threshold value, adjust to the probe interval of network detection task
It is whole, and network detection task is executed according to probe interval adjusted, and according to probe interval duration adjusted, statistically
Receive number is stated, then at the end of probe interval after the adjustment, probe interval is adjusted.In this way, can be according to data flow
The receive number of amount judges the temperature of destination address, and so as to the destination address to different temperatures, flexible setting is different
Probe interval.Specifically, the destination address high for temperature can improve detection frequency by way of shortening probe interval
Rate thereby may be ensured that the real-time of detection result, for lower grade destination address, can pass through the side of expansion probe interval
Formula reduces look-in frequency, to save the resource for being used for network detection.
Optionally, the above-mentioned mechanism to probe interval adjustment can be varied, gives two kinds of feasible mechanism as follows:
First, the numerical value based on receive number expands network detection and appoints if receive number is less than interval adjustment threshold value
The probe interval of business；If receive number is equal to interval adjustment threshold value, keep the probe interval of network detection task constant；Such as
Fruit receive number is greater than interval adjustment threshold value and reduces the probe interval of network detection task then based on the numerical value of receive number.
In an implementation, entry accelerated node can be sentenced during adjusting probe interval at the end of each probe interval
In disconnected current probe interval duration, the receive number and preset interval for being directed toward the data traffic of destination address adjust the big of threshold value
It is small.If receive number is less than interval adjustment threshold value, the spy of network detection task can be expanded based on the numerical value of receive number
Survey interval；If receive number is equal to interval adjustment threshold value, the probe interval of network detection task can be kept constant；If
Receive number is greater than interval adjustment threshold value and reduces the probe interval of network detection task then based on the numerical value of receive number.Example
Such as, adjustment threshold value in interval is 5, and probe interval is 30 seconds, when receive number is 4, then probe interval can be expanded (5-4)/5
Times, when receive number is 6, then probe interval can be reduced into (6-5)/5 times.It is above-mentioned exemplarily only to give a kind of adjustment spy
The feasible program at interval is surveyed, the present embodiment does not limit the concrete scheme of the adjustment probe interval of the numerical value based on receive number.
Second, the numerical value based on receive number expands network detection and appoints if receive number is less than interval adjustment threshold value
The probe interval of business；If the probe interval of network detection task is adjusted to by receive number not less than interval adjustment threshold value
Initial value.
In an implementation, entry accelerated node can be sentenced during adjusting probe interval at the end of each probe interval
In disconnected current probe interval duration, the receive number and preset interval for being directed toward the data traffic of destination address adjust the big of threshold value
It is small.If receive number is less than interval adjustment threshold value, the numerical value based on receive number, between the detection for expanding network detection task
Every；If the probe interval of network detection task is adjusted to initial value not less than interval adjustment threshold value by receive number.
It is noted that guaranteeing to visit in order to avoid the probe interval of network detection task infinitely increases or infinitely reduces
Interval is surveyed in controlled range, maximum value and minimum value has can be set in the probe interval of network detection task, no matter connecing
Receive why number is worth, probe interval adjusted is not more than the maximum value or is less than the minimum value, if spy adjusted
It surveys interval and is greater than maximum value, then value is maximum value, similarly, if probe interval adjusted is less than the minimum value, value
For minimum value.
Optionally, during adjusting probe interval, can according to statistics receive number to interval adjustment threshold value into
Row adjustment, corresponding processing can be such that at the beginning of each probe interval of network detection task, according to multiple history
The receive number of the data traffic of the direction destination address counted in probe interval duration is adjusted interval adjustment threshold value.
In an implementation, entry accelerated node, can be in network detection task during executing network detection task
At the beginning of each probe interval, the data traffic of the direction destination address counted in multiple history probe interval durations is obtained
Receive number, then according to these receive numbers come to interval adjustment threshold value be adjusted.
Specifically, can set different history probe intervals corresponds to different addition weights, each history probe interval is calculated
Interior interval adjustment threshold value subtracts the difference that receive number obtains, then respectively by the difference of each history probe interval and addition weight phase
It is cumulative with the interval adjustment threshold value of default after multiplying, threshold value is adjusted so as to obtain new interval.Between such as taking 3 history to detect
Every corresponding addition weight is followed successively by 0.1,0.3,0.5, and corresponding interval adjustment threshold value is followed successively by 3,4,3, corresponding reception time
Number is followed successively by 2,5,4, and the interval adjustment threshold value of default is 3, then adjustment threshold value in interval adjusted is 2.It can be appreciated that in conjunction with going through
The receive number of history statistics, the whole cold and hot degree for measuring destination address, and embody in the form of interval adjusts threshold value, this
Sample, can to avoid in some probe interval data traffic burst reduce, cause probe interval excessive, entry accelerated node can not and
The case where Shi Gengxin optimal transmission paths.
Optionally, when preset optimal transmission paths break down, network detection can be carried out at once, it is corresponding to handle
It can be such that if detecting that the data transmission state between local and destination address is abnormal, trigger network detection immediately, and
Reset the duration and probe interval of network detection task.
In an implementation, Ingress Network node can continue the data transmission state between detection local and destination address, namely
The network state of the local preset transmission path for arriving at the destination location of detection.When detecting that it is different that above-mentioned data transmission state occurs
Chang Shi can then trigger primary network detection immediately, and reset the duration and probe interval of network detection task, in order to
More to reselect out available transmission path in time, avoid causing data traffic long due to optimal transmission paths failure
Time can not transmit.It should be noted that signified data transmission state is abnormal herein, including local do not preset arrives at the destination
The case where transmission path of location.
Optionally, if being not carried out the network detection task for destination address for a long time, can suitably reduce thermally
Location threshold value, corresponding processing can be such that the time difference at the execution moment according to current time and last network detection, to heat
Address threshold is adjusted.
In an implementation, entry accelerated node can start timing after executing network detection each time, by certain
After duration, hot address threshold can be adjusted according to the time difference at current time and the execution moment of last network detection
It is whole.For example, the time difference at current time and the execution moment of last network detection is 5min, then hot address threshold can be subtracted
1, when the time difference is 7min, then hot address threshold can be subtracted 1 again.In this way, in the feelings for not receiving data traffic for a long time
It under condition, can guarantee that preset transmission path has preferably data transmission quality to a certain extent, avoid due to thermally location threshold
Value setting is excessively high, does not execute network detection task for a long time, and cause the data transmission quality of preset transmission path substantially under
When sliding, transmission path can not be replaced in time.
In the embodiment of the present invention, when receiving the data traffic for being directed toward destination address, judge that local whether there is is directed to
The network detection task of destination address；If it is present the receive number of the data traffic of the direction destination address of record is added
One, otherwise create network detection task；When receive number is greater than preset hot address threshold, network detection task is executed, and
Reset the duration of network detection task.In this way, being counted by the data transmission times to destination address, can sentence
Break, identify the temperature of the destination address, is then based on temperature and carrys out detection of the metering needle to the network detection task of destination address
Frequency increases the spy of the destination address high for temperature so as to reduce the look-in frequency for lower grade destination address
Measured frequency had both reduced the occupancy of bandwidth resources, in turn ensured the network acceleration effect of data transmission.
