Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the application.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the application.
In order to ensure the stability in the tunnel IPsec established between the office of different regions, need to detect foundation
The stability of the link-quality in the tunnel IPsec.Currently used method is as follows: one tunnel link establishment IPsec of selection, in institute
Probe messages are sent on the tunnel IPsec of foundation.Record is with the delay between the probe messages and response message of like-identified.
According to preset detection statistical interval statistical average delay and packet loss.Average delay refers between preset detection statistics
Every interior, the average value of the delay of all probe messages.Packet loss refers in preset detection statistical interval, sends detection
The difference of the number of the number and reception response message of message, the ratio with the number for sending probe messages.
Wherein, preset detection statistical interval is the statistics that average transmission a delay and packet loss are completed to a link
When, the total number of the probe messages of transmission.Preset detection statistical interval can be specifically arranged according to actual needs.
According to preset detection statistical interval, after statistics obtains average delay and packet loss, with preset delay threshold and
Preset packet loss threshold value is compared, when the average delay be less than preset delay threshold, also, packet loss be less than it is preset
When packet loss threshold value, the satisfactory quality of the link is indicated, can establish the data transmission that safety is realized in the tunnel IPsec；When
Average delay is greater than preset delay threshold, alternatively, indicating the quality of the link when packet loss is greater than preset packet loss threshold value
It is undesirable, the tunnel IPsec cannot be established, needs to switch to another link.
By taking preset detection statistical interval is 5 probe messages as an example: sending probe messages A1, receive and probe messages
A1 identifies identical response message B1, and the delay for sending probe messages A1 and receiving between response message B1 is 100ms；It sends and visits
Literary A2 is observed and predicted, receives and identifies identical response message B2 with probe messages A2, send probe messages A2 and receives response message
Delay between B2 is 80ms；Probe messages A3 is sent, is not received by and identifies identical response message B3 with probe messages A3；
Probe messages A4 is sent, receives and identifies identical response message B4 with probe messages A4, probe messages A4 is sent and receives and ring
Answering the delay between message B4 is 90ms；Probe messages A5 is sent, receives and identifies identical response message with probe messages A5
B5, the delay for sending probe messages A5 and receiving between response message B1 is 110ms.Then in the preset detection statistical interval
In, the average delay of statistics is (100+80+90+110)/4=95ms；Packet loss is (5-4)/5=20%.
If preset delay threshold is 100ms, preset packet loss threshold value is 30%, then due to the average delay of statistics
95ms is less than 100ms, also, packet loss is less than preset packet loss threshold value, indicates that the link-quality is met the requirements, can establish
The tunnel IPsec carries out the data transmission of safety.
If preset delay threshold is set as 90ms, preset packet loss threshold value is 30%, then since being averaged for statistics is prolonged
When 95ms be greater than 90ms, even if packet loss be less than preset packet loss threshold value, indicate that the link-quality is unsatisfactory for requiring, need to cut
Change another tunnel link establishment IPsec.
As shown in the above, it in the mode of above-mentioned selection link, is counted according to a preset detection statistical interval
The link of average delay and packet loss selection, can only determine that the link-quality meets during the preset detection statistical interval
It is required that can only determine that link-quality is met the requirements within a very short time, it not can determine that the link is preset at this
Whether link-quality meets the requirements after detection statistical interval.Therefore, it is impossible to determine the stability of link-quality.
To solve the above-mentioned problems, the method for selection link provided by the embodiments of the present application, a preset detection cycle
Including multiple preset detection measurement periods, according to preset detection cycle count it is accumulative establish duration, the period is average
Delay and period packet loss, can react the link quality level of each link in a longer time section, a chain
The link quality level on road can embody the stability of link link-quality in a preset detection cycle, thus, energy
Enough high link establishment ipsec tunnels of selection quality stability.
It is described in detail below with reference to specific example of the width figure to the application.
Illustrative methods
Fig. 1 is the method flow diagram of the selection link shown in the embodiment of the present application, comprising:
101: according to preset detection cycle, statistics establishes the accumulative of the tunnel IPsec on each link and establishes number, tires out
Meter establishes duration, period average delay and period packet loss, includes multiple preset detection statistics in preset detection cycle
Interval.
102: accumulative according to each link establishes number, accumulative to establish duration, period average delay and period packet loss
Rate determines the link quality level of each link.
103: from each link, selecting the highest link of link quality level, built in next preset detection cycle
The vertical tunnel IPsec.
In one preset detection cycle, sends and be spaced according to preset message, continual transmission probe messages.Two
There are multilinks between end equipment can be arranged a preset priority for each of the links.In the preset detection cycle
Interior, each of the links switch over from high to low according to preset priority, first on the first chain road of preset highest priority
The tunnel IPsec is established, when the link-quality for detecting the first link is unsatisfactory for requiring, switches to priority inferior to the first link
The second chain road establish the tunnel IPsec；When the link-quality for detecting the second link is unsatisfactory for requiring, priority is switched to
The tunnel IPsec is established in third chain road inferior to the second link；And so on, when the tunnel IPsec was all established in all chain roads
When, when the link-quality of the minimum link of preset priority also is unsatisfactory for requiring, returns again to and switch to preset priority
The tunnel IPsec is established in highest first chain road.At this point, completing one cycle switching.
What needs to be explained here is that in a preset detection cycle, if not completing one cycle switching, then it represents that
Some chain roads establish the tunnel IPsec, and the tunnel IPsec was not established in some chain roads；If completing multiple circulation
Switching, then it represents that all at least establish the tunnel IPsec on each link.
It is understood that for a link, being cut if the tunnel IPsec was established in each chain road
To initially set up the moment at the time of shifting to the link establishment tunnel IPsec, what is counted during preset detection statistical interval should
When the average delay of link is greater than preset delay threshold or packet loss greater than preset packet loss threshold value, switch to another
A link is completed at this point, the termination for recording the link is established the moment in tunnel IPsec of the link establishment.Therefore, it obtains
Temporal information in the tunnel IPsec of link establishment, including initially set up the moment and the moment is established in termination；Also obtain at this
The detection statistical information in tunnel IPsec of link establishment, i.e., what is counted during each preset detection statistical interval is averaged
Delay and packet loss.
For any one link, in different cyclic switchings, the tunnel IPsec is established on the link every time,
The temporal information for this time establishing the tunnel IPsec and detection statistical information can be obtained.How many times are then established on the link
Then there is temporal information and detection statistical information that how many statistics obtain in the tunnel IPsec.I.e. for a link, often
The secondary tunnel IPsec of establishing both corresponds to a temporal information and detection statistical information.According to establishing IPsec every time on the link
The corresponding temporal information in tunnel, statistics obtain the accumulative of the link and establish number, accumulative to establish duration, according to every on the link
Secondary to establish the corresponding detection statistical information in the tunnel IPsec, statistics obtains the period average delay and period packet loss of the link
Rate.
For each link, all in accordance with aforesaid way, in a preset detection cycle, counts each link and establishing
The corresponding temporal information in tunnel IPsec and detection statistical information, so that each chain road is established the accumulative of the tunnel IPsec and built
Vertical number, it is accumulative to establish duration, period average delay and period packet loss.
In one example, as shown in Fig. 2, obtaining temporal information and detection statistics that link establishes the tunnel IPsec every time
Information includes:
201: when establishing the tunnel IPsec on the link, acquisition initially sets up the moment；
202: sending probe messages using the tunnel IPsec established on the link and obtained according to preset detection statistical interval
Link is taken currently to detect the resulting average delay of statistics and packet loss；
203: currently detecting the resulting average delay of statistics and packet loss according to link, determine whether link-quality meets and want
It asks, executes 202 if so, returning, obtain link and detect the resulting average delay of statistics and packet loss next time；If not, holding
Row 204.
204: switching to another chain road and establish the tunnel IPsec, obtain to terminate and establish the moment.
Below by taking a link in multiple links between two end equipments as an example, it is described in detail according to preset detection
Statistical interval counts detection statistical information and temporal information that the link establishes the tunnel IPsec every time.
In the tunnel link establishment IPsec, probe messages are sent, receive response report identical with the mark of probe messages
Text counts the delay between probe messages and response message, obtains the corresponding message delay of probe messages.According to preset detection
Statistical interval, statistics receive the sum of the corresponding message delay of probe messages of response message, then divided by receiving response message
Probe messages number, obtain this it is preset detection statistical interval in average delay.
It is counted according to preset detection statistical interval, that is, the number of the probe messages sent is certain, with preset spy
The number for surveying the probe messages of statistical interval setting is consistent, and the response message received may be than of the probe messages of transmission
Number is few.That is, the case where there may be the response messages of some probe messages to receive, and there are packet losses.Therefore, often
The probe messages for sending preset detection statistical interval, count the number of received response message, determine and send probe messages
The difference of number and the number of received response message, then it is default to obtain this divided by the number for sending probe messages with resulting difference
Detection statistical interval packet loss.
The average delay of preset detection statistical interval obtained is compared with preset delay threshold, will be obtained
This it is preset detection statistical interval packet loss compared with preset packet loss threshold value, be less than if meeting average delay simultaneously
Preset delay threshold, also, packet loss is less than preset packet loss threshold value, then it represents that and the link-quality of link is met the requirements,
It can continue to use the tunnel link establishment IPsec.Continue to obtain according to preset detection statistical interval every time according to preset
Detect the average delay and packet loss of statistical interval statistics.
When average delay is unsatisfactory for preset delay threshold or packet loss is unsatisfactory for preset packet loss threshold value,
Indicate that the link-quality of the link is unsatisfactory for requiring, the tunnel IPsec is established in stopping on the link, switches to another link.
It is understood that being counted every time according to preset detection statistical interval in a period of using the link establishment tunnel IPsec
Obtained average delay and packet loss can all establish the detection statistical information in the tunnel IPsec as the link in this time.
In one example, it ensures that the variation for detecting link-quality in time, needs to shorten as far as possible each
Time difference between a preset detection statistical interval.Therefore, there is only one for adjacent detection statistical interval preset twice
Different probe messages.A probe messages are spaced between the preset detection statistical interval counted every time, in this way, every time
When being counted according to preset detection statistical interval, the detection sent earliest in previous preset detection statistical interval is removed
Message is further added by the probe messages sent after previous preset detection statistical interval, forms next preset spy
Statistical interval is surveyed to be counted.In this way, the probe messages that two adjacent preset detection statistical intervals of front and back include every time, only
There are a different probe messages, thus, when the link-quality of the link changes, cracking can count on discontented
The average delay or packet loss required enough switches to another link as soon as possible.
For example: as shown in figure 3, preset delay threshold is 60ms, preset packet loss threshold value is 30%.In link
On the tunnel IPsec of foundation, probe messages T1 is sent, obtains the message delay 50ms of probe messages T1；Probe messages T2 is sent,
Obtain the message delay 60ms of probe messages T2；Probe messages T3 is sent, response message is not received；Probe messages T4 is sent,
Obtain the message delay 45ms of probe messages T4；Probe messages T5 is sent, the message delay 55ms of probe messages T5 is obtained.It is default
Detection statistical interval be 5, then count the corresponding average delay of probe messages T1~T5 be 52.5ms, packet loss 20%.It presses
According to above-mentioned statistical, and so on, the corresponding average delay of statistics probe messages T2~T6 is 50ms, packet loss 20%.
Counting the corresponding average delay of probe messages T3~T7 is 45ms, packet loss 20%.It is corresponding to count probe messages T4~T8
Average delay is 50ms, packet loss 40%.At this point, switching to another since packet loss is greater than preset packet loss threshold value
The tunnel link establishment IPsec.
Wherein, for the first time it is preset detection statistical interval statistics average delay be 52.5ms, packet loss 20%, second
The average delay of secondary preset detection statistical interval statistics is 50ms, packet loss 20%, between the preset detection of third time counts
It is 45ms every the average delay of statistics, the average delay of packet loss 20%, the 4th preset detection statistical interval statistics is
50ms, packet loss 40% are all once establishing the tunnel IPsec detection statistical information obtained as the link.
At the same time, during establishing the tunnel IPsec on the link, it can recorde and initially set up the moment and termination is built
It carves immediately, can also determine the temporal information for once establishing the tunnel IPsec on the link, that is, initially set up the moment builds with termination
Time difference carve immediately between.
Below by taking multiple links between two end equipments as an example, illustrate how to switch between multilink.
By existing multilink between two end equipments, according to preset priority ranking, chain first high in priority
The tunnel IPsec is established in road.According to the method described above, statistical average delay and packet loss on the chain road of highest priority, when
When the average delay and packet loss of the chain road statistics of highest priority are unsatisfactory for requiring, the chain that priority comes second is switched to
Road statistical average delay and packet loss；When the average delay and packet loss that count on the chain road in highest priority are unsatisfactory for wanting
When asking, the statistical average delay of chain road and packet loss that priority comes third are switched to；And so on, until switching to preferential
Grade minimum the statistical average delay of chain road and packet loss.At this point, completing one cycle switching.
If a preset detection cycle is not at this time, the chain road for back switching to highest priority is established
The tunnel IPsec, statistical average delay and packet loss again on the chain road of highest priority, unites when on the chain road in highest priority
When the average delay and packet loss of meter are unsatisfactory for requiring, switch to priority come second the statistical average of chain road delay and lose
Packet rate repeats above-mentioned cyclic switching.
Therefore, in a preset detection cycle, often there is many preset detection statistical intervals, lasting pair
Link-quality is detected, and when a link-quality is undesirable, switches to the tunnel another link establishment IPsec, with
It is switched on link between two end equipments, thus, it is ensured that use the tunnel satisfactory link establishment IPsec.
In one example, the method also includes:
In a preset detection cycle, if reaching preset cyclic switching number, the link-quality of highest priority
It is still unsatisfactory for requiring, stopping switches to another link, wherein establish the tunnel IPsec all on each link to execute
One cycle switching.
If the link between two end equipments passed through multiple cyclic switching, also in a preset detection cycle
It is gradually to switch to the minimum link of priority from the link of highest priority to exist repeatedly, has been more than preset cyclic switching
Number.Then indicate that the link-quality of the multilink between two end equipments is all often unsatisfactory for requiring.At this point, not continuing to cut
It changes, the tunnel use priority highest link establishment IPsec.This is excessively frequent switching between multiple links in order to prevent,
Influence the data transmission between two end equipments.
After the statistics for completing a preset detection cycle, by taking a link as an example, statistics chain road is described in detail and builds
Vertical the accumulative of the tunnel IPsec establishes number, accumulative to establish duration, period average delay and period packet loss.
In one example, it according to preset detection cycle, counts any one chain road and establishes the accumulative of the tunnel IPsec
Number is established, accumulative to establish duration, period average delay and period packet loss include:
Obtain link establish every time the tunnel IPsec temporal information and detection statistical information, establish every time IP tunnel when
Between information be used to indicate the duration of establishing that the tunnel IPsec is established in link this time, establish the detection statistical information packet of IP tunnel every time
Include the average delay and packet loss of at least one preset detection statistical interval statistics；
The number acquisition in the statistics tunnel link establishment IPsec establishes the accumulative of the tunnel IPsec on the link and establishes number；
Establish the temporal information in the tunnel IPsec every time according to link, duration is established in the accumulation for counting link；
The detection statistical information for establishing the tunnel IPsec every time according to link counts period average delay and the period of link
Packet loss.
After the statistics for completing a preset detection cycle, as described above, the time letter of multiple links can be obtained
Breath and detection statistical information.For a link, temporal information and detection that the link repeatedly establishes the tunnel IPsec are obtained
Statistical information.
First, the link establishes the tunnel IPsec every time and all there is record, therefore, energy in a preset detection cycle
It is enough that number is established according to record statistics the accumulative of the link, that is, obtain the number for establishing the tunnel IPsec on the link.
Second, the temporal information that the link establishes the tunnel IPsec every time is had recorded in a preset detection cycle,
The temporal information can be establish the tunnel IPsec every time establish duration；Change temporal information and can also be and establishes IPsec tunnel every time
The moment is established in the starting in road and the moment is established in termination, and that establishes the tunnel IPsec every time with acquisition establishes duration.Therefore, by the chain
The duration of establishing that the tunnel IPsec is established on road every time is added summation, then obtains the accumulative foundation for establishing the tunnel IPsec on the link
Duration.
For example: for the link there are the record that 3 times are established the tunnel IPsec, it is 5 minutes that the 1st time, which is established the tunnel IPsec,
It is 7 minutes that 2nd time, which is established the tunnel IPsec, and it is 4 minutes that the 3rd time, which is established the tunnel IPsec,.The tunnel IPsec is then established on the link
It is accumulative 16 minutes a length of when establishing.
Third, having recorded the detection statistics letter that the link establishes the tunnel IPsec every time in a preset detection cycle
Breath, establish every time IP tunnel detection statistical information include at least one it is preset detection statistical interval statistics average delay with
Packet loss.The average delay for the preset detection statistical interval for including in all detection statistical informations of the link is calculated average
Value, obtains the period average delay of the link.The preset detection for including in all detection statistical informations of the link is counted
The packet loss at interval calculates average value, obtains the period packet loss of the link.
For example: the link there are the record that 3 times are established the tunnel IPsec, unite by the 1st detection for establishing the tunnel IPsec
Count includes: average delay 50ms and packet loss 20%；Average delay 45ms and packet loss 25%；It average delay 65ms and loses
Packet rate 15%；The detection statistical data for establishing the tunnel IPsec 2nd time includes: average delay 30ms and packet loss 15% averagely prolong
When 40ms and packet loss 35%；The detection statistical data for establishing the tunnel IPsec 3rd time includes: average delay 45ms and packet loss
10%；Average delay 35ms and packet loss 25%；Average delay 60s and packet loss 15%.IPsec tunnel is then established on the link
The period average delay in road is 46.25ms, and period packet loss is 20%.
In the manner described above, the accumulative of each link counted one by one between two end equipments establishes number, adds up to establish
Duration, period average delay and period packet loss.Here it no longer repeats one by one.
The following detailed description of the method for selection link provided by the present application.
In one example, the method for selecting link includes:
According to preset detection cycle, statistics establishes the accumulative of the tunnel IPsec on each link and establishes number, accumulative to build
It grows immediately, period average delay and period packet loss, includes multiple preset detection statistics in the preset detection cycle
Interval；
Described according to each link adds up to establish number, accumulative to establish duration, period average delay and period packet loss
Rate determines the link quality level of each link；
From each link, the highest link of link quality level is selected, is established in next preset detection cycle
The tunnel IPsec.
In one example, number is established according to the accumulative of each link, accumulative to establish duration, period average delay, with
And period packet loss, determine that the link quality level of any one link includes:
Determine the accumulative number and the accumulative product for establishing duration established of link as the first value；
The product of the period average delay and period packet loss that determine link is as second value；
Determine link-quality of the ratio of the first value and second value as the link.
Mode as described above, in a preset detection cycle, statistics establishes IPsec tunnel on each link
The accumulative of road establishes number, accumulative to establish duration, period average delay and period packet loss, then according to the following equation really
The link quality level of fixed each link.
Link quality level=(accumulative number of establishing × add up to establish duration)/(period average delay × period packet loss)
It is understood that the accumulative of each link counted in a measurement period establishes number, it is accumulative to build
It grows immediately, period average delay and period packet loss can react in a longer time section, the link of the link
Quality.Therefore, according to the resulting link quality level of above-mentioned formula, the stability of link-quality can accurately be reacted.Link
Credit rating is higher, and the stability of link-quality is better；Link quality level is lower, and the stability of link-quality is poorer.Therefore,
It is ranked up according to link quality level to the link between two end equipments.In next preset detection cycle, according to
The sequence of link quality level from high to low establishes the tunnel IPsec.Then select the highest link of link quality level, it is believed that the chain
The link-quality stability highest on road uses the tunnel link establishment IPsec in next preset detection cycle at first.
Using the high tunnel link establishment IPsec of link-quality stability, the switching between link is reduced, increases the steady of the tunnel IPsec
It is qualitative, that is, improve the stability of data transmission between two end equipments.
In one example, the method also includes:
The mark of probe messages is set, and high 16 of the mark of probe messages are the process number for transmitting probe messages, detection
Low 16 of the mark of message are the serial number for sending probe messages.
In the prior art, the mark of probe messages, when the probe messages quantity of transmission is very big, is sent out using random number
The mark for the different probe messages sent may be identical, mistake occurs when will lead to statistical time lag and packet loss.
In order to ensure sending the uniqueness of probe messages, the mark that probe messages are arranged in the application example is not used at random
Number mode.The tunnel IPsec established on the link is multi-process, and each tunnel IPsec is sending probe messages.Detection report
Text is identified as 32, high 16 process numbers for being set as sending the probe messages；Low 16 are set as in the tunnel IPsec
In process, the serial number of the probe messages, i.e., low 16 are indicated in the process in the tunnel IPsec, which is which is a
The probe messages sent.
High 16 are process number, therefore, high 16 differences for the probe messages that the process in the different tunnels IPsec is sent；?
In the process in the same tunnel IPsec, probe messages cannot can only send simultaneously two detection reports by transmission one by one
Text, therefore, the serial number of probe messages are different, then low 16 differences of probe messages.I.e. in the process in the same tunnel IPsec
In, low 16 of previous probe messages, than low 16 few 1 of the latter probe messages.To, it is ensured that the mark of the probe messages
The uniqueness of knowledge avoids mistake occur when statistical time lag and packet loss.
According to above content it is found that example provided by the present application, can not only determine the link quality level of link, indicate
The stability of the link, thus the tunnel link establishment IPsec for selecting stability high；The probe messages of transmission can also be set
Mark, it is ensured that the uniqueness of the mark of each probe messages, and then ensure the uniqueness of the mark of response message, to avoid statistics
There is mistake when delay and packet loss.
