Specific embodiment
The application is specifically described with reference to the accompanying drawings of the specification, the concrete operation method in embodiment of the method can also
To be applied in Installation practice.
Fig. 1 illustratively shows the embodiment of the present invention and provides the system architecture that the test method of DNS scheduling is applicable in, should
System architecture may include DNS scheduling system 101, test macro 102, CDN103.
In conjunction with Fig. 1, as shown in Fig. 2, including at least one node in CDN103；The node includes at least one caching clothes
Business device；The cache server accelerates domain name corresponding data cached for caching；It include caching clothes by taking Fig. 2 as an example, in node 1
Be engaged in device 211-213, includes cache server 221-223 in node 2, includes cache server 231-233 in node 3.
CDN103 can also include dns server；Dns server is made of Domain Name Resolver and name server.Domain
Name server, which refers to, preserves the domain name of All hosts and corresponding IP address in the network, and has domain name being converted to IP address
The server of function.The process that domain name is mapped as IP address is known as " domain name mapping ".Access request is sent to CDN in user
Afterwards, dns server carries out global load balancing dns resolution to the acceleration domain name in the access request, this time global load balancing
Dns resolution is used to determine the IP address of CDN cache server.For example, parsing corresponding IP address according to geographical location information.Add
Fast domain name can be understood as the domain name that client's domain name accelerates in public network access CDN, for example, original domain name is
The acceleration domain name of " www.xxxx.com. " on public network has " www.xxxx.com.lxdns.com. ".CDN adds according to different
Fast type projects go out different clients and accelerate domain name, and it may include program request acceleration, webpage acceleration, live streaming acceleration that client, which accelerates type,
Deng correspondingly, accelerating domain name can also divide into program request acceleration, webpage accelerates, live streaming accelerates etc..CDN is directed to different networks
Resource, can go out different acceleration domain names according to different acceleration type projects, and different acceleration domain names may be cooked up not
Same CDN cache server resource is to provide different acceleration services.
After obtaining the IP address of cache server, access request is issued to corresponding cache server；Buffer service
The domain name to be accessed that device is provided according to browser obtains the IP address of this domain name by the dns resolution of cache server, then by
Cache server submits access request to this IP address；After cache server secondary IP address obtains content, on the one hand in local
It is saved, in case use later, the data of acquisition are returned to client by two aspects, complete data service procedure；Client
The data returned by cache server are obtained to show later and complete the data request process entirely browsed.
As shown in Fig. 2, in cache server 211 and cache server 222, being assigned bandwidth in CDN103, use
It is cached in the data for accelerating domain name A.In cache server 223 and cache server 233, it is assigned bandwidth, is used
It is cached in the data for accelerating domain name B.
Due to the complexity of network, cache server can be because of a variety of causes such as network interruption, network fluctuation, load too high
Cause to service it is unavailable or in poor service, influence CDN acceleration effect.DNS dispatches system 101 for the resource tune in CDN
Degree, when determining that access exception occurs in some cache server IP address, for example, determining the cache server in CDN
High load or it is unavailable when, scheduling system 101 can by the corresponding distribution of the acceleration domain name to other servers made in CDN103,
Allow CDN by from client it is nearest and the normal cache server of service access initiate normal response.DNS scheduling with
Afterwards, what access CDN accelerated that domain name generates, which be sent to, which is replaced the request of caching, will gradually be transferred to replacement caching, i.e. bandwidth is from being replaced
It changes caching and has been transferred to replacement caching.In order to guarantee QOS, therefore, to assure that replacement caching can carry this Partial Incremental bandwidth
BwAdd, that is, it needs to meet:
1) the bandwidth upper limit Bw of cache server is replacedMaxReplace current bandwidth BwNow > Bw of cache serverAdd；
2) the bandwidth upper limit NodeBw of node where replacement cache serverMaxNode works as where replacement cache server
Preceding bandwidth NodeBwNow > BwAdd。
In the prior art, due to BwMaxWith BwNow, BwNow and NodeBwNow, NodeBwMaxThere is industry with NodeBwNow
The band data of business relevance, million rank of manual construction is not high as the feasibility of test input；And only construction portion bandwidth
Data can not assess data not plenary session not and will lead to test coverage and is imperfect；Actual bandwidth is continued jitters, and is constructed
Data it is then relatively fixed and actual scene is not inconsistent, the accuracy of test is lower.
If directlying adopt the bandwidth of operating environment on line as test data, due to can not actively construct expected survey
Examination hall scape, need to wait on line occur in operating environment cache server high load or it is unavailable the problems such as when, and need
When user accesses corresponding cache server, DNS scheduling can be just triggered, test period is long, and test coverage is low, is unable to satisfy survey
The needs of examination.
In addition, system is dispatched to online DNS for test, since the scheduling result of test environment will not really give birth to
Effect, therefore, directlys adopt the band data runed on line, and bandwidth can not be allowed to be transferred to replacement caching by being replaced caching, for
Load too high and the excessively high scene of node load are cached, since load does not decline, the DNS system runed on line can still continue
DNS scheduling is carried out, the scheduling result for testing environment and actual scene is caused not to be inconsistent, can not determine that needs are tested to online DNS
Whether the scheduling of scheduling system meets needs.
Test macro 102 is used to monitor the band data in CDN, and interacts with DNS scheduling system, and then test
DNS dispatches system 101.
Based on the above issues, the embodiment of the present invention provides a kind of test method of DNS scheduling, as shown in figure 3, the method
Include:
Step 301: obtaining the current bandwidth data of CDN；
Step 302: being the test bandwidth under the test scene by the current bandwidth data point reuse according to test scene
Data；
Wherein, the test scene is to be determined according to the testing requirement of DNS scheduling system to be tested.The present invention is implemented
DNS scheduling system 101 to be tested in example can dispatch system for the DNS run on line, be also possible to need it is to be tested to
Online DNS dispatches system, can according to actual test it needs to be determined that, it is not limited here.Test scene can be caching
Server high load or unavailable, node high load or it is unavailable, accelerate domain name high load or it is unavailable in it is one or more
Etc. scenes.
Step 303: obtaining the scheduling result of the DNS scheduling system to be tested, the scheduling result is described to be measured
The DNS scheduling system of examination is determined according to the test band data；
Step 304: according to the scheduling result, determining whether the DNS scheduling system to be tested meets the requirements.
By the above method, test scene is determined according to the testing requirement of DNS scheduling system to be tested, according to checkout area
The current bandwidth data point reuse is the test band data under the test scene by scape；Actively construct expected test
Scene meets the scene runed on practical line, and is able to satisfy testing requirement, and test period is short, and can achieve effective test
Coverage rate；It according to the scheduling result, determines whether the DNS scheduling system to be tested meets the requirements, and then determines scheduling
Influence situation to network bandwidth reduces difficulty of test.
For the needs for better meeting test scene, the required band data in CDN is obtained, it is pre- further to construct
The test scene of phase carries out the test of DNS scheduling.The current bandwidth data for obtaining CDN, comprising: obtain cache server
Current bandwidth data, the current bandwidth data of node belonging to cache server, accelerate domain name shared on cache server
Current bandwidth data.
In the specific implementation process, test macro can obtain the band data of CDN in real time, can be according to the time of setting
Period updates current bandwidth data.
In step 302, it can be stored in advance into configuration file, be surveyed according to the mode that test scene carries out Bandwidth adjustment
Test system, according to the needs of test, reads corresponding configuration file, after the band data for obtaining CDN to carry out Bandwidth adjustment.Band
The configuration of width adjustment can be various dimensions, in the embodiment of the present invention, can be directed to belonging to cache server, cache server
One or more carry out Bandwidth adjustments in node, acceleration domain name.
The embodiment of the present invention provides a kind of test scene for cache server adjustment, for example, under the test scene,
211 high load of cache server then needs the current bandwidth data according to cache server 211, according to the checkout area of high load
Scape determines that cache server 211 is more than the first adjustment amount N of the bandwidth threshold of high load.
As shown in figure 4, be the test band data under the test scene by the current bandwidth data point reuse, it is specific to wrap
It includes:
Step 401: if the test scene is for cache server, it is determined that the first adjustment amount of cache server；
In the specific implementation process, the adjustment amount of the bandwidth of cache server can be adjusted based on ratio and/or based on finger
Definite value adjustment.In conjunction with above-mentioned example, for determining the first adjustment amount based on designated value Bw: if it is determined that cache server 211 is worked as
Preceding bandwidth B wNow is 100M, and the bandwidth threshold Bw for the high load for needing to be scheduled is 200M, then can be by the first adjustment amount N
It is determined as Bw-BwNow=100M.To determine that the method for the first adjustment amount N can be with based on ratio Rate1 are as follows: the first adjustment amount N is
(Rate1-1)*BwNow。
At this point, the current bandwidth data that the test band data of cache server is cache server are adjusted plus described first
Whole amount N.
Separately for example, for cache server fault scenes, however, it is determined that 232 failure of cache server, it is determined that caching
The first adjustment amount N of server 232 is the current bandwidth amount of cache server 232；For example, the current band of cache server 232
Width amount is 200M, and under fault scenes, the bandwidth of cache server 232 need to be reduced to 0, and the first adjustment amount N is 200M.
Step 402: according to the first adjustment amount, the current bandwidth data of node belonging to cache server being adjusted
It is whole, obtain the test band data of node belonging to cache server；
In a kind of specific embodiment, the test band data Node of node belonging to cache server can be equal to section
The current bandwidth data NodeNow of point adds the first adjustment amount N.
Step: 403: according to the first adjustment amount, to the current bandwidth data of each acceleration domain name on cache server
It is adjusted, obtains the test band data of each acceleration domain name on cache server.
If assume to accelerate the network bandwidth that is occupied on each cache server of domain name be it is identical, can be by the first adjustment
It measures in each acceleration domain name in N mean allocation to cache server, with each test band data for accelerating domain name of determination.
In a kind of specific embodiment, it can be adjusted by traversing each acceleration domain name, specific formula:
BwI, j=BwNowI, j+N/D
Wherein, BwI, jTo accelerate test band data of the domain name i on cache server j, BwNowI, jTo accelerate domain name i
Current bandwidth data on cache server j；i≤D；D is the number of the acceleration domain name on cache server j.
It is, of course, also possible to determine bandwidth allocation situation of each acceleration domain name on cache server, really according to actual scene
The weight of bandwidth allocation of the fixed each acceleration domain name on cache server, by the first adjustment amount N according to weight distribution to caching
In a acceleration domain name on server, Bandwidth adjustment is carried out to a acceleration domain name to realize.
By the above method, the test scene generated for node is realized, can reduce test scene establishes difficulty,
Also, the amount of bandwidth of the test scene generated improves testing efficiency closer to real scene.
As shown in figure 5, it is described according to test scene, it is the survey under the test scene by the current bandwidth data point reuse
Try band data, comprising:
Step 501: if the test scene is for node, it is determined that the second adjustment amount of node；
For example, under the test scene, 1 high load of node then needs the current bandwidth data according to node 1, according to height
The test scene of load determines that node 1 is more than the second adjustment amount NodeBw of the bandwidth threshold of high load.In specific implementation process
In, the adjustment amount of the bandwidth of node can be adjusted based on ratio and/or be adjusted based on designated value.For example, to be based on designated value
NodeBw1 is determined for second adjustment amount: if it is determined that 1 current bandwidth NodeBwNow of node is 800M, the height for needing to be scheduled
The bandwidth threshold NodeBw1 of load is 1000M, then second adjustment amount NodeBw can be determined as NodeBw1-NodeBwNow
=200M.To determine that the method for second adjustment amount NodeBw can be with based on ratio Rate2 are as follows: second adjustment amount NodeBw is
(Rate2-1)*NodeBwNow。
At this point, the current bandwidth data that the test band data of node is node add the second adjustment amount NodeBw.
Step 502: according to second adjustment amount, the current bandwidth data of each cache server of node being adjusted, are obtained
To the test band data of each cache server of the node；
It, can be by the cache server under second adjustment amount mean allocation to node, i.e., in a kind of specific embodiment
Bandwidth adjustment the amount NodeBw/C, C of each cache server under node are the quantity of the cache server under node；Node k's
The test band data of each cache server:
Bwn=BwNown+NodeBw/C
Wherein, BwnFor the test band data of the cache server n in node k, BwNownFor the caching in node k
The current bandwidth data of server n；n≤C；C is the number of the cache server in node k.
It is of course also possible to the weight of the Bandwidth adjustment of the cache server under node is determined according to the needs of test scene,
To determine the Bandwidth adjustment amount of each cache server under node.
Step 503: according to second adjustment amount, to the current bandwidth number of each acceleration domain name on each cache server of node
According to being adjusted, the test band data of each acceleration domain name on the cache server of the node is obtained.
If assume to accelerate the network bandwidth that is occupied on each cache server of domain name be it is identical, can be by second adjustment
It measures in each acceleration domain name in NodeBw mean allocation to node, with each test band data for accelerating domain name of determination.
In a kind of specific embodiment, it can be accelerated by each cache server under traverse node and cache server
Each acceleration domain name, with realize it is each accelerate domain name Bandwidth adjustment, specific formula:
NodeBwN, m=Node BwNowN, m+NodeBw/(C1*D1)
Wherein, NodeBwN, mTo accelerate test band data of the domain name m on cache server n, NodeBwNowN, mTo add
Current bandwidth data of the fast domain name m on cache server n；m≤C1；D1 is the number of the acceleration domain name on cache server n；
C1 is the number of the cache server on node k.
It is, of course, also possible to determine bandwidth allocation situation of each acceleration domain name on cache server, really according to actual scene
The weight of fixed each bandwidth allocation on cache server that accelerates domain name, by second adjustment amount according to weight distribution to caching clothes
It is engaged in each acceleration domain name on device, Bandwidth adjustment is carried out to each acceleration domain name to realize.
By the above method, the test scene generated for node is realized, can reduce test scene establishes difficulty,
Also, the amount of bandwidth of the test scene generated improves testing efficiency closer to real scene.
As shown in fig. 6, it is described according to test scene, the band data of the CDN is adjusted under the test scene
Test band data, comprising:
Step 601: if the test scene is for acceleration domain name, it is determined that accelerate the third adjustment amount of domain name；
For example, access accelerates domain name A high load under the test scene, then need according to the current bandwidth for accelerating domain name A
Data determine the third adjustment amount for the bandwidth threshold for accelerating domain name A to be more than high load according to the test scene of high load
DomainBw.In the specific implementation process, accelerating the adjustment amount of the bandwidth of domain name can be adjusted based on ratio and/or based on specified
Value adjustment.For example, for determining third adjustment amount based on designated value DomainBw1: if it is determined that accelerating the current bandwidth of domain name A
DomainBwNow is 400M, and the bandwidth threshold DomainBw1 for the high load for needing to be scheduled is 700M, then can be by third
Adjustment amount DomainBw is determined as DomainBw1-DomainBwNow=300M.To determine third adjustment amount based on ratio Rate3
The method of DomainBw can be with are as follows: third adjustment amount DomainBw is (Rate3-1) * DomainBwNow.
At this point, accelerating the test band data of domain name is to accelerate the current bandwidth data of domain name plus the third adjustment amount
DomainBw。
Step 602: according to third adjustment amount, the current bandwidth data for accelerating the corresponding each cache server of domain name being carried out
Adjustment obtains the test band data of the corresponding each cache server of the acceleration domain name；
If assume to accelerate the network bandwidth that is occupied on each cache server of domain name be it is identical, third can be adjusted
It measures in DomainBw mean allocation to each cache server for accelerating domain name, with the test bandwidth number of each cache server of determination
According to.
In a kind of specific embodiment, the corresponding each cache server of domain name can be accelerated by traversal, it is each to realize
The Bandwidth adjustment of cache server and node, specific formula:
DomainBwL, g=DomainBwNowL, g+DomainBw/(C2)
Wherein, DomainBwL, gTo accelerate test band data of the domain name l on cache server g, DomainBwNowL, g
To accelerate current bandwidth data of the domain l on cache server g；g≤C2；C2 is to take to the caching for accelerating domain name l to be accelerated
The number of business device.
It is, of course, also possible to determine bandwidth allocation situation of each acceleration domain name on cache server, really according to actual scene
The weight of bandwidth allocation of the fixed each acceleration domain name on cache server, by third adjustment amount according to weight distribution to each caching
On server.
Step 603: according to third adjustment amount, to the current band for accelerating node belonging to the corresponding each cache server of domain name
Wide data are adjusted, and obtain the test band data of node belonging to the corresponding each cache server of the acceleration domain name.
In a kind of specific embodiment, the corresponding section of the corresponding each cache server of domain name can be accelerated by traversal
Point, to realize the Bandwidth adjustment of node；The adjustment amount of the real-time bandwidth of node can be where corresponding nodal cache server
DomainBw/ (C2), or according to actual scene, determine bandwidth allocation feelings of each acceleration domain name on cache server
Condition determines the weight of bandwidth allocation of each acceleration domain name on cache server, and then the tune of the real-time bandwidth of the node determined
Whole amount.
By the above method, realizes for the test scene for accelerating domain name to generate, the foundation of test scene can be reduced
Difficulty, also, the amount of bandwidth of the test scene generated improves testing efficiency closer to real scene.
It should be noted that since bandwidth is unable to adjust to 0 hereinafter, if there is cache server adjusted or node
Test band data less than 0, then prompt test band data setting it is unreasonable, to re-start the configuration of test scene.
DNS scheduling system is sent by bandwidth adjusted.A kind of possible implementation, the scheduling result include:
The acceleration domain name of scheduling, scheduling cache server.Specifically, if the cache server of scheduling includes being replaced cache server
With replacement cache server, then scheduling result may include accelerating domain name, and accelerate that domain name is corresponding is replaced cache server
With replacement cache server.
For example, as shown in fig. 7, the cache server for accelerating domain name A to be accelerated before scheduling is 211 He of cache server
Cache server 222, scheduling result are, by the bandwidth scheduling of the acceleration domain name A in cache server 211 to cache server
231。
As shown in figure 8, a kind of possible implementation, described according to the scheduling result, the DNS to be tested is determined
The method whether scheduling system meets the requirements may include:
Step 801: according to the test band data for accelerating domain name, and the caching for accelerating domain name to accelerate before scheduling
Server determines the scheduling bandwidth amount for accelerating domain name；
In conjunction with Fig. 7, however, it is determined that scheduling result is by the bandwidth scheduling of the acceleration domain name A in cache server 211 to caching
Server 231.At this point, accelerating the scheduling bandwidth amount of domain name A is the test amount of bandwidth for accelerating domain name.
Step 802: according to the scheduling bandwidth amount for accelerating domain name, and the caching clothes for accelerating domain name to accelerate after scheduling
Be engaged in device, determine scheduling after the cache server bandwidth scheduling amount and the cache server belonging to node bandwidth scheduling
Amount；
In a kind of specific embodiment, it can determine CDN Bandwidth adjustment amount according to the real process of scheduling, that is, subtract
It is replaced the bandwidth of cache server less, increases the bandwidth of replacement cache server.
Specifically, may include:
Step 1: each cache server list of the acceleration domain name A before traversal scheduling, by acceleration domain name A in each caching
Bandwidth on server removes；
For example, however, it is determined that in scheduling result, the cache server that do not replace, the then acceleration domain name after dispatching accelerates
Cache server list LafterThe cache server list L that acceleration domain name before=scheduling acceleratesbeforeThe caching being replaced
Server；If it is determined that there are the cache servers of replacement in scheduling result, then the buffer service that the acceleration domain name after dispatching accelerates
Device list LafterThe cache server list L that acceleration domain name before=scheduling acceleratesbeforeCache server+the replacement being replaced
Cache server.
For example, determining that accelerating the test band data of domain name A is DomainBwA, it is responsible for accelerating the corresponding caching clothes of domain name A
The bandwidth decrement of business device n is DomainBwA/Cbefore, CbeforeIt is to be responsible for accelerating the correspondence buffer service of domain name A before scheduling
The quantity of device；
After DNS scheduling, being responsible for accelerating the bandwidth increment of the cache server m of domain name A is DomainBw/Cafter, Cafter
It is the quantity of the cache server after scheduling；If a cache server all accelerates acceleration domain name before and after scheduling,
Then the Bandwidth adjustment amount of the cache server is DomainBw/Cafter-DomainBw/Cbefore。
Step 803: if it is determined that belonging to bandwidth scheduling amount and the cache server after the scheduling of the cache server
The bandwidth scheduling amount of node meet the bandwidth requirement of cache server and the node, it is determined that the DNS tune to be tested
Degree system is met the requirements.
For example, however, it is determined that the amount of bandwidth of node declines, less than the bandwidth upper limit of the high load of node；If it is determined that caching
The amount of bandwidth of server declines, less than the bandwidth upper limit of the high load of cache server；Then determination does not need to dispatch again.
A kind of possible implementation, since bandwidth transfer gradually comes into force, it can be assumed that bandwidth transfer process is line
Property, it is assumed that the time come into force completely is T, as shown in figure 9, the then real-time bandwidth scheduling quantum of cache server are as follows:
1) bandwidth scheduling amount * ((current time-scheduling time)/T) current time-scheduling time < T
2) bandwidth scheduling amount current time-scheduling time >=T
By accelerating the test band data and scheduling result of domain name, it can also determine that the CDN of test is every in scheduling process
Whether a cache server and node meet dispatching requirement, can directly determine out the influence situation dispatched to bandwidth, broadening
Test can verify that range, be conducive to targetedly improve the progress that DNS is dispatched.
By accelerating the test band data and scheduling result of domain name, the CDN tested each caching clothes after scheduling are determined
Business device and node whether meet dispatching requirement, the influence situation dispatched to bandwidth can be directly determined out, widened test can
Verify range.
In the embodiment of the present invention, it can be directly accessed operating environment on line, the real-time bandwidth data of CDN are obtained, according to survey
Examination needs to be adjusted the band data of CDN in a test system, is not only bonded practical application scene, but also being able to satisfy test need to
It asks, improves testing efficiency.It, on the one hand can be with furthermore it is possible to the scheduling result of DNS scheduling tests environment is made to act on flow bandwidth
On the other hand the amount of bandwidth for the scheduling for triggering load too high can observe scheduling to band closer to the scheduling needs of scheduling system
