Step 101, obtain the IP address of service-user and the IP address of alternate servers, alternate servers is connected with at least one server in application service system;
Step 102, the IP address of service-user and the IP address of other alternate servers of application service system is sent to each alternate servers, to make each alternate servers send network detection request to the IP address of service-user and the IP address of other alternate servers nodes, thus the network-in-dialing situation of the network-in-dialing situation obtained between each alternate servers and alternate servers and service-user;
Step 103, the server according to each server in application service system and alternate servers is communicated with situation, determines the server as network coordinate datum mark, and coordinate basis Network Based point builds network coordinate system; Wherein, server be communicated with in network-in-dialing situation, alternate servers and application service system that situation comprises between alternate servers the network-in-dialing situation between server, network-in-dialing situation between each server in application service system;
Step 104, is communicated with situation based on each server in the network-in-dialing situation of alternate servers and service-user and application service system and service-user, carries out subregion, and determine the server providing application service in each subregion to service-user.
Preferably, in step 101, before obtaining the IP address of service-user and the IP address of alternate servers node, also comprise: obtain the information on services of service-user under application service system; According to information on services, estimate current service quality and the current network service environment of application service system; If the current service quality of application service system exceeds the threshold value of setting, or the current network service environment of application service system becomes bad, then adjudicate and expand application service system.
Concrete, obtain the information on services of service-user under application service system and comprise: the serve log information of all users that acquisition system stores, as service time, service quality, service fee etc. information; From serve log information, read journal file, and resolve log file contents, and the preliminary treatment such as filtering and noise reduction are done to the USI user service information parsed; Utilize linear regression, the models such as minimum variance perform mathematical calculations to pretreated USI user service information, estimate that application service system is for the current service quality of each user and current network service environment, and the service quality of predicted application service system for each user and the variation tendency of web services environment; According to estimated value and predicted value, whether judgement is expanded application service system.Such as, if estimate application service system to exceed the threshold value of setting for the current service quality of all users (threshold value of setting refers to that the current service quality of application service system for all users is lower than the ratio of projected service quality, as 30%), then adjudicate and application service system is expanded; If lower than application service system stable operation threshold value, (application service system stable operation threshold value refers to that the current service quality of the application service system of setting for all users is lower than the ratio of service quality during application service system stable operation for the current service quality of all users to estimate application service system, as 10%), then adjudicate and application service system is not expanded; If estimating application service system is between above-mentioned two threshold values for the current service quality of all users, then whether application service system is expanded according to the predicted value judgement of the current network service environment of application service system, if the current network service environment of application service system becomes bad, then adjudicate and application service system is expanded, otherwise judgement is not expanded application service system.
After judgement is expanded application service system, perform said method process step 101 to step 104.In said method flow process, the IP address of alternate servers node obtains by initiating request to the operator belonging to alternate servers, this avoid increase high cost and set up new server.The IP address of the service-user of application service system extracts from the USI user service information obtained, such as, obtain the serve log information of all users that application service system stores, read and resolve the journal file in serve log information, obtaining the IP address of each service-user.
In step 102, IP address list is merged in the IP address of each alternate servers obtained and the IP address of each service-user by application service system, and according to the IP address of alternate servers, send the IP address of service-user and the IP address of other alternate servers of application service system to each alternate servers, in the IP address list that namely alternate servers receives, do not comprise the IP address of this alternate servers self.
Each alternate servers using the IP address of the IP address of service-user that receives and other alternate servers nodes as destination address, periodically send network detection request to destination address, and receive network detection data, the network detection data received are sent to application service system, make application service system obtain the network-in-dialing situation of network-in-dialing situation between each alternate servers and alternate servers and service-user.
Wherein, ping detection information bag is included but not limited in the network detection request sent.
The network detection data that alternate servers receives comprise network delay information and the network-in-dialing information of at least one link between alternate servers and other alternate servers, or the network delay information of at least one link between alternate servers and service-user and network-in-dialing information.
The network detection data that application service system sends according to each alternate servers, by carrying out filtering and denoising to network detection data, obtain effective metrical information, according to the IP address of effective metrical information and alternate servers, calculate the network-in-dialing situation between each alternate servers; According to the IP address of effective metrical information and each service-user, the network-in-dialing situation of alternate servers and service-user.
Application service system, according to the network link situation between each alternate servers of calculating acquisition, tentatively draws the network link condition diagram between each alternate servers; In conjunction with active service node physical location information, belonging network provider title, form the network link hum pattern between alternate servers entity.
Server connection situation in step 103 comprises the network-in-dialing situation between the network-in-dialing situation between the server in network link situation, alternate servers and the application service system between each alternate servers, each server in application service system; Wherein, the network link situation between each alternate servers is determined according to step 102.Because alternate servers is connected with at least one server in application service system, therefore, based on the network link situation between each alternate servers, and the network link situation of alternate servers when being connected with at least one server in application service system, the network-in-dialing situation between the server in alternate servers and application service system can be determined.Network-in-dialing situation between each server in application service system is stored in application service system, application service system according to the network detection data of the intrasystem each server feedback received, can be resolved and store the network-in-dialing situation between each server in application service system.
Preferably, in step 103, server according to each server in application service system and alternate servers is communicated with situation, determine several servers as network coordinate datum mark, server as network coordinate datum mark both can be the server in application service system, also can be alternate servers.Preferably, determine that the server as network coordinate datum mark should meet following requirement simultaneously:
(1) as network coordinate datum mark server between distance should be greater than distance between other servers;
(2) as the server that the server of network coordinate datum mark is near backbone network (POP).
(3) number as the server of network coordinate datum mark should be larger than network coordinate number of dimensions.
In addition, the number as the server of network coordinate datum mark is determined according to the disposal ability of application service system.In general, the calculating of network coordinate needs consumption calculations resource, and is that exponentially increases, and grid reference point is more, and the accuracy of network coordinate is higher.Therefore, the disposal ability determination datum mark number according to application service system is needed.
Step 103 determines the server as network coordinate datum mark, to obtain network condition figure more accurately, build network coordinate system, obtain the three elements (origin of coordinates of network coordinate, reference axis and coordinate unit), be convenient to the IP address maps of all alternate servers and user in the particular location of network coordinate, obtain the relative position of IP address at network coordinate of all alternate servers and user, be convenient to step 104 pair service-user and carry out subregion, and determine the server that application service is provided in each subregion.
Such as, first, return time cycle (network delay information) of detection information and application service system to the disposal ability of data according to alternate servers, selecting the server number as network coordinate datum mark, is such as N number of.Secondly, find out from the network link hum pattern of alternate servers inter-entity and be in edge and near the server of backbone network pop as the server of network coordinate datum mark; Then, in conjunction with maximum area principle and minimum mean square error criterion, select remaining as the server of network coordinate datum mark.
After step 103 determines the server as network coordinate datum mark, coordinate basis point Network Based builds network coordinate system, is specially:
Network detection data between N number of grid reference point that acquisition is determined, comprise the network delay data between N number of grid reference point;
According to the network delay information between every two grid reference points, preset initial value and the error range of the space length of every two grid reference points in network coordinate;
In error range, calculate mean square deviation between the initial value of the space length of every two grid reference points in the network coordinate network delay corresponding with it and;
Using the initial value of the mean square deviation that calculates and the space length of minimum two grid reference points in network coordinate as the network coordinate value (physical location) of these two grid reference points in network coordinate;
According to the network coordinate value of these two grid reference points in network coordinate, determine the network coordinate value of each grid reference point in network coordinate, set up the mapping relations between the IP address of each grid reference point and the network coordinate value determined simultaneously.After setting up network coordinate according to grid reference point, perform step 104.
Preferably, step 104 specifically comprises:
Step one: based on alternate servers and service-user be communicated with each server in situation and application service system and service-user be communicated with situation, determine the coordinate points of service-user under network coordinate system; Wherein, alternate servers is determined by step 102 with the situation that is communicated with of service-user, and each server in application service system is stored in application service system with the situation that is communicated with of service-user.Determine all alternate servers and the service-user network coordinate value in the network coordinate system that step 103 is set up, by the IP address maps of all alternate servers and service-user in network coordinate, and obtain the relative position of IP address in network coordinate of all alternate servers and service-user.
Step 2: the coordinate points according to service-user carries out subregion, is communicated with situation according to each subregion server, determines the server providing application service in each subregion.Concrete, according to the coordinate points of service-user, service-user is carried out cluster subregion, and determine the centroid position in each cluster areas; From server connection situation, obtain the coordinate of each server, the server nearest with the centroid distance in cluster areas is defined as the server providing application service in cluster areas.
Wherein, Cluster clustering algorithm can be adopted to carry out cluster subregion to service-user, and determine the centroid position in each cluster areas.Certainly, other algorithms also can be adopted to carry out cluster subregion.The process of Cluster clustering algorithm is:
Step a: according to the coordinate points of all service-users, initialization is used for carrying out the selection matrix of cluster subregion and suitable matrix to service-user coordinate;
First, according to the coordinate points of all service-users, set up the matrix comprising all coordinate points.Concrete, utilize Euclidean distance as measurement index, select the negative of the square distance between any two coordinate points as the similarity s (i, k) between described two coordinate points, similarity s (i, k) refers to data point x
kbe suitable as data point x
ithe probability of representative point.According to point-to-point transmission similarity calculating method, utilize network coordinate value, solve the similarity between any two coordinate points, and obtain the similarity matrix [S (i, k)] between all coordinate points
n*n.Solve corresponding similarity matrix [S (i, k)]
n*nobtain class central point.Wherein, n is the number of data point, is each data point x

kthe selected possibility as representative point is also larger.Suppose in the present embodiment that the selected possibility becoming representative point of all data points is identical, namely all s (k, k) are identical value p, wherein, and p<0.
Secondly, initialization is used for the selection matrix R=[r (i, k)] service-user coordinate being carried out to cluster subregion

ithe appropriate level of representative point.In the present embodiment, when initialization selection matrix and suitable matrix, the value of setting selection matrix and suitable matrix is 0.
Step b: cluster iteration.
Step b, by cluster iterative process, can obtain the class central point number of all data points.Specifically comprise following three sub-steps:
Sub-step 1: according to following more new formula, selection matrix, suitable matrix and weight coefficient are upgraded respectively.
According to select information updating formula can obtain above-mentioned selection matrix upgrade after the selection value of information, according to suitable information more new formula can calculate the suitable information value after above-mentioned suitable matrix update.
Wherein, selection information updating formula is:
be about to
result of calculation as upgrade after the selection value of information.
Suitable information is new formula more: if i ≠ k, then
If i.e. i ≠ k, then will
result of calculation as upgrade after suitable information value; Otherwise,
If i.e. i=k, then will
Result of calculation as upgrade after suitable information value.
Sub-step 2: sue for peace to the selection value of information of all data points and suitable information value according to sum formula, finds the class central point of all data points.
Wherein, sum formula is:
Sub-step 3: judge whether information iteration process meets following three stop conditions, meets that one of them is namely out of service.
Described stop condition: 1) exceed a certain maximum number of iterations order; 2) information knots modification is lower than a certain fixed value; 3) the class center selected keeps stable in continuous a few step iterative process.
Step c: judge whether the number at the class center obtained meets the demands, if do not met, then change the deflection parameter p value in step a, repeat above-mentioned steps till the number at the class center of cluster meets the demands, the coordinate points at the class center met the demands is exported as cluster result.
Steps d: according to the cluster result exported, determine the barycenter in each cluster areas.According to the position of the barycenter in each cluster areas determined, determine the network coordinate of the barycenter in each cluster areas.
In above-mentioned steps two, from server connection situation, obtain the coordinate of each server, the server nearest with the centroid distance in cluster areas is defined as the server providing application service in cluster areas.For each cluster subregion determines the server providing application service, and carry out new application service deployment in conjunction with the server resource that the cloud service provider that server is corresponding provides, application service system is expanded.
In said method flow process, application service system need not increase cost and set up new server, and only by the acquisition IP address of service-user and the IP address of alternate servers, the IP address of service-user and the IP address of other alternate servers of application service system is sent to each alternate servers, network detection request is sent to the IP address of service-user and the IP address of other alternate servers nodes to make each alternate servers, by such mode application service system just can be real-time each alternate servers of acquisition between network-in-dialing situation and the network-in-dialing situation of alternate servers and service-user.By the network-in-dialing situation of the network-in-dialing situation between each alternate servers of Real-time Obtaining and alternate servers and service-user, and the server of each server in application service system and alternate servers is communicated with situation and carries out dynamic server disposition, improve flexibility and real-time that application service system carries out server disposition, be conducive to strengthening the autgmentability of application service system, for user provide more efficiently, service quality more flexibly.
