As shown in Figure 1, in the embodiment of the present invention, the handling process of network proximity load balancing method can comprise:
Step 101, determine the carrying status of client to the network distance parameter between the website of website described in the access request of website and described client;
Step 102, according to the carrying status of described network distance parameter, determine the website that the access services of described website is provided to described client.
Flow process can be learnt as shown in Figure 1, and in the embodiment of the present invention, the website of website and the network distance parameter between client are entrained to the access request of website by client; According to the carrying status of network distance parameter in this access request, just can determine the website that website visiting service is provided to client; Compare with the technical scheme that in prior art, each website carries out network distance detection for real user, without preserving and safeguard the network distance parameter library of bulky complex on the local load balancing equipment at website, also without the local load balancing equipment by website, carry out the synchronous of the detection of client distance and network distance parameter, can realize network proximity load balance process simplely, improve the performance of local load balancing equipment, reduce the cost of local load balancing equipment.
During concrete enforcement, flow process shown in Fig. 1 can be implemented by the equipment that can realize its function, such as can be local load balancing equipment, GSLB equipment of website etc., or also the equipment that can realize function shown in Fig. 1 can be set in network specially.
During concrete enforcement, client can adopt multiple format to the access request of website, for example, can adopt HTTP (Hypertext Transfer Protocol, HTML (Hypertext Markup Language)) form etc.
HTTP cookie is that server sends to a segment information of client, client-cache cookie information when client-access some websites.When the same website of client access next time, expired if cookie information does not have, cookie information is attached in HTTP request, send to server.Server can utilize the arbitrariness of cookies inclusion information to screen and regular these information of safeguarding, to judge the transaction status in service process.Whether the most typical application of cookies is to judge registered user's Website login, and user may be pointed out, and whether upper, retains user profile to simplify login formality while once entering this website.The processing that another important application occasion of cookies is " shopping cart " and so on.User may select different commodity within a period of time in the different pages of same website, and these information all can write cookies, so that information extraction while in the end paying the bill.
In an embodiment, the website of website and the network distance parameter between client can be carried in the client cookie that client comprises the access request of website, and step 101 can be specially: determine the carrying status of network distance parameter described in client cookie in described access request.Like this, because the local load balancing equipment of website has been used the continuation information between the next mutual client of HTTP cookie and server, therefore, use client cookie to preserve network distance parameter in the present embodiment, more easily realize, cost is lower.Certainly, in enforcement, also can utilize client to carry aforementioned network distance parameter to some other information in the access request of network.
During concrete enforcement, aforementioned network distance parameter is the network distance parameter between web-site and client, can accurately reflect that the distance of web-site and client is far and near.Network distance parameter can comprise two-way round-trip delay (rtt), hop count (ttl), packet loss (loss) one of them or combination in any, can certainly comprise the data that other can reflect distance distance between web-site and client.In order to make, determining while providing the website of website visiting service to client, to determine result more accurately and reliably, the ageing time scope of network distance parameter can also be set, while implementing, need consider the network distance parameter within the scope of the ageing time allowing.In order to prevent the network attack of malice, in transmitting procedure, can also carry out encryption and decryption processing to the network distance parameter of carrying.
During concrete enforcement, in step 101, determine that client can have numerous embodiments to the carrying status of the network distance parameter between the website of website described in the access request of website and described client, accordingly, under different execution modes, step 102, according to the carrying status of described network distance parameter, is determined to described client and is provided the website of the access services of described website also can have different execution modes.
For example, if step 101 is embodied as: determine that described access request carries the network distance parameter between at least two of described websites website and described client, described at least two websites comprise the website that receives described access request; Step 102 can be embodied as: according to the network distance parameter between described at least two websites and described client, described in determining, described at least two website middle distances, the nearest website of client provides the access services of described website to described client.For example, client is to carrying the network distance parameter between website 1 and website 2 and client in the access request of certain website, at website 1, receive after the access request of client, by more known website 1 than website 2 from client more close to, website 1 directly provides the access services of this website to client.
In this example, if the nearest website of the distance client of determining is not the website that receives client-access request, client can be redirected to definite website.For example, client is to carrying the network distance parameter between website 1 and website 2 and client in the access request of certain website, at website 1, receive after the access request of client, by more known website 2 than website 1 from client more close to, client is redirected to website 2, the access services of this website is provided to client by website 2.
In another embodiment, if step 101 is embodied as: determine that described access request carries the website of the described access request of reception and the network distance parameter between described client, and do not carry the network distance parameter between other websites and described client; Step 102 can be embodied as: determine that the website that receives described access request provides the access services of described website to described client.Still illustrate, client is to carrying the network distance parameter between website 1 and client in the access request of certain website, and do not carry the network distance parameter between other websites and client, at website 1, receive after the access request of client, without relatively, by website 1, directly to client, provide the access services of this website.
In another embodiment, if step 101 is embodied as: determining that described access request is not carried receives the website of described access request and the network distance parameter between described client; Step 102 can be embodied as: determine that the website that receives described access request provides the access services of described website to described client.Still illustrate, client is not to carrying the network distance parameter between arbitrary website and client in the access request of certain website, can determine that access request is not carried receives the website of described access request and the network distance parameter between described client, can receive after the access request of client at website 1, by website 1, directly to client, provide the access services of this website.
In this example, can also insert described access request by receiving the website of described access request and the network distance parameter between described client.During the follow-up like this access request that again receives client, just can, with reference to the network distance parameter of wherein carrying, determine the website of providing services on the Internet to client.
Provide an instantiation below, the concrete enforcement of aforementioned network proximity load balancing method is described.In this example, by client, the client cookie in the access request of website is stored to the network distance parameter between client and web-site, the network distance parameter of carrying in receiving the local load balancing equipment inspection client cookie of client terminal website access request, is redirected to the website nearest with its network distance according to default strategy by client.
As shown in Figure 2, in this example, the handling process of network proximity load balancing method can comprise:
Step 201, client are initiated the access to website www.example.com, and DNS name resolution polling result is website A, and client is initiated the access request to this website to website A;
Now client cookie is exemplified as:
REF＝ID＝4c62c9c50167cdc8:NW＝1:TM＝1234428939:LM＝1234428939:S＝Ab7dvVV8eUsubttY；
The local load balancing equipment of step 202, website A is as the agency between client and website A, determine and in client cookie, there is no the network distance parameter between website A and client, when website visiting service is provided to client, calculate the network distance supplemental characteristic (can comprise two-way contact time delay rtt, hop count ttl and packet loss loss) between website A and client, and be inserted in client cookie, be sent to client and preserved by client;
The network distance example of parameters being inserted in client cookie is:
client_id＝xxxxxxxx:client_ip＝xx.xx.xx.xx；proximity_slb_a_ip＝xx.xx.xx.xx:rtt＝100ms:ttl＝5:pkt_loss＝1％:timestamp＝xxxxxxxx；
Step 203, client are accessed www.example.com again, and now DNS name resolution polling result is website B, and client is initiated the access request to this website to website B;
Now client cookie has carried the network distance parameter of website A, is exemplified as:
REF＝ID＝4c62c9c50167cdc8:NW＝1:TM＝1234428939:LM＝1234428939:S＝Ab7dvVV8eUsubttY；
client_id＝xxxxxxxx:client_ip＝xx.xx.xx.xx；
proximity_slb_a_ip＝xx.xx.xx.xx:rtt＝100ms:ttl＝5:pkt_loss＝1％:timestamp＝xx?xxxxxx；
Step 204, similar with step 202, the local load balancing equipment of website B completes between website B and client network distance parameter in the insertion of client cookie;
The network distance example of parameters being inserted in client cookie is:
proximity_slb_b_ip＝xx.xx.xx.xx:rtt＝200ms:ttl＝6:pkt_loss＝2％:timestamp＝x?xxxxxxx；
Step 205, the follow-up www.example.com that again accesses of client, DNS name resolution polling result is website B, client is initiated the access request to this website to website B;
Now client cookie has carried the network distance parameter between website A and website B and client, is exemplified as:
REF＝ID＝4c62c9c50167cdc8:NW＝1:TM＝1234428939:LM＝1234428939:S＝Ab7dvVV8eUsubttY；
client_id＝xxxxxxxx:client_ip＝xx.xx.xx.xx；
proximity_slb_a_ip＝xx.xx.xx.xx:rtt＝100ms:ttl＝5:pkt_loss＝1％:timestamp＝xx?xxxxxx；
proximity_slb_b_ip＝xx.xx.xx.xx:rtt＝200ms:ttl＝6:pkt_loss＝2％:timestamp＝xx?xxxxxx；
The network distance parameter that the local load balancing equipment inspection client cookie of step 206, website B carries, according to collocation strategy, therefrom the nearest website of chosen distance client provides website visiting service to client; Wherein, collocation strategy can be two-way round-trip delay, hop count and the packet loss in comparing cell distance parameter, and the two-way round-trip delay in also can a comparing cell distance parameter, can arrange according to actual needs;
In this example, suppose that website A compares website B, and the network distance between client is nearer through comparing, the local load balancing equipment of website B redirects the client to website A, by website A, to client, provides website visiting to serve.
Lift again the concrete enforcement of an example explanation aforementioned network proximity load balancing method below.This example illustrates website A and how to process after to the access request of website receiving client, in this example, still by client, client cookie in the access request of website is stored to the network distance parameter between client and web-site.
