Abstract
The invention discloses a global load balancing method based on HTTP redirection. When a client side inputs a domain name to a user browser, a local DNS server responds to the request of the client side and returns an IP address of global server load balance (GSLB), the user browser sends an HTTP request to the GSLB according to the IP address of the GSLB, the GSLB returns an HTTP data packet of the HTTP request to the user browser, modifies the domain name into a new domain name and transmits the new domain name to the client side, the client side inputs the new domain name to the user browser and requests service from a server which finally provides service for the client side. Compared with a global load balancing method based on a DNS, the global load balancing method has the advantages that the IP address of a user and the specific content requested by the user can be considered, and the method is accurate in positioning and high in accuracy on the premise that data of IP addresses of users are effectively maintained.
Description
Technical field
The present invention relates to content distributing network, specifically relate to a kind of Whole load equalizing method based on HTTP redirection.
Background technology
Based on domain name service (DNS, Domain Name service) Whole load equalizing method, at content distributing network (CDN, Content Delivery Network) in, in fact exactly load-balancing device is deployed in DNS system, when user sends any application connection request, first must ask by DNS system the IP address obtaining server, based on the Whole load equalizing method (GSLB of DNS, Global Server Load Balancing) in the process returning dns resolution result, carry out intelligent decision just, the IP address of a best server is returned to user, make use of the domain name mapping that DNS system is intrinsic, close judges, polling algorithm etc., load balancing can be completed by means of independent of the public DNS system outside system.But DNS system is not naturally do load balancing, so its intrinsic working mechanism can bring certain limitation to GSLB.
As everyone knows, distance between user and local dns server directly affects the accuracy of the GSLB result based on DNS, in some cases, client and local dns server may not in regions, because DNS total system intelligence sees the IP address of local dns server, can't see the IP address of real client, so the request scheduling of client can be gone to inappropriate server.Such as, the IP address of the local dns server of a client manual configuration oneself, when this client moves to other local time, can continue to use this local dns server, in this case, GSLB can provide a distance to cry server very far away of shielding a shortcoming or fault for user according to the IP address of local dns server, causes the delay to the response done by the request of client.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of Whole load equalizing method based on HTTP redirection, is carrying out realizing accurate positioning under the prerequisite effectively safeguarded and precision is high to IP address data.
Technical scheme: for achieving the above object, the Whole load equalizing method based on HTTP redirection of the present invention, comprises the following steps:
(1) client inputs domain name on user browser;
(2) local dns server customer in response end request and return to the IP address of GSLB;
(3) described user browser initiates HTTP request according to the IP address of described GSLB to described GSLB;
(4) described GSLB returns the HTTP packet responding described HTTP request to described user browser, and described HTTP packet comprises the IP address providing the server of service eventually to client;
(5) described GSLB is modified as new domain name domain name simultaneously, and described new domain name is passed to described client, and described new domain name is corresponding with the described IP address of the server of service that provides eventually to client;
(6) described client inputs described new domain name again on described user browser, to the described server for services providing service eventually to client;
(7) provide the server of service for described client end response request eventually to client described in and service is provided.
Beneficial effect: the beneficial effect that the present invention compared with prior art has is the IP address that global load balancing system can examine user, and the particular content that user will ask, can carry out under the prerequisite effectively safeguarded to IP address data with the inventive method, accurate positioning and precision is high.
Accompanying drawing explanation
Fig. 1 is the flow chart of the Whole load equalizing method based on HTTP redirection.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
See Fig. 1, a kind of Whole load equalizing method based on HTTP redirection of the present invention, first client inputs domain name on user browser; Then local dns server customer in response end request and return to the IP address of GSLB; Described local dns server address distributes to described client by client network configuration mode.After described local dns server obtains the domain name mapping request of described user browser, recursive query mode can be adopted to propose inquiry request to other remote servers in DNS system, recursive query mode refers to that each inquiry request is all initiated by local dns server, be subject to filing a request to next remote DNS server again significantly, knowing acquisition result, is the query script of more common practicality.Then described user browser initiates HTTP request according to the IP address of described GSLB to described GSLB; Described GSLB returns the HTTP packet responding described HTTP request to described user browser, described HTTP packet comprises the IP address providing the server of service eventually to client; Described GSLB is modified as new domain name domain name simultaneously, and described new domain name is passed to described client, and described new domain name is corresponding with the described IP address of the server of service that provides eventually to client; Described client inputs described new domain name again on described user browser, to the described server for services providing the IP address of the server of service corresponding eventually to client; There is provided the server of service for described client end response request eventually to client described in last and service is provided.
In the present embodiment, when user inputs a domain name URL in browser address bar, as HTTP: during //www.CDNbook.com, the analysis result that local dns server returns is the IP address of GSLB GSLB, user side browser can initiate HTTP request to this GSLB GSLB, GSLB GSLB returns the HTTP packet of response request to browser, and this HTTP packet can tell that user is to the server request content of certain IP address.In this process, GSLB GSLB also can do an action, revises original domain name URL exactly, and it is rewritten into another new domain name URL ', user after meeting with a response, starts real browsed web content to server request content with this new domain name URL '.Such as, user obtains the IP address of GSLB GSLB: 211.100.48.250, then user is to this IP Address requests content, GSLB GSLB returns to user's HTTP302 response message, in message, the URL that user asks is replaced to new URL containing this IP address of 222.222.96.14, server apparatus corresponding to this IP address is exactly the IP address that user needs again to initiate the equipment of asking.
Preferably, the each period of time T of described GSLB GSLB carries out health examination to the server in CDN system, GSLB obtains the various health and fitness informations of server by the mode of inquiry, if described GSLB can not receive in the response message of server or the response message of server and contains the in-problem information of health status, then this server can not be chosen as best server node.Quality and the health status of the final server selected of guarantee are all preferred, allow to like this locate more accurately.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
