Description
Technical field
The present invention relates to a kind of communication technology method more particularly to a kind of uniform method of realization server load and it is
System.
Background technology
General realize of load balancing is at present：Load balancing is made of a clothes multiple servers in a symmetrical manner
Be engaged in device set, every server all has status of equal value, service individually can be externally provided and without other servers
Auxiliary.By certain load balancing technology, a certain service request that outside is sent being evenly distributed in symmetrical structure
On device, and the server for receiving request independently responds the request of client.Equally loaded can mean allocation client request arrive
Server array takes this to provide quick obtaining significant data, and solution largely concurrently accesses service problem.
Load-balancing algorithm common at present, it is equal including the load balancing based on DNS, the load based on the fourth layer technology
Weighing apparatus and the load balancing based on seven layer-switching technologies；Above-mentioned method distribution server using poll, weighting, at least connect,
The selection such as random and response time distribution server thinks suitable server-assignment to terminal client.
1st, the load balancing based on DNS
DNS load-balancing techniques are earliest Load Balancing Solutions, it is by the random name solution in DNS service
It analyses what is realized, can be multiple and different same names of address configuration in the dns server, and finally inquire about this name
The client computer of word will obtain one of address when parsing this name.Therefore, for same name, different clients
Chance obtains different addresses, they also just access the Web server in different address, so as to achieve the purpose that load balancing.
Its advantage is to realize that simple, implementation is easy, at low cost, applied suitable for most of TCP/IP；But shortcoming is also very bright
Aobvious, scheme this first is not load balancing truly, and Http requests are equally distributed to backstage by dns server
On Web server, and without considering the current loading condition of each Web server；If configuration and the place of the Web server on backstage
Reason ability is different, and for most slow Web server by as the bottleneck of system, the strong server of processing capacity cannot give full play to work
With；Secondly do not consider fault-tolerant, if certain Web server on backstage breaks down, dns server still can be DNS request point
It is fitted in this failed server, causes to be unable to customer in response end.Last point is fatal, it is possible to cause quite a few
Client cannot enjoy Web service, and due to DNS cache, caused consequence will continue significant period of time (one
As refresh cycle of DNS when being about 24 small).So in the construction center Web site scheme of foreign latest, seldom use
This scheme.
2nd, the load balancing based on the fourth layer technology
It is that the virtual ip address of Web service, this virtual IP address are set on Fourth Level Interchange machine based on the fourth layer technology
Address is the IP address for the Web server being resolved in dns server, and client is visible.It is answered when client accesses this Web
Used time, the Http requests of client can be received first by Fourth Level Interchange machine, it will in real time be detected based on Fourth Level Interchange technology
The load of backstage Web server carries out fast exchange according to the algorithm of setting.Common algorithm has poll, weighting, at least connects
It connects, random and response time etc..

It is mainly used for realizing that the load balance of Web applications and service quality are protected based on the load-balancing technique that layer 7 exchanges
Card.There are many advantages by comparison with Fourth Level Interchange machine for it：Layer 7 interchanger can not only check the TCP of TCP/IP data packets
And UDP port number, it is handled so as to be transmitted to certain of backstage server, and Http requests can be analyzed more than session layer
URL, different according to URL give different Http requests to different servers handle (can be specific to certain a kind of text
Part, until some file) in addition same URL request can allow multiple servers to respond with load sharing (when client visits
Ask some URL, when initiating Http requests, it will actually establish multiple session connections with server, obtain multiple objects, example
Such as .txt/.gif/.jpg documents, after these objects are downloaded to local, a complete page is just formed).
