Description
Technical field
The present invention relates to Internet technical field, more particularly to a kind of page data dissemination method and system.
Background technology
With the development of Internet technology, network becomes more and more important.And with the growth of number of users,
The pressure of the webserver is also increasing.The issue of content of pages and the various operations of correspondence user are all needed
To be completed by server, the increase of large user's amount especially instantaneous subscriber amount, to server bring it is huge
Pressure.
In order to ensure the smooth operation of server, the solution of various load balancing is occurred in that.Load balancing,
English name is Load Balance, and its meaning is exactly to share to be performed on multiple operating units, for example
Web server, ftp server, enterprise key application server and other mission critical servers etc., from
And task is completed jointly.
Software load balancing solution refers to be installed in the corresponding operating system of one or more server
One or more Add-onses realize load balancing, such as DNS Load Balance, CheckPoint
Firewall-1 ConnectControl etc., its advantage is that based on specific environment, configuration is simple, using flexible,
It is with low cost, general load balancing demand can be met.
Software solution shortcoming is also more, because extra running software is installed on every server can consume
The variable amount of resource of system, powerful module, consumes more, so when connection request is special
When big, software can turn into a key of server work success or failure in itself；Software expandable is not
Very well, limited by operating system；Due to operating system Bug in itself, often cause safety problem.
Hardware load balancing solution is the direct installation load balancing equipment between server and external network,
This equipment is normally referred to as load equalizer, because special equipment completes special task, independently of behaviour
Make system, overall performance is largely improved, add diversified load balancing, intelligentized flow
Management, can reach optimal load balancing demand.
Load equalizer has diversified form, in addition to the load equalizer on as independent meaning, has
A little load equalizers are integrated in switching equipment, are placed between server and Internet link, some then with
Be integrated into this function in PC by two pieces of network adapter, and one piece is connected on Internet, one piece of connection
Onto the internal network of back-end server group.
Load balancing be divided into from the geographical configuration that it is applied local load balancing (Local Load Balance) and
GSLB (Global Load Balance, be also region load balancing), local load balancing refers to right
Local server zone does load balancing, and GSLB refers to being individually positioned in different geographical positions
Make load balancing between the server zone for putting, having heterogeneous networks structure.
Local load balancing can efficiently solve the problem that data traffic is excessive, network load is overweight, and not
Need both expensive to pay wages and purchase the remarkable server of performance, make full use of existing equipment, it is to avoid server single-point
Failure causes the loss of data traffic.It has flexile balance policy that data traffic is reasonably distributed to
Server in server zone is born jointly.It is also simply simple even expanding upgrading to existing server again
Ground increases a new server in bundle of services, without changing existing network infrastructure, stopping existing clothes
Business.
GSLB is mainly used in possessing in a multizone website of oneself server, in order that global
User only can just have access to the server nearest from oneself with an IP address or domain name, so as to obtain most fast
Access speed, it can also be used to dispersion website widespread major company of subsidiary is by Intranet (in enterprise
Portion internet) reach the purpose that resource unifies reasonable distribution.
Load balancing has three kinds of deployment way：Route pattern, bridge mode, service directly return to pattern.
Route pattern deployment is flexible, and about 60% user adopts and disposes in this way；Bridge mode does not change existing
Some network architectures；Service directly returns to (DSR) and is relatively adapted to the net that handling capacity is particularly greatly content distribution
Network application.About 30% user uses this pattern.
In the prior art, various load balancing schemes can solve the problems, such as load balancing, but, effect
It is numerous.Meanwhile, the load-balancing mechanism produced for concrete application environment have at present imperfection it
Place.Especially for the problem of load balancing between client server, when page data is issued, mostly
To be published on a server, other servers when needing to obtain the page data, then from the server
Upper acquisition.This scheme is less efficient, while easily there is congestion, needs badly and wants a kind of issue of page data
Scheme is being prevented effectively from the congestion of server aspect.

Specific embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein
Preferred embodiment is merely to illustrate and explain the present invention, and is not intended to limit the present invention.
As shown in figure 1, be a kind of page data dissemination method principle flow chart of the offer of the embodiment of the present invention 1,
Wherein,
Step 11, publisher server will give out information and be published to issue channel.
Publisher server is actually one or one group of server, and being used to issue needs disappearing for user
Breath.These message can be directed to a certain user's, it is also possible to be directed to multiple or whole users'.Hair
Cloth server is only completed the issue of message, is not directly coupled user.
Publisher server is published to issue letter after obtaining the page data for needing issue, it is necessary to this is given out information
Road.Issue channel is a specific packet, and the message that can carry out FIFO according to the principle of storehouse is suitable
Sequence is arranged, or carries out message arrangement according to other modes.The effect for issuing channel is that and will issue
Message is arranged, or can also be stored and given out information itself.
" issue channel " is the container that message is preserved in the transmitting procedure of message.Message is sent to queue
In." issue channel " is the container that message is preserved in the transmitting procedure of message.Issue channel manager is being incited somebody to action
Message is acted as an intermediary when its target is relayed to from its source.The main purpose of queue is to provide and route and protect
Demonstrate,prove the transmission of message；If recipient is unavailable when sending message, issue channel can reservation message, Zhi Daoke
Successfully to transmit it.
" issue channel " is a kind of message processing technique, and it provides Message Processing and issue for any application program
Channel function, no matter these computers whether on same network or whether concurrent connections.
" issue channel network " is any group of computer that can back and forth send message each other.In network
Different computers are ensuring to play the part of different roles during message is smoothly processed.Some of which provides road
By information to determine how transmission message, some preserve the important information of whole network, and some are to send
With reception message.
During " issue channel " is installed, keeper determines which server can be communicated, and sets specific
The special role of server.The computer for constituting this " issue channel " network is referred to as " website ", leads between them
Cross " site link " interconnection.Each site link has one " expense " of association, and it is true by keeper
It is fixed, indicate the frequency that message is transmitted by this site link.
Issue channel is exactly a chained list for message.Message can be regarded as a record, with specific lattice
Formula and specific priority.To issue channel have write permission process can to issue channel according to certain
Rule addition new information；The process for having read right to issue channel then can be read to walk to disappear from issue channel
Breath.Issue channel is lasting with kernel.
In the prior art, mainly there is two kinds of issue channel：POSIX issues channel and system V
Issue channel, system V issue channels are widely used at present.It is newly developed in view of the portability of program
Application program should try one's best using POSIX issue channel.The present embodiment is not limited the form for issuing channel
It is fixed.
System V issue channels are lasting with kernel, only restart or show one issue of deletion in kernel
During channel, the issue channel just can really be deleted.Therefore the data structure of issue channel is recorded in system
(struct ipc_ids msg_ids) is located in kernel, and all issue channels in system can be in structure
Access entrance is found in msg_ids.Issue channel is exactly a chained list for message.Each issue channel has
One queue heads, is described with structure struct msg_queue.The issue channel is contained in queue heads
Message number etc. in bulk information, including issue channel key assignments, ID, group ID, issue channel,
Even have recorded the ID for reading and writing process to issue channel recently.Reader can access these information, it is also possible to set
Put some information therein.
" issue channel " keeper also sets one or more calculating as " routing server " in a network
Machine.Routing server checks the expense of each site link, it is determined that by the most fast of multiple websites transmission message and
Most efficient method, determines how to transmit message with this.
In fact, publisher server is issued by redis memory database delivery systems.
Step 12, client server monitors the issue channel.
Client server is that the server being directly connected to is set up with user terminal, and it will not only be directly connected to user
Terminal, processes the message of user terminal, meanwhile, in order to issue page data in time, in addition it is also necessary to monitor issue
Channel.
Generally, client server is connected to publisher server by web socket agreements.WebSocket
Protocol is a kind of new agreements of HTML5.It realizes browser and server full-duplex communication
(full-duplex)。
It is only capable of realizing unidirectional communication by http in a browser, comet can simulate two-way to a certain extent
Communication, it is but less efficient, and need the server to have preferably support；Socket and xmlsocket in flash can
To realize real two-way communication, by flex ajax bridge, this two work(can be used in javascript
Can it is envisioned that once if websocket accomplished in a browser, will substitute two technologies above,
Is widely used in face of this situation, HTML5 defines WebSocket agreements, can preferably save
Save server resource and bandwidth and reach real-time communication.
In the prior art, in order to realize instant messaging, technology used is all poll (polling).Poll is
In specific time interval (such as every 1 second), HTTP request are sent to server by browser, so
Browser of the newest data to customer side is returned to by server afterwards.This traditional HTTP request's
Banding carrys out apparent shortcoming-browser to be needed constantly to send request to server, but HTTP
The header of request is very long, and the useful data that the inside includes may be a value for very little,
Many bandwidth can so be taken.And the effect that relatively new technology does poll is Comet-use
AJAX.But although this technology can reach full-duplex communication, but still need to send request.
The purpose that HTML5WebSocket is designed seeks to replace poll and Comet technologies, makes visitor
Family end browser possesses as the real-time communication ability of desktop system under C/S frameworks.Browser passes through
JavaScript sends the request for setting up WebSocket connections to server, after connection is set up, client
Just direct exchange data can be connected by TCP with server end.Because WebSocket connection essence
Upper is exactly a TCP connection, so in terms of the stability of data transfer and the size of volume of transmitted data,
With poll and Comet Technical comparings, with very big performance advantage.
In WebSocket API, browser and server only needs to do an action shaken hands, then,
An express passway is formed between browser and server.Just directly can mutually be passed on from one to another with data between the two
Send.Asked, it is necessary to send websocket lines by browser during websocket lines are realized,
Then server sends response, and this process commonly referred to " shakes hands " (handshaking).
WebSocket agreements are substantially an agreements based on TCP.In order to set up one
WebSocket is connected, and client browser first has to initiate a HTTP request to server, this
Request is different with common HTTP request, contains some additional headers, wherein additional header letter
Breath " Upgrade:WebSocket " shows that this is the HTTP request of an application agreement upgrading, server end
Parse these additional headers and then produce response message to return to client, client and server end
WebSocket connections are just set up, and both sides just can freely transmit letter by this interface channel
Breath, and this connection can persistently exist up to the closing company of the one party active of client or server end
Connect.
Particularly, client server giving out information of listening to can be saved in it is local, and belonging to itself
Broadcasted in user.
Step 13, client server gives out information corresponding issue content synchronization to originally according to what is listened to
Ground.
Client server listen to publisher server be published to issue channel in give out information after, obtain this and disappear
Corresponding issue content, that is, corresponding page data are ceased, can be saved in locally, or do not preserve.
Client server monitors the issue channel, if listen to being sent to giving out information for itself, by the hair
Cloth message sends correspondence user；Otherwise, do not deal with.
User is respectively connected to corresponding client server, and is given out information from described in client server acquisition
Corresponding page data.It is corresponding between user and client server, generally can be former nearby according to region
Then or address nearby principle, it is all of with there is the client server that is directed to per family.
Further, during user to access pages data, corresponding contents are obtained in corresponding client server.If
The user can not obtain the page data from corresponding client server, then entered by the client server
Go back source operation, obtain respective page data to other client servers, and store to own user server.
Then there is corresponding client server that page data is sent into relative users again.
In the embodiment of the present invention, will be given out information by publisher server and be published to issue channel；User service
Device monitors the issue channel；Client server is same by corresponding issue content according to giving out information for listening to
Walk local.The scheme of the embodiment of the present invention, can be when page data be issued, and publisher server is carried out
The issue of channel is issued, each client server obtains corresponding page data, improves by monitoring issue channel
The efficiency of page data issue, meanwhile, load balancing configuration is realized between each client server,
Network congestion is not resulted in, system burden is reduced, user experience is greatly improved.
As shown in Fig. 2 be a kind of page data delivery system structural representation of the offer of the embodiment of the present invention 2,
Wherein,
Publisher server 21, issue channel is published to for that will give out information；
Client server 22, for monitoring the issue channel；And given out information correspondence according to what is listened to
Issue content synchronization to local.
Particularly, above-mentioned publisher server 21 includes issue channel, suitable for the principle according to FIFO
Sequence arrangement needs giving out information for issue.
Particularly, above-mentioned client server 22 is connected to publisher server 21 by web socket agreements.
Publisher server 21 is issued by redis memory database delivery systems.
Particularly, said system also includes user terminal 23, for being respectively connected to corresponding client server
22, and obtain the page data from the client server 22.If cannot obtain, by the user
Server carries out back source operation, obtains respective page data to other client servers, and store to itself use
Family server.
In sum, in the embodiment of the present invention, will be given out information by publisher server and be published to issue channel；
Client server monitors the issue channel；Client server gives out information corresponding hair according to what is listened to
Cloth content synchronization is to locally.The scheme of the embodiment of the present invention, can issue clothes when page data is issued
