Description
Technical field
The present invention relates to a kind of distribution method of content information, relate in particular to issuing and the distribution method that distributes and separate content information in a kind of multistage distributed system architecture.
Background technology
In distributed system architecture, need mutual communication between central node and the fringe node, transmit data such as some contents and message, order mutually.After the content that new needs issue arrives central node, central node can be distributed to each fringe node to this content, and notify the time of each fringe node content release, can on each fringe node of the whole network, issue simultaneously according to preset time to guarantee fresh content.So, how to guarantee the success rate and the reliability of big data quantity content distribution, and each fringe node carries out the issue of content in required time simultaneously with the cost of minimum, become the hot issue in the distributed system architecture research.
The distributed system architecture schematic diagram as shown in Figure 1, central node be responsible for fresh content reception, issue, and to the control of each fringe node and centralized management etc.; Fringe node is responsible for receiving content, the order from central node, and carries out issue of content etc. on time.Central node and each fringe node are by IP network or other network interconnection.
Current, the operation flow that central node carries out down sending content in the distributed system may further comprise the steps as shown in Figure 2:
Step a1, Content Management person are loaded into central node to the time of new content information and content release;
Step a2, central node transmit the new content information and the temporal information of content release to each fringe node;
Step a3, fringe node receive content and the issuing time information that central node transmits, and carry out the preliminary treatment of some load content;
If step a4 success, fringe node returns success message and gives central node;
If step a5 success, central node returns success message and gives Content Management person;
Step a6, edge nodes maintain issuing time information are finished the issue of fresh content at preset time.
Under existing down sending content mode, central node is packed the temporal information of fresh content and issue thereof together and is handed down to each fringe node, safeguards issuing time information by fringe node, finishes the issue of fresh content.So just necessary this important temporal information of storage and maintenance of each fringe node, this will inevitably increase the burden of himself.And, central node only knows whether fringe node has successfully received the content and the predetermined issuing time information of content of its distribution, for fringe node after this whether in the official hour correct execution issued command, central node can't be controlled and manage, and also can't obtain feedback.In addition, existing mode is packed content and issuing time information together and is issued, if the data volume of content is bigger, issuing the probability of makeing mistakes can uprise, thereby can make issuing of the issuing time information probability of makeing mistakes increase simultaneously.
Therefore, the prior art scheme has three defectives: the first, fringe node need be safeguarded issuing time information, and function meeting more complicated and burden are bigger; The second, central node and Content Management person can not omnidistance controls and the process that issues of organize content, can not obtain the feedback that fringe node is finally successfully issued content, it is content distributed or not in the content distributed and unwitting situation of central node and Content Management person of correct time that fringe node may take place; Three, the binding of content and issuing time information issues, and may cause success rate and reliability to reduce.
Summary of the invention
The objective of the invention is to propose a kind of distribution method of content information at the defective that prior art exists, unify the distribution of control content information and issue by central node, to strengthen management and the control of central node to fringe node, simplify the function of fringe node, alleviate the burden of fringe node, improve success rate and reliability that content information distributes and issues better.
For achieving the above object, the invention provides a kind of distribution method of content information, this method may further comprise the steps:
Step 1, central node are preserved described content information and content issuing time after receiving new content information and content issuing time, send content information to fringe node;
After step 2, described fringe node receive described content information, the preliminary treatment that described content information is loaded;
Step 3, described fringe node return preprocessing success message to described central node;
Step 4, described central node receive the preprocessing success message that all fringe nodes return;
Step 5, described central node send the content release order to described fringe node;
Step 6, described fringe node are operated according to described content release command execution content release.
The mechanism that the present invention separately transmits by content and content release message, both can make effective control and the management of central node realization to each fringe node, can higher success rate and reliability also have been arranged so that the distribution of content is more efficient with issue again, reach following effect:
The first, the function and the processing burden of fringe node have been reduced.Fringe node only needs to receive in real time and carry out content or the content release message that central node issues, and need not oneself to keep content distributed time and own timing;
The second, central node can omnidistance control and the process that issues of organize content, can obtain the feedback that fringe node is finally successfully issued content, can avoid fringe node not content distributed or not content distributed in the correct time effectively;
Three, content and issuing time unpack issue, and may improve the success rate and the reliability of content distribution and issue, thereby improve the efficient of whole distributed system.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Description of drawings
Fig. 1 is a distributed system architecture schematic diagram in the background technology;
Fig. 2 carries out the flow chart of down sending content for prior art;
Fig. 3 is the flow chart of the preferred embodiment of the distribution method of content information of the present invention;
Fig. 4 returns the flow chart of issue success message better embodiment for guaranteeing all fringe nodes among the present invention.
Embodiment
The content information that distribution issues can be audio frequency, video, text or image or the like.
Fig. 3 is the flow chart of the preferred embodiment of the distribution method of content information of the present invention, suppose to have new content information as one section video ads, the setting content issuing time is 8: 30 on the 26th April in 2006, content providing server is with this section video ads and all sent to the central node of being responsible for distribution in 8: 30 on the 26th April in 2006, and this section of issuing video ads is specifically carried out following steps:
Step 101 is concrete to be carried out following two steps:

Step 1023, each fringe node are filled into the store path of encrypting in the preprocessing success message.
For example, if central node had received the preprocessing success message that all fringe nodes return before 8: 30 on the 26th April in 2006, then central node sends the content release order to fringe node on time 8: 30 on the 26th April in 2006; If central node has received the preprocessing success message that all fringe nodes return 8: 40 on the 26th April in 2006, then central node sends the content release order 8: 40 on the 26th April in 2006 to fringe node, and writes down this time.
At this moment, video ads has just been realized unified issue under the control of central node.
In order further to guarantee the reliability of the process of issuing, also further comprise after the step 106, after fringe node is successfully issued video ads, return the issue success message to central node.
In order to guarantee that further the fringe node that receives video ads can both issue this video ads, the present invention returns issue at fringe node also have been increased behind the success message and has guaranteed that all fringe nodes return success the step of message, as shown in Figure 4, specifically carry out following steps
Step 201, central node are waited for the issue success message that fringe node returns always, and judge whether that in the time of setting all fringe nodes have all returned the issue success message, if, execution in step 106; Otherwise, execution in step 202;
Step 202, central node resend the content release order to the fringe node that does not return the issue success message,
Step 203, the fringe node that receives described content release order are again carried out the content release operation, issue video ads;
Step 204, fringe node return the issue success message to central node, execution in step 201.
Step 201～204 repetitive cycling receives the issue success message that all fringe nodes return until central node, has so just improved success rate and reliability that content information issues better.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
