Embodiment

Hit the problem that the information amount of reporting influences the disposal ability of MLSS greatly at can't effectively managing content and the content-on-demand stored on the CDN node in the correlation technique, the present invention proposes: by each CDN node according to the aging condition that sets in advance to the content of storage separately (for example, film, content of multimedia such as music) judgement of wearing out, the content that deletion is aging, and concentrate the information of hitting that reports content, make each CDN node have enough idle storage space, can store new content, can also make the MLSS can the normal process miscellaneous service, avoid handling in a large number the problem that the information of hitting causes the MLSS decreased performance.

Describe embodiments of the invention in detail below in conjunction with accompanying drawing.

Method embodiment

In the present embodiment, provide a kind of management method of content of multimedia, this method can be applicable to the IPTV system, can comprise a plurality of CDN nodes that are used for memory contents in this IPTV system.Fig. 1 is the flow chart according to the management method of the content of multimedia of present embodiment.

As shown in Figure 1, the management method according to the content of multimedia of present embodiment comprises:

Step S102, the CDN node to the program request hit situation of the content of its local storage (for example, the number of times that program request is hit) adds up, and judge according to predetermined judge trigger condition and statistics whether the content of the local storage of this CDN satisfies predetermined aging condition, wherein, predetermined aging condition is that the video-on-demand times of content in the predetermined period is lower than predetermined value; Preferably, this aging condition can be configured according to actual needs, for example, can be set to 48 hours the cycle (also can be the other times section), predetermined value is set to (also can be worth for other) 2 times, like this, wearing out when judging, the CDN node just can be to be lower than twice content by video-on-demand times in 2 days to delete with judged result.

Step S104, the CDN node is the content that satisfies predetermined aging condition (for example, not by program request or only by program request content once, the CDN node can think that this content is aging in two days) deletion with judged result; In this step, the CDN node gives MLSS with the request deletion by the context notification that will need to delete, and agrees this content of deletion back deletion at MLSS, so that MLSS can grasp the content stores situation on each CDN node.

In addition, the trigger condition of being mentioned among the step S102 can be the content stores amount of CDN node reach predetermined value, when predetermined period finishes or its combination.That is to say, the CDN node can be only according to the predetermined period judgement of wearing out, aging like this judgement can be timed execution, particularly, can carry out timing judgement by timer is set; In addition, the CDN node also can be according to the judgement of wearing out of its content stores amount, for example, a ratio value can be set: 80% (also can be worth) for other, like this, when the content of CDN node storage account for its storage total amount 80% the time, memory space is in time cleared up in judgement thereby the CDN node can wear out; Preferably, above-mentioned dual mode can be used in combination, like this, thereby the CDN node can be deleted aging content cleaning memory space in the memory space of CDN node occupied 80%, even and the occupancy of the memory space of CDN is lower than 80% all the time, the CDN node can regularly carry out the content deletion equally, and guaranteeing has idle storage space as much as possible to store new content on the CDN node.

By above-mentioned processing, make the CDN node can realize management automatically, and can make the content deletion action in time to carry out, the problem of avoiding new content in the CDN node, to store content in the storage.

Preferably, the CDN node can found and manage the contents list of the sign of all the elements that comprise its storage, and by the program request situation respective identification in the contents list is carried out mark according to all the elements, wherein, carry out a sowing time the user, the CDN node can be according to the program request situation of reality with the identity marking of content for whether hitting, hit in the current period or miss number of times, particularly, after user's program request once, to should be added one by the hit-count of the content of program request in the contents list, being labeled as this program request hits, the miss number of times of the sign of all the other contents is added one, and it is miss to be labeled as this program request, preferably, for the sign in the contents list, can also be marked with creation-time, each program request is hit or the miss time.Like this, when the CDN node judges whether the content of storing on it satisfies predetermined aging condition, just can be judged by the minimum partial content of video-on-demand times, thereby optimize the processing procedure of judging, avoid unnecessary judgement according to preferential selection of the mark situation of each content identification.

Particularly, when organize content is tabulated, the pairing sign of content that the CDN node can hit program request moves to the afterbody of contents list, and newly-increased content identification is stored in the head of contents list, and the judgement of wearing out of preferential a plurality of signs of selecting to be positioned at the contents list head.Preferably, when selecting to wear out the content of judging, can a pre-configured ratio value, the judgement of wearing out of the CDN node can select to account for this ratio when judging content, for example, it is 2% (or other values) that this ratio value can be set, if the CDN node can be stored 100 contents, then aging when judging this CDN node can select the judgement of wearing out of 2 minimum contents of program request hit-count, when utilizing timer to wear out to judge, can empty when each end cycle that each list item hits or miss mark in the contents list.

Preferably, for the content identification in the tabulation, the CDN node can also be set up Ha Xi (hash) table in this locality, to avoid the occurring Ha Xi conflict between the list item in the contents list.The collocation method of concrete hash algorithm and hash table is known in those skilled in the art, and this paper no longer describes in detail.

In addition, in existing IPTV system, when set-top box users is carried out VOD point sowing time, business module on the distributed flow media node (USS) need be clicked this whether hit situation reports medium location services system (MLSS) immediately, when the video-on-demand times of user in the short time is a lot, each CDN node will be concentrated hit situation is reported MLSS, therefore the amount of information that reports in the short time is very big, can cause MLSS during this period of time to focus on a large amount of reporting informations, thereby influence the disposal ability of MLSS, make that MLSS this moment can not other business of normal process.

Manage and cause concentrating and report the disposal ability of hitting informational influence MLSS and then to incur loss through delay the problem that MLSS goes up other Business Processing at lacking in the correlation technique information of hitting reported, in the method according to present embodiment, the CDN node can report the medium location services system with the pairing sign of the content of hitting by the information of hitting according to the predetermined rule that reports.Predetermined report when reporting rule to reach predetermined quantity, when predetermined report cycle end, report or its combination for sum in the sign of content to be reported.

In the specific implementation process, can report the memory block local setting of CDN node, this reports the memory block to be used to store the information of hitting that need report, and this hits and carries the content identification that user's program request is hit in the information.Report in order to trigger, can dispose a proportion threshold value, when reaching this threshold value, the capacity occupancy that reports the memory block reports the information of hitting of storage, for example, suppose to report the memory block can store the information of hitting altogether corresponding to 512 contents, proportion threshold value is 80%, like this, has stored can trigger when 409 contents are pairing hits information in reporting the memory block and reports.In addition, also can be provided with one and report timer, this reports the timing cycle of timer to be set to 10 minutes (or other times length), and the CDN node just can report the information of once hitting in per 10 minutes like this.And, regularly report also can be used in combination with the mode that reports that proportion threshold value is set.By this mode report of concentrating, can effectively adjust the granularity that reports of the information of hitting, avoid MLSS to handle the hitting information of magnanimity and incur loss through delay processing business.

Preferably, the content of having deleted on the CDN node will continue to preserve on the Centroid of IPTV system, and the user can continue these contents of program request on Centroid.If these contents satisfy the hot broadcast condition, that is, by repeatedly program request (for example, in 24 hours by program request above 20 times), then MLSS can shift the CDN node onto with holding in these to these contents, so that the user continues program request from the CDN node in the certain hour section.

Fig. 2 is the signaling process figure that realizes the VOD broadcast according to the management method of present embodiment in the IPTV system.As shown in Figure 2, this system comprises MLSS, Centroid, fringe node (corresponding to above-mentioned CDN node), electronic program guides (Electronic Program Guide, abbreviate EPG as) and set-top box (Set Top Box, abbreviate STB as), the process of carrying out content-on-demand in this system is as follows:

(21) user operates EPG by remote controller, and EPG sends to STB with the VOD programme information of institute's program request;

(22) STB sends to fringe node by regional signaling transfer point (Regional Signaling Transfer Point abbreviates RTSP as) signaling with the sign of on-demand content;

(23) fringe node notice EPG order program service begins;

(24) fringe node finds corresponding file according to content identification, sends Media Stream to STB;

(25) service finishes after Media Stream plays.In addition, when not having the content of user's program request on the fringe node of subscriber's local, can search other fringe nodes, watch the content of own program request to guarantee the user by MLSS.
