Description
Technical field
The present invention relates to automatically performing of node action in the content distributing network.
Background technology
In content distributing network, Centroid can be stored all the elements, but downstream site and fringe node are often because condition restriction can only be preserved partial content.
In IPTV used, the user belonged to certain node service range.If the program of user's request is not preserved, request can only be turned to other node or even Centroid in the node server at his place.It is a kind of wastes that such request is redirected for Internet resources, simultaneously will be to the offered load increase pressure, and particularly the request to Centroid is redirected, and will have influence on the stability of whole system.
Therefore, avoid asking the generation that is redirected as much as possible.Allow request fringe node under it of user be met as much as possible, or fringe node in its vicinity is met.
Fringe node is often because condition restriction can not be stored all the elements by the inconocenter node, like that so can't satisfy local user's request fully.Be redirected in order farthest to reduce request, can only allow fringe node preserve the most popular program in finite storage space, promptly the user asks more content in a period of time.Like this, the request of just can producing is redirected to non-focus requests for content occasionally to have only the user.Therefore, fringe node needs often from the drop-down focus content of superior node.
Though the upper layer node appointed condition is better than fringe node, the too much request that is redirected to upper layer node also will increase the burden of upper layer node, influence the stability of a system.So upper layer node can be pushed into its subordinate's node with holding in being somebody's turn to do when receiving more focus requests for content.
After request be redirected to take place, if can nigh fringe node satisfy user's request, will alleviate the pressure of Centroid greatly, improve the stability of a system.In order to reach this effect, fringe node can push near fringe node with this focus content after the copy of finishing certain focus content.Owing to the general character of area contents temperature, the content of the non-focus in somewhere node in its vicinity also probably is non-focus content simultaneously.So certain fringe node is after certain content of deletion, fringe node is deleted same content near can notifying.
Fringe node is because the limited storage space of its configuration is redirected the less content of visit that can delete this node in order to store the focus content as far as possible to reduce request.
To this, the method that we adopt: upper layer node holds access times in more and pushes away, lower level node is to the more content of the drop-down redirected number of times of upper layer node, node pushes this content near node it after copying certain content, notify near its same content of knot removal after the knot removal content, the content deletion that fringe node is less with this node access times.
If such method is carried out by manual operation, will have great difficulty, effect is also bad.
Summary of the invention
Technical problem to be solved by this invention is that said method is made strategy, according to the residing position of each node, and the equipment that has, the statistics of user's request is the different strategy of each node configuration.When the trigger condition of strategy satisfied, node can automatically perform the action of appointment in the strategy.

5, dispose drop-down strategy at fringe node D shown in Figure 1, stipulate its in 5 minutes, be redirected to certain requests for content number of times greater than 20 after, to drop-down this content of fringe node A.
At the aging strategy of fringe node D configuration, be less than 10 times if stipulate content access times in 1 week of this node, then delete this content automatically.
6, at each node the counting interface is set.When user capture is stored in the content of this node, calling interface, the normal access count at this node adds up to this content.When node was redirected to other nodes because of the content of not storing user's request with request, calling interface added up at the redirected counting of the visit of local node to this content.
7, all nodes called a tactful checking process in per 5 minutes.This process checks at first which strategy this node has disposed, and for pushing away down strategy and aging strategy is checked normal access counter, is that drop-down strategy is checked the redirected counter of request then.
If the counting of the normal access counter of certain content greater than the tactful trigger value that pushes away strategy down, then produces one according to strategy and promotes to instruct down, push away instruction down and comprise content that pushes away down and the destination node that pushes away down.
If the counting of the normal access counter of certain content less than the tactful trigger value of aging strategy, then produces a deletion action command according to strategy, delete instruction comprises the content of deletion.
If certain content requests is redirected the tactful trigger value of the counting of counter greater than drop-down strategy, then produce a following pull instruction according to strategy, following pull instruction comprises drop-down content and drop-down source node.
At last, the instruction of carrying out said process successively and being produced.
8, node finish copy or and deletion action after, check whether this node disposes copy relaying or deletion relaying.If any, then carry out identical action according to tactful notification target node.
Above-mentioned is a simple embodiment, and in actual applications, each node can come collocation strategy as required.A node can dispose many strategies, also collocation strategy not.
The strategy official hour also can be adjusted.Such as, push away strategy down and can require the access times within a hour or a day to reach how many trigger actions afterwards.Aging strategy can require two the week or all around within access times less than what with regard to trigger action.
The tactful trigger value of strategy regulation can be changed according to node and the concrete specific performance of network.Such as, if the memory space of fringe node is less, network condition is good, can be provided with the tactful trigger value of the strategy that wears out a little bit smaller, deletes non-focus content as early as possible, will ask redirected when needing.If network condition is relatively poor, the fringe node memory space is bigger, can be provided with the tactful trigger value of the strategy that wears out more greatly, keeps some contents, to reduce network traffics more.
The destination node of strategy regulation (pushing away destination node, drop-down source node, copy or and deletion relaying destination node down) then will be provided with according to network topology structure.Push away subordinate's node that destination node can be set to node down, drop-down source node can be set to father node, copy or and deletion relaying destination node can be set to the brotgher of node or subordinate's node.
