As can be seen from the above embodiments, each terminal device of user side can pass through self-organizing sub-clustering and selection cluster head section
Point is divided into the CDN sub-clustering being made of one by one cluster head node and several ordinary nodes, and in each CDN sub-clustering, by
Meet CDN service node of the terminal device as user side as cluster head node, and other terminal devices in cluster, that is, common
Node can carry out access to content by cluster head node, set up CDN net between each terminal device of user side to realize
Network.In the following, will be described in detail in the embodiment of the present application two and set up CDN network for user side and carry out access to content
Method.
Embodiment two
Contents access method provided by one based on the above embodiment, in order to realize that setting up CDN network in user side goes forward side by side
Row access to content, the embodiment of the present application two have also listed a kind of access to content framework based on terminal device, as shown in Figure 2.
Existing CDN network framework is still used in network side, and has affixed one's name to CDN server, i.e. CDN clothes in network lateral edge portion
Business node.In user side, each terminal device is by self-organizing sub-clustering and chooses cluster head node, is divided into one by one by cluster head section
The CDN sub-clustering of point and several ordinary nodes composition.Wherein, in each cluster, by meeting the terminal device as cluster head node
As the CDN service node of user side, and other terminal device, that is, ordinary nodes in cluster, can be carried out by cluster head node in
Hold access.And when carrying out access to content, ordinary node can be by locality connection, such as WIFI heat to the access of cluster head node
Point connection is to complete, and cluster head node can be by remotely connecting, as cellular network connects to the access of network side CDN service node
Fetch completion.
The access to content process after the completion of the clustering process and sub-clustering that are directed between terminal device respectively is carried out below
It is described in detail.
(1) self-organizing sub-clustering is carried out between terminal device and choose the process of cluster head
Firstly, scene for the specific business, marks off a region, using each terminal device in the region as using
Family node, and preset out to the relevant influence factor of selection this event of cluster head node and with each influence factor pair
The weighted value answered.Specific influence factor is network insertion rate Rate, set meal residual flow FRes, remaining capacity BRes, with
And mobility Mobility, weighted value corresponding with this four influence factors is respectively WRate、WFRes、WBRes、WMobility.Wherein,
Weighted value in the area for each influence factor of each user node configuration is consistent, is such as directed to this region, each shadow
The weighted value of the factor of sound may respectively be WRate=0.3, WFRes=0.2, WBRes=0.4, WMobility=0.1, and it is directed to each
The value of influence factor needs in the same order of magnitude in user node.In addition, the access content of each user node is shared
Wish value WWill1 or 0 can be set as according to the selection of each terminal user.
Further, each user node can be corresponding according to the corresponding value of each affecting parameters, each affecting parameters
Weighted value, access content share wish value calculate separately out itself according to following self-organizing election algorithms and be chosen as cluster head
Total weighted value W of nodeNode, self-organizing election algorithm is as follows:
WNode=(Rate × WRate+FRes×WFRes+BRes×WBRes+Mobility×WMobility)×WWill
Wherein, network insertion rate Rate:Rate > 0, weight WRate；Set meal residual flow FRes:FRes > 0, weight
For WFRes；Remaining capacity BRes:BRes > 0, weight WBRes；Mobility Mobility:Mobility >=0, weight is
WMobility；It accesses content and shares wish value WWillIt is 0 or 1, terminal user is ready that providing content access service is then 1, no
It is then 0.And WRate+WFRes+WBRes+WMobility=1.
It in specific implementation,, should if total weighted value is 0 after each user node calculates itself total weighted value
User node begins preparing reception as the user node that can not be selected as cluster head node, not overseas broadcast itself weight
The total weighted value for other user nodes that total weighted value is not zero；If total weighted value is not 0, the user node is as candidate cluster
First node, the total weighted value of overseas broadcast itself within the scope of preset signalc threshold, and other user node broadcast are not received
Total weighted value.
Further, the user node for being 0 for weighted value, if the user node receives in preset time threshold
The total weighted value sent to candidate cluster head node, then total weighted value of more each candidate cluster head node, maximum by total weighted value
Candidate cluster head node is as the main cluster head node for providing content access service for it furthermore it is also possible to the secondary big candidate of total weighted value
Cluster head node provides the standby cluster head node of content access service as it, select main cluster head node or standby cluster head node it
Afterwards, which will choose result and is sent to the main cluster head node selected or standby cluster head node.In addition, if the user node is pre-
If first time threshold in do not receive any broadcast, then the user node be used as non-sub-clustering node, subsequent content access still
Directly obtained by network side.
For candidate cluster head node, if candidate cluster head node receives weighted value and is not zero in preset time threshold
User node send be chosen for cluster head node selection as a result, then by it is all be sent to it choose result users save
Point is as using itself as the ordinary node in the cluster of cluster head node, and to the CDN server of network side hair after sub-clustering completion
Send instruction information, so as to network side CDN server after receiving the instructions, can be issued to cluster head node relevant
Content is accessed, it is subsequent to provide content access service by the cluster head node for the ordinary node in cluster.And if by one section
After time, candidate cluster head node do not receive it is any choose as a result, then candidate's cluster head node is also used as non-sub-clustering node, after
Continuous access to content is still directly obtained by network side.In practical applications, since the user node quantity of user side is more, each
User node provide content access service capacity variance is larger and each user node between locality connection signal intensity difference
The factors such as larger are carrying out may be user node number one upper limit value of setting accommodated in each cluster when sub-clustering, also,
Cluster head node can will only meet the ordinary node within the scope of preset signalc threshold and be divided in cluster using itself as cluster head node
In.
Based on this, sub-clustering is completed in the user node in the region, wherein there are small part user nodes due to distance and
The factors such as signal do not enter into any sub-clustering, still use existing access to content mode.Here, non-sub-clustering node carries out content visit
It is described in detail in the process asked no longer the application.
(2) in cluster ordinary node carry out access to content process
After user node in the region completes sub-clustering and selects cluster head, the ordinary node in subsequent cluster carries out content visit
It is preferentially completed by the cluster head node of user side when asking.Ordinary node in certain specific cluster carries out the stream of access to content
Journey, as shown in Figure 3.And the access to content of non-sub-clustering node, cluster head node is directly completed by network side, here no longer
It is discussed in detail.
S301: ordinary node sends content access request to main cluster head node.
S302: ordinary node judges whether main cluster head node is effective.
If so, ordinary node receives the instruction that main cluster head node is sent and prepares i.e. in preset time threshold
The response of reception content, it may be determined that the main cluster head node is effective, continues to execute step S303；
If it is not, ordinary node can determine the main cluster head node failure, step S304 is continued to execute.
S303: the accessed content that main cluster head node is sent is received, wherein the accessed content can be main cluster head
What node had locally cached, it can also be what main cluster head node was requested to network side CDN service node.
S304: ordinary node sends content access request to standby cluster head node, and receives the interviewed of standby cluster head node feedback
The content asked.
Here, the process that ordinary node obtains access content from standby cluster head node can be found in be obtained from main cluster head node
Access the process of content.In specific implementation, if main cluster head node and standby cluster head node fail, which can be with
The cluster head re-initiated chooses process, i.e., the total weighted value sent according to the candidate cluster head node that total weighted value is not zero continues
Cluster head node is therefrom selected, detailed process can be found in the process of sub-clustering and cluster head selection between above-mentioned user node.
To sum up, in the embodiment of the present application, each terminal device can be divided by self-organizing sub-clustering and selection cluster head node
At the CDN sub-clustering being made of one by one cluster head node and several ordinary nodes.Wherein, in each cluster, cluster is used as by meeting
CDN service node of the terminal device of first node as user side, and other terminal device, that is, ordinary nodes in cluster, Ke Yitong
It crosses cluster head node and carries out access to content.User side can only be carried out by the CDN service node of network side compared to the prior art
Access to content, the embodiment of the present application can further promote the speed of access to content, and save ordinary node in progress
Hold flow when access.
