A kind of content provider's mobile switch method of content center network, content provider record the current service quantity of each content of its offer, and according to practical mobile demand setting switching serving threshold；Before content provider is mobile, first judge whether the current service quantity of each content at this time is not less than switching serving threshold, if, the full sample of the content is then pushed to the router that its original accesses with the mode for sending sample propelling data packet, so as to which multiple requestors of the content is requested to continue to be serviced by the router of original access, guarantee in its moving process, multiple requestor's continuities；If it is not, then content provider does not execute any additional operations to the content；After content provider completes all current service quantity not less than the full sample push of the content of switching serving threshold, mobile handoff process is completed.Caused by the present invention is solved the problems, such as because of content provider's mobile handoff request message cannot respond, multiple requestor's communication disruptions.
Description
Technical field
The present invention relates to a kind of content provider of content center network (Content Centric Networking) shiftings
Dynamic switching method, belongs to the technical field of mobile communications network.
Background technique
With the fast development of internet, demand of the user to content information becomes clear day by day and strongly.Now, including text
The content service of word, image or video on demand has become the main body of network service.In general, people are not relevant for coming for content
Source, whether being concerned only with the safety of content itself speed, quality or content that perhaps content transmits.But currently with master
Traditional IP framework centered on machine does not adapt to the variation of this upper layer application mode, has been difficult to meet people to content
The demand of acquisition.Therefore, every support technology of content center network CCN (Content Centric Networking) just at
For the research hotspot of Next Generation Internet architectural framework.
Content center network CCN is concerned with content itself, and identifies content using content name (Content Name),
The separation of content and content location can also be realized by content name.CCN also achieves the caching of Web content, can be with
The content is obtained from the neighbouring router for caching the content.In this way, just providing day for safety, mobility and the multicast etc. of data
Right support.
In the content in heart network C CN, content provider can be multiple content requestor services.If content provider
Mobile handoff occurs, if content requestor can not perceive its mobile handoff, the still original of transmission request message to content provider
The communication disruption of multiple requestors is caused so that request message is unable to get response in position.At this point, content provider just needs
Respectively multiple requestors establish handoff procedure, cause signaling overheads big, and handoff procedure is complicated, so the movement of content provider
Journal of Sex Research is very necessary, eager and important.
In CCN, the movement of content provider is affected to normal communication, because needing after content provider's switching
All associated routers noticed in network update routing table, cause request message that cannot promptly and accurately be sent to content offer
Person.In addition, content requestor can not know that data packet caused by network problem or node mobility can not return, influence just
Normal open letter.Furthermore if there is a large amount of content provider moves simultaneously, normal communication can also be impacted.
Now, for the mobile problem of content provider in CCN network, some technical solutions, lower mask have been developed
Body introduction solves the problems, such as where the content provider mobile four major class prior arts and its defect:
The first kind is meeting point (Rendezvous Point) method, and this method is using the support ambulant Position Pipe of CCN
Server is managed as joint, for realizing the name resolution between content name and content provider location.Content provider
After movement, to crossing, server sends message, updates content provider location.Requestor carries out position enquiring within the set time
Afterwards, the server of joint responds, to establish new connection.Its defect is update/inquiry and the FIB of new content name
Foundation to will lead to time delay larger.
Second class is indirection point (Indirection Point) method, which is a permanent server, is used
A series of bindings between maintenance destination prefix (target prefix) and source prefix (source prefix).All arrival
The request of content provider must all arrive first at indirection point, be packaged here to original request, then pass through tunnel style
It is transmitted to current location.So all request packets of user all can first reach indirection point, it is not only easy to cause Single Point of Faliure in this way,
And when indirection point is not on the shortest path of content provider and requestor, it will increase in requestor to a great extent
Hold acquisition time, wastes network bandwidth resources.
Third class is tunnel reorientation method, and the program is that request packet is redirected to the new of content provider using tunnel
Position.After content provider's mobile handoff is to another access point, in order to continue to the request packet of content requestor transmission,
Content provider can send a prefix updates message (PU) to home router.After, all request packets can be all routed to
After the home router of content provider is packaged, the current location of content provider is re-send to.When home router not
When on the shortest path of user Yu content provider current location, which will increase the content of requestor to a certain extent
Acquisition time wastes the bandwidth resources of network.Further, since needing additional prefix that request packet is delivered to correct destination
Cost is delivered based on tunnel reorientation method packet with higher in location.
4th class is the method based on routing, when this method is that content provider will execute mobile handoff, needs upward one
It jumps couple in router and sends switching advertised information, couple in router receives all request packets for being sent to the content provider simultaneously at this time
Caching.After content provider's mobile handoff is to new couple in router, a virtual request " virtual is sent
Interest " message, the message carry the name information of content provider, and network can be according to the longest prefix match of fib table
Principle is forwarded to its router accessed originally, at this moment the all-router of approach will update in fib table with content name pair
The interface message answered.After the router of the former access of content provider receives " virtual interest " message, by caching
Interest message reversely sends content provider to, and subsequent Interest packet can directly be forwarded according to fib table, without
The necessary router by its original access forwards.Although this mode reduces routing update expense and handover delay；But due to
Remain that content name is constant during content provider's mobile handoff, the route aggregation convergence after not accounting for switching is asked
Topic, the entry that will cause fib table is excessive, brings burden to router.Moreover, all intermediate routers will update it is respective
FIB causes the capacity of routing table to increase sharply, when the quantity of content requestor and the increase of mobile handoff frequency, such case
It will be more serious.
Technical solution content in current two related invention patent application documents is introduced again and its defect is as follows:
A kind of " information centre's network mobility management method based on content popularit " (application number
It 201310471355.4) is two kinds to be divided the content into according to content popularit, and the content for being directed to different popularities is real respectively
Apply two different motion management methods: based on agent node and based on network-caching.After content provider is mobile, if interior
Hold popularity and be less than threshold k, then uses the motion management method based on agent node, i.e., interrupted and asked by agent node caching
It asks, and updates content name prefix, interest packet is routed to content provider.If content popularit is greater than threshold k,
Using the motion management method based on network-caching, that is, retransmits interest packet and broadcasted in domain.It is being based on agent node
Motion management method in, Interest packet is re-routed at content provider by updating content name prefix, it is this
The shortcomings that method, is obvious: safeguarding that the signaling overheads in new and old content name prefix mapping is larger.
The method of " a kind of mobile support method in content center network " (application number 201310315590.2) be to
Each router in CCN network distributes a specific position, and assumes that content name was connect originally based on the content provider
Enter the position of router.When content provider complete mobile handoff after, by current Access Router to its original access routing
Device sends handoff completion message, and the current Access Router content provider is made to add corresponding FIB entry, original access
Router updates corresponding FIB entry, and the request message of content provider's situ is then sent to new position.The invention
It in application, needs to rename the content of content provider, there is also the routing table generated due to routing table update polymerizations
Problem.
