If the match is successful, the request data package is the packet of other purposes, performs step 103.
In step 103, extend and accelerate node to refuse the request data package response.
At step 104, extend and accelerate node to accelerate function for user carries by the content of itself
Accelerate to service for content.
In the prior art, Akamai companies propose that content distributing network is expanded to movement by one kind
Or the method for cable network：In a content requests of user, " expander " as towards
The exclusive node of terminal service, no matter whether content hits, all provides service, together by expander
When want superior CDN request contents method of service indicate.Under this kind of pattern, expander with it is upper
Need to formulate more complete interactive interface between level CDN, as expander health degree, bear
Between the information exchange of the aspects such as load situation, content caching, therefore expander and higher level CDN
Can not decouple, it is necessary to both sides' software is upgraded and docked.
And pass through the method for the present invention, extend the packet for accelerating node to obtain user's transmission
Duplicate, by the target ip address of packet judge user to accelerate service node ask in
Hold and accelerate service, and then accelerate node directly to provide the user content by extension and accelerate service, from

If the match is successful, the request data package is the packet of other purposes, performs step 205.
In step 203, the content of user's request in acclerating section point analysis request data package is extended,
Judge that node hit can be accelerated in this extension.If can hit, step 204 is performed；If
Can not hit, then perform step 205.
In step 204, extend and accelerate node to accelerate function for user carries by the content of itself
Accelerate to service for content.
In step 205, extend and accelerate node to refuse the request data package response.
In the method, extend and accelerate node after judging that user's request content accelerates service, meeting is first
Can judgement provide a user with the content, when that can provide content acceleration service, then by certainly
Body provides content and accelerates service, and when that can not provide service, user's request still can be by Target IP
The acceleration service node of address is responded and provides service, so as to avoid having influence on user's acquisition request
Content.
In one embodiment, when extension accelerates node to determine to be added by itself providing a user with content
After speed service, service termination request can be sent to the target ip address of request data package, inform use
The content of family request accelerates service node to stop providing the user content acceleration service.In the method,
Extend the raw content server node for accelerating node timely to prevent user's request to be sent out to user
Content is sent, prevents user from receiving double content, increase unnecessary flow consumption.
The flow chart of another embodiment of present disclosure accelerated method is as shown in Figure 3.
In step 301, when terminal initiates access to content, can be initiated to access scheduling system
Content access request.
In step 302, terminal is obtained from the acceleration service node of access scheduling system acquisition
IP address, and sent to corresponding acceleration service node as target ip address using the IP address
It is required that content accelerates the request data package of service.
In step 303, the duplicate for accelerating node to obtain the request data package that user sends is extended.
In step 304, extend accelerate node according to the target ip address of request data package with
The IP address of service node is accelerated to be matched.Extend and accelerate node to be configured with acceleration service node
IP address.If the match is successful, illustrate the request data package for user to accelerate service node
Request content accelerates the packet of service, performs step 305；If the match is successful, should
The packet that packet is other purposes is sought, step 307 is performed.
In step 305, the content of user's request in acclerating section point analysis request data package is extended,
Judge that node hit can be accelerated in this extension.If can hit, step 306 is performed；If
Can not hit, then perform step 307.
Within step 306, extend and accelerate node to accelerate function for user carries by the content of itself
Accelerate to service for content.
In step 307, extend and accelerate node to refuse the request data package response.
The method can by existing terminal to access scheduling system initiate content access request with
Of the invention extension accelerates the scheme of node to be combined, and extends and accelerates node to accelerate system with raw content
System concurrent working, develops without docking；Ensure to extend and accelerate node to accelerate node two with raw content

By some contents accelerate server group into.Can include by operator deployment in non-public network
And the extension for providing accelerates node.Extending acceleration node can independently dispose and run, and realize interior
Hold and accelerate；Can also be in non-public network instead of the acceleration service node of raw content acceleration system
Realize that it extends the purpose for accelerating.Because the extension in non-public network accelerates node without right
The IP address or open port that can be openly route in internet, therefore raw content acceleration system
Operation center need not monitor it, i.e., it is unnecessary to extend acclerating section point carry out service mode configuration,
The operations such as node health is checked, content caching distribution.Extend and accelerate node with parallel way portion
Administration in customer access pipe, and user accesses still by the scheduling according to raw content acceleration system or
Diversion mode points to the acceleration service node of raw content acceleration system, therefore extends acceleration node event

In 502, terminal is to access scheduling or flow guide system transmission content access request.
In 503, access scheduling or flow guide system are returned to user according to former strategy and accelerate service
The IP address of node.
In 504, terminal sends request data package, the request data package to acceleration service node
By way of the optical splitting point for extending acceleration node, it is extended and accelerates node synchronously to obtain.
In 505, extend the purpose IP address of acclerating section point analysis packet, find and this
Node extends and accelerates target ip address matching, judges that the request content belongs to extension acceleration range.
In 506, extend acclerating section point analysis user's request content and hit in this node, this section
Point can provide the user content and accelerate service.
In 507, extend and accelerate node to the correct response of terminal replies, there is provided content service,
Accelerate node to send TCP RST to raw content simultaneously to ask, terminate raw content and accelerate service section
Point provides a user with service.
In the method, the access scheduling or flow guide system of raw content acceleration system need not know to extend
Accelerate the presence of node, for the extension node will not be accelerated to dispatch, and then can support different
Structure node cooperative work；The network site of node is accelerated to accelerate network than raw content due to extending
Accelerate service node closer to user terminal, therefore on logic corresponding relation, be multiple extensions
Node one raw content of correspondence is accelerated to accelerate network node, it is generally the case that raw content accelerates net
Network node externally provides a VIP address for local load balancing equipment, and extension accelerates in node
It is pre-configured with this VIP address；Or content accelerate network node multiple is externally provided can
The IP address of access, then extending acceleration node can all be configured to these IP address extend acceleration
Target IP.
In one embodiment, such as in order to the distribution of content is paid the fees to CDN service business, then
Extending acceleration node needs to provide service related data to CDN；Or in order to improve security,
Former acceleration system carries out security verification to extending acclerating section point.In above-mentioned necessary feelings between them

Certain converge ring on, carry out content acceleration for the mobile terminal under multiple base stations.Extend section
The extension of point 1 accelerates Target IP to be preconfigured to be the IP ground that CDN accelerates service node 1
Location.The access request of UE is dispatched to CDN and adds by the CDN GSLB disposed on fixed network first
On fast service node 1, then UE accelerates service node to initiate HTTP request to the CDN,
Extend and accelerate node to obtain this request by spectroscopic modes, and judge that the request purpose IP address are
Whether the no IP address to accelerate service node, content hits.As content hit if directly to
UE provides service, and accelerates node 1 to initiate TCP RST instructions to CDN, and CDN accelerates
Node 1 does not provide service to UE.As content is miss, then extend 1 pair of request of node not
Response is given, user's request normally reaches CDN and accelerates service node 1, accelerated to service by CDN
Node 1 provides service, so that ensure to extend accelerate node and raw content acceleration system concurrent working,
Extend and accelerate node or accelerate both service nodes one for Terminal for service, and extension accelerates
