Compared with the prior art, according to the scheme, the scheduling server can distribute a plurality of content distribution nodes for the terminal according to the state information of the terminal, the terminal selects one node to process data request of the terminal, and the efficiency of the distributing the content distribution nodes is raised.
Description
Technical field
The application relates to networking technology area, relates in particular to a kind of method, system and device of processing terminal dispatch request.
Background technology
Development along with the Internet, in transmission, the unsteadiness in data, the problems such as restriction of transmitted data rates come out in the Internet, the appearance of content distributing network (Content Delivery Network, CDN), has overcome the problems referred to above in internet data transmitting procedure.CDN system, can be in real time according to factors such as the connection of network traffics and server node, loading conditions, and the solicited message that terminal is sent is forwarded on the little server node of load, by this server node, processes request.
CDN system IP based network, through tactic, dispose and build, generally comprise redirected and 4 functions of Content Management of distributed storage, load balancing, network request, wherein, the server cluster that distributed storage forms for storing data in server, and the quantity of server that can extension storage data; Load balancing, refer to that CDN can be according to the loading condition of each node server, by in the node server according to load sequence, the server-assignment of least-loaded is given the terminal sending request, by the request of this terminal of server process of this least-loaded, and then realized being redirected of network request.Content Management is the core of CDN.
Particularly, Fig. 1 is the configuration diagram of CDN network, as shown in Figure 1, CDN system comprises that CDN first node 101, CDN Section Point 102, CDN the 3rd node 103, CDN the 4th node 104, CDN the 5th node 105, these 6 nodes of CDN the 6th node 106(are exemplary, in actual conditions, can there is more node), these 6 nodes are all server node, wherein:
CDN the 4th node 104 is the child node of CDN Section Point 102, and CDN the 5th node 105, CDN the 6th node 106 are the child node of CDN the 3rd node 103.
In practical application, when there are not the data of terminal request in CDN the 4th node 104 and CDN Section Point 102, while there are not these data in definite this locality in first node 101, can obtain data and be stored in this locality from data source 100, by child node, send to CDN the 4th node 104 of direct processing terminal request, in CDN network, the node of other branches can be processed equally.The follow-up CDN node relating to of the application is the node server that terminal can directly be accessed.
CDN structure chart based on shown in Fig. 1, further, CDN system also comprises dispatch server, after the request receiving terminal, according to the loading condition of each node, to terminal distribution node, to realize the node scheduling strategy of load balancing.Wherein, loading condition refers to the task amount of the tasks such as server process request, transmission data.In practical application, this realizes the scheduling strategy of load balancing according to terminal request, main according to the size of node load, to each node sequencing, and after receiving terminal request, the node of present load minimum is distributed to the terminal sending request.
Above-mentioned dispatch server is realized the scheduling strategy of load balancing according to terminal request, only consider self load-factor of node, the actual conditions of having ignored the terminal sending request, the node that causes being dispensed to terminal is not optimal node, thereby has affected node allocative efficiency.

Step 204, dispatch server, according to the state information of confirming, are the CDN node of terminal distribution specified quantity.
In this step 204, the CDN node of specified quantity, can be for determine the CDN node of different priorities according to each CDN node load size, for example, according to load order from small to large, to CDN node sequencing, be arranged in sequence table primary importance for the highest CDN node of priority, i.e. the CDN node of least-loaded.
The nodal information of the CDN node of the specified quantity of step 205, terminal receiving scheduling server-assignment, and from the CDN node distributing, select the request of data of a node processing self.
In this step 205, the CDN node of distributing to terminal is the node of preserving the data of terminal request, preserves data corresponding to Data Identification that terminal sends.Further, terminal can, according to the priority of each node being assigned with, be selected the request of data of the node processing self that priority is the highest.If the failure of node processing terminal request or processing terminal request efficiency that this preferential elder sister is the highest are low, can select priority only lower than the next node of this node, to process the request of data of self, and the priority of a upper node is set to minimum, so, until select the CDN node of normal process terminal request.
So far, the flow process of processing dispatch request finishes.
The flow process of the processing terminal dispatch request that Fig. 2 provides, server can be according to the state of terminal, for this terminal distribution comprises a plurality of CDN nodes of the data of terminal request, then by terminal, from the CDN node being assigned with, selected the request of data of a suitable node processing self, inefficient problem when solving dispatch server and being only a node of terminal distribution according to the load of CDN node, has improved the efficiency of dispatch server distribution node.
Before the step 202 comprising in the flow process shown in Fig. 2, before the dispatch request sending at dispatch server receiving terminal, dispatch server can obtain each CDN node load information, geographical location information and network operator information in CDN system in advance, further, also can obtain the Data Identification information of data and the information of other dispatch servers needs when dispatch server, processing dispatch request that each CDN node is preserved, repeat no longer one by one herein.
Further, in the step 204 that shown in Fig. 2, flow process comprises, be dispatch server according to the state information of confirming, in the step for the CDN node of terminal distribution specified quantity, the present invention also provides an embodiment, particularly, dispatch server, according to the geographical location information of terminal, network operator information, is the CDN node of terminal distribution specified quantity, as shown in Figure 3, the flow process of this dispatch server distribution node, mainly comprises the following steps:
Step 301, dispatch server, according to the network operator information of terminal, are confirmed the CDN node of the Virtual network operator that this network operator information of support is corresponding.
In this step 301, the CDN node of confirming is preserved the data of terminal request, preserves data corresponding to Data Identification that dispatch request that terminal sends comprises.
Step 302, dispatch server be according to the geographical location information of terminal, confirms the CDN node mating with terminal geographic positional information from support the CDN node of above-mentioned Virtual network operator.
In this step 302, the geographical location information of terminal generally comprises the information in country's sign, city/area sign, district/county information and other sign geographical position, dispatch server will be according to above geographical location information, from apart from being in the nearest region of terminal that it selects CDN node, to guarantee that terminal obtains the speed of data.
In the CDN node that step 303, dispatch server are confirmed, CDN node is sorted from small to large according to load, in Selective sequence specified quantity and the preceding CDN node that sorts distribute to described terminal.
This step 303 kind, dispatch server is that terminal is selected after CDN node at network operator information, the geographical location information of integrated terminal, further, can, according to the load of each CDN node from the CDN node of selecting, select the little a plurality of CDN nodes of load and distribute to terminal.
So far, the flow process of dispatch server distribution node finishes.
