In a practical application scenario, the content distribution system may include different components from the architecture shown in fig. 1, such as more or less components than the architecture shown in fig. 1, and is not limited herein.
The technical solution of the embodiment of the present application provides a node scheduling method based on a content delivery network, and specifically refers to fig. 2. The node scheduling method may be executed by a node scheduling device deployed in the content distribution network, and certainly, may also be executed by other devices in the content distribution network, which is not limited herein. The node scheduling method at least includes steps S100 to S130, which are described in detail as follows:
in step S100, after acquiring the request from the terminal, the IP address of the terminal is acquired from the request to obtain the target IP address.
In the embodiment of the application, in order to obtain the target IP address of the CDN node to be allocated, a request initiated by the terminal may be obtained first, and then the IP address of the terminal is directly obtained from the request, so that the obtained IP address of the terminal is used as the target IP address.
In order to reduce the influence on the existing device, in one example, the request initiated by the terminal may be received by the deployed LDNS device, so that after receiving the request, the LDNS device parses the request to obtain an IP address of a content distribution network corresponding to the request, then returns the IP address of the content distribution network to the terminal by the LDNS device, and then sends the request carrying the IP address of the terminal to the content distribution network corresponding to the request based on the IP address.
In another example, a request initiated by a terminal may be received by a deployed LDNS device, so that the LDNS device, after receiving the request, parses an IP address of a content distribution network corresponding to the request from the request, and then directly adds the IP address of the terminal sending the request in a package manner to the request, that is, the LDNS device may support an EDC (EDCs Client Subnet, a DNS extension protocol for acquiring an IP address of the terminal), so as to acquire an IP address of a visiting terminal in advance. And establishing connection based on the acquired IP address of the content distribution network corresponding to the request and the content distribution network corresponding to the IP address, and then sending the request added with the terminal IP address to the content distribution network.
In step S110, a region corresponding to the target IP address is found from the mapping relationship between the region and the IP address pool, and the found region is used as the target region.
It should be noted that the mapping relationship between the area and the IP address pool is the relationship between a plurality of corresponding IP addresses in a single area and the area after the area is planned according to the partition rule; the division rule can be divided according to a certain area, a certain number or town distribution.
In the embodiment of the present application, in order to determine a target area where a target IP address is located, a connection may be established with a backbone router, a mapping relationship between an area and an IP address pool is obtained from the backbone router based on the connection, an area corresponding to the target IP address is found from the mapping relationship between the area and the IP address pool, and the found area is used as the target area.
In step S120, a target CDN node whose deployment location corresponds to a target area is determined from a plurality of CDN nodes included in the content delivery network.
In the embodiment of the application, in order to determine a target CDN node corresponding to a terminal to which the CDN node is to be allocated, after a target area is obtained, a target CDN node whose deployment location corresponds to the target area may be determined from a plurality of CDN nodes included in a content delivery network.
It should be noted that the deployment location is a service range area corresponding to the CDN node.
The manner of determining the deployment location corresponding to the CDN node may be flexibly set according to actual needs, for example, in an example, the manner may be directly obtained from a content delivery network, that is, the deployment locations of a plurality of CND nodes may be stored in advance in the content delivery network.
In another example, IP addresses of a plurality of CDN nodes included in the content delivery network may be obtained, and then an area corresponding to the IP address of the CDN node is found in a mapping relationship between the area and the IP address pool, so as to determine deployment locations of the plurality of CDN nodes.
Meanwhile, after the deployment positions of the CDN nodes are determined, the deployment positions of the CDN nodes can be compared with the target area one by one, so that the deployment position closest to the target area is determined, and the CDN node corresponding to the deployment position is used as the target CDN node.
In step S130, the target CDN node is scheduled to the terminal, so that the terminal acquires data from the target CDN node.
In the embodiment of the application, after the target CDN node is determined, the target CDN node may be scheduled to the terminal, so that the terminal acquires data from the target CDN node.
The method for scheduling the target CDN node to the terminal may be flexibly set according to actual needs, for example, in an example, the IP address of the target CDN node may be sent to the terminal, so that the terminal may send a connection establishment request to the target CND node after receiving the IP address of the target CDN node, and thus, after the terminal completes connection with the target CDN node, data may be obtained from the target CDN node.
In the above embodiment, an IP address of the terminal is analyzed from an obtained request initiated by the terminal, and the IP address is used as a target IP address, then a target area corresponding to the target IP address is found from a mapping relationship between the area and an IP address pool, where the mapping relationship between the area and the IP address pool is obtained from a backbone router based on connection with the backbone router, then a target area corresponding to the target IP address is found from the mapping relationship between the area and the IP address pool, finally a target CDN node whose deployment location corresponds to the target area is determined from a plurality of CDN nodes included in the content delivery network, and the target CDN node is scheduled to the terminal, so that the terminal obtains data from the target CDN node.
When the area corresponding to the IP address of the terminal is changed, the area corresponding to the IP address of the terminal recorded in the backbone router is also changed correspondingly so as to enable the terminal to be connected to the network, and therefore after the IP address of the terminal is obtained, the corresponding target area after the IP address of the terminal is changed can be found out directly from the mapping relation between the area and the IP address pool based on the connection with the backbone router, compared with a mode of manually updating the area corresponding to the IP address of the terminal recorded at the local terminal, errors are not prone to occurring, and complexity of configuration management is reduced; and then, dispatching and deploying the target CDN node corresponding to the target area for the terminal according to the target area, so that the accuracy of providing service for dispatching the optimal CDN node for the terminal after changing the area is improved, and the service quality is improved.
Referring to fig. 3, fig. 3 is a flow chart illustrating a method for node scheduling based on a content distribution network according to another exemplary embodiment. As shown in fig. 3, before step S110 in the embodiment shown in fig. 2, the method may further include steps S200 to S220, which are described in detail as follows:
in step S200, a connection channel is established with the backbone router through the border gateway protocol.
It should be noted that, after establishing a connection channel based on the border gateway protocol with a router, the border gateway protocol is used to not only interact data with the router through the connection channel, but also periodically send a message for maintaining the connection channel alive.
In this embodiment, a connection channel may be established with the backbone router through the Border Gateway Protocol, that is, a module for establishing a connection channel based on the Border Gateway Protocol may be deployed in advance, where the module includes, but is not limited to, a BGP (Border Gateway Protocol) module deployed in the GSLB device.
In step S210, a routing table stored in the backbone router is acquired through the established connection channel.
The routing table includes a plurality of IP addresses and areas corresponding to the plurality of IP addresses.
In the embodiment of the present application, after a connection channel is established with a backbone router, a routing table stored in the backbone router may be acquired through the connection channel.
In step S220, the obtained routing table is analyzed to obtain a mapping relationship between the area and the IP address pool.
It should be noted first that, in general, a plurality of IP addresses may be set in a single area, that is, a single area may correspond to a plurality of IP addresses.
In the embodiment of the present application, after the routing table is obtained, the routing table may be analyzed, areas corresponding to the plurality of IP addresses and the plurality of IP addresses stored in the routing table are obtained, the plurality of IP addresses are classified according to the areas corresponding to the IP addresses, a relationship between the areas and the plurality of IP addresses is established, and a mapping relationship between the areas and the IP address pool is generated based on the relationship.
Through the embodiment, after the connection channel is established with the backbone router through the border gateway protocol, the routing table stored in the backbone router can be directly obtained through the connection channel, and the routing table does not need to be manually input to the home terminal after the routing table is obtained on the backbone router, so that the complexity of configuration management is reduced.
Referring to fig. 4, fig. 4 is a flowchart illustrating a node scheduling method based on a content distribution network according to another exemplary embodiment. As shown in fig. 4, after step S220 in the embodiment shown in fig. 3, the method may further include steps S300 to S320, which are described in detail as follows:
in step S300, the backbone router is periodically accessed through the connection channel to determine whether a change has occurred in the routing table stored in the backbone router.
It should be noted that, as network services become more popular, IP addresses are often added or deleted at random, and thus, the area divided by the IP addresses may be changed at random.
In this embodiment of the present application, after the mapping relationship between the area and the IP address pool is obtained, the backbone router may be periodically accessed through the connection channel to determine whether the routing table stored in the backbone router is changed.
The method for determining whether the routing table stored in the backbone router changes may be flexibly set according to actual needs, for example, when the backbone router is periodically accessed through a connection channel, the routing table stored in the backbone router is acquired from the backbone router, the latest mapping relationship between the area and the IP address pool is obtained based on the routing table through analysis, then the obtained latest mapping relationship between the area and the IP address pool is compared with the previously obtained mapping relationship between the area and the IP address pool, if there is a difference between the latest mapping relationship between the area and the IP address pool and the previously obtained mapping relationship between the area and the IP address pool, the routing table stored in the backbone router is determined to change, otherwise, the mapping relationship between the area and the IP address pool is not changed.
In step S310, if it is determined that the routing table stored in the backbone router has changed, the latest routing table is acquired from the backbone router.
If the change of the routing table stored in the backbone router is determined, the latest routing table can be obtained from the backbone router through the connecting channel in order to obtain the mapping relation between the latest area and the IP address pool.
In step S320, the mapping relationship between the area and the IP address pool is updated based on the latest acquired routing table.
In the embodiment of the present application, after the latest routing table is acquired, the mapping relationship between the area and the IP address pool may be updated based on the acquired latest routing table.
Through the embodiment, when the routing table stored in the backbone router changes, the new routing table stored in the backbone router can be obtained through the connecting channel, and the mapping relation between the generated area and the IP address pool is re-analyzed, so that the purpose of updating the mapping relation between the area and the IP address pool is achieved, accurate identification is facilitated when the target area corresponding to the IP address of the terminal changes, the precision of scheduling CDN nodes is improved, and the service quality is improved.
Referring to fig. 5, fig. 5 is a flowchart of step S120 in an exemplary embodiment in the embodiment shown in fig. 2. As shown in fig. 4, the process of determining a target CDN node whose deployment location matches a target area from among a plurality of CDN nodes included in a content delivery network may include steps S400 to S420, which are described in detail as follows:
in step S400, IP addresses corresponding to a plurality of CDN nodes included in the content delivery network are acquired.
It should be noted that a plurality of CDN nodes may be deployed in the content delivery network, so as to achieve the purpose of scheduling different CDN nodes for a terminal to provide a service.
In this embodiment, the IP addresses corresponding to the plurality of CDN nodes included in the content delivery network may be directly obtained, that is, the content delivery network may establish communication channels with the plurality of CDN nodes in advance. The communication channel includes, but is not limited to, a wireless signal channel and a wired signal channel.
In step S410, according to the obtained IP addresses corresponding to the plurality of CDN nodes, a region corresponding to each of the plurality of CDN nodes is queried from a mapping relationship between the region and an IP address pool, so as to obtain deployment locations corresponding to the plurality of CDN nodes.
In this embodiment, in order to obtain deployment locations corresponding to a plurality of CDN nodes included in a content delivery network, after obtaining IP addresses corresponding to the plurality of CDN nodes, regions corresponding to the plurality of CDN nodes may be queried from a mapping relationship between the regions and an IP address pool according to the obtained IP addresses corresponding to the plurality of CDN nodes, and the queried regions corresponding to the plurality of CDN nodes may be used as the deployment locations corresponding to the plurality of CDN nodes.
In step S420, a target CDN node whose deployment location matches the target area is determined from the plurality of CDN nodes according to the acquired deployment locations corresponding to the plurality of CDN nodes, respectively.
Since the deployment positions of the plurality of CDN nodes included in the content delivery network may be different positions, the service range of the CDN nodes is expanded.
In an embodiment of the application, after the deployment positions corresponding to the plurality of CDN nodes are obtained, a target CDN node whose deployment position matches a target area may be determined from the plurality of CDN nodes according to the obtained deployment positions corresponding to the plurality of CDN nodes.
For example, in one example, since the deployment positions of the CDN nodes and the target area of the terminal are all obtained from a mapping relationship between an area and an IP address pool by respective IP addresses, the corresponding deployment positions of the CDN nodes and the target area of the terminal may be compared one by one, and if the deployment position of a certain CDN node is the same as the target area of the terminal, the CDN node whose deployment position is the same as the target area of the terminal is used as the target CDN node.
Through the above embodiment, when the content delivery network includes a plurality of CDN nodes and the deployment locations corresponding to the CDN nodes are different, the CDN nodes whose deployment locations are the same as the target area of the terminal may be determined by comparing the deployment locations corresponding to the CDN nodes with the target area of the terminal one by one, and the CDN nodes are used as the target CDN nodes, so as to achieve the purpose of scheduling the target CDN nodes matching the target area from the CDN nodes, thereby improving service quality.
Referring to fig. 6, fig. 6 is a flowchart of step S120 in an exemplary embodiment in the embodiment shown in fig. 2. As shown in fig. 6, the process of determining a target CDN node whose deployment location matches a target area from among a plurality of CDN nodes included in a content delivery network may include steps S500 to S510, which are described in detail as follows:
in step S500, a plurality of candidate CDN nodes whose deployment locations match the target area are determined from among a plurality of CDN nodes included in the content delivery network.
It should be noted that a CDN node of the content delivery network may provide multiple CDN nodes within a single deployment area to serve the terminal.
In this embodiment, a plurality of candidate CDN nodes whose deployment locations match the target area may be determined from a plurality of CDN nodes included in the content delivery network.
The manner of determining the candidate CDN nodes whose deployment locations match the target area may be flexibly set according to actual needs, for example, in an example, the deployment locations corresponding to the CDN nodes may be obtained according to the manner in the foregoing embodiment, the CDN nodes are classified according to the deployment locations, the deployment locations matching the target area are determined, the CDN nodes are determined based on the deployment locations, and the CDN nodes in the deployment locations are all used as the candidate CDN nodes.
In step S510, according to the respective performance parameters of the multiple candidate CDN nodes, a candidate CDN node with the optimal performance is selected from the multiple candidate CDN nodes, and the selected candidate CDN node is used as a target CDN node.
It should be noted that the performance parameter may be used to evaluate the service performance of the CDN node. The performance parameters include, but are not limited to, a load condition of the CDN node, a link state of the CDN node, and the like.

Referring to fig. 7, fig. 7 is a flowchart of step S510 in an exemplary embodiment in the embodiment shown in fig. 6. As shown in fig. 7, the process of selecting a candidate CDN node with the optimal performance from the candidate CDN nodes according to the performance parameters of the candidate CDN nodes may include steps S600 to S610, which are described in detail as follows:
in step S600, load parameters corresponding to the plurality of candidate CDN nodes are obtained, and a CDN node with the smallest load is selected from the plurality of candidate CDN nodes as a CDN node with the best performance according to the obtained load parameters.
It should be noted that the load parameter is the number of terminals currently connected to the CDN node.
In the embodiment of the application, after the plurality of candidate CDN nodes are determined, load parameters corresponding to the plurality of candidate CDN nodes may be obtained, and a CDN node with the minimum load is selected from the plurality of candidate CDN nodes as a CDN node with the optimal performance according to the obtained load parameters.
For example, in one example, when determining the plurality of candidate CDN nodes, requests for obtaining current load parameters may be sent to the plurality of candidate CDN nodes, respectively, so that the plurality of candidate CDN nodes return the current load parameters when receiving the requests, and the returned current load parameters are used as the corresponding load parameters.
In another example, the load parameters corresponding to each of the candidate CDN nodes may be directly obtained from a CDN node database deployed, that is, the CDN node database may establish a communication connection with a plurality of CDN nodes in the content distribution network in advance, and periodically access the plurality of CDN nodes based on the communication connection and obtain the load parameters of the plurality of CDN nodes.
In step S610, link states of the multiple candidate CDN nodes are obtained, and a CDN node in an idle state is selected from the multiple candidate CDN nodes according to the obtained link states as a CDN node with the optimal performance.
It should be noted that the link state is a state of a channel for data exchange with the terminal in the CDN node.
In the embodiment of the application, after the plurality of candidate CDN nodes are determined, link states corresponding to the plurality of candidate CDN nodes may be obtained, and a CDN node in an idle state is selected from the plurality of candidate CDN nodes according to the obtained link states as a CDN node with the optimal performance.
For example, in an example, when determining the plurality of candidate CDN nodes, requests for obtaining a current link state may be sent to the plurality of candidate CDN nodes, respectively, so that the plurality of candidate CDN nodes return the current link state when receiving the requests, and the returned current link state is used as the corresponding link state.
In another example, the link states corresponding to the plurality of candidate CDN nodes may be directly obtained from a CDN node database deployed, that is, the CDN node database may establish a communication connection with the plurality of CDN nodes in the content distribution network in advance, and periodically access the plurality of CDN nodes and obtain the link states of the plurality of CDN nodes based on the communication connection.
The CDN node database may further obtain data stored in the CDN node, that is, after a request sent by the terminal is obtained, target data requested to be obtained by the terminal is analyzed from the request, after a plurality of candidate CDN nodes are determined, storage data corresponding to each of the plurality of CDN nodes is obtained, a candidate CDN node having storage data corresponding to the target data is selected from the plurality of candidate CDN nodes according to the obtained storage data, and the selected candidate CDN node is used as the target CDN node.
Through the above embodiment, after the plurality of candidate CDN nodes are determined, the candidate CDN node with the minimum load and/or the link idle state may be selected as the target CDN node according to the respective corresponding load conditions and/or link states of the plurality of candidate CDN nodes, so that the purpose of invoking the optimal CDN node from the plurality of candidate CDN nodes to provide a service for the terminal is achieved, and the accuracy of invoking the optimal CDN node is further improved.
Referring to fig. 8, fig. 8 is a flowchart illustrating a node scheduling method based on a content distribution network according to another exemplary embodiment. As shown in fig. 8, before step S110 in the embodiment shown in fig. 2, the method may further include steps S700 to S720, which are described in detail as follows:
in step S700, a CDN node corresponding to the target IP address is queried from a mapping relationship between the IP address pool and the CDN node.
It should be noted that the mapping relationship between the IP address pool and the CDN node is established by, after determining a target CDN node whose deployment location matches a target area of the terminal, adding a target CDN node corresponding to a target IP address to the mapping relationship between the area and the IP address pool according to the target IP address.
In the embodiment of the application, after the target IP address of the terminal is obtained, the CDN node corresponding to the target IP address may be queried in a mapping relationship between the IP address pool and the CDN node.
In step S710, if a CDN node corresponding to the target IP address is queried, the queried CDN node is used as the target CDN node.
In the embodiment of the application, in order to reduce the time for determining the target CDN node, in the mapping relationship between the IP address pool and the CDN node, if a CDN node corresponding to the target IP address is queried, the queried CDN node is directly used as the target CDN node.
In step S720, if the CDN node corresponding to the target IP address is not found, the step of finding the region corresponding to the target IP address from the mapping relationship between the region and the IP address pool is performed, and after the target CDN node whose deployment location matches the target region is determined, the target IP address and the corresponding target CDN node are updated to the mapping relationship between the IP address pool and the CDN node.
In the embodiment of the application, if a CDN node corresponding to a target IP address is not found in the mapping relationship between the IP address pool and the CDN node, a target area corresponding to the target IP address is found from the mapping relationship between the area and the IP address pool according to the target IP address, and subsequent steps are performed until a target CDN node whose deployment location matches the target area is determined, and then the target IP address and the corresponding target CDN node are updated to the mapping relationship between the IP address pool and the CDN node.
Through the above embodiment, if a CDN node corresponding to the target IP address is queried in the mapping relationship between the IP address pool and the CDN node, the queried CDN node is used as the target CDN node, thereby reducing the time for scheduling the target CDN node to the target IP address of the terminal. On the contrary, if the CDN node corresponding to the target IP address is not found in the mapping relationship between the IP address pool and the CDN node, after the target CDN node whose deployment location matches the target area is determined, the target IP address and the corresponding target CDN node are updated to the mapping relationship between the IP address pool and the CDN node, so that when the terminal sends the request again, the time for scheduling the CDN node to the terminal is reduced.
