The content delivery network (Content Delivery Network, CDN) typically has a plurality of content delivery nodes. When a user requests a resource, a content distribution node which is closer to the user is generally distributed, so that the user can obtain the required resource content nearby, and the response speed of the user for accessing the website is improved.
In the related art, a user source is generally determined based on a Local Domain name server (Local Domain NAME SERVER, LDNS) of the user, and a nearby content distribution node is allocated to the user. In addition, after the content distribution node is distributed to the user, the address of the content distribution node is usually cached in the LDNS of the user, and when the user accesses the same domain name later, the address of the content distribution node cached in the LDNS is directly fed back to the user, so that the same content distribution node is distributed to the user. Thus, when a content distribution node that is first assigned to a user is farther, the user will always be assigned the farther content distribution node later, resulting in a reduced response speed of the user to access the website.

Detailed Description
The present disclosure is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 illustrates an exemplary system architecture 100 of a method for or an apparatus for distributing content distribution nodes to which embodiments of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include terminals 101, 102, 103, networks 104, 105, a target redirect server 106, and content distribution nodes 107, 108, 109. The networks 104, 105 are media to provide communication links between the terminals 101, 102, 103, the target redirect server 106 and the content distribution nodes 107, 108, 109. The networks 104, 105 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
The terminals 101, 102, 103 may interact with the target redirect server 106 through the network 104 to receive or send messages or the like. The terminals 101, 102, 103 may have various applications installed thereon, such as a search class application, a video play class application, a reading class application, and the like.
The terminals 101, 102, 103 may be hardware or software. When the terminals 101, 102, 103 are hardware, they may be various electronic devices supporting the input of content distribution requests, including but not limited to smartphones, tablets, laptop and desktop computers, and the like. When the terminals 101, 102, 103 are software, they can be installed in the above-listed electronic devices. Which may be implemented as multiple software or software modules (e.g., multiple software or software modules for providing distributed services) or as a single software or software module. The present invention is not particularly limited herein.
The target redirect server 106 may be a server providing various services, such as a server determining a content distribution node for responding to the content distribution request sent by the terminals 101, 102, 103. The target redirect server 106 may receive a content distribution request sent by the terminal 101, 102, 103, the content distribution request including a web address and a terminal address of a web page where the requested content is located. Then, for a content distribution node in the content distribution node group (content distribution nodes 107, 108, 109), the content distribution node is determined as a candidate execution node in response to the traffic redundancy value of the content distribution node being greater than a preset redundancy threshold. The traffic redundancy value of the content distribution node is the difference between the current traffic consumption of the content distribution node and the traffic upper limit. And finally, determining the target execution node from the candidate execution nodes based on the terminal address, the node quality parameter of each candidate execution node and the node address of each candidate execution node. The target execution node is used for responding to the content distribution request and feeding back the request content to the terminal based on the website.
The server may be hardware or software. When the server is hardware, the server may be implemented as a distributed server cluster formed by a plurality of servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules (e.g., a plurality of software or software modules for providing distributed services), or as a single software or software module. The present invention is not particularly limited herein.
It should be noted that, the method for distributing content distribution nodes provided by the embodiments of the present disclosure is generally performed by the target redirect server 106, and accordingly, the apparatus for distributing content distribution nodes is generally disposed in the target redirect server 106.
It should be understood that the number of terminals, networks, target redirect servers and content distribution nodes in fig. 1 is merely illustrative. There may be any number of terminals, networks, target redirect servers, and content distribution nodes, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for distributing content distribution nodes according to the present disclosure is shown. The method for distributing content distribution nodes comprises the following steps:
Step 201, a content distribution request sent by a terminal is received.
The content distribution request includes the web address and the terminal address of the web page where the requested content is located.
In this embodiment, an execution body of the method for distributing content distribution nodes (e.g., the target redirect server 106 shown in fig. 1) may receive a content distribution request sent by a terminal through a wired connection or a wireless connection.
The content distribution request comprises a web address and a terminal address of a webpage where the requested content is located. The requested content may include, but is not limited to, text, pictures, audio, video, and the like. The terminal address generally refers to an internet protocol (Internet Protocol, IP) address of the terminal.
It should be noted that the target redirect server is typically a redirect server determined from a group of redirect servers for reassigning the content distribution node to the terminal. Here, the manner in which the target redirect server is determined from the redirect server group may include, but is not limited to, the following. Mode one: randomly selecting a redirect server as a target redirect server. Mode two: the domain name server finds out a redirection server with the address closest to the address of the local domain name server corresponding to the terminal from the redirection server group based on an access request comprising the access domain name sent by the terminal, and the redirection server is used as a target redirection server.
Step 202, for a content distribution node in the content distribution node group, determining the content distribution node as a candidate execution node in response to the traffic redundancy value of the content distribution node being greater than a preset redundancy threshold.
The traffic redundancy value of the content distribution node is the difference between the current traffic consumption of the content distribution node and the traffic upper limit. The current traffic consumption generally refers to a value of traffic consumed by the content distribution node at the current time. The upper traffic limit generally refers to the value of the available traffic of the content distribution node. As an example, for a content distribution node, the upper traffic limit may be 100G and the current traffic consumption may be 80G. At this time, the traffic redundancy value of the content distribution node is 20G. Where G is the flow unit.
In the present embodiment, after receiving the content distribution request, the execution body may determine a candidate execution node from the content distribution node group. Specifically, for any content distribution node in the content distribution node group, the execution body may compare the traffic redundancy value of the content distribution node with a preset redundancy threshold, and if the traffic redundancy value is greater than the preset redundancy threshold, determine the content distribution node as a candidate execution node. Otherwise, if not, the content distribution node is not determined to be a candidate execution node. The preset redundancy threshold may be a preset value.
And 203, determining a target execution node from the candidate execution nodes based on the terminal address, the node quality parameter of each candidate execution node and the node address of each candidate execution node.
The target execution node is used for responding to the content distribution request and feeding back the request content to the terminal based on the website.
The node quality parameter is typically a parameter describing the quality of the node. The node quality parameters may include, but are not limited to, node delay and node availability. Node latency is typically the latency between the area where the terminal address is located and the content distribution node. Node availability generally refers to the amount of capacity a node can provide services. For any content distribution node, the greater the node availability, the greater the capability of the content distribution node to provide services.
In this embodiment, the execution body may acquire the quality parameter and the node address of each candidate execution node. And searching candidate execution nodes with node addresses belonging to the same area as the terminal address from the candidate execution nodes, and if so, continuing to select the candidate execution node with the optimal node quality parameter (for example, the minimum node delay and/or the maximum node availability) from the candidate execution nodes belonging to the same area as the target execution node. If no candidate execution node belonging to the same area is found, the candidate execution node with the optimal node quality parameter (for example, the minimum node delay and/or the maximum node availability) is selected from the candidate execution nodes as the target execution node.
In this embodiment, the execution body may allocate, to the user, the content distribution node having a large traffic redundancy value and a relatively closer address to the terminal address in real time, so as to improve the response speed of the user to access the website while ensuring full utilization of the node traffic resource.
In some optional implementations of this embodiment, the upper traffic limit of the content distribution nodes in the content distribution node group may be determined by an acquiring step, and the acquiring step may include:
In the current computing period, according to a preset flow obtaining interval, obtaining flow consumption of a target user corresponding to the content distribution node, storing the obtained flow consumption into a flow consumption set corresponding to the current computing period, and determining the maximum value in the flow consumption set as the upper flow limit of the content distribution node.
Wherein the calculation period is typically one month and the start point of the calculation period is typically the beginning of one month, e.g. 0 point on day 7 month 1, and the end point of the calculation period is typically the end of the month, e.g. 24 points on day 31 month 7. The flow rate acquisition interval may be a predetermined time interval. As an example, the flow acquisition interval may be 5 minutes.
The target user may be a user who consumes a large amount of traffic of the content distribution node. Or may be a user having a long-term binding relationship with the content distribution node. For a certain content distribution node, the number of corresponding target users can be one or a plurality of. In addition, it should be noted that the above-described flow consumption set is an empty set by default.
In this implementation manner, for each content distribution node, the execution body may acquire, at a predetermined flow acquisition interval, flow consumption of a target user corresponding to the content distribution node. And then, the acquired flow consumption is stored into a flow consumption set corresponding to the current calculation period. Finally, the maximum value in the traffic consumption set is determined as the traffic upper limit of the content distribution node. Here, since one flow consumption is obtained per one flow acquisition interval, the flow consumption set is also newly increased by one element. If the value of the added element is less than or equal to the maximum value in the traffic consumption set before the element is added, the traffic upper limit of the content distribution node is not changed. If the value of the added element is greater than the maximum value in the traffic consumption set before the element is added, the traffic upper limit of the content distribution node is changed to the value of the newly added element. That is, in the present implementation, the upper traffic limit of the content distribution node may be a value that dynamically changes over time.
In the implementation manner, the maximum flow consumption consumed by the content distribution node in the calculation period is always determined as the upper flow limit, so that the demand of a target user on flow resources can be ensured on one hand. On the other hand, the remained flow resources after meeting the demands of the target users can be distributed to other users, so that the effective utilization of the flow resources of the content distribution nodes is realized, and the resource utilization rate is further improved.
In the above implementation, after determining the maximum value in the traffic consumption set as the traffic upper limit of the content distribution node, the obtaining step may further include:
And deleting the minimum value in the flow consumption set in response to the number of flow consumption in the flow consumption set being greater than the preset number.
The predetermined number may be a predetermined data value. As an example, the preset number may be 10, 100, or 432.
In this implementation, only a preset number of traffic consumptions with a larger corresponding value may need to be reserved in the traffic consumption set. The surplus number of traffic consumers with a corresponding small value can therefore be eliminated. This saves storage space.
In some optional implementations of this embodiment, the method for distributing content distribution nodes described above may further include the steps of: determining a required traffic for requesting content and updating the current traffic consumption of the target execution node based on the required traffic.
In this implementation manner, after determining the target execution node for responding to the content distribution request, the execution body may determine the flow required for requesting the content, and then take the sum of the current flow consumption and the required flow as the new current flow consumption of the target execution node. It should be noted that, since the size of the requested content is generally fixed, the required traffic is also fixed, and the required traffic can be obtained directly according to the size of the requested content.
In the implementation manner, the current flow consumption of the target execution node is updated in time, so that accurate distribution of the content distribution node is facilitated, and the response speed of a user for accessing a website is improved while the full utilization of the node flow resource is further ensured.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario 300 of the method for distributing content distribution nodes according to the present embodiment. In the application scenario of fig. 3, a terminal 301 sends a content distribution request to a target redirect server 302. The content distribution request may include a web address M of a web page where the requested content X is located and a terminal address N of the terminal 301.
The target redirect server 302 may, upon receiving the content distribution request, perform the steps of:
First, candidate execution nodes are selected from the content distribution node group { A, B, C, D, E }. Here, for each content distribution node in the content distribution node group { a, B, C, D, E }, the content distribution node is determined as a candidate execution node in response to the traffic redundancy value of the content distribution node being greater than the preset redundancy threshold T. The traffic redundancy value is the difference between the current traffic consumption of the content distribution node and the traffic upper limit. At this time, if the traffic redundancy value of the content distribution node a is 3, the traffic redundancy value of the content distribution node B is 3.5, the traffic redundancy value of the content distribution node C is 1, the traffic redundancy value of the content distribution node D is 2, the traffic redundancy value of the content distribution node E is 0.5, and the preset redundancy threshold T is 2.5. At this time, candidate execution nodes may be screened as follows: a and B.
Then, a target execution node is determined from among the candidate execution nodes a and B. Here, if the distance between the terminal address N and the node address of a is 200 km, the node delay between the area where the terminal address N is located and a is 30 ms and the node availability is 99%. The distance between the terminal address N and the node address of B is 300 km, the node delay between the area where the terminal address N is located and B is 30 ms and the node availability is 96%. At this time, the node address of the candidate execution node a is nearest to the area where the terminal address N is located, and the node quality parameter of a is optimal. The target execution node is a. At this time, the obtained target execution node a may respond to the content distribution request and feed back the request content X to the terminal based on the web address M.
The method for distributing content distribution nodes provided in the foregoing embodiments of the present disclosure may receive a content distribution request sent by a terminal, where the content distribution request includes a web address of a web page where a requested content is located and a terminal address. Then, for a content distribution node in the content distribution node group, the content distribution node is determined as a candidate execution node in response to the traffic redundancy value of the content distribution node being greater than a preset redundancy threshold. The traffic redundancy value of the content distribution node is the difference between the current traffic consumption of the content distribution node and the traffic upper limit. And finally, determining the target execution node from the candidate execution nodes based on the terminal address, the node quality parameter of each candidate execution node and the node address of each candidate execution node. The target execution node is used for responding to the content distribution request and feeding back the request content to the terminal based on the website. The method of the embodiment is not limited by the address of the content distribution node which is allocated for the first time, and can allocate the content distribution node which has large traffic redundancy value and relatively nearer address to the terminal address to the user in real time, thereby improving the response speed of the user for accessing the website while ensuring the full utilization of the node traffic resource.
With further reference to fig. 4, as an implementation of the method shown in the above figures, the present disclosure provides an embodiment of an apparatus for distributing content distribution nodes, which corresponds to the method embodiment shown in fig. 2, and which is particularly applicable in various electronic devices.
As shown in fig. 4, the apparatus 400 for distributing content distribution nodes of the present embodiment includes: a request receiving unit 401 configured to receive a content distribution request sent by a terminal, where the content distribution request includes a web address of a web page where the requested content is located and a terminal address; a candidate determining unit 402 configured to determine, for a content distribution node in the content distribution node group, the content distribution node as a candidate execution node in response to a traffic redundancy value of the content distribution node being greater than a preset redundancy threshold, wherein the traffic redundancy value of the content distribution node is a difference between a current traffic consumption of the content distribution node and an upper traffic limit; and a target determining unit 403 configured to determine a target execution node from the candidate execution nodes based on the terminal address, the node quality parameter of each candidate execution node, and the node address of each candidate execution node, wherein the target execution node is configured to respond to the content distribution request and feed back the requested content to the terminal based on the web address.
In some optional implementations of the present embodiment, in the candidate determining unit 402, the upper traffic limit of the content distribution node in the content distribution node group may be determined by an acquiring step, and the acquiring step may include: in the current computing period, according to a preset flow obtaining interval, obtaining flow consumption of a target user corresponding to the content distribution node, storing the obtained flow consumption into a flow consumption set corresponding to the current computing period, and determining the maximum value in the flow consumption set as the upper flow limit of the content distribution node.
In some optional implementations of this embodiment, after determining the maximum value in the set of traffic consumption as the upper traffic limit of the content distribution node, the obtaining step may further include: and deleting the minimum value in the flow consumption set in response to the number of flow consumption in the flow consumption set being greater than the preset number.
In some alternative implementations of the present embodiment, the apparatus may further include a traffic update unit (not shown in the figure). The traffic update unit may be configured to: determining a required traffic for requesting content and updating the current traffic consumption of the target execution node based on the required traffic.
In the apparatus provided in the foregoing embodiment of the present disclosure, the request receiving unit 401 receives a content distribution request sent by a terminal, where the content distribution request includes a web address of a web page where the requested content is located and a terminal address. Then, the candidate determination unit 402 determines, for a content distribution node in the content distribution node group, the content distribution node as a candidate execution node in response to the traffic redundancy value of the content distribution node being greater than a preset redundancy threshold. The traffic redundancy value of the content distribution node is the difference between the current traffic consumption of the content distribution node and the traffic upper limit. Finally, the target determination unit 403 determines the target execution node from among the candidate execution nodes based on the terminal address, the node quality parameter of each candidate execution node, and the node address of each candidate execution node. The target execution node is used for responding to the content distribution request and feeding back the request content to the terminal based on the website. The device of the embodiment is not limited by the address of the content distribution node allocated for the first time, and can allocate the content distribution node with large traffic redundancy value and relatively closer address to the terminal address to the user in real time, thereby improving the response speed of the user for accessing the website while ensuring the full utilization of the node traffic resource.

Wherein the target redirect server 5011 is configured to perform the method shown in fig. 2 to determine a target execution node 5021 from the content distribution node group 502.
The target execution node 5021 is configured to: responding to a content distribution request sent by the terminal, and feeding back the request content to the terminal based on the website in the content distribution request.
The system for distributing the content distribution nodes, which is provided by the embodiment of the invention, is not limited by the address of the content distribution node which is distributed for the first time, and can distribute the content distribution node with large traffic redundancy value and relatively closer address to the terminal address to the user in real time, thereby realizing the purpose of ensuring the full utilization of the traffic resource of the node and improving the response speed of the user for accessing the website.
In some alternative implementations of the present embodiment, the system for assigning content distribution nodes may further include a domain name server. Wherein the domain name server is used for executing the following steps:
first, an access request including an access domain name is received from a terminal.
Here, the domain name server may receive an access request transmitted from the terminal through the network. Wherein, the access request includes an access domain name.
And secondly, determining a redirection server from the redirection server group as a target redirection server according to the access domain name and the address of the local domain name server corresponding to the terminal.
Here, if the local domain name server corresponding to the terminal has the address of the redirect server corresponding to the access domain name cached therein, the domain name server may directly determine the redirect server corresponding to the cached address of the redirect server as the target redirect server. In addition, if the address of the redirect server corresponding to the access domain name is not cached in the local domain name server corresponding to the terminal, the domain name server may parse the access domain name, and determine, from the redirect server group, a redirect server close to the address of the local domain name server corresponding to the terminal as the target redirect server. And correspondingly caching the obtained address of the target redirection server and the access domain name.
And thirdly, sending the address of the target redirection server to the terminal so that the terminal sends a content distribution request to the target redirection server based on the address of the target redirection server.
Here, the domain name server may transmit the obtained address of the target redirect server to the terminal through the network. In this way, the terminal can send a content distribution request to the target redirect server through the address of the target redirect server.
In the implementation manner, the domain name server determines the redirection server from the redirection server group as the target redirection server, so that the target redirection server belonging to the same area as the terminal can be obtained, and the target redirection server can process the content distribution request sent by the terminal more quickly, thereby further improving the response speed of the user for accessing the website.
