Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first" and "second" and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
Fig. 1 is a flowchart of a CDN access method provided in the first embodiment of the present application, where the embodiment may be adapted to avoid access restriction during CDN access, and the method may be performed by a CDN access device, where the device may be implemented by software and/or hardware and specifically configured in an edge node.
Referring to the CDN access method shown in fig. 1, the CDN access method is applied to an edge node, and specifically includes the following steps:
s110, acquiring a CDN access request of a content delivery network for accessing a target website; the CDN access request includes an IP address of the request initiator.
The CDN can be a distributed content distribution network constructed on a data network, can adopt a streaming media server cluster technology, overcomes the defects of insufficient output bandwidth and concurrency capacity of a single-machine system, can improve the number of concurrent flows supported by the system, and reduces or avoids adverse effects caused by single-point failure.
The CDN access request may be a request to access content in a website corresponding to various domain names in the CDN. The target web site may be the domain name of the web site that needs to be accessed. The CDN access request includes the IP address of the request originator.
S120, acquiring accumulated access times of the IP address of the request initiator to each candidate response node.
Each candidate response node may be all edge nodes in the CDN, and configured to respond to the CDN access request, that is, provide a corresponding IP address for the CDN access request, so that the target web address may be accessed through the IP address. The accumulated response times may be a threshold value of the response times of accessing the target website within a preset time, and the preset time may be every second or every minute, etc.
Optionally, the areas set by the different candidate response nodes are different, so that in order to improve the response speed, the CDN sets edge nodes in the different areas as candidate response nodes, so as to quickly respond to CDN access requests in different positions, and improve user experience.
In an alternative embodiment, each candidate responsive node is a public node.
Edge nodes are mainly divided into two forms: private nodes and public nodes. The operating systems of private nodes are typically hp (term, an operating system) embedded operating systems, on which each of these nodes is configured with credentials of its user, which can only be used for a specific domain name. The operating system of the public node is a linux5.X (term, an operating system) operating system, and all public nodes can be configured with a unified certificate, so that websites which randomly use the CDN can be requested by the public nodes, namely, all public nodes can respond to CDN access requests.
Each candidate response node provides a basis for the response of each candidate response node to the CDN access request for the public node.
S130, selecting a target response node from the candidate response nodes according to the accumulated access times so as to access the target website through the target response node.
The target responding node may be an edge node that responds to the CDN access request for providing an IP address for the CDN access request.
There is a rate limiting rule in the CDN, that is, there is an upper limit value for the number of accesses to the same IP address within a preset time, beyond which the IP address is limited to access to the website in the CDN within a certain time. And according to the accumulated access times, taking the candidate response node with smaller corresponding accumulated access times in the candidate response nodes as a target response node so as to access the target website through the target response node.
In the prior art, a rate limiting rule in a CDN is usually handled by means of a proxy pool, for example, 10 servers control a proxy pool, N available IP addresses are in the proxy pool, when a large number of CDN access requests are initiated, once a certain IP address cannot initiate a CDN access request and is limited by the CDN, a new IP address is taken from the proxy pool, and the own server traffic is proxied to the new IP address to continue to initiate the CDN access request.
The proxy pool needs to reserve a large number of IP addresses and guarantee the availability of IP addresses. In addition, there is a certain requirement for the bandwidth of the IP address in the proxy pool. The DDOS initiated restriction is typically that a large number of CDN access requests are sent in a burst-type short time, which requires that the higher the bandwidth upstream capability of the proxy pool, the better, ensuring that traffic passes are unaffected.
The biggest problem of DDOS and DOS at present is that the IP address is easy to be exposed, and is intercepted by the CDN and triggers operations such as restricting the IP address, so that the problem can not last too long, but once the IP address is restricted, the CDN performs risk marking on the IP address and synchronizes in each edge node, and then when the IP is used to request a website protected by the CDN, the restriction threshold is very low, and slightly abnormal request behaviors are restricted, so that the problem that the availability of the IP address in a large number of short-term CDN access request behaviors of the proxy pool IP is low is aggravated.
According to the technical scheme, a CDN access request of a content delivery network for accessing a target website is obtained; the CDN access request comprises an Internet protocol address IP address of a request initiator; acquiring accumulated access times of the IP address of the request initiator to each candidate response node; and selecting a target response node from the candidate response nodes according to the accumulated access times so as to access the target website through the target response node. According to the accumulated access times, the accumulated response times of each candidate response node are determined, so that the target response node is determined, CDN access requests can be averaged to each candidate response node, and access of IP addresses is prevented from being limited because the limit value of CDN access is reached. And a proxy pool is not required to be maintained, so that the maintenance cost is reduced. Therefore, through the technical scheme of the application, the problem that the accessibility of the IP address is greatly reduced once the IP address is limited is solved, and the effect of improving the accessibility of the IP address is achieved.
Example two
Fig. 2 is a flowchart of a flowchart method of a CDN access method provided in a second embodiment of the present application, and the technical solution of the present embodiment is further refined on the basis of the technical solution.
Further, "selecting a target response node from the candidate response nodes according to the accumulated access times", is refined to: and selecting a target response node from the candidate response nodes according to the accumulated access times and the preset access threshold value so as to select the target response node.
Referring to fig. 2, a CDN access method includes:
s210, acquiring a CDN access request of a content delivery network for accessing a target website; the CDN access request includes an IP address of the request originator.
S220, acquiring accumulated access times of the IP address of the request initiator to each candidate response node.
S230, selecting a target response node from the candidate response nodes according to the accumulated access times and the preset access threshold.
The preset access threshold may be an access rate of the IP address of the initiator to be set first, that is, the number of accesses within a preset time, for selecting the target response node. Specifically, a target response node may be selected from the candidate response nodes according to a difference between each accumulated access number and a preset access threshold. For example, selecting the candidate response node with the accumulated access times smaller than the preset access threshold as the target response node.
In an alternative embodiment, the preset access threshold is determined according to a distributed denial of service protocol and/or a denial of service protocol.
The distributed denial of service protocol and the denial of service protocol are used for providing various traffic cleaning services, and are used for screening normal traffic and abnormal traffic, limiting the IP address of the abnormal traffic to be inaccessible after screening the abnormal traffic, and synchronously limiting the IP address to the edge nodes of the global or partial area. Specifically, the preset access threshold may be determined by the distributed denial of service protocol and the minimum value of the restricted access rate in the denial of service protocol.
The preset access threshold is determined according to the distributed denial of service protocol and/or the denial of service protocol, and the preset access threshold can be accurately determined so as to ensure the accuracy of the target response node which is determined according to the accumulated access times and the preset access threshold.
In an alternative embodiment, selecting a target response node from the candidate response nodes according to each accumulated access time and a preset access threshold value includes: determining a difference value according to each accumulated access times and a preset access threshold value; and selecting a target response node from the candidate response nodes according to the difference values.
The difference may be a value obtained by subtracting the accumulated access times from a preset access threshold, and is used to determine the possible response capability of each candidate response node to the IP address, that is, the number of times that the IP address can access each candidate response node in a preset time. If the difference is a positive value, the CDN access request of the IP address to the corresponding candidate response node is not limited, and the larger the value of the difference is positive, the stronger the corresponding response capability of the candidate response node, namely the larger the response frequency. For example, a candidate response node with a difference value of positive values may be selected as the target response node. For example, the target response node may be selected from candidate response nodes with positive differences according to a preset rule. For example, the preset rule may be to sort the differences according to the magnitude relation, and select a candidate response node corresponding to a certain sorted bit difference as the target response node.
Determining a difference value according to each accumulated access times and a preset access threshold value; according to the differences, the target response node is selected from the candidate response nodes, so that the IP address can be prevented from being limited when CDN access requests are carried out through the target response node, the availability of the IP address is guaranteed, and the method is simple in logic and easy to realize.
In an alternative embodiment, selecting a target response node from the candidate response nodes according to the differences includes: and selecting the candidate response node corresponding to the larger value in the difference value as the target response node.
The larger the difference value is, the more times the candidate response node can request the CDN access of the corresponding IP address of the initiator, and the less possibility of being limited. Specifically, the differences may be sorted in order from large to small, and the difference at random or at a specified position in the first M values in the sorting is used as the larger value in the differences. Preferably, the candidate response node corresponding to the maximum value in the difference value is taken as the target response node.
The candidate response node corresponding to the larger value in the difference value is selected as the target response node, so that the corresponding average of each candidate response node to the IP address corresponding to the initiator can be realized, the possibility that the IP address corresponding to the initiator is limited is reduced, and the accessibility of the IP address corresponding to the initiator is improved.
In an alternative embodiment, after selecting the target response node from the candidate response nodes according to the access times and the preset access threshold value to access the target website through the target response node, the method further includes: and updating the accumulated access times corresponding to the target response nodes.
After the target response node is determined, responding to the CDN access request of the IP address corresponding to the initiator through the target response node, and adding 1 to the accumulated access times corresponding to the target response node to update the accumulated access times so as to provide accurate data for the next selection of the target response node.
The real-time performance of each accumulated access frequency is guaranteed by updating the accumulated access frequency corresponding to the target response node, and accurate data is provided for the next selection of the target response node.
According to the technical scheme of the embodiment, the target response node is selected from the candidate response nodes according to the access times and the preset access threshold value, so that the access of the IP address corresponding to the initiator is prevented from being limited due to the limit value, and the accessibility of the IP address is improved.
