In a preferred embodiment, referring to fig. 1, the website system request traffic control method of this embodiment includes the following steps:
s1, establishing a flow control structure model:
the URL path is cut into a plurality of path elements. Alternatively, the URL path may be split into separate parts by the hierarchical designator, and these separate parts are the path elements. The hierarchy designator here may be, for example, "/" symbols in the URL path used to divide the hierarchy.
And establishing a multi-branch tree structure according to path elements, wherein each URL path is a branch of the multi-branch tree structure, and each path element is a node of the multi-branch tree structure. It should be noted that different URL paths may share at least one node. Optionally, as shown in fig. 2, A, B, C, B, B2, B3, C1 constitute nodes of a multi-way tree structure, and the URL paths are "a/B1", "a/B2", "a/B3", "a/C1".
And setting an access frequency threshold of each node. The access frequency is the cumulative number of accesses per unit time. That is to say, each node counts the number of times that a user access request is matched with a certain node through the access frequency attribute, so that the number of times that a certain webpage is accessed in a certain time period is reflected, and the website system can monitor and judge whether the network is busy or not.
One token bucket is configured for each level of nodes of the multi-way tree structure. It should be noted that each layer of nodes refers to nodes with the same depth from the root node of the multi-way tree structure, which are nodes on the same layer. Specifically, assume that the multi-way tree structure is as shown in fig. 3, node a is assigned token bucket 1 as a single layer, node B and node C are the same layer, shared token bucket 2, nodes B1, B2, B3, and C1 are the same layer, shared token bucket 3, and so on.
S2, token rate adjustment: and monitoring the token acquisition rate of each node, and if the token acquisition rate of each node on the same layer is greater than a first preset proportion of the token generation rate of the token bucket corresponding to the layer, increasing the token generation rate of the token bucket corresponding to the layer. And if the token obtaining rate of each node of the same layer is smaller than the first preset proportion of the token generating rate of the token bucket corresponding to the layer, reducing the token generating rate of the token bucket corresponding to the layer. For example, when the token obtaining rate of each node of the same layer is greater than 50% of the token generation rate of the token bucket of the layer, the token generation rate of the token bucket of the layer is correspondingly increased, and vice versa.
It should be noted that the token acquisition rate refers to the number of tokens acquired by the node in a unit time; the token generation rate refers to the number of tokens generated by the token bucket per unit time. Optionally, an upper and lower limit for the token generation rate of the token bucket may be set.
S3, access frequency adjustment: and monitoring the access frequency of each node, and when the access frequency of a certain node is greater than the access frequency threshold, reducing the access frequency threshold of other nodes on the same layer, and improving the access frequency threshold of the node.
In the embodiment, the rate and the access frequency of the token are monitored and adjusted by combining the multi-branch tree structure and the token bucket algorithm, so that the control and the flow limitation of the network request flow can be realized, the dynamic flexible adjustment of the network resources is realized according to the actual requirements, the problem that the network system is easy to crash when the network access request flow is too high is solved, and the ecological stability of the website system is maintained.
In the website system request traffic management method of some embodiments, the building a multi-way tree structure according to path elements includes:
the path elements form an array according to the front and back sequence, and the array is converted into a multi-branch tree structure; wherein, the front-back sequence is the front-back sequence of the path element in the URL path.
In the embodiment, the path elements form an array according to the front-back sequence in the URL path, so that the traversal sequence is in one-to-one correspondence with the level sequence of the URL path of the user network access request when traversal matching is performed.
In the website system request traffic management and control method according to some embodiments, after the establishing of the traffic management and control structure model, the method further includes the steps of:
and traversing and matching the network access request based on the flow control structure model, waiting for obtaining the token if the matching is successful, and establishing a new node if the matching is not successful. Optionally, when the network access request is traversed and the corresponding matching node cannot be found in the multi-way tree structure, the website system may automatically establish and initialize a new node. Alternatively, when the website has a new webpage, the website system can also automatically perfect and update the multi-way tree structure.
In the embodiment, the network request flow can be managed and controlled and limited, and the network resources can be dynamically and flexibly adjusted according to actual requirements.
In the website system request traffic management method of some embodiments, the traversing and matching network access requests includes:
cutting a URL path of a network access request into a plurality of path elements, forming an array by the path elements according to the front and back sequence, traversing the path elements in the array, and matching with a multi-branch tree structure; wherein, the front-back sequence is the front-back sequence of the path element in the URL path.
In this embodiment, the URL path of the network access request is processed correspondingly and then is matched with the multi-way tree traversal, so that the network request traffic can be managed and controlled and the flow can be limited, and the network resources can be dynamically and flexibly adjusted according to actual requirements.
In the website system request traffic management method of some embodiments, if the matching is successful, waiting for obtaining the token includes:
when traversing and matching a certain node, the node can be called a matching hit node, at this time, the matching hit node tries to obtain the token within the preset time, if the waiting time exceeds the preset time, the network access request is abandoned, and if not, the next layer of node is continuously traversed and matched.

Alternatively, the decreasing of the access frequency threshold of the other node may be decreasing of the access frequency threshold of the at least one other node that meets the condition.
In this embodiment, by monitoring the access frequency of each node and dynamically adjusting the access frequency threshold between nodes on the same layer, not only is the management and control of network request traffic realized, but also network resources, such as the access frequency threshold, can be dynamically and flexibly adjusted according to actual requirements, so that matching hit nodes exceeding a specified threshold are enabled to increase their own threshold by the reduced threshold frequency number of other nodes on the same layer, and the network access request or the next network access request has a chance to obtain a token and access successfully when reaching the matching hit node.
