monitoring the change of the priority identification of the target streaming media data; and adjusting the priority of the forwarding task queue according to the change of the priority identification of the target streaming media data. When the client level corresponding to the corresponding target streaming media data becomes the highest level or the corresponding real-time flow increases rapidly, the priority of the forwarding task queue can be adjusted through the change of the priority identification of the target streaming media data, so that the priority of the forwarding task queue can be adjusted in real time to avoid the heat flow client using the link with poor link quality.
Fig. 5 is an optional schematic flow chart of the network resource allocation adjustment method according to the embodiment of the present disclosure, where the network resource allocation adjustment method is implemented by a processor CPU of a content distribution network streaming media server, and the type of the streaming media data is live video streaming media data. As shown in fig. 5, an optional process of the network resource configuration adjustment method provided in the embodiment of the present disclosure includes the following steps:
step 501: different channels of the M live broadcast websites A are used for playing the streaming media data A (stream _ A), and a streaming media data playing request A is sent to the CDN streaming media server.

1) the distribution mode is not flexible enough and is fixed. Differentiated services aiming at different customers are planned from the node and equipment level, communication with the customers needs to be carried out in the early stage, and the communication is good in magnitude before the customer is maximized. Once the service is started, it is difficult to make adjustments in a short time. If the playing amount of the predetermined streaming media data of the client does not reach the expectation, the resources are wasted.
2) When the link is maintained, the use state of the client needs to be estimated in advance, so that the link is difficult to maintain.
3) The link is expensive to use, and the CDN needs to invest resources that are much higher than the actual cost of occurrence because its differentiated service allocation is not flexible enough. For example, to devote a group of independent devices to a customer, which once allocated means that the several machines cannot serve other customers. For the original customer service, additional costs are required.
Step 502: and different channels of the N B live broadcast websites send streaming media data playing requests to the CDN streaming media server for playing the streaming media data B (stream _ B).

For the same live broadcast website a, the link qualities required by M different live broadcast channels are different, wherein a link with the highest link quality is required for a hot-flow live broadcast channel as a client, and conversely, a link with the highest link quality is not required for a cold-flow live broadcast channel as a client, so that the live broadcast video can be played.
Step 5053: creating a forwarding task for the corresponding customer and adding the created forwarding task to the third priority queue.
Optionally, the client priority may be divided into a first priority, a second priority and a third priority in sequence from high to low, and the priority queue corresponding to the corresponding created forwarding task may be marked as: a first priority queue, a second priority queue, and a third priority queue. In the network resource adjustment process, a link with the highest link quality may be configured for the forwarding task in the first priority queue with the highest priority, so as to ensure that the network resource configuration is adapted to the priority of the target streaming media data.
Step 5054: it is determined whether streaming media data a corresponds to the highest priority client, if so, step 5055 is performed, otherwise, step 5056 is performed.
Step 5055: a forwarding task is created for the corresponding customer and the created forwarding task is added to the first priority queue.
Step 5056: creating a forwarding task for the corresponding customer and adding the created forwarding task to the second priority queue.
Step 506: and after receiving the stream media data B of the stream _ B, the CDN stream media server creates a forwarding task according to the priority of the client B corresponding to the stream _ B.
Wherein if client B has a lower priority, N forwarding tasks will be created and placed in the corresponding normal priority queue.
Step 507: and comparing the priorities of the client A and the client B, and preferentially executing the M forwarding tasks in the forwarding task queue corresponding to the client A when the priority of the client A is higher than that of the client B.
Step 508: when processing the forwarding task queues with different priorities, the CDN streaming media server processes the tasks in the forwarding task queue with a high priority first, and processes the tasks in the forwarding task queue with a low priority after the tasks in the forwarding task queue with a high priority are processed.
Fig. 8 is an optional flowchart illustrating that the CDN streaming media server processes forwarding task queues with different priorities in the embodiment of the present disclosure, where a priority queue corresponding to a created forwarding task may be marked as: the priority of the first priority queue, the priority of the second priority queue and the priority of the third priority queue are reduced in sequence. The CDN streaming media server processing the forwarding task queues with different priorities comprises the following steps:
step 5081: starting to traverse all the forwarding task queues;
step 5082: it is determined whether the forwarding task queue with the highest priority (the first priority queue) is empty, if so, step 5084 is performed, otherwise, step 5083 is performed.
Step 5083: and configuring the link with the highest link quality in the network resources for the forwarding task queue with the highest priority.
And the link with the highest link quality in the network resources can not provide data transmission service for other forwarding task queues until all the forwarding tasks in the forwarding task queues are completed.
Step 5084: a determination is made as to whether the second priority queue is empty, if so, step 5086 is performed, otherwise, step 5085 is performed.
Step 5085: and configuring a corresponding link in the network resource according to the second priority of the target streaming media data in the task queue.
