Based on the system architecture diagram shown in fig. 1, an embodiment of the present application provides a flow of a bandwidth control method, as shown in fig. 2, where the flow of the method is executed by an edge proxy device, and includes the following steps:
in step S201, the edge proxy device obtains bandwidth configuration information and bandwidth data of the target channel in the previous decision period.
Specifically, the bandwidth configuration information may be any one or more of a process anti-burst ratio, a process group anti-burst ratio, a central decision task threshold, a bandwidth recovery step size, and a bandwidth recovery period, and the bandwidth configuration information is configured by an operation and maintenance worker through the configuration central device. In a specific implementation, different bandwidth configuration information may be configured for different client channels, and the target channel may be any one of the client channels. Each customer channel corresponds to an edge process group in the edge resource device, and one edge process group comprises a plurality of edge processes.
Step S202, when determining that the central control policy of the target channel is not generated by the decision center device, the edge proxy device generates an edge control policy of the target channel according to the bandwidth configuration information and the bandwidth data of the target channel in the previous decision period.
Specifically, the edge control policy of the target channel includes a bandwidth control threshold of an edge process corresponding to the target channel, where the bandwidth control threshold may be a fixed value determined by the edge proxy device, or a real-time changing value determined according to bandwidth data in a previous decision period.
In step S203, the edge proxy device sends the edge control policy of the target channel to the edge resource device.
In the embodiment of the application, because the edge proxy device generates the edge control policy and issues the edge control policy to the edge resource device when the decision center device does not generate the center control policy, the method for issuing the edge control policy before the bandwidth value of the customer channel does not reach the control threshold can effectively solve the problem of central decision hysteresis, avoid sudden bandwidth increase, and thus can effectively protect the service of the CDN platform and each customer.
Optionally, in step S202, the bandwidth configuration information includes a process burst prevention ratio, a process group burst prevention ratio, and a central decision task threshold, and the edge control policy of the target channel includes a bandwidth control threshold of an edge process corresponding to the target channel. When generating an edge control policy of a target channel according to bandwidth configuration information and bandwidth data of the target channel, embodiments of the present application provide at least the following implementation manners:
in the first embodiment, for any target edge process in a target edge process group corresponding to a target channel, when bandwidth data of the target channel is not acquired from the target edge process in a previous decision period, the edge proxy device generates a bandwidth control threshold of the target edge process according to a process anti-burst ratio and a central decision task threshold. When the bandwidth data of the target channel is acquired from the target edge process in the last decision period, the edge proxy equipment generates the bandwidth control threshold of the target edge process according to the outburst prevention proportion of the process group, the central decision task threshold, and the bandwidth data of the target channel acquired from the target edge process and the target edge process group in the last decision period.
Specifically, when the bandwidth data of the target channel is not collected from the target edge process in the previous decision period, it indicates that the target edge process has not processed the service of the target channel in the previous decision period, and at this time, the bandwidth control threshold may be set to a fixed value. In specific implementation, the product of the process anti-burst ratio and the central decision task threshold may be used as a bandwidth control threshold of the target edge process, which is specifically shown in the following formula (1):
F＝Q*C………………………………………(1)
wherein Q is the process outburst prevention ratio, C is the central decision task threshold, and F is the bandwidth control threshold of the target edge process.
When the bandwidth data of the target channel is acquired from the target edge process in the previous decision period, it is indicated that the target edge process processes the service of the target channel in the previous decision period, and at this time, the bandwidth control threshold of the target edge process may be determined according to the bandwidth data acquired in real time, which is specifically shown in the following formula (2):
W＝P*C*r i /∑(r i )…………………………………(2)
wherein, P is the burst-preventing proportion of the process group, C is the threshold of the central decision task, r is the bandwidth of the target channel collected from the target edge process i in the last decision period, sigma (r) i ) The bandwidth of the target channel collected from the target edge process group in the last decision period.
When the target channel bandwidth does not exist in the target edge process, the bandwidth control threshold of the target edge process is determined based on the bandwidth configuration information, so that the sudden increase of the bandwidth of the edge process from nothing to nothing is avoided. When the target edge process has the target channel bandwidth, the bandwidth control threshold of the target edge process is determined based on the bandwidth configuration information and the target channel bandwidth, so that normal processing of the target channel service is ensured, and influence on other client channels caused by rapid increase of the target channel bandwidth is avoided.
And in the second implementation mode, aiming at any one target edge process in the target edge process group corresponding to the target channel, the edge proxy equipment generates the bandwidth control threshold of the target edge process according to the process outburst prevention proportion and the central decision task threshold.
In specific implementation, the product of the process anti-burst ratio and the central decision task threshold is used as the bandwidth control threshold of the target edge process, which is specifically shown in the above formula (1).
In the embodiment of the application, the bandwidth control threshold of the target edge process is determined based on the bandwidth configuration information, so that sudden increase of the bandwidth of the edge process from nothing to nothing is avoided.
On the basis of any one of the two embodiments, the edge proxy device sends the bandwidth control threshold of the target edge process to the target edge process in the edge resource device, so that when the target edge process receives a service request of a user, the bandwidth can be controlled below the bandwidth control threshold, thereby effectively protecting the service of the CDN platform and each customer. And sending the bandwidth control threshold of the target edge process to the target edge process in the edge resource device, thereby realizing the process-level bandwidth control in the edge resource device.
Optionally, when determining that the central control policy of the target channel exists in the decision center device, the edge proxy device generates the edge control policy in at least the following two ways:
in the first embodiment, for any target edge process in a target edge process group corresponding to a target channel, when bandwidth data of the target channel is not acquired from the target edge process in a previous decision period, an edge control policy of the target channel is generated according to bandwidth configuration information. And when the bandwidth data of the target channel is acquired from the target edge process in the last decision period, generating an edge control strategy of the target channel according to the bandwidth configuration information, the bandwidth data of the target channel acquired from the target edge process group in the last decision period and the central control strategy.
Specifically, when the bandwidth data of the target channel is not acquired from the target edge process in the previous decision period, it is indicated that the target edge process has not processed the service of the target channel in the previous decision period, and at this time, a fixed bandwidth control threshold may be issued as the edge control policy. In specific implementation, the bandwidth control threshold of the target edge process may be generated according to the process anti-burst ratio and the central decision task threshold, which is specifically shown in the above formula (1).
When the bandwidth data of the target channel is collected from the target edge process in the previous decision period, it is indicated that the target edge process processes the traffic of the target channel in the previous decision period. At this time, the decision center device also issues a central control policy of the target channel, and may generate the edge control policy of the target channel according to the bandwidth configuration information, the bandwidth data of the target channel acquired from the target edge process group in the previous decision period, and the central control policy, where the central control policy of the target channel is generated by the decision center device according to the bandwidth data and the bandwidth configuration information of the target channel in the previous decision period. In specific implementation, the decision center device summarizes the full-network bandwidth data of the client channels reported by each edge proxy device, and then generates a central control policy of the target channel based on the full-network bandwidth data, the historical central control policy, the bandwidth data of the target channel collected from the target edge process group in the previous decision period, and the bandwidth configuration information.
In the embodiment of the application, when a central control strategy of a target channel exists in the decision center equipment and bandwidth data of the target channel does not exist in the edge process of the target channel in the last decision period, the edge control strategy of the target channel is generated based on the bandwidth configuration information, so that sudden increase of the bandwidth of the edge process of the target channel from nothing to nothing is avoided. When a central control strategy of a target channel exists in the decision center equipment and bandwidth data of the target channel exists in the edge process of the target channel in the last decision period, the edge control strategy of the target channel is generated by combining the central control strategy and the bandwidth data of the target channel, so that bandwidth allocation is matched with the actual network operation condition, and the utilization rate of network resources is improved.
And in the second implementation mode, aiming at any target edge process in the target edge process group corresponding to the target channel, generating an edge control strategy of the target channel according to the bandwidth configuration information, the bandwidth data of the target channel collected from the target edge process group in the last decision period and the central control strategy.
In specific implementation, the decision center device summarizes bandwidth data of the client channels reported by each edge proxy device to obtain bandwidth data of the whole network, and then generates a central control strategy of the target channel based on the bandwidth data of the whole network, a historical central control strategy, the bandwidth data of the target channel collected from the target edge process group in the previous decision period, and bandwidth configuration information. The decision center equipment sends the center control strategy of the target channel to the edge proxy equipment, and the edge proxy equipment generates the edge control strategy of the target channel according to the bandwidth configuration information, the bandwidth data of the target channel collected from the target edge process group in the last decision period and the center control strategy and sends the edge control strategy of the target channel to the target edge process in the edge resource equipment.
In the embodiment of the application, when a central control strategy of a target channel exists in the decision center equipment, an edge control strategy of the target channel is generated by combining the central control strategy and bandwidth data of the target channel, so that bandwidth allocation is matched with the actual network operation condition, and the utilization rate of network resources is improved.
Optionally, the edge proxy device receives a bandwidth recovery policy of a target channel sent by the decision center device, where the bandwidth recovery policy of the target channel is generated by the decision center device when determining that a bandwidth value of the target channel is smaller than a release control threshold, and then sends the bandwidth recovery policy of the target channel to an edge process corresponding to the target channel in the edge resource device.
Specifically, when a decision period arrives, the decision center device first determines whether a central control policy of a target channel is issued, and when the decision center device has issued the central control policy of the target channel, determines a bandwidth value of the target channel according to bandwidth data of the target channel in a previous decision period, and then further determines whether the bandwidth value of the target channel is smaller than a de-control threshold, and if so, generates a bandwidth recovery policy of the target channel. Otherwise, generating a central control strategy of the target channel according to the bandwidth data and the bandwidth configuration information of the target channel in the last decision period.
When the decision center device does not issue the central control strategy of the target channel, firstly, whether the bandwidth value of the target channel is greater than the central decision task threshold is judged, if yes, the central control strategy of the target channel is generated according to the bandwidth data and the bandwidth configuration information of the target channel in the last decision period, and if not, the central control strategy waits for the next decision period.
In the embodiment of the application, the decision center device generates a bandwidth recovery strategy when determining that the bandwidth value of the target channel is smaller than the release control threshold value, and sends the bandwidth recovery strategy to the edge process corresponding to the target channel through the edge proxy device. The control of the central control strategy is gradually released through the bandwidth recovery strategy, and the repeated sudden increase and sudden decrease of the bandwidth are effectively avoided.
The bandwidth recovery strategy of the target channel is determined by the decision center equipment according to the bandwidth recovery step length, the bandwidth recovery period and the bandwidth data of the target channel in the last decision period.
Specifically, the bandwidth recovery policy of the target channel includes a bandwidth recovery ratio within a decision period. The bandwidth recovery step represents a bandwidth recovery ratio in unit time, a bandwidth recovery period is a total time required for recovering the bandwidth to a preset value, and the bandwidth recovery ratio in a decision period is specifically shown in the following formula (3):
M＝T*N…………………………………(3)
wherein, M represents the bandwidth recovery ratio in the decision period, T represents the bandwidth recovery duration in the decision period, and N represents the bandwidth recovery step size.
In specific implementation, it may be required to go through multiple decision periods when the bandwidth of the target channel is restored to the preset value, that is, the bandwidth restoration period corresponds to multiple decision periods, and the bandwidth restoration ratio in each decision period may be the same, or may be adjusted in real time based on the bandwidth data of the target channel in the last decision period. For example, when the bandwidth data of the target channel in the previous decision period gradually becomes stable, the bandwidth recovery ratio in the decision period is increased, and specifically, the bandwidth recovery step size or the bandwidth recovery duration in the decision period may be increased, so as to increase the bandwidth recovery speed and shorten the bandwidth recovery period. By gradually releasing the bandwidth control, the bandwidth of the channel of the client is released completely after the bandwidth tends to be stable, thereby effectively avoiding the repeated sudden increase and sudden decrease of the bandwidth.
To better explain the embodiment of the present application, a bandwidth control method provided by the embodiment of the present application is introduced below with reference to a specific system architecture, and as shown in fig. 3, the system architecture includes a configuration center device, a database, a configuration data distribution device, a decision center device, an edge proxy device, and an edge resource device.
The decision center equipment comprises a configuration data loading module, an agent data acquisition module, a decision module and a strategy issuing module.

And the operation and maintenance personnel add the bandwidth configuration information through the configuration center equipment, store the bandwidth configuration information into the database and send the bandwidth configuration information to the configuration data distribution equipment. And the decision center equipment and the edge proxy equipment pull the bandwidth configuration information from the configuration data distribution equipment. And the decision center equipment performs central decision according to the bandwidth data of the client channel reported by the edge agent equipment and the bandwidth configuration information of the configuration center equipment to obtain a central control strategy and transmits the central control strategy to the edge agent equipment. And the edge agent equipment carries out edge decision according to the bandwidth configuration information for configuring the central equipment, the central control strategy and the bandwidth data of the client channel to obtain an edge control strategy and sends the edge control strategy to an edge process in the edge resource equipment.
The following describes the flow of the decision center device performing the central decision and the edge agent device performing the edge decision.
