Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] figure 1 is a flowchart of a method for adjusting a control strategy according to an embodiment of the present invention. Such as figure 1 As shown, the method may include the following processing steps:

[0028] Step S102: the network service control device acquires current network status information;

[0029] Step S104: The network service control device initiates a control policy adjustment request to the CDN service node according to the obtained current network state information, wherein the control policy adjustment request is used to request the CDN service node to adjust the data flow distributed to users.

[0030] In related technologies, the separation of the CDN system and the c...

Abstract

The invention discloses a control strategy adjustment method and system. The method comprises network service control equipment acquiring the current network state information; and the network service control equipment initializing a control strategy adjustment request to a CDN (content delivery network) service node according to the acquired current network state information, wherein the control strategy adjustment request is used for requesting the CDN service node to adjust the data traffic issued to users. According to the technical scheme, the control strategy adjustment method can prevent over-high acceleration rate of a single user, thereby preventing overuse of the network resources as well as the influences on the network stability and usability, and flexibly adjusting the data traffic issued to the user. The method provided by the invention can also flexibly adjust the user traffic under the network port when congestion possibly occurs at the network port so as to obviate network congestion.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a control strategy adjustment method and system. Background technique [0002] With the rapid development of Internet services, especially the development of video services, service providers need to provide a large number of content delivery network (Content Delivery Network, CDN for short) services to improve the service quality of Internet services. This change has promoted the large-scale use of CDN. [0003] However, since the CDN system in the related art is completely separated from the communication network, the CDN system cannot perceive the state of the communication network. Therefore, the CDN system cannot perceive the state of the network when distributing or accelerating user application content. This makes the CDN application content acceleration not match the network, for example: the current network is already in a congested state, but the CDN system still sen...
