In embodiments of the present invention, at normal state, when log on was accelerated under the content conditions of support, based on network state, user's network connection state, user's application downloading rate, user's the information such as flow use were carried out access control to the user; In the content conditions of support, under content and network joint protection state, according to the state of network, user's application downloading rate etc. are adjusted user's content acceleration to the user.Use to reach Optimizing Network Resources, ensure network stabilization, at utmost ensure the target of quality of service.

The below is being described at the strategy of speed control of application layer with in the method for adjustment of the strategy of speed control of network layer the embodiment of the invention respectively.

Figure 11 is the flow chart according to the control method of the user network acceleration strategy of the embodiment of the invention three, and as shown in figure 11, the method comprises that mainly step S1102 is to step S1118.

Step S1102, main control unit issues corresponding control strategy to network components.

In embodiments of the present invention, main control unit issues the network acceleration constraints policy to network components, and specific strategy can customize as required.

For example, the high-grade application bandwidth accounting of user place port reaches A% (supposing A%=60%), then no longer admits the user network acceleration request; Purpose is the quality that ensures the high-grade application of network, also ensures the quality that other are professional, avoids owing to admit New Consumers to accelerate the network congestion that brings; User place port bandwidth utilance reaches B% (supposing B%=90%), then no longer admits the user network acceleration request, avoids owing to admit New Consumers to accelerate the network congestion that brings; The downloading rate that user's current network connects has reached C bit/s(hypothesis C=50M), then no longer admit this user network acceleration request, avoid sole user's network rate too high; The flow of this network connection of user has reached D GB (supposing D=10), then no longer admits this user's network acceleration request, avoids the sole user excessively to use network.

Step S1104, after network strategy issued execution, network components sent the network acceleration constraints policy to main control unit and carries out feedback information.

Network components can retrain and control according to the network acceleration request of strategy to the user after receiving network acceleration constraints policy and successful execution.

Step S1106, the CDN parts are to the network acceleration request of network components initiation for the user.

After network components was received user's network acceleration request, execution in step S1108 was to step S1118.

Step S1108, the inquiring user state, as inquire about failure, then abandon this acceleration request; If correctly inquire user's network state, enter step S1110.

Step S1110, the bandwidth that the high-grade application of inquiring user place port takies, reach port total bandwidth A% such as the bandwidth accounting, the then network acceleration request of refusing user's, and returning the network acceleration failed message to the CDN parts, the failure cause that carries is: the high-grade application bandwidth accounting of network reaches A%; The bandwidth that takies such as high-grade application is lower than the A% of port total bandwidth, enters step S1112.

Step S1112, the bandwidth availability ratio of inquiring user place port reaches B% such as bandwidth availability ratio, the then network acceleration request of refusing user's, and return the network acceleration failed message to the CDN parts, the failure cause that carries is: the port bandwidth utilance reaches B%; Be lower than B% such as the port bandwidth utilance, then enter step S1114.

Step S1114, the downloading rate that the inquiring user current network connects, as reach C bit/s, then refuse this user's network acceleration request, and returning the network acceleration failed message to the CDN parts, the failure cause that carries is: the current downloading rate of user reaches C bit/s; Network downloading rate such as the user is lower than C bit/s, then enters step S1116.

Step S1116, the flow operating position that the inquiring user current network connects has reached D GB such as the flow that uses, and then refuses this user's network acceleration request, and returning the network acceleration failed message to the CDN parts, the failure cause that carries is: customer flow has reached D GB; Flow use such as the user is lower than D GB, then checks and passes through, and enters the request flow process of user network acceleration strategy, carries out this user's network acceleration strategy application.

Step S1118 feeds back the execution result of user network acceleration request to the CDN parts.

In a preferred implementation of the embodiment of the invention, above speed index is the statistical value in certain interval, but not instantaneous value, avoids frequent application and repeatedly.

By adopting the method, can based on network high-grade application bandwidth accounting situation, the bandwidth usage of user place port, the downloading rate that user's current network connects, the flow operating positions that user's current network connects etc. are carried out the admittance control of user network acceleration strategy.And in the inner realization of fusion device, based on the state of equipment self, finish by internal interface, realize simple.

Figure 12 is the flow chart according to the method for adjustment of the user content acceleration strategy of the embodiment of the invention three, and as shown in figure 12, the method comprising the steps of S1202 is to step S1210.

Step S1202, main control unit issues corresponding strategy to network components.

Main control unit issues content to network components and accelerates to adjust strategy; Specific strategy can customize as required.

For example, user place port bandwidth utilance reaches A% (supposing A%=90%), then triggers the content of the user under the corresponding port and accelerates to adjust strategy, and request content slows down, and it is congested to avoid port occurring; The downloading rate that the user uses when preacceleration has reached B bit/s(hypothesis B=50M), then trigger the content deceleration request for this user, avoid sole user's downloading rate too high; User's the downloading rate of using when preacceleration is lower than C bit/s(hypothesis C=5M), the content acceleration effect that then shows this user is not obvious, by network components to the content acceleration request of CDN parts application for this user, request content accelerates again, so that the CDN parts improve the content accelerated speed to this user's content acceleration guarantee.

Step S1204, after policy distribution and the deployment, network components sends content to main control unit and accelerates to adjust the strategy execution feedback information.

Network components can according to the corresponding state of tactful Real-Time Monitoring, be adjusted and control user's content acceleration after receiving that content accelerate to be adjusted strategy and successfully disposed.

Step S1206, the adjustment of bandwidth availability ratio Network Based.

The bandwidth availability ratio of network components Real-Time Monitoring user port reaches A% such as port utilization ratio, then needs the user content acceleration strategy under this port is adjusted, to reduce the bandwidth availability ratio of this port; Can carry out sort method based on downloading rate by network components to the current user who implements application acceleration, take off and carry a speed Top N(hypothesis N=100) reporting of user CDN parts, request content slows down.

The CDN parts are received the content deceleration request, carry out in the CDN components interior user's content is slowed down, and execution result is fed back to network components.

Step S1208 carries out the content deceleration based on the downloading rate that the user accelerates to use.

The downloading rate that network components Real-Time Monitoring user uses when preacceleration has reached B bit/s as downloading speed, then triggers the content deceleration request; Send content deceleration request for this user by network components to the CDN parts;

After the CDN parts are received content deceleration request for this user, carry out in the CDN components interior this user's content is slowed down; And execution result fed back to network components;

Step S1210 carries out the content acceleration based on the downloading rate that the user accelerates to use.

The downloading rate that network components Real-Time Monitoring user uses when preacceleration is lower than C bit/s as downloading speed, then triggers the content acceleration request; Send content acceleration request for this user by network components to the CDN parts;

After the CDN parts are received content acceleration request for this user, carry out in the CDN components interior this user's content is accelerated; And execution result fed back to network components;

By adopting said method, downloading rate and the bandwidth occupancy of adjusting the user are to send the user content deceleration request by network components to the CDN parts, thereby by the network downloading rate of CDN parts to user's content deceleration reduction user, reduce the port bandwidth utilance; Rather than adopt mode at the network components limiting bandwidth, and can avoid in network, causing congested and packet loss, thereby avoid the impact on equipment performance, also avoided owing to packet loss and the out of order impact that causes quality of service.

As can be seen from the above description, the present invention has realized following technique effect: according to the network state of equipment, user network connection status etc. is controlled user's network acceleration; According to the network state of equipment, user's content acceleration mode carries out suitable adjustment to user's content acceleration strategy.The better utilization of Optimizing Network Resources, the stability of raising network avoids the user to accelerate too much, the too high impact that causes network., avoided causing the congested and packet loss at network side because the user accelerates too highly to CDN parts feedback content deceleration request by network components, can reduce the impact on the network processes performance, avoided packet loss and the out of order impact that customer service is caused.
