This enables bandwidth throttling and QoS guarantees for different users and different services. 2 is a schematic flowchart of another bandwidth adjustment method according to an embodiment of the present invention. As shown in FIG. 2, the method includes:

201. Acquire a message carrying a bandwidth parameter of the current user.

As an optional implementation manner, step 201 may include:

Obtain an access response message sent by the server that carries the bandwidth parameter of the current user.

Optionally, the server may be an AAA server, and the foregoing message may be an access response message (for example, an Access-Response message) in a Radius (a protocol name in the communication field, no specific Chinese meaning) protocol, that is, in the The access response message extends the bandwidth parameters of the current user.

As an optional implementation manner, the bandwidth parameter may include:

Maximum Bit Rate For Uplink (MBR-UL), Maximum Bit Rate For Downlink (MBR-DL), and Guaranteed Bit Rate For Uplink (GBR-UL) Guaranteed Bit Rate For Downlink (GBR-DL);

The bandwidth indicated by the bandwidth parameter may include:

When the network resource status does not reach the preset threshold, the uplink bandwidth indicated by the MBR-UL, and the downlink bandwidth indicated by the MBR-DL; or The uplink bandwidth indicated by the GBR-UL and the downlink bandwidth indicated by the GBR-DL when the network resource state reaches a preset threshold.

When the network resource status is greater than 80%, the bandwidth indicated by the bandwidth parameter may include: an uplink bandwidth indicated by the GBR-UL, and a downlink bandwidth indicated by the GBR-DL.

Optionally, the foregoing bandwidth parameter may be defined by using a Radius protocol in the form of a type, a length, and a value (for example, a type of character, a length of 8, and a value of abcdefgh). Four bytes are defined, where 1 byte is a type value, the other 1 byte is a length value, and the other 2 bytes are bandwidth values.

202. Configure, according to the obtaining the bandwidth parameter, a bandwidth indicated by the bandwidth parameter for the current user.

It should be noted that, in the present invention, the bandwidth configured for the user includes: the bandwidth configured by the access node (eg, AP or AC) for the user and the bandwidth configured by the gateway device for the user. Of course these two bandwidths can be the same. That is, when the user and the access node perform service transmission, the bandwidth configured by the access node for the user is used, and when the user transmits the service with the gateway device, the bandwidth configured by the gateway device for the user is used.

The service type identifier and the network status information may be carried by the IP packet header, and the service type identifier and the network status information may also be represented by the same field of the IP packet header. For example: the DSCP field and the Traffic Class field indicate that the DSCP field and the Traffic Class field are both composed of 8 bytes, so that the DSCP field and the Traffic Class field can be used to represent the service type identifier. The other 2 bytes represent the current network status information.

Optionally, when the foregoing information carries the current network status information, when the bandwidth currently used by the current service is subsequently adjusted, the current service type and the current network status may be used to adjust the current bandwidth used by the current service.

When the service type information of the current service is obtained, the bandwidth currently used by the current service may be adjusted according to the service type information to ensure the QoS of the current service. For example, if the service type of the current service is service type 1, step 205 can adjust the current bandwidth used by the current service to 1M. Of course, in the present invention, when the corresponding relationship information is not obtained in advance, the step 205 is also implemented.
