Bandwidth scheduling method and apparatus

A bandwidth scheduling method, comprising:

• receiving, by a message conversion apparatus, a second bandwidth request message sent by a user-side device, wherein the second bandwidth request message comprises a first bandwidth requirement, and the first bandwidth requirement is a bandwidth used for completing transmission of a first service;
• obtaining, by the message conversion apparatus, a first bandwidth request message according to the second bandwidth request message, wherein the first bandwidth request message comprises the first bandwidth requirement;
• sending, by the message conversion apparatus, the first bandwidth request message to a bandwidth allocation apparatus;
• receiving, by the message conversion apparatus, a first bandwidth response message sent by the bandwidth allocation apparatus, wherein the first bandwidth response message comprises first bandwidth grant information, and wherein the first bandwidth grant information is information about a bandwidth that is allocated to the user-side device and that corresponds to the first service;
• obtaining, by the message conversion apparatus, a second bandwidth response message according to the first bandwidth response message, wherein the second bandwidth response message comprises the first bandwidth grant information;
• and
• sending, by the message conversion apparatus, the second bandwidth response message to the user-side device.

A bandwidth allocation apparatus, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the processor, the programming instructions instructing the processor to:
• receive a bandwidth request message sent by a message conversion apparatus, wherein the bandwidth request message comprises a bandwidth requirement, and wherein the bandwidth requirement is a bandwidth used for completing transmission of a service;
• calculate first bandwidth grant information and second bandwidth grant information according to the bandwidth requirement, wherein the first bandwidth grant information is information about a bandwidth that is allocated to a user-side device and that corresponds to the service, and wherein the second bandwidth grant information is information about a bandwidth that is allocated to a second access device and that corresponds to the service;
• and
• send a first bandwidth response message to the message conversion apparatus, and send a second bandwidth response message to a first access device, wherein the first bandwidth response message comprises the first bandwidth grant information, and wherein the second bandwidth response message comprises the second bandwidth grant information.
