Bandwidth adjustment method and related device

A controller, comprising:

• a processor;
• and
• a non-transitory computer readable medium which contains computer-executable instructions;
• the processor is configured to execute the computer-executable instructions to perform operations comprising:
• obtaining behavior characteristic statistics sent by an end cloud node device, and obtaining bandwidth resources remaining on a system, wherein the behavior characteristic statistics are a statistical result indicating behavior characteristics of occupying network bandwidth resources by a user when accessing a service through the end cloud node device;
• determining, according to the behavior characteristic statistics and bandwidth resource remaining on the system, by the controller, a bandwidth adjustment amount allocated to the end cloud node device for service provisioning by the end cloud node device;
• and
• sending a bandwidth adjustment instruction to a first network device, wherein the bandwidth adjustment instruction is used to instruct the first network device to adjust, according to the bandwidth adjustment amount, a bandwidth allocated to the end cloud node device by a network device on a transmission link;
• wherein determining a bandwidth adjustment amount of the end cloud node device according to the behavior characteristic statistics and bandwidth resources remaining on the system comprises:
• determining a capability score according to the behavior characteristic statistics and a scoring parameter, wherein the capability score is used to reflect a service providing capability of the end cloud node device for the service provisioning;
• and
• determining the bandwidth adjustment amount of the end cloud node device according to the capability score and bandwidth remaining on the system.

An end cloud node device, comprising:

• a processor;
• and
• a non-transitory computer readable medium which contains computer-executable instructions;
• the processor is configured to execute the computer-executable instructions to perform operations comprising:
• collecting statistics about behavior characteristics of occupying network bandwidth resources by a user when accessing a service through the end cloud node device, to obtain behavior characteristic statistics;
• and
• reporting the behavior characteristic statistics to a controller, so that the controller determines, according to the behavior characteristic statistics and bandwidth remaining on a system, a bandwidth adjustment amount allocated to the end cloud node device for service provisioning by the end cloud node device.
