Abstract

Embodiments of the present invention provide a method and apparatus for adjusting physical resource, where the method includes: collecting load information of a control plane CP and a user plane UP, and calculating, according to the corresponding load information, to obtain a load of the CP and a load of the UP; calculating a quantity of to-be-adjusted physical resources in the case that the load of the CP and the load of the UP meet a preset balancing adjustment condition; and adjusting physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources. By means of the present invention, a physical resource can be adjusted and allocated automatically according to load statuses of a CP and a UP, so that balancing a load of a device, promoting usage of the device, and reducing a possibility that the CP and the UP are overloaded.

First claim

What is claimed is:

1 . A method for adjusting a physical resource, comprising:

2 . The method according to claim 1 , wherein the adjusting physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources comprises:
automatically adjusting the physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources; or sending adjustment instruction information according to the quantity of to-be-adjusted physical resources, to instruct a user to adjust the physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources.

3 . The method according to claim 1 , wherein the collecting load information of a CP from a CP board, collecting load information of a UP from a UP board, and obtaining, a CP workload according to the load information of the CP, and a UP workload according to the load information of the UP comprises:
collecting the load information of the CP in a preset time cycle from the CP board, collecting the load information of the UP in the preset time cycle from the UP board, and obtaining at least one CP load capacity according to the load information of the CP in the preset time cycle, and at least one UP load capacity according to the load information of the UP in the preset time cycle, wherein the load information comprises any one or more of the following: CPU usage, a quantity of users, and throughput; and determining a maximum value in the at least one CP load capacity or an average value of the at least one CP load capacity as the CP workload, and determining a maximum value in the at least one UP load capacity or an average value of the at least one UP load capacity as the UP workload.

4 . The method according to claim 1 , wherein the calculating a quantity of to-be-adjusted physical resources in the case that the CP workload and the UP workload meet a preset balancing adjustment condition comprises:
determining, in the case that the CP workload and the UP workload meet the preset balancing adjustment condition, a quantity of CP physical resources currently allocated to the CP and a quantity of UP physical resources currently allocated to the UP; and calculating the quantity of to-be-adjusted physical resources according to the quantity of CP physical resources currently allocated to the CP, the CP workload, the quantity of UP physical resources currently allocated to the UP, and the UP workload.

5 . The method according to claim 4 , wherein the calculating a quantity of to-be-adjusted physical resources comprises:
calculating the quantity of to-be-adjusted physical resources, so that an absolute value of a difference between a first load value and a second load value is within a preset range threshold; or calculating the quantity of to-be-adjusted physical resources, so that a ratio of a first load value and a second load value is within a preset range threshold; wherein the first load value is obtained by sharing a current total workload of the CP on each CP physical resource that is obtained after the adjusting is performed according to the quantity of to-be-adjusted physical resources, the second load value is obtained by sharing a current total workload of the UP on each UP physical resource that is obtained after the adjusting is performed according to the quantity of to-be-adjusted physical resources.

6 . The method according to claim 1 , wherein that the CP workload and the UP workload meet the preset balancing adjustment condition comprises:
an absolute value of a difference between the CP workload and the UP workload is beyond a preset range threshold; or a ratio of the CP workload and the UP workload is beyond a preset range threshold.

7 . The method according to claim 1 , wherein the adjusting physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources comprises:
in the case that the CP workload is smaller than the UP workload, changing a logic type of boards, which are in boards of the CP and whose quantity is indicated by the quantity of to-be-adjusted physical resources, into a UP logic type to implement a UP function; or in the case that the UP workload is smaller than the CP workload, changing a logic type of boards, which are in boards of the UP and whose quantity is indicated by the quantity of to-be-adjusted physical resources, into a CP logic type to implement a CP function.

8 . The method according to claim 1 , wherein the adjusting physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources comprises:
in the case that the CP workload is smaller than the UP workload, modifying a software configuration, deleting, according to the modified software configuration, CP software instances whose quantity corresponds to the quantity of to-be-adjusted physical resources, and creating, on physical resources that become idle, UP software instances whose quantity corresponds to the quantity of to-be-adjusted physical resources; or in the case that the UP workload is smaller than the CP workload, modifying a software configuration, deleting, according to the modified software configuration, UP software instances whose quantity corresponds to the quantity of to-be-adjusted physical resources, and creating, on physical resources that become idle, CP software instances whose quantity corresponds to the quantity of to-be-adjusted physical resources.

9 . The method according to claim 1 , wherein the adjusting physical resources of the CP and the UP according to the quantity of to-be-adjusted physical resources comprises:
in the case that the CP workload is smaller than the UP workload, reducing, according to the quantity of to-be-adjusted physical resources, a quantity of physical resources used by CP software instances, and allocating, to UP software instances for use, physical resources whose quantity corresponds to the quantity of to-be-adjusted physical resources that become idle; or in the case that the UP workload is smaller than the CP workload, reducing, according to the quantity of to-be-adjusted physical resources, a quantity of physical resources used by UP software instances, and allocating, to CP software instances for use, physical resources whose quantity corresponds to the quantity of to-be-adjusted physical resources that become idle.
