Centralized acceleration abstraction layer for ran virtualization

2:

• The method according to claim 1, wherein the AAL broker interacts with the shared accelerating computing infrastructure as an individual vRAN node.

3:

• The method according to claim 1, wherein the operation request comprises information about the operation that shall be accelerated, the data to execute the operation, and settings to execute the operation.

4:

• The method according to claim 1, further comprising:
• performing, by the selected physical hardware accelerator, the operation in a FIFO manner considering the requests in the processing queue

6:

• The method according to claim 1, wherein the scheduling policy used by the AAL broker to select the physical hardware accelerator for accelerated execution of the operation is implemented with a machine learning;
• (ML) model minimizing a cost function that combines information about network throughput and energy consumption of the shared accelerating computing infrastructure.

7:

• The method according to claim 1, further comprising:
• using a resource controller to configure the AAL broker by deploying computing policies via an O3 interface.

8:

• The method according to claim 1, further comprising:
• using a resource controller to configure radio resource policies of vRAN nodes via an E2 interface, and/or to notify changes on radio resource policies configured on vRAN nodes to Near-RT RIC via another E2 interface.

10:

• The system according to claim 9, wherein the AAL broker is configured to interact with an underlying O-RAN AAL infrastructure.

12:

• The system according to claim 9, wherein the AAL broker is further configured to perform the selecting of the physical hardware accelerator for accelerated execution of the operation by means of a machine learning model minimizing a cost function that combines information about network throughput and energy consumption of the shared accelerating computing infrastructure.

13:

• The system according to claim 9, further comprising a resource controller configured to configure the AAL broker via an O3 interface.

14:

• The system according to claim 13, wherein the resource controller is further configured to configure radio resource policies of vRAN nodes via an E2 interface.

15:

• The system according to claim 13, wherein the resource controller is further configured to notify changes on radio resource policies configured on vRAN nodes to Near-RT RIC via an E2 interface.
