Abstract

Method for allowing distributed running of an application between a device and a server connected via a network. The method includes the following steps carried out by the device: obtaining a device profile including resource capacity characteristics of the device; obtaining an application profile including resource consumption characteristics of the application; obtaining device metrics relating to real-time resource usage with respect to the device; obtaining offload rules defining conditions under which an application is to be run at least in part on a server and/or on a device, the conditions involving device resource capacity, application resource consumption and device real-time resource usage; and making a decision by an inference engine to run the application at least in part on the server and/or on the device, by evaluating the offload rules applied to the device profile, application profile and device metrics.

Claims

1. A method for allowing distributed running of an application between a device and a server connected via a network, the method comprising the following steps carried out by the device:

obtaining, by said device, a device profile including resource capacity characteristics of said device;

obtaining, by said device, an application profile including resource consumption characteristics of said application before said application is run;

obtaining, by said device, device metrics relating to real-time resource usage with respect to said device;

obtaining, by said device, offload rules defining conditions under which said application is to be run at least in part on said server and/or on said device, the conditions involving device resource capacity, application resource consumption and device real-time resource usage;

making a decision, by an inference engine of said device, to run said application completely locally on said device, completely remotely on said server or partially on said device and partially on said server, by evaluating the offload rules applied to said device profile, application profile and device metrics; and

controlling distribution of the application running between the device and the server based on said decision.

2. The method as claimed in claim 1, wherein the application profile is obtained from a pre-processing unit arranged for performing analysis of a code of said application.

3. The method as claimed in claim 1, wherein the application profile is received responsive to the device requesting downloading of said application.

4. The method as in claim 1, wherein the device is provided with the offload rules by an operator of the network.

5. The method as claimed in claim 4, wherein the offload rules depend on a type of subscription a user of the device has with the network.

6. The method as claimed in claim 1, wherein the device is provided with the device profile by a manufacturer of the device.

7. The method as claimed in claim 1, wherein device resource capacity, application resource consumption and/or device real-time resource usage relate to at least one of the following resources:

processing resource, random access memory, storage memory, power or network bandwidth.

8. The method as claimed in claim 1, further comprising, when the decision made by the inference engine is to run the at least part of said application on the server, offloading said application part to the server.

9. The method as claimed in claim 8, further comprising a plurality of different forms of offloading, wherein each of the different forms of offloading corresponds to a different one of the conditions defined by the offload rules or corresponds to a different combination of multiple ones of the conditions defined by the offload rules, and wherein offloading the at least part of said application to the server is performed by one of the different forms of offloading that corresponds to one or more of the conditions, defined by the offload rules, that provoked the inference engine to make the decision to run the at least part of said application on the server.

10. The method as claimed in claim 1, wherein the resource consumption characteristics included in the application profile are generated at least in part by analyzing a source code language of said application.

11. The method as claimed in claim 10, wherein analyzing the source code language of said application comprises performing a semantic analysis of the source code language of said application.

12. The method as claimed in claim 1, wherein the application profile is built prior to execution of the application on at least one of the device or the server.

13. A device for allowing distributed running of an application between the device and a server connected via a network, the device comprising:

an inference engine configured to;

receive a device profile including resource capacity characteristics of said device;

receive an application profile including resource consumption characteristics of said application;

receive device metrics relating to real-time resource usage with respect to said device;

receive offload rules defining conditions under which said application is to be run at least in part on said server and/or on said device, the conditions involving device resource capacity, application resource consumption and device real-time resource usage, wherein the offload rules depend on a type of subscription a user of the device has with the network;

make a decision to run said application at least in part on said server and/or on said device, by evaluating the offload rules applied to said device profile, application profile and device metrics; and

control distribution of the application running between the device and the server based on said decision.

14. The device of claim 13, wherein the type of subscription that the user of the device has with the network comprises one of a plurality of subscription types, wherein each of the plurality of subscription types has a different remote running capacity for running said application.

15. A non-transitory computer-readable medium, storing instructions of an inference engine to implement a method for allowing distributed running of an application between a device and a server connected via a network, when the instructions are executed by a computer, wherein the method comprises:

obtaining a device profile including resource capacity characteristics of said device;

obtaining an application profile including resource consumption characteristics of said application before said application is run;

obtaining device metrics relating to real-time resource usage with respect to said device;

for obtaining offload rules defining conditions under which said application is to be run at least in part on said server and/or on said device, the conditions involving device resource capacity, application resource consumption and device real-time resource usage;

making a decision to run said application completely locally on said device, completely remotely on said server or partially on said device and partially on said server, by evaluating the offload rules applied to said device profile, application profile and device metrics; and

controlling distribution of the application running between the device and the server based on said decision.
