Abstract

Distributed Service Layer Transactions (DSLTs) may be supported by a DSLT service at a service layer of a communications network to offload applications from the burden of managing the processing of DSLTs.

Claims (32)

1. An apparatus comprising a processor, a memory, and an application executing on the apparatus configured to:

transmit, to a first service layer entity of the communications network, a request for a distributed service layer transaction, the request specifying a command to be atomically executed on a set of targeted resources, wherein the targeted resources are hosted by multiple other service layer entities of the communications network;

receive, from the first service layer entity of the communications network, a first status indicating that the targeted resources hosted by the multiple other service layer entities of the communications network have been locked;

transmit, to the first service layer entity of the communications network, a second request to execute the distributed service layer transaction on the set of locked targeted resources;

receive, from the first service layer entity of the communications network, a second status indicating that the distributed service layer transaction has been executed on the targeted resources hosted by the multiple other service layer entities of the communications network;

transmit, to the first service layer entity of the communications network, a third request to commit the results of the distributed service layer transaction on the set of locked targeted resources; and

receive, from the first service layer entity of the communications network, a third status indicating that the results of the distributed service layer transaction have been committed on the targeted resources hosted by the multiple other service layer entities of the communications network.

2. The apparatus of claim 1 , wherein the first service layer entity is configured to create, upon receipt of the second request, a resource representing the distributed transaction and comprising information concerning a state of the distributed transaction, wherein the resource is made accessible to the application via the communications network.

3. The apparatus of claim 2 , wherein the resource comprises a transaction identifier attribute that uniquely identifies the transaction and a transaction state attribute in which the information concerning the state of the distributed transaction is stored.

4. The apparatus of claim 2 , wherein the resource comprises an execution time attribute that controls when the first service layer entity initiates processing of the request for the distributed transaction.

5. The apparatus of claim 1 , wherein the apparatus comprises one of a device, a server or a gateway of the communications network.

6. The apparatus of claim 1 , wherein the first service layer entity is configured to process the request for the distributed transaction in accordance with a policy defining rules for processing the request.

7. The apparatus of claim 1 , wherein the first service layer entity is configured to schedule the processing of the request for the distributed transaction.

8. The apparatus of claim 1 , wherein the second request is for part of a sequence of requests.

9. The apparatus of claim 1 , wherein the first service layer entity is configured to send, to the multiple other service layer entities, criteria indicating restrictions on the execution of the command.

10. The apparatus of claim 1 , wherein the first service layer entity is configured to assign a priority to the requested distributed transaction.

11. A method performed by an application, comprising:

transmitting, to a first service layer entity of a communications network, a request for a distributed service layer transaction, the request specifying a command to be atomically executed on a set of targeted resources, wherein the targeted resources are hosted by multiple other service layer entities of the communications network;

receiving, from the first service layer entity of the communications network, a first status indicating that the targeted resources hosted by multiple other service layer entities of the communications network have been locked;

transmitting, to the first service layer entity of the communications network, a second request to execute the distributed service layer transaction on the set of locked targeted resources;

receiving, from the first service layer entity of the communications network, a second status indicating that the distributed service layer transaction has been executed on the targeted resources hosted by the multiple other service layer entities of the communications network;

transmitting, to the first service layer entity of the communications network, a third request to commit the results of the distributed service layer transaction on the set of locked targeted resources; and

receiving, from the first service layer entity of the communications network, a third status indicating that the results of the distributed service layer transaction have been committed on the targeted resources hosted by the multiple other service layer entities of the communications network.

12. The method of claim 11 , wherein the first service layer entity is configured to create, upon receipt of the second request, a resource representing the distributed transaction and comprising information concerning a state of the distributed transaction, wherein the resource is made accessible to the application via the communications network.

13. The method of claim 12 , wherein the resource comprises a transaction identifier attribute that uniquely identifies the transaction and a transaction state attribute in which the information concerning the state of the distributed transaction is stored.

14. The method of claim 12 , wherein the resource comprises an execution time attribute that controls when the first service layer entity initiates processing of the request for the distributed transaction.

15. The method of claim 11 , wherein the application is hosted on one of a device, a server or a gateway of the communications network.

16. The method of claim 11 , wherein the first service layer entity is configured to process the request for the distributed transaction in accordance with a policy defining rules for processing the request.

17. The method of claim 11 , wherein the first service layer entity is configured to schedule the processing of the request for the distributed transaction.

18. The method of claim 11 , wherein the second request is for part of a sequence of requests.

19. The method of claim 11 , wherein the first service layer entity is configured to send, to the multiple other service layer entities, criteria indicating restrictions on the execution of the command.

20. The method of claim 11 , wherein the first service layer entity is configured to assign a priority to the requested distributed transaction.
