Abstract

A method of service balancing in an electronic communications system. The method comprises receiving (210) a service request for a service to be invoked in the data communication system; determining (220) a current services balance of the electronic communications system; based on the current services balance, determining (230) if and when the service is to be invoked; and invoking (240a) or rejecting (240c) the service.

Claims

1. A method of service balancing in an electronic communications system, the method comprising:

receiving a service request for a service to be invoked in the communication system;

determining a current services balance of the communications system, based on a comparison of a current performance of the communications system with a performance model;

based on the current services balance, determining whether the service is to be invoked; and

invoking or rejecting the service.

2. The method according to claim 1, wherein determining the current services balance comprises:

selecting and simulating the performance model associated with the service request;

based on a result of the simulating, generating estimates of Key performance Indexes; and

determining the current services balance based on the estimates of the Key performance Indexes.

3. The method according to claim 2, wherein determining that the service is to be invoked, comprises:

generating a decision based on the estimates of the Key performance Indexes whether the service request should continue, wait or be rejected.

4. The method according to claim 1, wherein determining a current services balance is based on the current performance of the communications system.

5. The method according to claim 4, further comprising:

for each service, collecting service execution related information, including a starting time stamp of invocation of the service, a resulting time stamp when the service is completed, and a service ID; and

calculating the current performance of the communication system based on the service execution related information.

6. The method according to claim 5, further comprising:

comparing the current performance with the performance model for determining the current services balance.

7. The method according to claim 6, further comprising:

analyzing a result of comparing the current performance with the performance model; and

updating the performance model based on the result of the analyzing.

8. The method according to claim 1, wherein the service is a chain of partial services.

9. A computer program comprising computer program instructions stored on a non-transitory computer readable medium, wherein the computer program is configured to cause a computer to perform the method of claim 1, when said program is run on a computer.

10. A computer program on a non-transitory carrier and comprising computer executable instructions for causing a computer to perform the method according to claim 3, when said program is run on a computer.

11. A computer program according to claim 10, wherein said non-transitory carrier is a recordable medium, computer memory, and/or read-only memory.

12. A computer program product comprising a non-transitory computer readable medium, having stored thereon:

computer program code, when said program code is loaded, to make a computer execute the method of claim 7.

17. The service balancing device according to claim 1, wherein the service is a chain of partial services.

20. The method according to claim 1, wherein determining the current services balance comprises:

selecting the performance model that is associated with the service request;

generating estimates of Key Performance Indexes based on the performance model; and

determining the current services balance based on the estimates of the Key Performance Indexes.

13. A service balancing device for performing service balancing in a data communications system, comprising:

a service controller configured to;

receive a service request;

request a determination of a current services balance;

receive a decision based on the current services balance, wherein the current services balance is based on a comparison of a current performance of the communications system with a performance model, about whether the service request should continue, wait or be rejected;

based on the decision, determine whether the service is to be invoked; and

invoke or reject the service.

14. A service balancing device according to claim 13, further comprising:

a service parser configured to;

receive the service request;

determine a type of the requested service to be executed by the data communications system; and

forward the service request to the service controller.

15. A service balancing device according to claim 13, further comprising:

an admission controller configured to;

receive a request for determination of the current services balance from the service controller;

select and simulate the performance model associated with the service request for generating estimates of Key performance Indexes; and

generate a decision for the service controller based on the estimates of the Key performance Indexes whether the service request should continue, wait or be rejected.

16. The service balancing device according to claim 15, wherein the admission controller is configured to:

receive service execution related information for each service executed by the data communication system, said service execution related information including a starting time stamp of invocation of the service, a resulting time stamp when the service is completed, and a service ID;

calculate the current performance of the communication system based on the service execution related information;

compare the current performance with the performance model for determining the current services balance;

analyze a result of comparing the current performance with the performance model; and

update the performance model based on the result of the analysis.

18. A method of service balancing in an electronic communications system, the method comprising:

determining a current services balance of the communications system from a comparison of a current performance of the communications system with a predetermined performance model; and

controlling an arrival rate of service requests into the communications system based on the current services balance of the communications system.

19. The method of claim 18, wherein controlling the arrival rate of the service requests comprises:

receiving a service request for a service to be invoked in the communication system;

determining that the service is to be invoked or is not to be invoked based on the current services balance;

invoking the service responsive to determining that the service is to be invoked; and

rejecting the service request responsive to determining that the service is not to be invoked.
