Abstract

An arrangement and a method comprising maintaining knowledge of a number of current network connections that require performing a periodic network operation (204, 206, 208, 210), with one or more predetermined timing sequences, targeted to at least one remote entity for maintaining the connections, and adjusting the time of execution of at least two such network operations to regularly substantially coincide (212).

Claims

1. An electronic apparatus comprising

a transmitter for transmitting data to at least one remote entity over a communication network,

a receiver for receiving data from said at least one remote entity over said communication network, and

a scheduler entity configured to maintain knowledge of a number of current network connections that require performing a periodic network operation, with one or more predetermined timing sequences, targeted to said at least one remote entity for maintaining the connections, and to adjust the time of execution of at least two such network operations to regularly substantially coincide.

2. The apparatus of claim 1, arranged to receive at least part of said knowledge from said remote entity via said receiver.

3. The apparatus of claim 1, wherein said scheduler entity is configured to receive said knowledge from one or more client entities managing said number of network connections in the apparatus.

4. The apparatus of claim 1, wherein said scheduler entity is configured to obtain at least part of said knowledge by accessing a predetermined memory location in the apparatus associated with a client entity managing one or more of the network connections in the apparatus.

5. The apparatus of claim 1, wherein said scheduler entity is configured to trigger a number of client entities to perform the network operations according to the adjusted timing.

6. The apparatus of claim 1, wherein said scheduler entity is arranged to perform at least part of the network operations by said transmitter according to the adjusted timing.

7. The apparatus of claim 1, wherein said scheduler is arranged to provide instructions to a number of clients about proper timing of the network operations as adjusted.

8. The apparatus of claim 1, wherein a timing sequence defines a keep-alive time within which a periodic network operation shall be performed since the previous network operation for maintaining a network connection.

9. The apparatus of claim 1, wherein a timing sequence includes a set of rules defining the interrelations between sequential network operations for maintaining a network connection.

10. The apparatus of claim 1, wherein a timing sequence includes a mathematic formula defining the interrelations between sequential network operations for maintaining a network connection.

11. The apparatus of claim 1, wherein a periodic network operation includes sending a keep-alive message to said at least one remote entity.

12. The apparatus of claim 1, configured to instruct an external entity to time said periodic network operations.

13. An apparatus comprising

means for transmitting data to at least one remote entity over a communication network,

means for receiving data from said at least one remote entity over said communication network, and

means for maintaining knowledge of a number of current network connections that require performing a periodic network operation, with one or more predetermined timing sequences, targeted to said at least one remote entity for maintaining the connections, and for adjusting the time of execution of at least two such network operations to regularly substantially coincide.

14. A method for adjusting the time of execution of network operations comprising:

obtaining information about a number of network connections that require performing a periodic network operation, with one or more predetermined timing sequences, targeted to at least one remote entity for maintaining the connections,

storing said information,

adjusting the time of execution for at least two such network operations to regularly substantially coincide, and

performing said at least two network operations according to the adjusted timing.

15. The method of claim 14, wherein said obtaining includes receiving said knowledge from one or more client entities managing said number network connections in the apparatus.

16. The method of claim 14, wherein a timing sequence includes a keep-alive time within which a periodic network operation shall be performed since the previous network operation for maintaining a network connection.

17. The method of claim 14, comprising sending, according to the adjusted timing, a triggering command to a client entity for performing the network operation in order to maintain the associated connection.

18. An apparatus comprising:

a processor,

a memory including computer program code,

the memory and the computer program code configured to, with the processor, cause the apparatus at least to perform;

obtaining information about a number of network connections that require performing a periodic network operation, with one or more predetermined timing sequences, targeted to at least one remote entity for maintaining the connections,

storing said information, and

adjusting the time of execution for at least two such network operations to regularly substantially coincide.

19. The apparatus of claim 18, further configured to obtain said information in a message received from a local client entity or said at least one remote entity.

20. The apparatus of claim 18, further configured to trigger the execution of the number of network operations.

21. The apparatus of claim 18, further configured to adjust said time on the basis of a keep-alive time included in the obtained and stored information, said keep-alive time defining a time interval within which a periodic network operation shall be performed since the previous network operation for maintaining a certain network connection.
