Abstract

The invention relates to connection management in a telecommunication network and particularly relates to a method ( 30 ) for managing telecommunication network connections, comprising a step of creating at least one list (L 1 , L 2 , . . . , L N , L N+1 ) of connections, said list being associated to a time interval (D L1 , D L2 , . . . , D LN , D LN+1 ) having a predetermined period and used to record at least one active connection (C 1 ), for example, for which a transfer of a packet has been detected, in the time interval associated to the considered list.

First claim

The invention claimed is:

1. A method for managing connections of a telecommunications network, comprising:
creating, using a processor of a node of the network, a plurality of distinct connection lists each associated with one of a plurality of time intervals of predetermined durations, respectively;
storing the plurality of connection lists in a memory that is accessible by the node;
detecting a packet transiting through the node in a first time interval, the packet belonging to a first connection; and
cataloguing said first connection to a first connection list that is associated with the first time interval in which said packet was detected.

2. The method as claimed in claim 1 , wherein said cataloguing further comprises:
creating the first connection list when an end of a time interval that is associated with one of the plurality of connection lists that was previously created is detected.

3. The method as claimed in claim 2 , further comprising:
deleting the first connection list.

4. The method as claimed in claim 3 , wherein the step of deleting and the step of creating performed simultaneously.

5. The method as claimed in claim 3 , wherein the first connection list was created prior to a predetermined number of lists.

6. The method as claimed in claim 1 , wherein said cataloguing further comprises:
adding the first connection as a current connection to the first connection list associated with the first time interval, the current connection including a date of detection of transition of the packet belonging to the current connection.

7. The method as claimed in claim 6 , further comprising:
deleting the current connection from a second connection list associated with a second time interval after the current connection is cataloged in a connection list that is different from the second connection list to which the current connection was added and is associated with a time interval different from the second time interval.

8. The method as claimed in claim 7 , further comprising:
recording a time associated with the current connection, the time corresponding to the time at which the transition of the packet belonging to the current connection has been detected.

9. The method as claimed in claim 6 , further comprising:
recording the time at which the transition of the packet belonging to the current connection has been detected.

10. The method as claimed in claim 9 , further comprising:
determining whether an elapsed duration between a time associated with the current connection and the time of detection of the packet belonging to the current connection is greater than a threshold value; and
deleting the current connection from the first connection list after said step of determining has determined that the time is above the threshold value.

11. The method as claimed in claim 1 , wherein said cataloguing further comprises:
detecting whether a time of transition of the packet is within one of the plurality of time intervals; and
creating the first connection list after said detecting confirms that the time of transition of the packet is not within the plurality of time intervals that are associated to the plurality of connection lists.

12. The method as claimed in claim 1 , further comprising:
deleting a connection of a connection list that was created prior to a predetermined number from the plurality of the connection lists, when the deleted connection is different from the connection for which the packet has been detected by said step of detecting.

13. A non-transitory data-storage medium including instructions that, when executed on a computer, cause the computer to perform a method of managing connections, the method comprising the steps of:
creating, using a processor of a node of a network, a plurality of distinct connection lists each associated with one of a respective plurality of time intervals of predetermined durations, respectively, each of the lists intended to catalog at least one connection for which at least one packet has been detected in the time interval associated with the list;
storing the plurality of connection lists in a memory that is accessible by the node;
detecting a packet transiting through the node in a first time interval, the packet belonging to a first connection; and
cataloguing said first connection to a first connection list that is associated with the first time interval in which said packet was detected.

14. The data-storage medium as claimed in claim 13 , said method further comprising:
creating the first connection list when an end of a time interval that is associated with one of the plurality of connection lists that was previously created is detected.

15. The data-storage medium as claimed in claim 13 , said method further comprising:
creating a first connection list when the transition of the packet of a connection at a time does not belong to any of the time intervals associated with the plurality of connection lists that were previously created is detected.

16. The data-storage medium as claimed in claim 13 , said method further comprising:
deleting a connection from a first connection list that was created prior to a predetermined number from the plurality of the connection lists, when the deleted connection is different from the connection for which the packet has been detected by said step of detecting.

17. A device for managing connections of a telecommunications network, comprising a hardware processor and a memory, the hardware processor configured to
create a plurality of distinct connection lists each associated with one of a plurality of time intervals of predetermined durations, respectively;
store the plurality of connection lists in the memory;
detect a packet transiting through the device in a first time interval, the packet belonging to a first connection; and
catalogue said first connection to a first connection list that is associated with the first time interval in which said packet was detected.

18. A method for managing connections of a telecommunications network, comprising:
creating, using a processor of a node of the network, a plurality of distinct connection lists each associated with one of a plurality of time intervals of predetermined durations, respectively;
storing the plurality of connection lists in a memory that is accessible by the node;
detecting a packet transiting through the node in a first time interval, the packet belonging to a first connection;
cataloguing said first connection to a first connection list that is associated with the first time interval in which said packet was detected, said cataloguing comprising:
detecting whether a time of transition of the packet is within one of the plurality of time intervals; and
creating the first connection list after said detecting confirms that the time of transition of the packet is not within the plurality of time intervals that are associated to the plurality of connection lists.

19. A device for managing connections of a telecommunications network, comprising a hardware processor and a memory, the hardware processor configured to
create a plurality of distinct connection lists each associated with one of a plurality of time intervals of predetermined durations, respectively;
store the plurality of connection lists in the memory;
detect a packet transiting through the device in a first time interval, the packet belonging to a first connection; and
catalogue said first connection to a first connection list that is associated with the first time i
