Abstract

A method of enabling traffic flow classification on a node, which may be used for controlling the traffic flows on the same node or on another node of a communication network. A first mapping process is configured to manage an operation for linking an application process to a class, and a second mapping process is configured to manage an operation for linking an application process to a unique signature. A third mapping process is configured to manage a record of accumulated linking information, such that a traffic flows associated with an application process may be identified and such that a classification of the respective traffic flow can be recognised. The accumulated classification information may then be used for controlling purposes.

Claims

1. A method of classifying traffic flows in a traffic generating node, each traffic flow being associated with an application process running on said traffic generating node, the method comprising:

performing a first mapping operation, such that an application process is linked to a class in response to having registered a selection or change of class for said application process,

performing a second mapping operation, such that an application process is linked to a signature that uniquely identifies a traffic flow and an associated socket in response to having registered an activity for said socket, and

activating a third mapping operation, such that a respective signature is linked to the respective class in response to having registered an activity associated with said first or second mapping operation that involves an active or closing application process,

thereby enabling accumulation of information on said linking of signature to class, which can be used for controlling said traffic flows.

2. The method according to claim 1, wherein said first mapping operation comprises a step of maintaining said mapping in a first list, and said second mapping operation comprises a step of maintaining said mapping in a second list.

3. The method according to claim 1, wherein said first mapping operation is executed according to a default classification.

4. The method according to claim 1, wherein said first mapping operation is executed in response to a user interaction.

5. The method according to claim 4, wherein said user interaction comprises the steps of:

dragging an icon that corresponds to an application to a class related symbol or between two different class related symbols on a user interface, and

dropping said icon on a class related symbol that represents a required class.

6. The method according to claim 1, wherein said class is associated with at least one rule, specifying at least one condition associated with a traffic flow that is linked to said class.

7. The method according to claim 1, wherein said class is associated with a priority, specifying how a traffic flow that is linked to said class is to be prioritized.

8. The method according to claim 1, wherein said second mapping operation comprises the steps of:

collecting information associated with said activated socket,

generating a signature associated with said application process on the basis of said collected information, and storing said signature in the second list together with an identifier identifying said application process, in response to having recognised a created socket, or

removing an entry from said second list, in response to having recognised that a socket associated with an application process has been removed.

9. The method according to claim 1, wherein said signature comprises:

protocol, the source IP address, the source port, the destination IP address and the destination port, associated with said socket.

10. The method according to claim 1, wherein a socket activity is registered by monitoring the associated application process.

11. The method according to claim 1, wherein a socket activity is registered in response to receiving a notification of such an activity from the associated application process.

12. The method according to claim 1, wherein said third mapping operation comprises the step of:

storing a mapping in a third list, in case a new mapping has been executed or a present mapping has been updated, or

removing an entry from said third list, in case a socket has been closed, or a class has been cancelled for an application process,

thereby enabling accumulation of information on said linking of signature to class, which can be used for classifying said traffic flows.

13. The method according to claim 12, further comprising the step of:

controlling at least one traffic flow on the basis of accumulated information stored in said third list.

14. The method according to claim 1, wherein said third mapping operation comprises the further steps of:

generating a notification comprising the signature to class linking or an indication that a linking has been removed from said first and second list,

transmitting said notification to at least one server, thereby enabling accumulation of information on said linking of signature to class at said server

15. A method at a server comprising at least one processing element for controlling at least one traffic flow on the basis of linked signature to class information accumulated, according to claim 14.

16. A traffic generating node for classifying traffic flows, each traffic flow being associated with an application process running on said traffic generating node, comprising:

a mapping manager adapted to perform a first mapping operation, such that an application process is linked to a class in response to the mapping manager having registered a selection or change of class for said application process,

a signature engine adapted to perform a second mapping operation, such that an application process is linked to a signature that uniquely identifies a traffic flow and an associated socket in response to the signature engine having registered an activity for said socket, and

an updating unit adapted to activate a third mapping operation, such that a respective signature is linked to the respective class in response to the updating unit having registered an activity associated with said first or second mapping operation that involves an active or closing application process.

17. The traffic generating node according to claim 16, wherein said mapping manager is adapted to maintain mappings in a first list, and said signature engine is adapted to maintain mappings in a second list.

18. The traffic generating node according to claim 16, wherein said mapping manager is adapted to execute a mapping according to a default classification.

19. The traffic generating node according to claim 16, wherein said mapping manager is adapted to execute a mapping in response to a user interaction.

20. The traffic generating node according to claim 19, wherein said node further comprises a graphical user interface adapted to register a requested classification of an application process by registering that an icon that corresponds to an application to a class related symbol has been dragged to or between two different class related symbols on a user interface, and that said icon has been dropped on a class related symbol that represents a required class.

21. The traffic generating node according to claim 16, wherein said signature engine comprises:

a recognising unit adapted to collect information associated with said activated socket,

a signature mapping unit adapted to generate a signature associated with said application process on the basis of said collected information, and to store said signature in the second list together with an identifier identifying said application process, in response to the signature mapping unit having recognised a created socket, or

to remove an entry from said second list, in response to the signature mapping unit having recognised that a socket associated with an application process has been removed.

22. The traffic generating node according to claim 16, wherein said node is adapted to register a socket activity by monitoring the associated application process.

23. The traffic generating node according to claim 16, wherein said node is adapted to register a socket activity in response to having received a notification of such an activity from an associated application process.

24. The traffic generating node according to claim 16, wherein said updating unit is adapted to:

store a mapping in a third list, in response to having recognised that a new mapping has been executed or that a present mapping has been updated, or

to remove an entry from said third list, in response to having recognised that a socket has been closed, or that a class has been cancelled for an application process.

25. The traffic generating node according to claim 24, comprising at least one processing element, said processing element being adapted to control at least one traffic flow on the basis of accumulated information stored in said third list.

26. The traffic generating node according to claim 16, wherein said updating unit is adapted to

generate a notification comprising the signature to class linking or an indication that a linking has been removed from said first and second list, and to

transmit said notification to at least one server, thereby enabling accumulation of information on said linking of signature to class at said server.

27. A server comprising at least one processing element, said processing element being adapted to control at least one traffic flow on the basis of linked signature to class information accumulated, according to claim 26.
