Method and monitoring component for network traffic monitoring
First Claim
1. A method for monitoring traffic in a network, the network comprising a first monitoring component, the method comprising:
- providing a first set of local identifiers selected from a larger second set of local identifiers locally used within a network node to identify a user terminal for monitoring traffic thereof and the first set of local identifiers and the second set of local identifiers provide unique identification of a network connection at the first monitoring component;
filtering incoming connection setup messages;
allocating a local identifier of the first set of local identifiers to the network connection if a filter condition applies during the filtering;
checking incoming data packets for associations with the first set of local identifiers; and
selectively monitoring network traffic associated with the local identifier of the first set of local identifiers.

Abstract
A technique for traffic monitoring in a network comprising monitoring components and a management center (MC) is described. A method implementation comprises the steps of selecting a first set of local identifiers from a larger second set of local identifiers, wherein the local identifiers are capable of providing a unique identification of a network connection at the first monitoring component, filtering network connections, allocating a local identifier of the first set of local identifiers to a network connection in case a filter condition applies during the filtering, checking associations of network traffic with local identifiers, and selectively monitoring network traffic associated with a local identifier from the first set of local identifiers.

13. A method for monitoring traffic in a network, the network comprising at least a first monitoring component, the method comprising:
-
forwarding filter conditions to the at least one monitoring component for filtering incoming connection setup messages; and receiving a first set of local identifiers from the at least one monitoring component, wherein the first set of local identifiers has been selected from a larger second set of local identifiers and is locally used within a network node to identify a user terminal for monitoring traffic thereof and provide unique identification of a particular network connection. - View Dependent Claims (14, 15, 16, 17)

18. A monitoring component for monitoring traffic in a network, the monitoring component comprising:
-
a processor; and a non-transitory computer-readable medium, coupled to the processor, the non-transitory computer-readable medium comprising computer-readable instructions, when executed by the processor, are configured to; provide a first set of local identifiers selected from a larger second set of local identifiers locally used within a network node to identify a user terminal for monitoring traffic thereof and provide a unique identification of a network connection at the monitoring component, filter incoming connection setup messages, allocate a local identifier of the first set of local identifiers to a network connection if a filter condition applies when filtering incoming connection setup messages, check incoming data packets for associations with the first set identifiers, and selectively monitor network traffic associated with the local identifier of the first set of local identifiers.

19. A management center for monitoring traffic in a network, the management center comprising:
-
a processor; a non-transitory computer-readable medium, coupled to the processor, the non-transitory computer-readable medium comprising computer-readable instructions, when executed by the processor, are configured to; forward filter conditions to at least one monitoring component for filtering incoming connection setup messages; and an interface adapted to receive a first set of local identifiers from the at least one monitoring component, wherein the first set of local identifiers has been selected from a larger second set of local identifiers and is locally used within a network node to identify a user terminal for monitoring traffic thereof and provide a unique identification of a particular network connection.
