Method and monitoring component for network traffic monitoring

摘要

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.

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.
