METHOD AND TRAFFIC PROCESSING UNIT FOR HANDLING TRAFFIC IN A COMMUNICATION NETWORK

Abstract:

A method and a traffic processing unit (200) for handling traffic in a communication network when the traffic is distributed across a set of traffic processing units. When receiving a packet of a traffic flow distributed to said traffic processing unit, the traffic processing unit (200) assigns a packet class to the received packet, which class can be active or inactive in the traffic processing unit. The traffic processing unit obtains state information of the assigned packet class. If the packet class is detected as active the state information is retrieved from a local storage (200C) in the traffic processing unit, and if the packet class is detected as inactive the state information is fetched from a central storage (204). The traffic processing unit then performs stateful packet processing of the received packet based on the obtained state information.
