Abstract

In an apparatus of a communication network first packets of a data flow in a first direction are acquired, each having a first service chain identifier identifying a first chain of services which have been applied to the first packets in the first direction of the data flow. The first service chain identifier represents a classification result of classification functions used for selecting the first chain of services. Based on the first service chain identifier, a packet filter is calculated, which is associated with a second chain of services to be applied to second packets of the data flow in a second direction of the data flow when the second packets enter the communication network in the second direction.
