A service function chain including service functions which process user plane packets is controlled by providing (S) a shared context comprising rules and policies for processing the user plane packets, the shared context being shared between the service functions of the service function chain, reading (S) the shared context, and adjusting (S) traffic flow across the service function chain based on the rules and policies associated with the read shared context.

Controlling service function chaining

The invention introduces a method to inform/configure a peer-to-peer application environment such that an application can find good alternatives for peer selection and data exchange taking the network configuration conditions including caching strategies and deployment into account. In use, a mobile operator stores a tracker file that is used to provide information of likely locations of a data file sought by an end user. The mobile operator provides instructions to a mobile communication device of the end user regarding the location of a tracker file that is available for use by said mobile communication device. In this way, the mobile operator controls the peer-to-peer environment available to the end user.
