Per-packet billing for a packet data network, mobile or fixed, is provided b y retrieving and processing all packets transported at a physical layer of the network, where the data packets are communicated with a traffic function tha t operates independently of a billing function. Using a billing-function computing resource, which is separate and independent from a traffic-functio n computing resource that processes traffic related information, the billing data are filtered out, processed, stored and distributed, without competing with the traffic functions of the network. Two independent physical layer interfaces separately couple a comunication link of the physical layer to th e billing-function computing resource and traffic-function computing resource, respectively.
