Collecting per-packet billing data in a packet data service

Per-packet billing for a packet data network, mobile or fixed, is provided by retrieving and processing all packets transported at a physical layer of the network, where the data packets are communicated with a traffic function that operates independently of a billing function. Using a billing-function computing resource, which is separate and independent from a traffic-function 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 communication link of the physical layer to the billing-function computing resource and traffic-function computing resource, respectively.
