Methods, systems and apparatus for billing network usage in a network are provided. Statistics of subscribers' network usage and subscriber information are transmitted from a plurality of First Hop Multicast Routers (FHMRs) to a Net Flow Collection Server (NFCS). The NFCS consolidates the statistics received and subscriber information into a report. Thereafter, a Billing Module (BM) prepares subscribers billing information based on the report and policies configured on the BM. Advantageously, subscribers are charged based on their individual network usage.
