Abstract In this paper, the principle of the network pricing strategy (Per-Packet Billing，PPB) which is based on per-packet is proposed, the concept model of PPB and the simple implementation scheme is also presented. Aimed at the three kinds of services — FTP, HTTP and VoIP, comparison between PPB and traditional pricing strategy has been accomplished by NS2 simulation. The results show that the performance of PPB is better than the traditional pricing strategy in congestion control, and the packet-loss-rate is lower. Although the end-to-end delay increased, the influence to each kind of services is very small. PPB is fairness to each kind of user, and ISPs can also use price lever to optimize the network traffic and configure network resources properly.
