Pricing and charging are the most important management functionalities future commercial networks need to offer. Since the Internet is on the move to provide differentiated services, for the backbone based on the Differentiated Services Architecture (DiffServ), suitable and scalable management mechanisms are required. Based on a new view of pricing, considered as important management information, on one hand, the Cumulus Pricing Scheme (CPS) proposed targets particularly at DiffServ technology and it is the only approach known so far defining a clear relation between different time-scales of accounting periods, measurement periods, and charging periods. Prices in this scheme are based on flat fees and hence predictable and transparent. On the other hand the scheme is flexible enough to allow network management
