基于使用情况的收费方案旨在确保连接费用能恰当反映网络所承受的负载。在多业务网络中，不同连接对带宽和服务质量的要求会给网络带来差异很大的负载。采用基于使用情况的收费方式，用户会有动力对其流量进行合理的优先级排序，而网络运营商的收入应与提供承载流量所需容量的投资相匹配。针对互联网和异步传输模式（ATM）网络，已经提出了几种收费方案。欧洲先进通信技术与服务（ACTS）项目“现金人”（多业务ATM网络中的收费与计费方案）正在研究这些问题。“现金人”项目旨在确定适合ATM收费方案的良好候选方案，开发必要的硬件和软件设施以便在用户试验中实施这些方案，并利用这些试验获取实施问题的经验以及用户反馈。在本文中，我们讨论了与基于使用情况的收费相关的重要问题，总结了这方面的研究，回顾了有效带宽，并提出了一种适用于对延迟敏感的连接、可容忍延迟的流量的收费方案、一个统一的定价模型以及它在“现金人”项目中是如何实施和试验的。
Usage-sensitive charging schemes aim to ensure that connection charges properly reflect the load imposed on the network. In multiservice networks the bandwidth and quality of service requirements of different connections can impose greatly differing loads. With usage-sensitive charging customers have an incentive to prioritise their traffic appropriately, and the network operator's revenue should match the investment required to provide capacity to carry the traffic. Several charging schemes have been proposed for the Internet and for ATM networks. The European ACTS project CA$hMAN (Charging and Accounting Schemes in Multiservice ATM Networks) is studying these issues. CA$hMAN aims to identify good candidates for ATM charging schemes, develop the necessary hardware and software facilities to implement them in user trials, and to use these trials to gain experience of implementation issues and to acquire user feedback. In this paper we discuss the important issues attached to usage-sensitive charging and summarise the research on this subject, review the effective bandwidth and present a charging scheme suitable for delay-sensitive connections, delay-tolerant traffic, a unified pricing model and how it is being implemented and trialled in project CA$hMAN.
