Abstract

Since ITU started to study the NGI (Next Generation Internet) architecture, the need to develop new Internet interconnection and access schemes has been growing. This study first introduces imperatives of an effective NUC (Network Usage Charging) framework for NGI services like VoIP and IP-TV. We start with analyzing the value chain structure in the NGI services, where NPs (Network Providers) and SPs (Service Providers; for e.g., VoIP providers) are key players. Special emphasis is given to identifying key economic factors for establishing a viable and efficient alternative of NUC so that it can create a promising marketplace for the NGI services. In particular, we identify and focus on the following components: (1) EB (Equivalent Bandwidth or Effective Bandwidth) for accurate estimation of network resource consumption, (2) T̅, industry benchmark of service-specific traffic load as a proxy for standard operating costs of an NP, (3) δ, contribution factor for inducing cooperation between NPs and SPs for effective end-to-end QoS. With these components as building blocks, developed is a new framework of NUC in order to properly address the NUC issues for NGI services. Our novel approach will encompass the ideas from the cost-based models as well as the revenue sharing models. The former pertains to the components (1) and (2), and the latter to the component (3) However, the proposed framework is more than a simple mix of the relevant ideas, and adequately combines key components in a well-organized and integrated form. The overall outline of the proposed framework is built upon the basis of a benefit sharing model, where the concept of the benefits is also closely connected with service-specific operating costs by means of WTP (Willingness-To-Pay) and EB. Specifically, we propose a simple equation as a novel NUC rule for NGI services. In the future research, we will analyze the potential impacts of the suggested NUC scheme on the social efficiency.
用于管理聚合服务的基于市场的框架
自从国际电联开始研究下一代互联网(NGI)架构以来,开发新的互联网互连和接入方案的需求不断增长。本研究首先介绍了NGI服务(如VoIP和IP-TV)的有效NUC(网络使用收费)框架的必要性。我们首先分析NGI服务的价值链结构,其中NPs(网络提供商)和sp(服务提供商);(例如,VoIP提供商)是关键的参与者。特别强调确定建立可行和有效的NUC替代方案的关键经济因素,以便为NGI服务创造一个有前途的市场。特别是,我们确定并关注以下组成部分:(1)EB(等效带宽或有效带宽),用于准确估计网络资源消耗;(2)T′s,特定服务流量负载的行业基准,作为NP标准运营成本的代理;(3)δ,用于诱导NP和sp之间合作以实现有效的端到端QoS的贡献因子。以这些组件为构建块,开发了一个新的NUC框架,以便正确地解决NGI服务的NUC问题。我们的新方法将包括基于成本的模型和收入共享模型的想法。前者与组件(1)和(2)有关,后者与组件(3)有关。然而,所提出的框架不仅仅是相关思想的简单混合,而且以良好组织和集成的形式充分结合了关键组件。建议架构的整体大纲是建立在利益分享模式的基础上,其中利益的概念也通过WTP(支付意愿)和EB与特定服务的运营成本密切相关。具体来说,我们提出了一个简单的方程作为NGI服务的新的NUC规则。在未来的研究中,我们将分析建议的NUC方案对社会效率的潜在影响。
