ITR: A Unified Experimental Testbed to Compare Bandwidth Contract Choices for Differentiated Service Networks

向具有不同使用概况的客户提供差异化网络服务的想法正在获得强有力的商业支持。 许多公司正在提供基于策略的管理解决方案，以实现所需的服务质量（QoS）。 这些基于网络的服务范围从应用级控制到带宽管理。 然而，决定或设计这些策略的责任在于网络管理员。 大多数解决方案提供商所采取的观点是一个静态的组织，在这个组织中，可以预先评估需求。 因此，在用户方面，过度提供服务已成为一种常态。该提案研究了商业环境中差异化网络服务安排的经济性，以及现实网络环境的设计和开发，以进行实验并评估各种定价方法的性能。 我们建议调查的方法，从纯粹的确定性保证的QoS，通过合同的实时定价，为消费者提供选择购买的QoS为每个应用程序在消费时的范围。为了测试各种定价方案，将使用令牌桶范例。它将模拟给定的价格/合同安排。该项目开发的经济实验框架将提供一个基准工具，用于评估不同合同安排下的网络效率。

The idea of providing differentiated network services to customers with different usage profiles is gaining strong commercial support. Many companies are providing solutions to policy-based management for desired Quality of Service (QoS). These network-based services range from application level control to bandwidth management. However, the onus of deciding or designing these policies rests on network managers. The view taken by most solution providers is that of a static organization where requirements can be assessed in advance. Consequently, at the user end overprovision of services has become a norm. This proposal investigates the economics of differentiated network service arrangements in business environments and the design and development of realistic network environments to conduct experiments and evaluate performance of a wide class of pricing approaches. The class of approaches we propose to investigate range from purely deterministically guaranteed QoS through contracts to real-time pricing that provides consumers with option to buy a QoS for each application at the time of consumption. To test the various pricing schemes, the token-bucket paradigm will be used. It will simulate a given price/contract arrangement. The framework for economic experiments developed by this project will provide a benchmark tool to assess network efficiency under different contractual arrangements.
