论文摘要
内容输送网络（CDN）是动态且复杂的服务系统。它在Internet服务提供商（ISP）的网络基础架构上引起大量流量。通常，CDN提供商和ISP努力寻找一种有效且适当的方式来合作获得相互利益。这项挑战是推动最终用户服务质量（QoS）的关键。我们对CDN的行为进行建模，模拟和优化以提供合作解决方案并改善QoS的行为。因此，我们确定合理的服务器位置，平衡服务器的数量并改善对服务器的用户分配。这些方面会影响运行时间效应，例如在服务器处的缓存，响应时间和特定链接的网络加载。特别是，用户请求历史记录和配置文件可改善整体性能。由于我们考虑了多种目标，因此我们旨在使用基于仿真的优化提供一套多样的帕累托最佳解决方案。
A Content Delivery Network (CDN) is a dynamic and complex service system. It causes a huge amount of traffic on the network infrastructure of Internet Service Providers (ISPs). Oftentimes, CDN providers and ISPs struggle to find an efficient and appropriate way to cooperate for mutual benefits. This challenge is key to push the quality of service (QoS) for the end-user. We model, simulate, and optimize the behavior of a CDN to provide cooperative solutions and to improve the QoS. Therefor, we determine reasonable server locations, balance the amount of servers and improve the user assignments to the servers. These aspects influence run time effects like caching at the server, response time and network load at specific links. Especially, user request history and profiles are considered to improve the overall performance. Since we consider multiple objectives, we aim to provide a diverse set of pareto optimal solutions using simulation based optimization.
