信息中心网络（Information-centric networking， ICN）是一种新兴的范例，它将内容与主机分离，从而在未来的Internet中实现快速和经济高效的通信和内容分发。ICN的一个关键特征是部署无处不在的网络缓存，以加快服务交付和提高网络资源利用率。ICN缓存在缓存策略和缓存性能方面得到了广泛的研究。然而，到目前为止，ICN的经济方面得到了很少的考虑，尽管在ICN在服务提供商网络中广泛部署之前了解其潜在的成本效率是至关重要的。为了解决这一问题，我们提出了一种成本感知的缓存方案来研究ICN的服务质量（QoS）和成本，并研究它们之间的内在联系。设计了两个新的模型来描述异构突发内容请求下任意拓扑ICN的成本和QoS。采用多目标进化算法寻找缓存资源的最优分配。数值结果表明，该方案在ICN高速缓存中实现了成本效率和QoS保证。
Information-centric networking (ICN) is an emerg- ing paradigm that decouples content from the host to achieve fast and cost-efficient communication and content distribution in the future Internet. A key feature of ICN is the deployment of ubiquitous in-network caching to speed up service delivery and improve network resource utilisation. ICN caching has been widely studied in terms of caching strategies and caching performance. However, the economic aspect of ICN has received marginal consideration so far, although it is vital to understand the potential cost- efficiency of ICN before its wide deployment in service provider network. To address this issue, we propose a cost- aware caching scheme to study the Quality-of-Service (QoS) and cost of ICN and investigate the inner association between them. Two new models are designed to characterise the cost and QoS of ICN with arbitrary topology under heterogeneous bursty content requests. A multi- objective evolution algorithm is adopted to find the optimal cache resource allocation. Numerical results show the effectiveness of the proposed scheme in achieving cost- efficiency and QoS guarantee in ICN caching.
