以信息为中心的网络（ICN）是未来互联网架构的一种新范式。它利用了目前互联网使用的趋势，主要涉及信息传播。基于发布/订阅模型的ICN架构使用名称作为信息，以便路由请求和数据，以及促进网络内缓存、任播和多播，以实现高效的内容交付。然而，在未来的互联网中，命名信息对象的数量预计将是巨大的，这引起了人们对国际竞争网络全球规模部署的严重关切。路由和转发将需要大量的状态，这将存储，维护和处理需求推向极限。在本文中，我们讨论了部署的数据导向网络架构（DONA），利用云计算设施的可行性。我们确定了确切的可扩展性问题DONA的基础上模拟在一个现实的模型，目前的互联网拓扑结构，并发现注册信息对象导致状态爆炸。出于这个原因，我们然后讨论云设施如何帮助DONA部署，重点是在云中部署DONA的各种选项及其对互联网不同区域的适用性。
Information-Centric Networking (ICN) is a novel paradigm for future Internet architectures. It exploits the current trend in Internet usage which mostly involves information dissemination. ICN architectures based on the publish/subscribe model use names for information in order to route requests and data, as well as to facilitate in-network caching, anycasting and multicasting for efficient content delivery. However, the number of named information objects is expected to be huge in the future Internet, raising serious concerns with respect to a global-scale deployment of ICN. Routing and forwarding will require vast amounts of state, which pushes storage, maintenance and processing demands to the limit. In this paper we discuss the feasibility of deploying the Data Oriented Networking Architecture (DONA) by leveraging cloud computing facilities. We identify the exact scalability concerns for DONA based on simulations over a realistic model of the current Internet topology and find that registrations for information objects lead to a state explosion. For this reason, we then discuss how cloud facilities can assist DONA deployment, focusing on various options for deploying DONA in the cloud and their suitability for different areas of the inter-network.
