在过去的十年里,互联网服务模式已经从资源共享转向内容分发。某些应用程序,如大型科学数据、cdn、VoIP和多媒体应用程序,在Internet上以时间限制的方式传输大量数据,这需要保证网络内资源。网络社区通常通过创建点对点保证带宽路径来实现这一点。然而,当前的资源预留解决方案是端到端的,并且通常由不了解底层网络条件的用户发起。因此,流经这些保留隧道的数据不能被重用,网络内的资源也不能得到最优的利用。相反,像NDN[16]这样的以信息为中心的网络架构有几个属性可以更智能地促进资源预留。在这项工作中,我们提出了ICN中的策略缓存和保留(SCARI),这是一种在ICN网络上保留资源的协议。与IP网络中的RSVP[17]类似,SCARI在实际数据传输之前充当信令机制。在这项工作中,我们明确地关注科学数据流,而不是其他类型的流量,如实时音频/视频。我们展示了SCARI通过聚合保留和战略性地缓存网络中的内容来减少网络资源消耗。
In the last decade, the Internet service model has shifted from sharing resources to distributing content. Certain applications such as large science data, CDNs, VoIP and multimedia applications transfer a significant amount of data over the Internet in a time-constrained manner that requires guaranteed in-network resources. The networking community often achieves this by creating point-to-point guaranteed bandwidth paths. However, the current resource reservation solutions are end-to-end and often initiated by users without the knowledge of the underlying network conditions. As a result, the data flowing through these reserved tunnels are not reusable, and in-network resources are not optimally utilized.On the contrary, Information-Centric Networking architectures such as NDN[16] has several properties that can facilitate resource reservations more intelligently. In this work, we present Strategic Caching And Reservation in ICN (SCARI), a protocol for reserving resources on ICN networks. Similar to RSVP[17] in IP networks, SCARI acts as a signaling mechanism before the actual data transfer. In this work, we focus explicitly on scientific dataflows and not on other types of traffic such as real-time audio/video. We show that SCARI reduces network resource consumption by aggregating reservations and strategically caching content in the network.
