信息中心网络 (ICN) 的受欢迎程度和成熟度都在不断增长。 ICN 旗下两个高度相关的架构:内容中心网络 (CCNx) 和命名数据网络 (NDN),在提高其转发性能方面付出了巨大的努力。尽管有这样的关注,但在以全面、严格的方式评估 ICN 转发器方面所做的工作却很少。此外,由于架构之间存在实质性差异,IP 中现有的文献只能广泛应用。在本文中,我们提供了一种分析 ICN 转发器性能的方法。我们的测试方法有两个重点:(i)数据包处理性能是探索的主要指标,因为字节通常很便宜; (ii) PIT、FIB 和内容存储是考虑性能影响时要探测的主要结构。考虑到这些重点,我们提出了一系列行为微基准,可以以严格的方式探测 CCNx/NDN 转发器的性能。为了展示这些实验的有效性,我们将它们应用于CCNx和NDN架构的参考转发器Metis和NFD,让我们仔细了解它们的性能特征。此外,这些微基准应该很容易应用于该领域的高性能转发器。
Information Centric Networking (ICN) is growing in both popularity and maturity. Two highly-related architectures under the ICN umbrella, Content Centric Networking (CCNx) and Named Data Networking (NDN), received significant effort to improve their forwarding performance. Despite this focus, little work has been done to evaluate ICN forwarders in a comprehensive and rigorous manner. Furthermore, the preexisting literature in IP can only apply broadly due to the substantial differences between the architectures.In this paper, we provide a methodology to analyze the performance of ICN forwarders. Our testing methodology has two key focuses: (i) packet processing performance is the primary metric of exploration, as bytes are usually cheap; and (ii) the PIT, FIB, and Content Store are the primary structures to probe when considering performance impact. With these focuses in mind, we present a series of behavioral microbenchmarks that can probe the performance of CCNx/NDN forwarders in a rigorous way. To show the efficacy of these experiments, we apply them to the reference forwarders of the CCNx and NDN architectures, Metis and NFD, giving us a careful understanding of their performance characteristics. Additionally, these microbenchmarks should readily apply to high performance forwarders in the space.
