Abstract

With the rapid growth of internet traffic, the traditional host-to-host TCP/IP architecture is subject to many service limitations faced with content-oriented applications. Various novel network architectures have been proposed to solve these limitations, among which Information-Centric Networking (ICN) is one of the most prominent. ICN features the decoupling of content (service) from the physical devices storing (providing) it through location-independent naming, and offers inherent enhancement to network performance, such as multicast and in-network caching. ICN in-network caching has been extensively studied, and we believe that it may also be the main incentive for ISPs to deploy ICN. A CDN (content delivery network) is a typical content-oriented network paradigm that aims to provide the fast delivery of content. In this paper, we leverage the advantages of the in-network caching of ICN to enhance the content delivery efficiency of CDN by integrating ICN as a service. First, we present our design of a content delivery network enhanced with ICN, called IECDN. Additionally, we formulate a mathematical model to optimize the performance of our proposed design and conduct a series of evaluations. The results indicate that our proposed design provides significant performance gains while reducing bandwidth consumption and shows better resilience to traffic surge.

基于 ICN 的 CDN 增强内容交付

随着互联网流量的快速增长，传统的主机到主机 TCP/IP 架构在面向内容的应用中受到了许多服务限制。为了解决这些限制，人们提出了各种新型网络架构，其中最突出的是以信息为中心的网络（ICN）。ICN 的特点是通过与位置无关的命名将内容（服务）与存储（提供）内容（服务）的物理设备解耦，并提供固有的网络性能增强功能，如组播和网内缓存。ICN 的网内缓存已得到广泛研究，我们认为这也可能是互联网服务提供商部署 ICN 的主要动力。CDN（内容交付网络）是一种典型的面向内容的网络范例，旨在提供快速的内容交付。在本文中，我们利用 ICN 的网内缓存优势，通过将 ICN 整合为一项服务来提高 CDN 的内容交付效率。首先，我们介绍了利用 ICN 增强的内容交付网络（称为 IECDN）的设计。此外，我们还建立了一个数学模型来优化所提设计的性能，并进行了一系列评估。结果表明，我们提出的设计在降低带宽消耗的同时显著提高了性能，并对流量激增表现出更好的弹性。
