喷泉编码已被认为特别适合于有损环境，例如无线网络，因为它提供冗余，同时减少发送器和接收器之间的协调开销。因此，它为多源和/或多播通信提供了有益的特性。在本文中，我们研究提高效率的多源内容交付的内容为中心的网络（CCN）的背景下，使用喷泉码。特别是，我们研究喷泉编码与CCN的网络内缓存功能的结合是否可以进一步提高性能。我们还提出了CCN的兴趣转发机制的增强，旨在最大限度地减少重复传输，可能会发生在一个多源传输的情况下，所有可用的内容提供商和缓存与匹配（缓存）的内容同时传输数据包。我们的模拟表明，在CCN中使用喷泉编码是一种有效的方法，与传统方案相比，进一步提高了网络性能。
Fountain coding has been considered as especially suitable for lossy environments, such as wireless networks, as it provides redundancy while reducing coordination overheads between sender(s) and receiver(s). As such it presents beneficial properties for multi-source and/or multicast communication. In this paper we investigate enhancing the efficiency of multi-source content delivery in the context of Content-Centric Networking (CCN) with the usage of fountain codes. In particular, we examine whether the combination of fountain coding with the in-network caching capabilities of CCN can further improve performance. We also present an enhancement of CCN's Interest forwarding mechanism that aims at minimizing duplicate transmissions that may occur in a multi-source transmission scenario, where all available content providers and caches with matching (cached) content transmit data packets simultaneously. Our simulations indicate that the use of fountain coding in CCN is a valid approach that further increases network performance compared to traditional schemes.
