Information-centric networking (ICN) provides request aggregation and caching strategies that can improve network performance by reducing content server loads and network traffic. Incorporating network coding into ICN can offer several benefits, but a consumer may receive the same coded block from multiple content routers since the coded block may be cached by any of the content routers on its forwarding path. In this paper, we introduce a request-specific coded-block scheme to avoid linear dependency of blocks that are utilizing in-network caching. Additionally, a non-cooperative coded caching and replacement strategy is designed to guarantee that the cached blocks can be reused. Our experimental results show that the proposed scheme has superior performance to conventional CCN and two network coding-based ICN schemes.

以信息为中心的网络中的高效编码块传递和缓存

以信息为中心的联网（ICN）提供了请求聚合和缓存策略，这些策略可以通过减少内容服务器负载和网络流量来提高网络性能。将网络编码合并到ICN中可提供多种好处，但是由于编码块可能被其转发路径上的任何内容路由器缓存，因此消费者可能会从多个内容路由器接收相同的编码块。在本文中，我们介绍了一种特定于请求的编码块方案，以避免利用网络内缓存的块的线性依赖性。此外，还设计了一种非合作的编码缓存和替换策略，以确保可以重用缓存的块。我们的实验结果表明，该方案具有优于常规CCN和两种基于网络编码的ICN方案的性能。
