In Information-Centric Networking (ICN), consumers send interest packets to the network and receive data packets as a response to their request without taking care of the producers, which have provided the content, contrary to conventional IP networks. ICN supports the use of multiple paths; however, with multiple consumers and producers, coordination among the nodes is required to efficiently use the network resources. Network coding (NC) is a promising tool to address this issue. The challenge in the case of NC is to be able to get independent coded content in response to multiple parallel interests by one or several consumers. In this work, we propose a novel construction called MILIC (Multiple Interests for Linearly Independent Contents) that impose constraints on how the replies to interests are coded, intending to get linearly independent contents in response to multiple interests. Several protocol variants, called MICN (MILIC-ICN), built on top of NDN (Named Data Networking), are proposed to integrate these interest constraints and NC of data packets. Numerical analysis and simulations illustrate that the MILIC construction performs well and that the MICN protocols are close to optimal throughput on some scenarios. MICN protocols compare favorably to existing protocols and show significant benefits when considering the total number of transmitted packets in the network, and in the case of high link loss rate.

MICN：ICN 的网络编码协议，每一代都有多个不同的兴趣

在以信息为中心的网络 (ICN) 中，消费者向网络发送兴趣包并接收数据包作为对他们请求的响应，而无需照顾提供内容的生产者，这与传统的 IP 网络相反。ICN 支持使用多条路径；然而，对于多个消费者和生产者，需要节点之间的协调才能有效地使用网络资源。网络编码 (NC) 是解决此问题的有前途的工具。在 NC 的情况下，挑战是能够获得独立的编码内容，以响应一个或多个消费者的多个并行兴趣。在这项工作中，我们提出了一种称为 MILIC（线性独立内容的多重兴趣）的新结构，它对兴趣的回复如何编码施加限制，打算获得线性独立的内容以响应多种兴趣。提出了几种协议变体，称为 MICN (MILIC-ICN)，建立在 NDN（命名数据网络）之上，以集成这些兴趣约束和数据包的 NC。数值分析和仿真表明，MILIC 结构表现良好，MICN 协议在某些场景下接近最佳吞吐量。MICN 协议与现有协议相比具有优势，并且在考虑网络中传输的数据包总数时以及在高链路丢失率的情况下显示出显着的优势。数值分析和仿真表明，MILIC 结构表现良好，MICN 协议在某些场景下接近最佳吞吐量。MICN 协议与现有协议相比具有优势，并且在考虑网络中传输的数据包总数时以及在高链路丢失率的情况下显示出显着的优势。数值分析和仿真表明，MILIC 结构表现良好，MICN 协议在某些场景下接近最佳吞吐量。MICN 协议与现有协议相比具有优势，并且在考虑网络中传输的数据包总数和高链路丢失率的情况下显示出显着的优势。
