摘　　要：作为一种新型网络架构,信息中心网络(ICN)将通信模式从以主机为中心转变为以信息为中心,彻底改变了内容检索和传输的方式。信息中心网络将内容的标识符和定位符解耦,并支持广泛的网内缓存,用户可根据内容的名称从不同的内容源获取相应的数据。因此,信息中心网络的数据检索和传输具有多源和多路径的特点。本文对信息中心网络的多路径传输机制进行了充分的调研。本文首先从网络层和传输层的角度介绍了传统TCP/IP网络的多路径传输技术,然后详细阐述了不同ICN范式的多路径传输技术,包括转发策略和拥塞控制策略,最后对ICN多路径传输的未来研究方向进行了总结,为后续的研究者提供参考。As one of the candidates for future network architecture,Information-Centric Networking(ICN)has revolutionized the manner of content retrieval by transforming the communication mode from host-centric to information-centric.ICN decouples content identifiers and locators and supports extensive intranet caching.Users can obtain data from multiple content sources according to the content name.Therefore,the transmission in ICN has the characteristics of multisource and multipath.In this paper,we have fully investigated the multipath transmission mechanism for ICN.We first introduced the multipath transmission mechanism of traditional TCP/IP networks from the perspective of network layer and transport layer,and then we analyzed the multipath transmission mechanism of different ICN paradigms,including forwarding strategy and congestion control strategy,and finally we described the possible future research direction of ICN multipath transmission to provide references for subsequent researchers.
