【摘要】：内容命名网络(NDN)作为ICN的实例系统,以其区别于传统IP网络的独特体系结构在近些年受到了研究界的普遍关注,NDN舍弃了IP网络点到点的传输方式,设计了基于内容名字的寻址方式,使得内容的提供者由集中式一点变为分散式的多点,大幅提高了数据信息的利用率。将研究的重点放在NDN路由节点的转发环节,提出并实现了一种新的基于历史访问记录的转发策略HRF,使得数据请求者能够发现本地的邻居节点是否持有请求者所需的内容,从而从本地网络高效快速地获取所需数据,并通过实验验证了HRF策略的可行性和有效性。
[Abstract]:As an example system of ICN, the content named Network (NDN) has attracted much attention in recent years because of its unique architecture, which is different from the traditional IP network. In recent years, it has been widely concerned that NDN has abandoned the point-to-point transmission mode of IP network.A content-based addressing method is designed to change the content provider from a centralized point to a decentralized multi-point, which greatly improves the utilization rate of data information.Focusing on the forwarding of NDN routing nodes, this paper proposes and implements a new forwarding strategy based on historical access records, which enables the data requester to find out whether the local neighbor node holds the content required by the requestor.In order to obtain the required data efficiently and quickly from the local network, the feasibility and effectiveness of the HRF strategy are verified by experiments.
