面向内容迁移的移动切换方法
首发时间:2019-08-12
摘要:信息中心网络(ICN)是一种以信息为中心,采用内容名称作为网络传输标识的网络结构,能够满足人们对以信息为中心的通讯方式的需求。ICN网络中面向内容迁移是研究热点,尤其对于某些实时应用程序(例如视频通话),由于这些应用程序的内容是在线生成的,并且无法提前推送,导致这种问题更为突出。本文针对服务于实时应用程序的内容移动后内容不可达,内容请求时间长这一问题,提出了一种面向内容迁移的移动切换方法,以此来解决实时应用程序内容迁移后内容不可达,内容请求时间长这一问题。最后本文将提出的解决方法在NDNSIM仿真平台上进行模拟实验,通过实验表明本文提出的方法可以缓解由于内容迁移所造成的高延迟和内容不可达问题。

Mobility Switching MethodD For Content Migration
Abstract:Information center network (ICN) is an information-centered network structure with content name as the network transmission identifier, which can meet people\'s demand for information-centered communication. Content-oriented migration is a hot topic in ICN networks, especially for some real-time applications (such as video calls), where the content is generated online and cannot be pushed in advance. In this paper, a content migration oriented mobile switching method is proposed to solve the problem of unreachable content and long request time after the content serving real-time applications is moved. Finally, the solution proposed in this paper is simulated on the NDNSIM simulation platform. The experiment shows that the method proposed in this paper can alleviate the problems of high latency and unreachable content caused by content migration.
