پشتیبانی از تحرک بدون درز برای برنامه های کاربردی در زمان واقعی در شبکه داده نامیده می شود

Named Data Networking architecture originally provided consumer mobility by design, however content or producer mobility was left unspecified. Since then a number of producer mobility support schemes have been proposed. In this paper, we provide a survey on the most relevant proposed techniques to support mobility in NDN. We classify these mobility support techniques into categories based on their underlying mechanisms of explicit notification, routing, indirection, mapping, and proactive caching. We discuss their strengths and weaknesses, and investigate their appropriateness to accommodate real time requirements necessitated by most of today traffic.
