DENA: An Intelligent Content Discovery System Used in Named Data Networking

摘要: Named data networking (NDN) aims at efficient content delivery and reducing the redundancy of transmission. In NDN, one most important issues is how to utilize cached contents reduce user's response delay improve utilization cache resources. this paper, an intelligent discovery system fully resources, called DENA, proposed, which encompasses deep exponential network-based announcement exergy-based replacement algorithms. DENA provides shortcut paths for interest packets access targeted under instructions AT (announcement table) constructed by a precision algorithm with low communication overhead. meantime, assist also proposed. The method uses so-called exergy index instruct content. simulation results indicate that improves resources network capacity while keeping control traffic relatively level.
