A Survey of Caching Networks in Content Oriented Networks

Abstract

SUMMARY Content oriented network is expected to be one of the most promising approaches for resolving design concept difference between content oriented network services and location oriented architecture of current network infrastructure. There have been proposed several content oriented network architectures, but research efforts for content oriented networks have just started and technical issues to be resolved are still remained. Because of content oriented feature, content data transmitted in a network can be reused by content requests from other users. Pervasive cache is one of the most important benefits brought by the content oriented network architecture, which forms interconnected caching networks. Caching network is the hottest research area and lots of research activities have been published. This paper surveys recent research activities for caching networks in content oriented networks, with focusing on important factors which affect caching network performance, i.e. content request routing, caching decision, and replacement policy of cache. And this paper also discusses future direction of caching network researches. key words: cache networks, content oriented networks, in-network cache

A Survey of Social Network Analysis Techniques and their Applications to Socially Aware Networking

“…Another topic of interest in socially aware networking is content caching. Caching has been getting increased attention as a technology to reduce network traffic and realize efficient content delivery [202,203].…”

“…Content-caching technologies can be categorized into those that cache in the end device and those that cache in the network. Caching in the network is key in content delivery networks (CDNs) [204] and content centric networking (CCN) or named data networking (NDN) [205], and it has been widely studied [202,203,206]. More recently, caching in mobile edges (i.e., small-base stations), also called femtocaching [207], has been getting attention as a key technology in 5G wireless networks [203,[208][209][210].…”

In-Network Caching for Simultaneous Download from Multiple Receivers in Content-Centric Networking

“…Another important research topic in CCN is cache managec 2017 Information Processing Society of Japan ment [13]. The purpose of the cache management is to determine whether a passing data packet is to be cached at each router.…”

“…The purpose of the cache management is to determine whether a passing data packet is to be cached at each router. Some cache management methods such as probabilistic approach, popularity approach, and congestion aware approach, were presented [13]. Among them, our paper focuses on the congestion aware approach.…”

Evolution and Future of Information Networks

“…ICN/CCN provides the content transfer function in a manner similar to that used by Winny, which is a P2P application, or Freenet [36], from which Winny was derived. Specifically, the nodes through which a content request has passed are traced backward, hop by hop, to transfer the requested content to the user while simultaneously storing a copy of the content at each of these nodes [37], [38]. As a result, a number of copies of the content are left on the network so that content can be efficiently delivered to subsequent users from a node close to each user.…”
