Information-centric networking (ICN) is a new approach to networking contents rather than devices that hold the contents. It has recently attracted much attention of network research and standardization communities. National and multi-national funded research projects have progressed worldwide. International Telecommunication Union -Telecommunication Standardization Sector (ITU-T) started ICN standardization activities in 2012. In parallel, the standards-oriented research cooperation is progressing in the Information-Centric Networking Research Group (ICNRG) of the Internet Research Task Force (IRTF). All these global efforts have been collectively advancing the novel network architecture of ICN. However, there are very few surveys and discussions on the detailed ICN standardization status. To update the reader with information about the ICN research and standardization related activities, this paper starts with the history of global activities on ICN from 2010, giving references to various projects. It then describes the recent progress in the standardization of ICN component technologies in ITU-T and various documents produced by ICNRG. Lastly, it discusses the future directions for progressing ICN.

This document aims at establishing a common understanding about a set of scenarios that can be used as a base for the evaluation of different information-centric networking (ICN) approaches so that they can be tested and compared against each other while showcasing their own advantages. Towards this end, we review the ICN literature and document scenarios which have been considered in previous performance evaluation studies. We discuss a variety of aspects that an ICN solution can address. This includes general aspects, such as, network efficiency, reduced complexity, increased scalability and reliability, mobility support, multicast and caching performance, real-time communication efficiency, energy consumption frugality, and disruption and delay tolerance. We detail ICN-specific aspects as well, such as information security and trust, persistence, availability, provenance, and location independence.

Information-centric networking (ICN) has gained attention from network research communities due to its capability of efficient content dissemination. In-network caching function in ICN plays an important role to achieve the design motivation. However, many researchers on in-network caching have focused on where to cache rather than how to cache: the former is known as contents deployment in the network and the latter is known as cache replacement in an ICN element. Although, the cache replacement has been intensively researched in the context of web-caching and content delivery network previously, the conventional approaches cannot be directly applied to ICN due to the fine granularity of cacheable items in ICN, which eventually changes the access patterns.In this paper, we argue that ICN requires a novel cache replacement algorithm to fulfill the requirements in the design of high performance ICN element. Then, we propose a novel cache replacement algorithm to satisfy the requirements named Compact CLOCK with Adaptive Replacement (Compact CAR), which can reduce the consumption of cache memory to one-tenth compared to conventional approaches.

In this paper we address two of the problems, namely routing and content caching. For the routing problem, we introduce the Potential Based Routing (PBR) which provides not only availability but also diversity and adaptability. In addition, we examine three caching policies to select a possible candidate for ICN. The integrated system of both PBR and a content caching policy is called the Cache Aware Target idenTification (CATT). We present some simulation results to evaluate its performance.
