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 paper describes a new network architecture for personal communication services that provides transparent connectivity to different physical networks. We call this system DUET (Distributed User‐agent for Easy Telecommuication). In this system both user information and customized service logic are managed independently by a distributed personal agent (PA) that is identified by the personal ID. The location information of users and terminals is managed by distributed area agents (AAs). Each PA interacts with other PAs and AAs to support flexible person‐to‐person communications in a heterogeneous network environment including mobile terminals. © 1997 Scripta Technica, Inc.
