Feature Articles: Movable and Deployable ICT Resource UnitĄ˝Architecture for Quickly Responding to Unexpected ICT Demand-
 Overview of Movable and Deployable ICT Resource Unit Architecture
Abstract
When the Great East Japan Earthquake struck in 2011, a lot of the information and communication technology (ICT) infrastructure suffered catastrophic damage, which triggered ICT service outages in various areas for long periods of time. NTT Network Innovation Laboratories has been working to solve this problem and has developed ICT architecture called the Movable and Deployable ICT Resource Unit (MDRU). This architecture enables us to instantly deliver ICT services in damaged areas by installing a transportable ICT unit that accommodates the equipment necessary for providing ICT services. This article presents an overview of the MDRU architecture and also introduces a research and development project launched to realize it.

Wireless Access Network System Using M2M Wireless Access for MDRU
Abstract
NTT Network Innovation Laboratories has been developing the Movable and Deployable ICT Resource Unit (MDRU) that enables us to quickly reestablish information and communication technology (ICT) services in disaster-stricken areas. In this article, we introduce a novel MDRU radio function that constructs a Wi-Fi access network quickly and flexibly around the MDRU by using machine-to-machine wireless access as the control link.

High-speed and Plug-and-play Optical Interconnection for MDRUs
Abstract
After a Movable and Deployable ICT Resource Unit (MDRU) is installed and local ICT (information and communication technology) services are established in a disaster-affected area, reestablishing communication service between the disaster-affected area and undamaged areas will be strongly desired by the people in the disaster-affected area. We propose to establish a communication link between the MDRU and the backbone network by connecting 100-Gbit/s digital coherent transponders to the ends of undamaged underground optical cable.

A Media Storage and Transmission System Using MDRUs
Abstract
Developing information and communication technology (ICT) networks and services that are resilient to disasters is a critical task. NTT Network Innovation Laboratories is promoting innovative research and development on a transportable ICT node called the Movable and Deployable ICT Resource Unit (MDRU), which is designed to promptly recover ICT services after a disaster. In this article, we introduce a media storage and transmission system based on the use of MDRUs. It efficiently provides information such as text and image/video data to people in disaster areas in circumstances when ICT resources are constrained such as when network bandwidth is limited or storage failures occur. We demonstrated its feasibility in a field trial.

ICT Service for MDRUs
Abstract
In this article, we describe an Internet protocol (IP) phone service system and an evacuee management system that were developed as information and communication technology (ICT) services for Movable and Deployable ICT Resource Units (MDRUs) to assist in recovery after large-scale disasters. Deploying an MDRU with IP-PBX (IP-based private branch exchange) functionality to the affected areas makes it possible to immediately provide IP phone services via Wi-Fi. The evacuee management system proposed here enables the efficient collection of evacuee data in evacuation centers.

Overseas Deployment of MDRU: ITU Project in the Philippines, and MDRU Standardization Efforts
Abstract
The network facility at the San Remigio municipality on Cebu Island in the Philippines sustained enormous damage from super typhoon Haiyan in November 2013. NTT Network Innovation Laboratories, NTT Communications Corporation, and partners initiated a feasibility study on restoring telecommunication and information and communication technology (ICT) infrastructure damaged by typhoon Haiyan through the use of the Movable and Deployable ICT Resource Unit (MDRU), under cooperation between the Ministry of Internal affairs and Communications of Japan, the Department of Science and Technology of the Philippines, and ITU (International Telecommunication Union). We report on this feasibility study in this article. We also introduce the work being done to standardize the MDRU by NTT Network Innovation Laboratories.

InP-based Membrane Optical Devices for Large-scale Photonic Integrated Circuits
Abstract
Large-scale photonic integrated circuits for telecom and datacom applications have attracted attention for many years. We have developed III-V based membrane optical devices employing lateral p-i-n junctions with buried heterostructures. This article introduces lateral current injection lasers and modulators integrated on an InP substrate and membrane lasers on a SiO2/Si substrate as promising building blocks of integrated transmitters.

W3C TPAC 2014 Report and HTML5 Recommendation
Abstract
The W3C (World Wide Web Consortium) Technical Plenary / Advisory Committee Meetings Week (TPAC) was held from October 27 to 31, 2014, in Silicon Valley in the USA. The year 2014 was not only the 25th anniversary of the creation of the web but also the 20th anniversary of the foundation of W3C. On October 28, the W3C published a formal Recommendation of HTML5 (HyperText Markup Language, fifth revision) during TPAC in this anniversary year. In this article, we report on W3C TPAC 2014 and the HTML5 Recommendation.
