Abstract This article introduces some of the latest research topics related to new optical fiber technologies. These technologies enable functional and efficient operation and maintenance of networks while maintaining high reliability, and will support future high-speed, high-capacity networks. The Feature Articles in this month's issue are based on lectures given at the NTT Tsukuba Forum 2012 workshop held on October 19, 2012.
Abstract NTT Access Network Service Systems Laboratories is working on the Civil Systems Project, which involves conducting research and development (R&D) on infrastructure facilities such as conduits and manholes. This article reviews the current state of infrastructure facilities, provides details of our current R&D, and touches on future developments. This article is based on a lecture given at the NTT Tsukuba Forum 2012 workshop held on October 19, 2012.
Abstract NTT Secure Platform Laboratories has been researching and developing incident responses for when disasters occur. We introduce the approaches to incident response taken in the United States and compare them with those in Japan. We also introduce the disaster management standard ISO 22320: Societal security°›Emergency management°›Requirements for incident response, issued by the International Organization for Standardization (ISO) in November 2011.
Abstract Character encodings are a basic and fundamental layer of digital text that are necessary for exchanging information over the Internet. Character codes are used in plain text file as well as in structured text files such as XML (extensible markup language), MIME (multipurpose Internet mail extensions), and HTML (hypertext markup language).
This article explains the basic architecture of character encodings and reviews Japanese and International standardization activities.
