  Overview
  Combating malware has become a global issue. The black market for malware, which threatens the integrity of even state secrets, is turning into a robust organization that presents an ongoing challenge to researchers. Since 2005, when the word malware came into common use, NTT Secure Platform Laboratories has been working around the clock to collect, analyze, and combat malware. We asked Dr. Makoto Iwamura, NTT Distinguished Researcher, to tell us about research achievements to date, future issues, and approaches to establishing an anti-malware system and training program for security personnel.

• Approach to Network Science―Solving Complex Network Problems through an Interdisciplinary Approach

  

  Abstract
  As networks come to be used in diverse ways and become increasingly complex and massive in scale, it is becoming difficult to support networks using only existing network technologies aimed at achieving complete control of individual network elements. At NTT Network Technology Laboratories, we are researching and developing network science as an interdisciplinary approach that combines existing network technologies with new technologies from other fields. We are also carrying out research and development (R&D) on technologies that apply network science to enable service providers and end users to use networks in more intelligent ways. This article provides an overview of these R&D efforts at NTT.

• Basic Theory of Network Science―the Network, Spatial Characteristics, and Spatial Information

  

  Abstract
  NTT Network Technology Laboratories is researching a new theory to support networks that focuses on spatial information handled by networks. This article discusses an evaluation of geometric probability based on integral geometry and the design and control of new network characteristics.

• QoE-centric Operation for Optimizing User Quality of Experience

  

  Abstract
  NTT Network Technology Laboratories has been researching indices for evaluating user quality of experience (QoE) for a variety of services. Our aim is to achieve QoE-centric operation for optimizing QoE using information that can be monitored during the provision of services. This article introduces the elemental technologies of QoE-centric operation.

• Proactive Network Control

  

  Abstract
  Development of virtualization technologies has enabled proactive network control and flexible resource optimization, which promise to help preempt reductions in service quality due to congestion and to increase network utilization rates. In this article, we introduce a method of traffic prediction that considers the mechanisms causing the traffic, and a means of control that is tolerant of unpredicted traffic, contributing to proactive network control.

• Analytics-based Operation for Implementing Service Co-creation Networks

  

  Abstract
  At NTT Network Technology Laboratories, we are working on ways to accelerate the speed of responding to network faults, as well as to increase accuracy and save labor when doing so. This includes analyzing data obtainable within and outside the network such as equipment logs, traffic, and trouble tickets, in order to achieve service co-creation networks. A key method to achieve this is analytics-based operation, which we introduce in this article.

Global Standardization Activities

• Report of ASTAP-25 and 1st APT Preparatory Meeting for WTSA-16

  

  Abstract
  The 25th meeting of the Asia-Pacific Telecommunity (APT) Standardization Program (ASTAP), which refers to the regional standardization activities of APT, was held in Bangkok in March 2015. This article reports the major outcomes of this ASTAP meeting, including the new structure of ASTAP, results of discussions on networks and systems, which are of interest to telecom operators, and the preparatory activities for the WTSA (World Telecommunication Standardization Assembly) meeting to be held in 2016.
