Network Technology Development for Digital Society of theFuture▼Abstract

As society moves toward digitization, the network supporting a digital society must likewise evolve. NTT has
taken up the research and development (R&D) of a network infrastructure called Cognitive Foundation® inorder to solve a wide variety of problems in our digital society. This article introduces specific R&D
achievements based on the following R&D directions of network technology for the future digital society: (1)R&D of competitive network infrastructure technologies, (2) advanced and smart network operation
supporting digital transformation of the NTT Group, and (3) global environmental protection and optimal useof energy.

Global Standardization Activities

Versatile Video Coding: a Next-generation Video CodingStandard▼Abstract

The scope of Subcommittee (SC) 29 of ISO/IEC (International Organization for Standardization/InternationalElectrotechnical Commission) Joint Technical Committee 1 is coding of audio, picture, multimedia, andhypermedia information. Working Group (WG) 11, part of SC 29, is standardizing video coding, media
transmission, streaming, audio coding, image/video retrieval, and genomic information coding. In April
2018, WG 11 initiated standardization of next-generation video coding called Versatile Video Coding (VVC),
which is aimed at achieving higher compression, in conjunction with ITU-T (International Telecommunication
Union - Telecommunication Standardization Sector) Study Group 19. This article introduces thebackground, target, and recent development status of VVC.

World’s Fastest 600-Gbit/s per Lambda (λ) Optical Transmission with 587-Gbit/s Data Transfer—
Prospect for Realizing 600-Gbit/s/λ Optical Network and Data Transfer Protocol

As wireless local area network (LAN) communication becomes more popular, the number of failures isincreasing and the causes of failure are becoming more diverse. This article introduces two cases
concerning problems with wireless LAN caused by IP (Internet protocol) packets and a wireless encryption
scheme. This is the fifty-second article in a series on telecommunication technologies.
