Journal ArticleDOI
Network performance and integrity enhancement with optical path layer technologies
TL;DR: The optical path layer concept proposed exploits and consolidates the layered transport network architecture and optical technologies, and will open up new opportunities for creating a B-ISDN that is bandwidth abundant and has a high degree of integrity.
Journal ArticleDOI
Optical path cross-connect node architectures for photonic transport network
TL;DR: In this paper, the authors explored the optical path cross-connect (OPXC) node architectures that are essential components of the OPXC, which handles optical paths, is constructed with an optical switching network.
Journal ArticleDOI
GMPLS-based photonic multilayer router (Hikari router) architecture: an overview of traffic engineering and signaling technology
Ken-ichi Sato,Naoaki Yamanaka,Yoshihiro Takigawa,M. Koga,Satoru Okamoto,Kohei Shiomoto,Eiji Oki,Wataru Imajuku +7 more
TL;DR: A heuristics-based multilayer topology design scheme that uses IP traffic measurements in a generalized multi-protocol label switch (GMPLS) that yields the optical label switch path (OLSP) network topology, that is, OLSP placement, that minimizes network cost in response to fluctuations in IP traffic demand.
Journal ArticleDOI
Optical path cross-connect system scale evaluation using path accommodation design for restricted wavelength multiplexing
TL;DR: Novel OP accommodation design algorithms that can heuristically establish wavelength paths or virtual wavelength paths (VWPs) in the network, where each link is composed of multiple fibers are proposed.
Journal ArticleDOI
No clear-cut evidence for cadmium-induced renal tubular dysfunction among over 10,000 women in the Japanese general population: a nationwide large-scale survey
Takafumi Ezaki,Teruomi Tsukahara,Jiro Moriguchi,K. Furuki,Yoshinari Fukui,Hirohiko Ukai,Satoru Okamoto,Haruhiko Sakurai,Sumihisa Honda,M. Ikeda +9 more
TL;DR: No clear-cut evidence was obtained in the present study to show that environmental exposure to Cd has induced tubule dysfunction among middle-aged women in the general population in Japan.
