Authors:Kazumasa Tokuhashi, Takehiro Sato, Kunitaka Ashizawa, Daisuke Ishii, Satoru Okamoto and Naoaki Yamanaka
Title:Extended MPCP Slot Data Transmission Experimental System for Active Optical Access Network
Abstract: Extended MPCP (IEEE802.3av) data transmission experimental system for optical slot-based Access Network is designed. The slot-based two-way communication was successfully established by extended MPCP. The method does not need to analyze frame-header at switch system.

Title: Reducing Network Power Consumption Using Dynamic Link Metric Method and Power Off Links
Abstract:As the high-speed network technologies developing,
the traffic in the Internet increase rapidly. The network power consumption has come up to 10% of the worldwide energy consumption. In order to reduce this kind of consumption, we propose a novel method, which dynamically modifies the weights of links and makes traffic gather to certain links and then set some links of which the load no traffic Powe-Off. We also did much work in the network simulations, and the result shows that the method has a good effect in reducing the network power consumption.

MR. TOKUHASHI’S PAPER REGARDING WITH DYNAMIC PACKET (FRAME) BASED RANGING METHOD FOR ACTIVE OPTICAL ACCESS NETWORK WAS PUBLISHED IN JOURNAL OF IEICE(AUG. 2010).

Mr. Tokuhashi’s letter regarding with  Active Optical Access Network was published in Journal of IEICE(Aug. 2010)

title:Dynamic Packet (Frame) Based Ranging Method for Active Optical Access Network
authors:Kazumasa TOKUHASHI, Kunitaka ASHIZAWA, Daisuke ISHII, Yutaka ARAKAWA, Satoru OKAMOTO, and Naoaki YAMANAKA
abstract:In an active optical access network with high-speed optical switches, a precise ranging method adopting dynamic packet (frame) is proposed. In the experiment using our developed prototypes of OLT, ONUs and a switch emulator, a dynamic packet based ranging method between OLT and ONUs was successfully executed.”,”

MR. TOKUHASHI WAS GIVEN AN AWARD TO AT THE CEREMONY OF “SENTAN GIZYUTSU AWARDS”.

Mr. Tokuhashi was given an award to at the ceremony of “Sentan Gizyutsu Awards”.

These awards are prestigious awards for students in the science and engineering majors and young researchers in Japan.
“Sentan Gizyutsu” means “high technology/advanced technology”.

Mr. Tokuhashi was with a special award for his achievements in the next generation optical access network system using ultra high-speed PLZT optical switches.
