Title：Novel Scheduling Method to Reduce Energy Cost by Cooperative Control of Smart Houses Abstract：A smart house which equips power generators, power storage systems, and a smart meter which controls those equipments to utilize renewable energy efficiently has attracted attentions. Smart house is expected to reduce energy cost of residential by efficient usage of energy resources. Scheduling methods of the equipments to reduce energy cost have been proposed. However, since hey focus on only one house, the effect of the scheduling decreases due to the imbalance of the equipments and the concentration of selling energy to power grid at same time. This paper proposes a new scheduling method to operate multi-smart houses totally by virtually sharing their equipments. The proposed method can improve the imbalance of the equipments and reduce the amount of disposal energy. By computer simulation, it is shown that the proposed method can reduce over 16 % the energy cost to the conventional method.

Title： Dynamic Transmission Route Selection Towards the Contents Transmission Energy Optimization in E3-DCN
Abstract：We previously proposed Energy Efficient and Enhanced-type DCN(E3-DCN) which includes mash-up
service and Data Centric Network(DCN) and transmission energy efficiency. Mash-up service is the cloud service which combines devices, softwares, and contents on network. In the DCN, users request contents names to the network and receive requested contents from the network. E3 -DCN is built on the NeW Generation Network(NWGN), and aims at transmission energy optimization. In this paper, we propose the dynamic transmission route selection system in consideration of future traffic states. The simulation using Integer Linear Programming(ILP) shows the validity of this proposed system. And, we also introduce an experiment of a power saving mash-up service type contents distribution system.

Title： EDA-based Charging Algorithm for Plug-in Hybrid Electric Vehicle to Shift the Peak of Power Supply
Abstract：This paper proposes a charging algorithm which is based on the Estimation of Distribution Algorithm
(EDA) for Plug in Hybrid Electric Vehicle (PHEV). The proposed algorithm shifts the peak of power supply, satises the requested State of Charge (SoC [%]), and minimizes the charging cost. The proposed algorithm uses exible weight for charging and upper charging limit to each PHEV to minimize the charge amount in peak time. The simulation result shows that the proposed algorithm shifts the peak of power supply in commute time zones, satises SoC of 93% PHEVs, and reduces charging cost by 31% compared with conventional EDA algorithm.

Mr. Kikuta’s paper regarding with an experiment of P2MP VLAN path establishment on GMPS-controlled wide area Ethernet is accepted in a journal of IEICE Transactions on Communications.

Title: Experiment of Point-to-Multipoint VLAN Path Establishment on the overlay-model-based GMPLS-controlled Wide Area Ethernet
Authors: Ko KIKUTA, Daisuke ISHII, Satoru OKAMOTO, Naoaki YAMANAKA

Abstract: We report the first successful experiment on Point-to-
Multipoint (P2MP) VLAN path establishment on the overlay-model-based
GMPLS-controlled wide area Ethernet. To support the overlay model,
P2MP VLAN path signaling with egress output port indication is proposed
and implemented. It is confirmed that our extended RSVP-TE software can
correctly establish P2MP VLAN paths in the overlay-model network.

We have successfully closed iPOP 2012 7th International Conference/Exhibition on IP Optical. This year gathering about 300 participantsthat is world record of iPOP from US, Europe, China, Korea and Japan.This year we are starting to expand our categories to cloud interworking and SDN. Because IP/optical network transport technologies will good meet to dynamic inter cloud architecture. In addition, iPOP have been leading with controlling technology based on D/C separation network architecture. So this year we world first interworking by SDN and control SDTN(Transport) under multi-AS Multi-vendor and Multi-technology network.
Anyway, Let me thank you all for your kind support and donation for children on behalf of the committee. At the conference, we mentioned that more than 200 children, expected to success in the future, has given up hope to continue their education due to the earthquake disaster last year, and asked for donations in participation fee for the reception. Fortunately, we were able to donate 67,895 yen to the Japanese nonprofit organization Ashinaga (“long-legs”). I hope we can save those children that are forced to abandon their dream to earn a living as much as possible! Thank you very much.

Title: Future Service Adaptive Access/Aggregation Network Architecture
Authors: Hiroki IKEDA Hidetoshi TAKESHITA Satoru OKAMOTO
Abstract: The emergence of new services in the cloud computing era has made smooth service migration an important issue in access networks. However, different types of equipment are typically used for the different services due to differences in service requirements. This leads to an increase in not only capital expenditures but also operational expenditures. Here we propose using a service adaptive approach as a solution to this problem. We analyze the requirements of a future access network in terms of service, network, and node. We discuss available access network technologies including the passive optical network, single star network. Finally, we present a future service adaptive access/aggregation network and its architecture along with a programmable optical line terminal and optical network unit, discuss its benefit, and describe example services that it would support.
