Title：Ultra High Speed Wavelength Selective Switching Technique for Optical Aggregation Network

Abstract：The Internet is composed by many routers. On the other hand, energy consumption of all routers in the Internet is an important problem. Because of increasing the transmitting speed, it reached 7.3TW/h in 2008, and now, it reaches 13TW/h in 2010. Thus, we have proposed the Optical Aggregation Network which aggregates many routers into one cloud router and creates a simple tree-based network for reducing the energy consumption of all routers intensively for saving earth.
In this presentation, we propose ecological scalable WDM Network by using PLZT optical WSS (Wavelength Selective Switch) for implementing the Optical Aggregation Network. This PLZT WSS has slot switching function. Therefore, it could extend the distance of network and could add more subscribers to implement ecological scalable network.

Title:A Study on Intermediate Network Structure between Data Centers for a Intelligent Cloud Network using Parallel Transmission System

Abstract:With the appearance of the cloud network, high speed data communication among data centers is necessary. However, because the data is transmitted through the Internet, network bandwidth is not enough. To construct large bandwidth WAN at low cost, we propose an Intelligent Cloud Network. In the Intelligent Cloud Network, data delivered with parallel transmission and lower cost private lines that are lower bandwidth are applied as multiple routes. In this paper, we propose parallel transmission system. In this system, parallel routes are set up with GMPLS. The proposed system is implemented on the software switch to evaluate parallel transmission.

Title： Study on the Virtual Machine Migration Scheme for the Realization of Follow the SUN Data Center
Abstract：Recent years, the power supply becomes a problem because the number of users of the data center increase rapidly as cloud computing develops. In the world wide trend getting rid of fossil fuel and nuclear energy, it is hoped to use the photovoltaic power generation which is natural energy effectively. But, it is impossible to provide services at nighttime. By moving virtual machines according to the motion of the sun, the photovoltaic natural energy can be used effectively. Then, we aim at the realization of Follow the SUN Data Center which sends and receives virtual machines between geographically away data centers. In this paper, we consider the virtual machine migration scheme using existing techniques which solve the communication continuity problem between user and virtual machine. Also, we compare existing techniques, and we consider the possibility of realizing Follow the SUN Data Center.
