Presentation Title: NEDO Project on Development of Next-Generation Highly-Efficiency Network Device Technology - Project Status Towards Energy Saving -

Presentation file (pdf)

Abstract: This paper shows the interim report of the development project on Next Generation Highly Efficient Network Technology, sponsored by New Energy and Industrial Technology Development Organization (NEDO), in the fiscal years from 2007 to 20011. The project aim is to develop high speed and energy-saving devices as well as traffic control technologies to satisfy the demands of telecommunication service as the infrastructure for the future information society. Three classes of energy saving are investigated: (1) Optical transmitter/receiver, (2) Switch backplane, (3) OTDM-NIC for Optical Path Switching. The first one is to reduce the power of 100GE and 40GE optical transceiver and receiver, each of which runs with 10mW/Gbps(25Gbps). The second is to replace the electrical backplane with 25Gbps-based optical links. The third class is to develop 160Gbps OTDM-NIC for Optical Path Switching to replace a packet switching module.

Presentation Title: Greening the Enterprise & Datacenters

Presentation file (pdf)

Abstract: Reducing the energy consumption of PCs and servers is becoming increasingly important with rising energy costs and environmental concerns. In enterprise networks, idle desktop machines rarely sleep, because users and IT departments want them to be always accessible. In mega datacenters the energy cost can have a crippling effect on the business model. I will discuss some on-going work in Microsoft Research that aims at reducing PC energy and server energy usage in the large and small enterprises. Specifically, I will discuss (a) Somniloquy, a hardware architecture that augments network interfaces allowing PCs that are in suspend to RAM sleep state to be responsive to network traffic; (b) a Sleep Proxy system, that has been deployed in Microsoft Research and has been operational for over 6 months (c) JouleMeter, a tool that shows the breakdown of the application energy usage by individual components (disk, CPU, memory) for regular PCs, and (d) Widsom, centralized request routing scheme that optimizes the performance and energy cost of large scale cloud services. I will share some lessons learnt.

Presentation Title: Green-City Transport Architecture: Closing the loop between sensors, navigators, and routes

Presentation file (pdf)

Abstract: The major drivers of intelligent transport systems in recent years have been increased safety, improved traffic flow, and reduced fuel consumption and emissions ? with considerable success in each area. On a per passenger mile basis, traffic injuries and deaths are down significantly over the past 20 years, as are fuel consumption and emissions. These improvements, however, have been eroded significantly by the growth in population and the absolute scale of travel. Despite the higher vehicular safety and efficiency, the performance of vehicle systems is by many measures declining, especially in cities. Traffic congestion in U.S. metropolitan areas large and small is up dramatically over the past two decades, with negative effects on economic productivity, fuel consumption and air pollution. Our increasingly efficient vehicles are growing more "intelligent" than the road systems on which they operate. In this study we focus our attention on intelligent metropolitan traffic management with the aim of reducing congestion, pollution and traveler delays, and in the process also improving fuel consumption and emissions. Up to now, metropolitan traffic control has been implemented by rather elementary means: traffic signal controls based on local information (video cameras, sensor loops), congestion fees based on historical traffic data, and so on. But recent advances in communications, navigation, and sensor technologies present new opportunities to increase the intelligence and efficiency of metropolitan streets and highway networks. The pivotal element of intelligent transport architecture is the ability to "close the loop" between on-board sensors of road and vehicle conditions on one hand, and traffic management tools (signals, real-time information signs, variable tolls, etc.), traffic enforcement, and car navigators on the other. Keys to closing the loop are on-board navigators, navigation servers, and intelligent traffic signals. The signals control vehicle flows at intersections and interact with vehicle components (such as ignition systems) and vehicle sensors (collecting data on position, speed, emissions, etc.), which broadcast data to on-board navigators. The navigator server interacts with central traffic controllers and proposes optimal routes to the on-board navigators. In this project we will design an urban traffic management system that receives inputs from vehicles (e.g., sensor readings, position, preferences, etc), processes these inputs to generate a routing plan, and then implements the plans through navigators and traffic signals. Using the system proposed here, metropolitan traffic management will evolve to become a more sophisticated control system where "cyber intelligence and complexity" interacts with "physical" elements on board the vehicles. At the top state, regional and local traffic managers work with navigator servers to implement policies and optimize routing. In the middle, the traffic signals monitor the on-board environment sensors and broadcast local route advisories. At the bottom, the on-board navigator implements the routing instructions from navigator server and traffic signals. All this is made possible by effective vehicle to infrastructure communications, from 3G channels to (on-board/roadside) DSRC communications that enable real time, low cost, scalable information exchanges among the various architecture omponents. The overarching goal of this project is to develop a vehicular traffic monitoring and control system ? termed Green-City Transport Architecture ? that uses (a) the sensors and actuators available on the vehicle, (b) the vehicle communications infrastructure, and (c) a set of powerful traffic, congestion, and air quality modeling tools to carry out both short-term vehicular traffic routing/assignment and longer-term traffic planning. This project will be highly interdisciplinary; it will benefit from the collaboration and expertise of atmospheric science researchers, auto manufacturers, traffic signalization and control engineers, and vehicle navigation developers. The efficacy of our solution will be demonstrated via simulation, emulation, and small scale experimentation on a Campus Vehicular Test bed (CVET).

Presentation Title: Sustainable Computing

Presentation file (pdf)

Abstract: "Sustainability" has been interpreted in many ways. In strict terms, sustainability implies consuming [natural] resources at a slower pace that with which they can be replenished. In more complex interpretations, it can encompass overlapping domains of economics, environment, and society. A simple definition used by both the United Nations Environment Programme and the International Union for Conservation of Nature is, "improving the quality of human life while living within the carrying capacity of supporting eco-systems."
Many factors effect the level of sustainability that a given IT organization can realize within their data centers. Reducing electrical consumption is paramount, but only a single aspect of eco-efficiency. In this panel presentation, we look at strategies beyond cooling efficiencies and power conservation that can be leveraged by organizations wishing to take a more holistic approach to sustainability. These strategies range from purely technical through to the business' operation and culture.
