TUTORIALS
Tutorial T1: Towards Network Innovation through OpenFlow/SDN
Monday, 8:45am-12:15pm, April 16, 2012
Speaker: Masayoshi Kobayashi (Stanford/NEC, USA)
Abstract:
Software-defined networking (SDN) is an emerging paradigm that has been drawing significant interestsboth from industries and academia. SDN provides network owners and operators with more evolvable, flexible networks, in the data center, cellular network, enterprise, and home. Key attributes of SDN include: separation of data and control planes; a uniform vendor-agnostic interface between control and data planes called OpenFlow; a logically centralized control plane; and slicing and virtualization of the underlying network. With an SDN, a researcher or network administrator can introduce a new capability by writing a simple software program that manipulates the flows within a logical slice of the network.
This tutorial consists of two parts. The first part provides an overview of SDN: the concept,various components including OpenFlow switch, OpenFlow protocol, Network OS, control and management application on top, OpenFlow ecosystem (including various vendors and service providers) and OpenFlowdeployment projects in the world (including US GENI project). OpenFlow network in your LabsYou will see some demos (recorded) that demonstrates interesting applications developed in Stanford University and some real-time statistics of OpenFlow network running at Stanford. The second part is a brief introduction of OpenFlow/SDN programming and deployment, where you will learn how to setup an OpenFlow-enabled network on your laptop (using VM), in your Lab or in your campus, and learn how to write a basic application (layer2 learning switch network) with open source OpenFlow controllers. You will also learn some usefulprogramming tools (mininet, OpenFlow wireshark) that helps you to evaluate and debug your OpenFlow/SDN application.
After attending this tutorial, you will understand the concepts of OpenFlow/SDN, various components,and possible research ideas and will have enough knowledge to build your own OpenFlow/SDN networkas well as to start writing your application on top of it.

Speakers: Hideaki Kimura (NTT, Japan), Yukio Ito (NTT Communications, Japan), Keizo Sugiyama (KDDI R&D Laboratories, Japan), Tohru Asami (The University of Tokyo, Japan)
Abstract:
The 2011 earthquake of the Pacific coast of Tohoku and the successive tsunami occurred on March 11th, 2011, which is biggest one in modern era in Japan, disabled the communication infrastructure within Tohoku as well as trunk lines to those areas. We learned various things through this disaster, so we think that we must use this experience to R&D effectively. This tutorial mainly consists of major three parts. 1) Damage and Restoration of Backbone Networks Regarding the Great East Japan Earthquakes, 2) Power Control Technology for Disaster Resistant Base Stations, and 3) Fault Tolerance of Modern Telecommunication Network - Known problems are unsolved yet.
First, this tutorial introduces quake-caused damage situation and how we have done for restoration from the disaster. Especially, telecommunication facilities were suffered large-scale damage by tsunami. Now communication system is a most important lifeline as everyone recognizes, so we must keep communication systems in any situations as a communication career’s mission. This tutorial introduces overview of east Japan earthquake including discovery situation, measures, and future technologies for important 4 research fields related access network technologies such as ‘basic equipment’, ‘optical fibers’, ‘wired transmission’, and ‘wireless transmission’ considering disaster resistance improvement.
Next, this tutorial introduces tribrid power control technology for realizing power supplies that reduce CO2 emissions. This technology enables estimated reductions of 20% to 30% in both commercial electric power consumption and CO2 emissions in base stations and also contributes to deploying disaster-resistant base stations.
Finally, this tutorial quantitatively analyzes the fault tolerance of the today's telecommunication network against this large quake, comparing other social infrastructures, and shows some trivial technologies are not implemented yet, which may increase the service continuity. The issues are launched on failure-resistant networks utilizing their remaining network resources at maximum and providing the services by the same user interfaces as usual even in such a disaster.

Tutorial T4: Model-driven Semantic Management
Monday, 1:45pm-5:15pm, April 16, 2012
Speaker: Joel Fleck II (HP, USA)
Abstract:
The highly adaptive and distributed nature of emerging service delivery environments such as SOA or Cloud SaaS, mean that it is impossible to accurately predict the precise nature of the interactions a software component may be involved in or even the resources that may be used. As a result, management systems cannot reliably have any knowledge of the precise events, entities or actions required to perform management activities. Furthermore, the potential of a large number of widely distributed providers supplying component services and/or resources means that single source management is infeasible. One solution to these challenges is to construct a system of highly federated management environments that are both semantically aware of neighboring environments and use context of federation in management decisions. This tutorial will detail the challenges presented with a highly distributed network of management systems and provide a detailed example of a methodology to build and manage semantic, context-aware inter-domain relationships. It is anticipated that upon conclusion participants will be able to understand the methodology and a sample of tools needed to model a business environment from a consumers perspective, validate semantic integrity of inter-operating business environments, and transform concept maps representing the business perspective into business models, technology neutral architectural models, and technology specific perspectives.

Tutorial T5: Cloud computing for Scalable Network Management
Friday, 8:45am-12:15pm, April 20, 2012
Speaker: Jérôme François (University of Luxembourg, Luxembourg)
Abstract:
Cloud computing offers a smart way to deal with highly resources consuming tasks by leveraging distributed processing on a cluster of machines. Nowadays, such tasks include also network management related ones, especially due to large volumes of network data to deal with and complex operations to achieve for gaining knowledge about data. This tutorial will introduce cloud-computing related paradigms and technologies. In particular, it will focus on Map-Reduce, initially introduced by Google, which the popularity has highly increased recently. Map-Reduce has shift the way to process large volumes of data by executing the code where the data is, and not by downloading the data where the code is. This is very helpful for analyzing large volumes of data like ones generated by network (packet capture, logs, Netflows,...) which may be captured, even in high speed networks, but which the volume limits their analysis. Deep analysis raises important issues. First, this is a task consuming. Thus, the results may be provided too late to be exploited. Finally, large storage space is required since, during the analysis, prior data has to be kept and storing new one is necessary.
