Analyzing and Correcting Network Performance Problems with perfSONAR

Jason Zurawski, Jeff Boote, Eric Boyd, and Matt Zekauskas, Internet 2, USA


Network capacity and complexity continue to increase. Investment in Research and Educational (R&E) networking has grown considerably due to programs such as the National Telecommunications and Information Administration‚s (NTIA) Broadband Technology Opportunities Program (BTOP). Advancements in network infrastructure have a dual effect. The added investment will facilitate scientific and arts based research, giving access to countless end users and enabling collaboration. Conversely, upgrades and additions to existing infrastructure will introduce flaws through the mixture of heterogeneous equipment, default configurations, and domain specific management.

To make the most of this new investment, network infrastructure should be instrumented and monitored to allow minimal cost of management and to maximize the cost effectiveness. All networks should adopt network performance tools and methodologies to implement this proposed instrumentation. These tools should address all aspects of network performance, including, but not limited to:

  • Identification and collection of several core performance measurements:
    • Latency (Round-Trip and One-Way),
    • Bandwidth (Available, Achievable, etc.),
    • Network Interface Discards, Errors, and
    • Utilization
  • Regular performance monitoring and alarming on the key metrics
  • Use of tools in a methodical, diagnostic fashion to debug problems as they occur

The author of this tutorial will educate attendees on network performance measurement methodologies and tools that have been developed and used by several large R&E networks (ESnet, GÉANT, Internet2, and RNP) to ensure optimal network performance.

This tutorial will provide an in-depth understanding of - what it takes - to provision and manage enterprise applications and services in a Cloud - covering both hands-on technology as well as recent research advancements in these areas. While there are lot of materials available in bits and pieces, there is currently no easy to understand and structured documentation for even the basic building blocks required in a Cloud infrastructure. This tutorial is intended to introduce the audience the state of the art technologies and research for various aspects of an Infrastructure as a Service (IaaS) Cloud platform.

Starting with an overview of current hypervisor and cloud provisioning technologies, various approaches for automated provisioning of single as well as composite virtual appliances will be described. The know-hows for building virtual appliances, managing virtual images will be covered. Several example services will be described for demonstrating the technologies and challenges involved in provisioning the enterprise grade applications in a cloud. Next, the tutorial presenters will cover monitoring and management of services in a cloud to facilitate IT optimization and management simplifications leveraging underlying virtualization based capabilities such as resource elasticity, live virtual machine migration. Various key research challenges and results will be covered related to migration of enterprise applications to the cloud.

Tutorial 4: Friday 13:30-17:00 - Room Beckett 1

Management of Smart Grids: Technologies and Challenges

Dr. Wouter Haerick (IBBT - University of Ghent)
MSc. Matthias Strobbe (IBBT - University of Ghent)


Currently, there is a global consensus to increase energy efficiency, stimulate usage of renewable energy sources, and reduce CO2 emissions. The Smart Grid consists in overlaying the power delivery system with an ICT layer that allows a utility provider and its consumers to constantly monitor and adjust electricity use. Efficient management of such Smart Grids is considered an important research topic for the next years in both academia and industry.

In this tutorial the following aspects will be covered: drivers for Smart Grids, overview of the industrial actors, outline of required underlying ICT architectures, monitoring and management technologies for smart energy grids and identifying the important topics and approaches for further research in this area.

In addition, first results from sociotechnical studies will be presented to provide insight in the user interactions and behavioral response to the envisaged systems, together with some results from business modeling studies to propose the market models enabled/driven by smart energy ICT. In the last part of the tutorial we will present an overview of ongoing standardization efforts and research projects, each with their specific focus.


Wouter Haerick received his Masters degree in Electro-technical Engineering from the Ghent University, Belgium, in June 2001. After graduating, he started working in the telecommunication market and participated in various delivery projects at fixed and mobile operators. In 2004 he joined IBCN as a research assistant and has been involved in various European and national research project such as IST-FP6 MediaNet, FadeHome and QMatch. In 2009, Wouter Haerick obtained a PhD in the field of Computer Science. Wouter Haerick also holds an MBA from the Vlerick Leuven Gent Management school, and is co-founder of two ICT-enabled companies. Currently, WouterHaerick is coordinating the smart grid related research projects. His main research interests are software architectures for deployment of home (energy) services, policy management and wireless QoS.

Matthias Strobbe received his M. Sc. degree in Computer Science Engineering from Ghent University, Belgium, in July 2004. He is now a research engineer and Ph.D student affiliated with the Department of Information Technology of Ghent University. His main research interests include smart power grid algorithms and software architectures for support of context awareness and location based services. He is currently finishing his Ph.D. after which he will work as postdoctoral researcher focusing on smart energy grids.

Interconnecting Service Oriented Domains: Managing Flexible Service Environments for Bi-Directional Service Integration

Thomas Magedanz, Technical University of Berlin, Germany
Lajos Lange, Fraunhofer Institute FOKUS, Germany


This tutorial will provide an overview about the emerging service managing standards as defined in the Open Mobile Alliance (OMA) and TeleManagement Forum (TMF). In this regard we will address in depth the enabling State-of-the-Art, Web-based Information & Communication Technology (ICT) standards, including the Open Service Gateway initiative (OSGi), Service Component Architecture (SCA) and various service composition technologies. In addition, we will introduce the mechanism for bi-directional service integration. This refers to the two approaches "inside-out" based on the internal software export of services (SaaS) and "outside-in" for the external import of Web Services like SOAP, REST, RSS, etc.

The tutorial will also provide an introduction to the designed Service Broker by the authors. This platform is intended for service providers and is part of the Open SOA Telco Playground (www.opensoaplayground.org/Broker). It provides third party developers with a rapid development process by sharing and composing software building blocks efficiently. A proposed service life-cycle management process enables an easy deployment and dynamic service exposure. The integrated policy engine based on open standards assures a controlled access on services and enables a policy based service manipulation, delegation and selection function.

The Service Broker is based on the OMA Service Environment is using the IP Multimedia Subsystem (IMS) ˆ NGN technology while presenting seamless Web/Telco convergence by blending the typical Telco services with Internet services.
