Panel 1: Web-Services for Internet Management: Yet Another Hype?
Chair: Aiko Pras, University of Twente, THe Netherlands

Web-services for Internet management: yet another hype?
At every past IM there has been a panel to discuss which new technology
would replace SNMP. Examples of such technologies were CMIP, TMN, DMI,
Corba, JMX, DEN and WBEM. Fortunately, and well in time for this IM, a new
technology appeared at the horizon: web-services. Web-services is the name
for a set of W3C standards of which the most important ones are SOAP and
WSDL. These standards are supported by the main IT companies, and every
day new products enter the market. In this panel we will have an instructive
and entertaining discussion between experts who argue that web-services are
the most promissing technology to replace SNMP, and other experts who argue
that web services is nothing more than just another hype.

Panel 2: Overlay Networks and Management: A New Solution or Technology Recap?
Chair: Ehab Al-Shaer, De Paul University, Chicago, USA

The overlay networks architecture provides a virtual network on the top of an underlying substrate physical network. The main goals of overlay networks are to extend the Internet (IP) service delivery and improve the contents accessibility on the Internet. In addition, the network overlay abstraction provides for flexible and extensible application-level management techniques that can be easily and incrementally deployed despite the underlying network protocols/services.

Controversial Issues:

• Is overlay networks a new solution for real problems or a rehash of existing solutions applied in application level?
• Does overlay networks enable easy deployment with minimum cost or, in the opposite, it complicates the management tasks as we transfer network services to applications?
• What kind of applications would or would not benefit from the overlay network abstraction?
• Is service and network-aware applications in overlay networks sound the right approach to improve service delivery or working on improving the network services is the proper approach (i.e., network simplicity vs. quality of service delivery)
• Overlay network architecture might facilitate end-to-end management and control, but what about network resource management required to support overlay networks?
• Overlay networks require sufficient monitoring and measurement of the underlying networks and services. Does this become intrusive and therefore cost more to build end-to-end services? Isn’t the case that the applications will become the real bottleneck, instead of networks?
• Are overlay networks manageable? How? Propitiatory or MIB-based? How does this technology impact (positively or negatively) management and control of networks and services?
  

This panel will attempt to address these and other issues in order to evaluate and assess overlay networks infrastructure and services. Panelists will use examples of existing overlay networks implementations as case studies in their discussion. They will also share their vision about the future and research directions of overlay networks.

Potential Panelists:
- Ehab Al-Shaer, DePaul University (Panel Chair)
- Yatin Chawathe AT&T Research, USA
- Akhil Sahai, HP Labs, USA
- Burkhard Stiller, ETH Zurich, Switzerland

Panel 3: Resource Management for Enterprise Application Grids
Chair: Jerry Rolia (HP)

Panelists: Sharad Singhal (HP), Joseph Hellerstein (IBM), Robert Welland (Microsoft), Andrew Trossman (Think Dynamics), Petre Dini (CISCO)

Advances in programmable storage and ethernet networks have enabled programmable data centers (PDC). PDCs are tightly coupled pools of resources that enable the automated deployment of multi-tier infrastructure. Resources such has hosts, firewall and load balancing appliances, storage, and networking can be assigned to multi-tier applications as needed and relenquished by applications when they are no longer needed. This enables the future development of Grids for enterprise applications where resources are allocated to applications based on their time-varying needs. This panel discusses requirements for enterprise application grids and PDCs, gives an overview of resource management issues, and presents some possible approaches towards resource management.

Panel 4: Security and Privacy: How can we resolve the conflicts of
law enforcement and freedom lovers?
Chairs: Rob Kolstad, Executive Director, SAGE, USA

Panelists: - Richard Salgado, Department of Justice, USA - Lee Tien,
Senior Staff Attorney, Electronic Frontier Foundation

Governments want to observe citizens and visitors. Freedom advocates cry out that spy satellites,
TV cameras everywhere, email monitoring, and credit-card correlation are just too invasive of privacy. Why spy on people who aren't guilty or even suspected of everything? But it's abundantly clear that terrorism is a reality, and terrorism is undisputably wrought by terrorists. How can they be identified? Come hear what two world-famous advocates have to say on the topic. Moderated by Rob Kolstad, never known to shrink from asking difficult questions, this panel should provide keen insight into the ongoing debate of freedom vs. privacy in a world where data collection costs continue to spiral towards zero.

Panel 5: Intrusion Detection Management: are we reinventing the wheel ?
Co-Chairs: Marc Dacier, Felix Wu, University of California at Davis, USA

During the last 2 years, a new market has emerged for so-called 'intrusion detection management solutions'.
These systems aim at providing tools and techniques to deal with the very large number of alerts created by the intrusion detection tools
being deployed in many companies. The need for automated tools that can automatically filter, analyze, correlate and even react to these
events is unquestionable. However, it is reasonable to ask if we really need new tools. Why can't we simply reuse existing
"event management systems" that are familiar to the network and system management community ? What is so unique to these security
events and to their treatment, if anything ? These are a few of the questions that will be discussed by the panelists.
