Tutorial 1: Pervasive Computing and Management (ASEM Hall 203A)
Duration: Monday, 19 April 2004, 8:30 - 12:00
|

Abstract: The vision of pervasive and ubiquitous computing was set forth in the early 90's, calling for a world of people and environments augmented with computational resources that provide access to information and services anytime, anywhere. Since then, part of this vision has been realized, with the arrival of small-sized smart devices (personal digital assistants, mobile phones, etc.) that have become an integral part of our everyday life.
In addition to devices oriented towards humans, pervasive computing environments also include networks of devices (sensors) embedded in their physical environment that gather information, perform local computations, and communicate with other devices and centralized computing resources. Such systems are finding usage in a variety of applications, including remote sensing, agriculture, military and aerospace, and disaster recovery.
The first part of this tutorial presents a comprehensive overview of pervasive computing and its evolution in the last 10 years. Particular attention is given to three areas where most research and development work has focused: natural interfaces (displays, speech, input devices), context awareness, and automated capture and access of live experiences. In addition, we explore a number of systems issues common in the development of pervasive applications, such as networking techniques for creating a pervasive communications infrastructure (especially in the presence of intermittent connectivity), middleware and operating system support, security and privacy.
The second part provides an overview of the still nascent field of management of pervasive environments. We outline the challenges and present the latest work in the area: problem domains, architectures and implementations.

Tutorial 2: Managing Mobile Ad Hoc Networks (ASEM Hall 203B)
Duration: Monday, 19 April 2004, 8:30 - 12:00
|
|
Abstract: Tomorrow¡¯s mobile ad hoc networks emphasize adaptable and flexible networks that automatically adapt to the user¡¯s needs. Such adaptability and flexibility requires mobile networking capabilities significantly beyond what is possible with currently fielded technology. There is a need for a variety of services, including automatic neighbor and link quality discovery, automatic network reconfiguration, quality of service guarantees, precedence and priority marking, and automatic routing and relaying of traffic. The development and implementation of mobile networking protocols and agile management capabilities is a technical challenge. Current network management technology predominantly supports static, pre-planned legacy networks with only modest capabilities for automated and adaptive (re-)configuration and monitoring of network facilities (e.g. nodes, servers and gateways) and their roles and relationships. In the future, mobile ad hoc networking calls for flexible composition and on-the-fly operational adjustments to adapt to dynamic and unpredictable conditions. This tutorial will discuss these management challenges and will outline solutions to the above problems that address the unique characteristics of mobile ad hoc networks. The tutorial will cover the following topics:

Tutorial 3: Traffic Engineering and Quality of Service Management for IP-based Next Generation Networks (ASEM Hall 208A)
Duration: Monday, 19 April 2004, 8:30 - 12:00
|
|
Abstract: Next Generation IP-based Networks will offer Quality of Service (QoS) guarantees by deploying technologies such as Differentiated Services (DiffServ) and Multi-Protocol Label Switching (MPLS) for traffic engineering and network-wide resource management. Despite the progress already made, a number of issues still exist regarding edge-to-edge intra-domain and inter-domain QoS provisioning and management. This tutorial will focus on architectures and frameworks for the management and control of such networks, including the following aspects: emerging Service Level Agreements (SLAs) and Service Level Specifications (SLSs) for the subscription to QoS-based services; management protocols for off-line service negotiation and signaling mechanisms for the dynamic invocation of service instances (e.g. RSVP to the network edge); approaches for the derivation of a traffic matrix based on subscribed SLAs/SLSs and monitoring data; algorithms for off-line traffic engineering and provisioning through MPLS or through plain IP routing with QoS extensions; algorithms for dynamic resource management to deal with traffic fluctuations outside the predicted envelope; and a policy-based overall framework for traffic engineering and service management. Finally, ongoing work towards inter-domain QoS provisioning will be presented. In all these areas, recent research work by the author and other researchers and working groups will be presented, with pointers to bibliography.
This tutorial will explain only briefly fundamental underlying technologies such as DiffServ and MPLS and can be combined with another tutorial that covers such technologies in detail, e.g. the one given by Dr M. Brunner in recent IM and NOMS events. In the absence of such a preceding tutorial, this tutorial could include more introductory material on key technologies.

Tutorial 6: Managing Firewall and Network-Edge Security Policies (ASEM Hall 208A)
Duration: Monday, 19 April 2004, 13:30 - 17:00
|
|
Abstract: Firewalls are core elements in network security. However, managing firewall rules, particularly in multi-firewall enterprise networks, has become a complex and error-prone task. Firewall filtering rules have to be written, ordered and distributed carefully in order to avoid firewall policy conflicts (or anomalies) and network vulnerability. Therefore, adding or modifying rules in any firewall requires a thorough intra- and inter-firewall analysis to determine the rule location (which firewall) and position (what order in the firewall policy) in the network in order to produce anomaly-free firewall policies.
In this tutorial, we first comprehensibly identify all anomalies types that could exist in a single- or multi-firewall environments. We then present a set of techniques/tools to automatically discover and rectify policy anomalies in centralized and distributed legacy firewalls. The tutorial provides the following:

Tutorial 7: Autonomic Networking - Theory and Practice (ASEM Hall 203A)
Duration: Friday, 23 April 2004, 8:30 - 12:00
|
|
Abstract: A new genre of management applications is required to accommodate current and future uses of network services. The key to solving this problem is to realize that currently, network operation is divorced from how the business operates, and that current approaches don't address this problem. This tutorial will discuss the four key foundational elements of solving this problem - use of standard information models, the transformation of these information models to a set of data models to suit the characteristics of different management data, the holistic combination of policy and process management, and a distributed interface oriented architecture that can realize the power of the previous three elements.
The foundation for this tutorial lies in work done in the TeleManagement Forum's NGOSS program and the DEN-ng information model, tempered by current research in autonomic computing. After briefly covering these areas, the tutorial will concentrate on new research that focuses on implementing an autonomic network - an area that has been overlooked in current research. New enhancements on the OMG's Model Driven Architecture initiative will be described that enable code to be generated from formal models. This will be supplemented with work on holistically combining process and policy management, and implementing this in a distributed service-oriented architecture. Real-life examples will be used to reinforce the contents of this tutorial. In addition, a case study that follows the development of an MPLS VPN will be used in each section to show how the concepts presented in this tutorial can be used to solve today's business problems.

Tutorial 8: Integrated Management from E-Business Perspective (ASEM Hall 203B)
Duration: Friday, 23 April 2004, 8:30 - 12:00
|
|
Abstract: This tutorial (based on the recent book by Pradeep Ray) is organized into four parts that discuss four viewpoints of Integrated Management from E-Business Perspectives, namely 1. Business Viewpoint 2. Methodology and Process Viewpoint 3. Architectural Viewpoint 4. Technology and Standards Viewpoint Part 1 provides a brief review of the evolving e-business models and itdiscusses the problem of integrated management from the business perspective in terms of the four key management dimensions for e-business; people, organization, process, and technology. The objective of Part 2 is to show the need for a holistic perspective on e-business services, integrating business processes with appropriate techniques to assist in the quantification of qualitative business parameters, such as service quality. This part also presents an approach to the study of the management of diverse services through a common 8-stage methodology. While a methodology gives a general guideline for development, architecture is needed to realize the design through software building blocks. Hence Part 3 discusses architectures for e-business management in a top-down manner. The discussion covers various viewpoints on e-business management, namely the Process View, Transaction View, and the Infrastructure View. Part 4 discusses various emerging technologies and standards covering the entire e-business constituent areas discussed in Part 3. This part discusses various network, systems and application management standards, and their integration, illustrated by a case study of e-business in telecommunication industry (e-telco).

Tutorial 9: Traffic Measurement in IP Networks (ASEM Hall 208A)
Duration: Friday, 23 April 2004, 8:30 - 12:00
|
|
Abstract: Traffic Measurement in the Internet, particularly traffic flow measurement, is an area of rapid growth in recent years, although the issue is not new at all. But many tools have been developed and methodology and technologies have been improved significantly. This tutorial gives an overview of methods, technologies and existing tools for traffic measurements. It starts with basic requirements, constraints, and problems of metering IP packets related to the Internet protocol and to common transport protocols. Then capturing IP packets at link layer level and at network level is discussed. For traffic metering, there exist several IETF standards and other de-facto standards. The tutorial gives and overview of these as well as of common low-level metering tools.
On higher levels of IP traffic measurement, a large variety of tools, frameworks, and systems can be found supporting graphical display of measured flow data, integration and correlation of measurements from different locations, and integration with applications such as traffic engineering and accounting. For the tutorial, a representative subset of these was selected and will be presented. Finally, and outlook is given including recent developments, current activities and challenges ahead.

Tutorial 10: Rethinking Manageability - Advances and Emerging Paradigm Shifts in Managing Intelligent IP Networks (ASEM Hall 203A)
Duration: Friday, 23 April 2004, 13:30 - 17:00
|
|
Abstract: Rapid advances in networking technologies are changing the way we manage IP networks. Previously, network vendors focused on building boxes whose main features were to switch or route traffic as fast as possible. Management is based largely on CLI, designed specifically with human users in mind, and SNMP with a proliferation of thousands of special-purpose MIBs. Today as the Internet is transforming the IP networks into a global business service creation platform, this paradigm runs increasingly into limitations. While current initiatives such as policy-based management and CIM/DEN are elevating the scope of the management applications to beyond network element and stovepipe focus, little attention has been paid to manageability of the network infrastructure itself and the needs to evolve management instrumentation. This tutorial presents a view of the IP network management problem from the perspective of the network itself. It focuses on how to address enhanced manageability requirements in the network infrastructure. This includes what can and should be instrumented inside a network element, and what can and should be instrumented with a scope that goes beyond the individual network element to result in more general ¡°manageability services¡± provided by the network. We will discuss the relevance of manageability as a business driver and provide an in-depth analysis of the various factors that contribute to manageability. After this, techniques will be presented that can be applied to enhance manageability, also in light of increased focus on applications such as on-demand services, managed services, and plug-n-play networking. We will also discuss the role of certain technologies such as XML and Netflow in the emergence of a new generation of management interfaces. Finally, scenarios will be used to illustrate how the resulting advances in manageability facilitate not only the development of management applications, but ultimately result in networks that are more autonomous and ¡°self managing¡±, and less complex and costly to operate than the norm today.
