Tutorial 1: Device Instrumentation for Performance Monitoring and its Application in Service Level Management
Alexander Clemm, Cisco Systems, San Jose, EUA
Resumo: Starting by describing typical business cases, this session will explore how to use device management instrumentation features to improve visibility into the network. We will discuss monitoring standards, communication approaches between the device and the NMS applications, and vendor implementations by taking Cisco as an example. Features covered in details include MIBs, NetFlow/IPFIX, IP SLA, NBAR, etc. We provide also an introduction to service level management and discuss how techniques for performance monitoring can be applied to both validate and ensure service level objectives are being met. The tutorial will include several practical examples from data, voice, and security domains that illustrate those techniques, including monitoring of specific service level objectives and capacity planning.

Tutorial 2: Gossip Protocols for Large-Scale Distributed Systems
Prof. Alberto Montresor, University of Trento, Itália
Resumo: Gossip protocols were first proposed by Demers at al. in 1987, to solve the problem of disseminating information among replicated databases. Since then, gossip protocols have proven to be able to solve a large collection of problems in the field of large-scale distributed systems, ranging from distributed aggregation to topology management, from load balancing to function optimization, etc. In this tutorial, we will review the field of gossip-based computing, discussing their robustness, performance and security.
Bio: Alberto Montresor is Associate Professor of Computer Science at the University of Trento (Italy) since 2005. He earned his Ph.D. degree from University of Bologna (Italy) in 2000. He is author of more than 50 papers in conferences and journals, in the field of distributed systems and peer-to-peer computing. He served as program chair and general chair of the IEEE P2P Conference in 2006 and 2007, respectively.
Tutorial 3: IT Service Management: Best Practices and Research Challenges
Claudio Bartolini, HP Labs Palo Alto, EUA
Resumo: The importance and difficulty of managing IT resources and services is driving IT organizations to adopt best practices developed over the last few years. The paradigm being used to project IT to the enterprise and its clients, partners and suppliers is the "IT Service". The tutorial examines IT Service Management (ITSM) in its various aspects. The complete lifecycle of a service is covered, including service strategy, service design, service transition, service operation and continual service improvement. Best practices for service management are examined with the help of the very popular IT Infrastructure Library (ITIL) framework in its latest version (v3).
Research efforts in the emerging discipline of Business–driven IT management (BDIM) aim at managing enterprise IT infrastructure and services according to ITSM best practices, and at the same time at improving business results at the same time. BDIM is based on mappings between IT technical performance metrics and business relevant metrics and exploit the linkage to provide decision support to IT management so as to maximize business value and IT-Business alignment. As an example, the number of successfully executed IT infrastructure changes can be mapped to financial results due to the service disruption experienced by customers when the changes take place.
The first part of this tutorial covers the current state of ITIL and ITSM, briefly touching on another best practices framework: COBIT – Common Objectives for IT. The second part of the tutorial maps the state-of-the-art in BDIM resaerch. The tutorial will cover definitions of BDIM, challenges posed by IT-business alignment and will provide concrete application examples as well as a description of current BDIM tools available.
The tutorial provides a mix of practical aspects, recent research results and descriptions of real tools concerning ITSM and BDIM. The attendee will understand and appreciate the terms ITSM, ITIL, IT governance, COBIT, and will gain familiarity with important IT processes dealing with service design, service transition and service operation.
