Tutorial 1: Device Instrumentation for Performance Monitoring and its Application in Service Level Management
Tuesday, 25/05, 08:30-12:30, Locatteli Auditoruim

Alexander Clemm, Cisco Systems, San Jose, USA

Abstract: 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 p erformance 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.

Short Bio: Alexander Clemm is a Principal Engineer at Cisco in San Jose, California, where he is responsible for the architecture of manageability and embedded management capabilities of IOS and derivatives.  In addition, he is on the Adjunct Faculty of Santa Clara University.  Alex is a regular member of the Technical Program and Organizing Committees of IEEE's flagship network management conferences and served as co-chair of Manweek 2007, DSOM 2007, and the TPC of IM 2005.  He authored the text book "Network Management Fundamentals" and has over 25 patents issued or pending.  Alex received a Ph.D. Degree in Computer Science from the University of Munich, Germany, and a Master's Degree in Computer Science from Stanford University.

Keynote 1: New Trends in Intelligent Manageability Instrumentation
Tuesday, 25/05, 14:00-15:30, Locatteli Auditorium

Alexander Clemm, Cisco Systems, San Jose, USA

Abstract: Manageability in networked devices is at a cross-roads.  Approaches in which management intelligence is pulled out of the network and centralized compete with approaches in which intelligence is increasingly pushed into the network and decentralized; at the same time, myriads of new management interfaces are appearing.  This presentation will explore some of the latest trends in embedding greater intelligence into the network for improved and more proactive service assurance, including techniques for forecasting, baselining and anomaly detection.

Short Bio: Alexander Clemm is a Principal Engineer at Cisco in San Jose, California, where he is responsible for the architecture of manageability and embedded management capabilities of IOS and derivatives.  In addition, he is on the Adjunct Faculty of Santa Clara University.  Alex is a regular member of the Technical Program and Organizing Committees of IEEE's flagship network management conferences and served as co-chair of Manweek 2007, DSOM 2007, and the TPC of IM 2005.  He authored the text book "Network Management Fundamentals" and has over 25 patents issued or pending.  Alex received a Ph.D. Degree in Computer Science from the University of Munich, Germany, and a Master's Degree in Computer Science from Stanford University.

Keynote 2: Cloudy Wheather for P2P, with a Chance of Gossip
Tuesday, 25/05, 18:00-19:00, Locatteli Auditoruim

Prof. Alberto Montresor, University of Trento, Italy

Abstract: Two of the Internet buzzwords of the the last decade, peer-to-peer (P2P) and cloud computing, hold similar promises: the (virtually) infinite availability of computing and storage resources. But there are important differences: the cloud provides you with highly-available resources, but at a cost; P2P resources are for free, but high level of churn can affect reliability. Will it be possible to mix the advantages of both worlds, exploiting the free resources of a P2P environment and reverting to the cloud whenever such resources are not sufficient to guarantee a minimum level of service? This talk tries to provide a positive answer.

Short 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.
