TUTORIALS 

Abstract
Network Virtualization is one of the main concept on which the next generation network will be based. Many research groups in the US, Europe and elsewhere in the world are investing on different aspects of virtualized Network; and many providers and vendors are very interested in exploring how this concept and associated technologies would help solve their business problems and create new growth opportunities. This tutorial will provides an introduction to the main research challenges of network virtualization (NV) be answering to following questions: how to discover and advertise the network resources; how to create and manage an slice or node across diverse resources; how does virtualization extend the Wireless and Optical links; how to implement virtualization across diverse resources and across layers of protocol stack; how to manage slice; what kind of service the network infrastructure providers will offer to the network providers, what kind of capabilities are enabled by infrastructure virtualization. Behind those research challenges, there is a need to implement this virtualized node in order to validate and experiment this new infrastructure. This implementation will require revisiting some very important Hardware and OS concepts such as VMM, Hypervisor, FPGA, Network Processor, Models of resource isolation, resource scheduler, etc. We will introduce during this tutorial those concepts, which will be need for sharing of firmware resources between the different slice processing, memory, IO and bandwidth sharing. And finally, we will review the main architectures proposed by the different projects.

Abstract
The main goal of the tutorial is to draw connections between active and passive approaches to network performance measurement and analysis. Active approach is also referred to as probing and is based on sending packets into the network and inferring its end-to-end performance at the other end of the path. Passive analysis is almost equally shared between the worlds of SNMP and NetFlow. When the term “network performance” is used together with verbs “measure”, “analyze”, or even “manage”, it is impossible to tell whether active or passive (according to definitions above) method is to be undertaken. In recent years, the scope and use of active measurement is increasing while passive methods continue to improve on efficiency. Yet, to the day, a paper or a talk on the topic has to clarify whether the measurement is active or passive, and, thus, kind of “pick a side”. In reality, as well as in some recent research works in the area, the two can be used together, augmenting each other’s capabilities. With network activities becoming truly global through distribution and dynamic topology, it is hard for a network activity to be contained within a single AS. End-to-end paths today average between 6 and 11 hops in length and can span from 4 to 6 ISPs from one end to the other.
Clearly, passive network performance analysis is not very helpful simply because users at path ends or event individual ISPs along the path do not have administrative access to routing equipment on the whole path.هOn NGN side, although NGN networks have already been commissioned in many countries, the area of network performance is still not complete in NGN standards. The two areas on the topic are dubbed “Network Performance Measurement” and “Network
Performance Measurement Management” in NGN and is reflected in several documents, most of which are still in draft stages. The delay in understandable, - network performance measurement on long end-to-end paths requires continuous inter-AS cooperation. This is clearly too sudden a change for providers.

Abstract
Grid computing technologies are being applied as an affordable method to clusterفcomputational power together. These structures aim to support service applications by grouping devices and shared resources in one large computational unit. However, the management complexity grows proportionally to the number of resources being integrated. From a given point up, manual management of large grid structures is unfeasible. This scenario calls for automated management methods to support availability, quality of service and optimized configurations. This tutorial presents the design of a grid computing management system based on autonomic elements, which aims to promote characteristics of self-management.
Providing security in a distributed system requires more than user authentication with passwords or digital certificates and confidentiality in data transmission. Rigorous control of the executed tasks is needed in order to prevent malicious users from breaking policies, to identify the use of stolen passwords, and also to make possible rapid detection of known attacks. In this tutorial, a solution for intrusion detection in grid and cloud computing environment is presented in which audit data is collected from the cloud and two intrusion detection techniques are applied. Analysis for anomaly detection is performed to verify if user actions correspond to known behavior profiles and knowledge analysis is performed to verify security policy violations and known attack patterns. This approach was evaluated in terms of performance results.
There is no consensus about what exactly cloud computing is, but some characteristics are clearly repeated. It is a new distributed computing and business paradigm. It provides computing power, software and storage and even a distributed data center infrastructure on demand. To make these characteristics viable, it makes use of existing technologies, such as virtualization, distributed computing, grid computing, utility computing and Internet. In this tutorial, we investigate what are the security problems involving this new paradigm, trying to obtain what are the main security problems cited in the available literature and, when possible, trying to point some directions in how to solve them.

Abstract
The current Internet is a critical infrastructure thatنhasنtransformed society. However, its original architecture was not designed to meet many of today’s demands; next generation networks (NGNs) and requirements of the future Internet(s) exacerbate this problem. In particular,هthe Internet faces manyهdiverseهchallenges,هincluding economic and societal requirements, which have a profound effect on the architecture of the Internet. While several significant “future Internet” initiatives have been initiated across the world, management issues tend to be ignored. Management has been viewed as something that cannot command high revenues, and hence investment and innovation has been stymied. This has now caused problems in deploying new services, such as cognitive radio, which requires additional investment in developing new regulations to govern these services. In addition, different contexts usually have different needs and interests, and different stakeholders have not been able to agree in how to fix the problems that have arisen. In order to address the technical, business, societal, and other issues that have arisen, aفholisticفsolution is necessary. This tutorial will first examine the original design focus of the Internet, and then show how some of the fundamental architectural assumptions of this original design have given rise to current and future problems in NGNs and the future Internet. Next, the business, technical, and societal requirements for NGNs and the future Internet will be examined. The tutorial will then focus on existing management proposals and the role that different standards play. The heart of the tutorial will then describe a new approach for managing NGNs and the Future Internet, and finish with conclusions and references. Each of these sections will use several examples, along with current research results, to enable the tutorial participant to see how theory is applied in academic and industrial settings.

Abstract
The business, technical, and even societal aspects of systems have increased dramatically in complexity, requiring new technologies, paradigms and functionality to be introduced to cope with these challenges. This increase in complexity has made it almost impossible for a human to manage the different operational scenarios that are possible in today’s communication systems. Autonomic systems were designed to manage complexity. This tutorial provides an in-depth review of autonomic networking, and features the use of several demonstrations to illustrate the technical details taught in the tutorial. The automation of network management operations, such as configuration, will be emphasized. This tutorial uses a novel autonomic architecture, called FOCALE, to illustrate the complexities in managing wired and wireless networks, and provides the tutorial participant with a relatively deep understanding of the source of these problems and a variety of tools that can be used to solve these problems. The tools examined by this tutorial include: (1) the use of information modeling (in particular, DEN-ng) to harmonize and translate between the different languages and management methods used by different devices; (2) the use of ontologies (in particular, DENON-ng) to augment the facts defined by models with formal definitions that enable machine-based learning and reasoning to be used; (3) enhancements and alternatives to the standard “model-analyze-plan-execute” control loop used to orchestrate behavior; (4) the use of a novel context-aware policy management approach to enable the services and resources of a network to change in order to meet the demands of changes in current environments, user needs and environmental conditions; (5) how to represent different semantics associated with network configuration and service demands. The theoretical lessons in this tutorial will be reinforced with use cases and practical examples. This tutorial is important, because the potential of autonomics applied to networking has not yet been fully realized. While automation of tasks is important, autonomics can be used for many additional purposes, including integrating semantics, ensuring compliance with regulatory and other types of policy rules, and orchestrating behavior.

Abstract
This tutorial presents a generic methodology for measurements-based performance evaluation of a mobile computing and/or communication system and its service(s). The performance evaluation aims at analysis of, for example, system’s bottleneck or scalability characteristics or at analysis of responsiveness of its selected mobile service. The presented methodology has been derived from previous studies on performance of communication networks.The methodology is outlined with aim to perform (practical) measurements, as opposite to (theoretical and widely used) simulations or modeling, as the latter not necessary disclose the nuances of the system performance as experienced by the system user in his natural environment. The importance of the proposed methodology and the necessity of its usage are emphasized, with the aim of understanding of the user’s experiences and eventual reconfiguration or even redesign of the system. The methodology includes detailed steps for objectives determination, system instrumentation, measurement execution and performance evaluation activities. The participants will learn in-depth these methodological steps from theoretical and practical point of view, as the tutorial illustrates use of the methodology for performance evaluation of MobiHealth system and its vital sign tele-monitoring service provided to a mobile patient.

Abstract
All developed countries are facing tremendous social challenges in the near future. Among these challenges, the increase of aging population is a major problem for all healthcare systems that have been hardly built during many decades. This increase of elderly is leading to an increase of the number of people with impairments, disabilities or chronic deceases that make them dependent. This situation is unsustainable for many families and countries and will certainly lead to the collapse of their healthcare system if any actions are not taken very quickly. Fortunately, we have seen recently an important advance in new technologies that could be used to provide innovative solution in this area. This market is very promising for ICT (Information and Communication Technologies) as these technologies could be used to address a number of situations by anticipating injuries, serious health accidents and facilitate the care and independence of elderly helping them to leave safely and independently in their home.This tutorial will firstly present the challenges of healthcare systems in future society. It will then presents a state of art of existing initiatives providing solutions to reduce healthcare cost by improving the remote monitoring of patients and elderly. Next, the presentation will focus on the technologies that will facilitate the improvement of these solutions (bio and nano technologies, networking technologies, autonomic technology). The next part of the presentation will address the challenges posed by the system in term of decision-making distribution and pro-active control and the need for a more autonomic approach. The presentation will then focus on a particular case study that is heart anomaly monitoring and detection and will show how a service around this particular disease can be deployed. The perception of such as system from people is very important and thus the tutorial will address the problem of Quality of Health. Finally, the presentation will present a real system that is under development at POSTECH (Korea) in the frame of the WCU project.
